Android系統應用開發（六）Android framework系統預設設定修改
阿新 • • 發佈：2019-01-29
launcher 總結:
1、launcher的佈局太居中，要想兩邊拉伸
2、或者不想改數目：<\packages\apps\Launcher2\res\values\dimens.xml> <dimen name="apps_customize_pageLayoutPaddingLeft">40dp</dimen> <dimen name="apps_customize_pageLayoutPaddingRight">40dp</dimen> apps tab欄的寬度（Launcher2 icon 數目、大小） \packages\apps\Launcher2\res\layout-sw720dp\workspace.xml> launcher:cellCountX="10" launcher:cellCountY="6"
<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizeTabHost.java>
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
mTabs.getLayoutParams().width = contentWidth + 108;
<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml> <dimen name="workspace_cell_width">110dip</dimen> <dimen name="workspace_cell_height">110dip</dimen> <dimen name="apps_customize_cell_width">110dp</dimen> <dimen name="apps_customize_cell_height">110dp</dimen>
4、裡面icon的大小：
<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>
<dimen name="app_icon_size">80dp</dimen>
5、workspace沒有拖動，第二頁第一個icon出現在第一頁的最右邊：
加大workspace的寬度，或間距： workspace的paddingLeft、paddingRight： <\packages\apps\Launcher2\res\values-sw600dp-land\dimens.xml> <dimen name="workspace_left_padding">50dip</dimen> <dimen name="workspace_right_padding">50dip</dimen> workspace兩屏間距： <dimen name="workspace_page_spacing">100dp</dimen> 修改workspace的字型大小： 如果沒有就新增： <\packages\apps\Launcher2\res\values-sw480dp\styles.xml> <style name="WorkspaceIcon.Landscape"> <item name="android:textSize">13sp</item> </style>
6、加wallpaper：
1.<\packages\apps\Launcher2\res\values-sw600dp\wallpapers.xml>
加wallpaper的名字
2.<\packages\apps\Launcher2\res\drawable-nodpi>
加如wallpaper
7、gallery的widget預設新增到workspace上：
<\packages\apps\Launcher2\res\xml\default_workspace.xml>
<!-- Middle screen [2] -->
<appwidget
launcher:packageName="com.android.gallery3d"
launcher:className="com.android.gallery3d.gadget.PhotoAppWidgetProvider"
launcher:screen="2"
launcher:x="1"
launcher:y="0"
launcher:spanX="3"
launcher:spanY="3" />
<\packages\apps\Gallery2\src\com\android\gallery3d\gadget\PhotoAppWidgetProvider.java>
@Override
public void onUpdate(Context context,
for (int id : appWidgetIds) {
if(id == 2){
helper.setWidget(id,WidgetDatabaseHelper.TYPE_SHUFFLE, null);
}
}
8、在桌面上新增網頁的快捷方式：
<\packages\apps\Launcher2\res\xml\default_workspace.xml>
<shortcut
launcher:title="@string/application_name"
launcher:icon="@drawable/ic_no_applications"
launcher:uri="http://www.aaa.com"
launcher:screen="0"
launcher:x="0"
launcher:y="3" />
9、在桌面上預設放資料夾：
<\packages\apps\Launcher2\res\xml\default_workspace.xml>
<folder
launcher:screen="2"
launcher:x="2"
launcher:y="2"
launcher:title = "@string/application_name" >
<favorite
launcher:className="com.android.deskclock.DeskClock"
launcher:packageName="com.android.deskclock"
launcher:container="1"
launcher:x="0"
launcher:y="0" />
<favorite
launcher:className="com.android.calculator2.Calculator"
launcher:packageName="com.android.calculator2"
launcher:container="1"
launcher:x="0"
launcher:y="0" />
</folder>
10、桌面上新增快捷方式，點選播放視訊：
<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>
<shortcut launcher:title="@string/application_name"
launcher:icon="@drawable/ic_launcher_application"
launcher:uri="file:///mnt/sdcard/external_sdcard/1...playermenu;end"
launcher:screen="2"
launcher:x="1"
launcher:y="1" />
1.寫google顯示的apk:
GooglePlayShow的activity：
ComponentName componentname = new ComponentName("com.android.vending", "com.android.vending.AssetBrowserActivity");
packagemanager.setComponentEnabledSetting(componentname, 1, 1);
componentname = new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity");
packagemanager.setComponentEnabledSetting(componentname, 2, 1);
2.<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>
} else if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {
if (!replacing) {
if(packageName.equals("com.example.googleplayshow")){
context.startActivity(new Intent().setComponent(new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity")).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
}
op = PackageUpdatedTask.OP_ADD;
} else {
op = PackageUpdatedTask.OP_UPDATE;
}
}
隱藏google search：
<\packages\apps\Launcher2\src\com\android\launcher2\Launcher.java>
private void setupViews() {
mSearchDropTargetBar = (SearchDropTargetBar) mDragLayer.findViewById(R.id.qsb_bar);
mSearchDropTargetBar.hideSearchBar(false);
void showWorkspace(boolean animated, Runnable onCompleteRunnable) {
//mSearchDropTargetBar.showSearchBar(wasInSpringLoadedMode);
<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>
updatePackages裡面新增：
if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){
mWidgets.add(widget);
}
<\packages\amlogic\Launcher2\res\values\dimens.xml>
<dimen name="app_widget_preview_padding_top">10dp</dimen>
修改widget的text的size：
<\packages\amlogic\Launcher2\res\layout\apps_customize_widget.xml>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/widget_name"
android:textSize="20sp" />
需要該app的packageName，例如要隱藏settings：
<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>
private void loadAllAppsByBatch() {
apps = packageManager.queryIntentActivities(mainIntent, 0);
ResolveInfo removeApp = null;
for(ResolveInfo info:apps){
if(info.activityInfo.packageName.equals("com.android.settings")){
removeApp = info;
}
}
if(removeApp != null){
apps.remove(removeApp);
}
15、launcher中隱藏多個app：紅色為改動部分
<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>
private void loadAllAppsByBatch() {
final PackageManager packageManager = mContext.getPackageManager();
List<ResolveInfo> apps = new ArrayList<ResolveInfo>();
List<ResolveInfo> allApps = null;
int N = Integer.MAX_VALUE;
int startIndex;
int i=0;
int batchSize = -1;
while (i < N && !mStopped) {
if (i == 0) {
mAllAppsList.clear();
final long qiaTime = DEBUG_LOADERS ? SystemClock.uptimeMillis() : 0;
allApps = packageManager.queryIntentActivities(mainIntent, 0);
for(ResolveInfo info : allApps){
if(info.activityInfo != null
&& !info.activityInfo.packageName.equalsIgnoreCase("com.android.email")
&& !info.activityInfo.packageName.equalsIgnoreCase("com.android.providers.downloads.ui")
&& !info.activityInfo.packageName.equalsIgnoreCase("com.adobe.flashplayer")){
apps.add(info);
}
}
settings 問題總結:
1.入口，設定分屏顯示
frameworks\base\core\res\res\values\bools.xml 下的 preferences_prefer_dual_pane 為true.
<bool name="preferences_prefer_dual_pane">true</bool>
<settings.java>
private void updateHeaderList(List<Header> target) {
if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {
target.remove(header);
}
3.預設字型：
public void readFontSizePreference(ListPreference pref) {
ActivityManagerNative.getDefault().getConfiguration()
系統的Configuration是從ActivityManagerService設定的：
<\frameworks\base\services\java\com\android\server\am\ActivityManagerService.java>
mConfiguration.setToDefaults();
fontScale = Float.parseFloat(SystemProperties.get("ro.fontScale","1"));
<\packages\apps\Settings\AndroidManifest.xml>
<application android:label="@string/settings_label"
android:icon="@mipmap/ic_launcher_settings"
android:taskAffinity=""
android:theme="@android:style/Theme.Holo"
android:uiOptions="splitActionBarWhenNarrow"
android:hardwareAccelerated="true">
<\frameworks\base\core\res\res\values\themes.xml>
<style name="Theme.Holo">
字型顏色
<item name="textColorPrimary">@android:color/primary_text_holo_dark</item>
加亮框的顏色：
<item name="activatedBackgroundIndicator">@android:drawable/activated_background_holo_dark</item>
觸控框的顏色：
<item name="listChoiceBackgroundIndicator">@android:drawable/list_selector_holo_dark</item>
左邊背景：
<item name="windowBackground">@android:drawable/screen_background_selector_dark</item>
右邊的背景：
<item name="detailsElementBackground">@android:drawable/panel_bg_holo_dark</item>
title的背景：
<item name="actionBarStyle">@android:style/Widget.Holo.ActionBar</item>
frameworks/base/services/java/com/android/server$ vi ./am/ActivityManagerService.java
大概839行 把int mProcessLimitOverride = -1;改成4(不得超過4個程序)
標準限制 對應 -1
不允許後臺程序 對應 0
不得超過1個程序 對應 1
不得超過2個程序 對應 2
不得超過3個程序 對應 3
6. 預設不要鎖屏，設定-安全--螢幕鎖定 (無)
overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml
<bool name="def_lockscreen_disabled">true</bool>
overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml
<string name="def_location_providers_allowed" translatable="false">gps</string>
改成
<string name="def_location_providers_allowed" translatable="false">gps,network</string>
常用修改一.
修改預設(Settting.apk中選項預設值一般存在於frameworks\base\packages\SettingsProvider\res\values\defaults.xml)
1. 預設勾選未知來源
<bool name="def_install_non_market_apps">false</bool>
2. 預設鈴聲, 通知, 鬧鐘音樂可以在system.prop 分別配置
ro.config.ringtone=Playa.ogg（預設鈴聲設定，檔案在/system/media/audio/ringtones把喜歡的鈴聲放這裡，比如123.MP3放入ringtones資料夾中，這裡程式碼改為ro.config.ringtone=123.mp3）
ro.config.notification_sound=regulus.ogg（預設提示音，檔案在/system/media/audio/notifications修改方法同上）
ro.config.alarm_alert=Alarm_Beep_03.ogg（預設鬧鈴，檔案在/system/media/audio/alarms修改方法同上）
3. 桌布不跟隨滑動
packages/apps/Launcher2/./src/com/Android/launcher2/Workspace.Java大概
875行
private float wallpaperOffsetForCurrentScroll()
修改 wallpaperOffsetForCurrentScroll的返回值。改成 return 0.5f;
二.隱藏或刪除某項
1.去掉設定中Wifi選項
device/amlogic/xxxref/xxxref.mk 檔案中
# Device specific system feature description
PRODUCT_COPY_FILES += \
$(LOCAL_PATH)/tablet_core_hardware.xml:system/etc/permissions/tablet_core_hardware.xml\
frameworks/native/data/etc/android.hardware.wifi.xml:system/etc/permissions/android.hardware.wifi.xml\ (刪除)
2.去掉設定中藍芽選項參考 wifi。在tablet_core_hardware.xml 刪除<feature name="android.hardware.bluetooth"/> 這一行
3. HDMI 部分
1）去掉HDMI選項在system.prop中加入 ro.hdmi.autoswitch=false
2）去掉480p
選項在prop中設定 ro.hdmi480p.enable=false
4. 去掉 powerwidget 中某一項以去掉 gps 為例
在packages\apps\Settings\res\layout\widget.xml 下，移除
<ImageView
android:layout_width="1dip"
android:layout_height="match_parent"
android:background="@drawable/appwidget_settings_divider_holo"
android:contentDescription="@null"
/>
<LinearLayout
android:id="@+id/btn_bluetooth"
android:layout_width="0dip"
android:layout_weight="1"
android:layout_height="match_parent"
android:paddingTop="12dp"
android:background="@drawable/appwidget_button_center"
android:clickable="true"
android:focusable="true"
android:orientation="vertical">
<ImageView
android:id="@+id/img_bluetooth"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:scaleType="center"
android:contentDescription="@null"
/>
<ImageView
android:id="@+id/ind_bluetooth"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:contentDescription="@null"
/>
</LinearLayout>
然後 com.android.settings.widget.SettingsAppWidgetProvider.java
註釋 views.setOnClickPendingIntent(R.id.btn_gps, getLaunchPendingIntent(context, BUTTON_GPS)); 這一行。
以去掉 "網路共享與行動式熱點" 為例根據"網路共享與行動式熱點" 這個關鍵詞在 values-zh_rCN 中搜索到的 key值，然後在AndroidManifest.xml 搜尋這個 key值。找到對於的Activity 配置移除 <categoryandroid:name="com.android.settings.SHORTCUT" /> 這一行。
6. 修改瀏覽器預設瀏覽器模式
packages\apps\Browser\res\xml-sw600dp\advanced_preferences.xml
<ListPreference
android:key="user_agent"
android:title="@string/pref_development_uastring"
android:entries="@array/pref_development_ua_choices"
android:entryValues="@array/pref_development_ua_values"
android:defaultValue="3"/>
修改 android:defaultValue="3" 具體的值參考一下選項
<string-array name="pref_development_ua_choices" translatable="false">
<item>Android</item>
<item>Desktop</item>
<item>iPhone</item>
<item>iPad</item>
<item>Froyo-N1</item>
<item>Honeycomb-Xoom</item>
</string-array>
<!-- Do not tranlsate. Development option -->
<string-array name="pref_development_ua_values" translatable="false">
<item>0</item>
<item>1</item>
<item>2</item>
<item>3</item>
<item>4</item>
<item>5</item>
範例
folder 放到最前面。launcher:container 的值是folder的資料庫中的id。一般從1開始。
<folder
launcher:screen="2"
launcher:x="1"
launcher:y="1"
launcher:title ="@string/application_name" >
<favorite
launcher:className="com.android.settings"
launcher:packageName="com.android.settings.Settings"
launcher:container="2"
launcher:x="0"
launcher:y="0" />
<favorite
launcher:className="com.fb.FileBrower"
launcher:packageName="com.fb.FileBrower.FileBrower"
launcher:container="2"
launcher:x="0"
launcher:y="0" />
</folder>
widget 範例
<appwidget
launcher:packageName="com.android.calendar"
launcher:className="com.android.calendar.widget.CalendarAppWidgetProvider"
launcher:screen="1"
launcher:x="0"
launcher:y="0"
launcher:spanX="2"
launcher:spanY="3" />
快捷方式範例
<favorite
launcher:packageName="com.android.settings"
launcher:className="com.android.settings.Settings"
launcher:screen="2"
launcher:x="1"
launcher:y="3" />
網頁快捷方式
<shortcut
launcher:title="@string/custom_google"
launcher:icon="@drawable/favicon_google"
launcher:uri="http://www.google.com/"
launcher:screen="3"
launcher:x="4"
launcher:y="1"/>
8. 系統自帶LatinIME 高階設定--按鍵音量設定修改預設值
java/res/values/keypress-volumes.xml
<string-array name="keypress_volumes" translatable="false">
<!-- Build.HARDWARE,volume -->
<item>amlogic,0.3</item> //加入這行。 把0.3改成自己的預設值。0.3代表30%
<item>herring,0.5</item>
<item>tuna,0.5</item>
<item>stingray,0.4</item>
9.lockscreen座標數字時鐘被遮住
請調整紅色的數字：
<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_tab_unlock_land.xml>
<!-- left side: status and music -->
<RelativeLayout
android:layout_height="match_parent"
android:layout_weight="0.5"
<!-- right side -->
<RelativeLayout
android:layout_height="match_parent"
android:layout_weight="0.5"
比如改成大：
<frameworks\base\packages\SettingsProvider\res\values\defaults.xml>
<fraction name="def_font_scale">115%</fraction>
11.沒有藍芽的平臺，去掉視窗小部件－設定快捷方式－拉到桌面顯示的“藍芽”選項
<\packages\apps\Settings\src\com\android\settings\OutputSettingsBroadcastReceiver.java>
public void onReceive(Context context, Intent intent)
{
// boot completed
if(intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED))
{
if(!context.getPackageManager().hasSystemFeature(context.getPackageManager().FEATURE_BLUETOOTH)){
ComponentName componentname = new ComponentName("com.android.settings", "com.android.settings.Settings$BluetoothSettingsActivity");
context.getPackageManager().setComponentEnabledSetting(componentname, 2, 1);
}
}
分別在一下資原始檔中新增自定義的標籤
packages\apps\Browser\res\values\strings.xml
<string-array name="bookmarks" translatable="false">
<item>Google</item>
<item>http://www.google.com/</item>
<item>Picasa</item>
<item>http://picasaweb.google.com/</item>
<item>Yahoo!</item>
<item>http://www.yahoo.com/</item>

<item>BBC</item>
<item>http://www.bbc.co.uk/</item>
</string-array>
packages\apps\Browser\res\values\bookmarks_icons.xml，
注意：這裡每個網站對應一個縮圖和一個favicon
<array name="bookmark_preloads">
<item>@raw/favicon_google</item>
<item>@raw/thumb_google</item>

</array>
對應的圖片在 packages\apps\Browser\res\raw
已增加 VideoPlayer 為例，
在frameworks/base/core/res/res/drawable-hdpi 下面
新增一個對應的png圖示
下面紅色為增加的部分。frameworks/core/res/res/values-sw600dp-land/arrays.xml
<item>@drawable/ic_lockscreen_unlock</item>
<item>@drawable/ic_action_assist_generic</item>
<item>@drawable/ic_lockscreen_camera</item>
- <item>@null</item>
+ <item>@drawable/ic_lockscreen_videoplayer</item>
</array>
<array name="lockscreen_target_descriptions_with_camera">

<item>@drawable/ic_lockscreen_camera</item>
- <item>@null</item>
+ <item>@drawable/ic_lockscreen_videoplayer</item>
</array>
<array name="lockscreen_target_descriptions_with_camera">

frameworks/base/policy/src/com/android/internal/policy/impl/LockScreen.java
case com.android.internal.R.drawable.ic_lockscreen_camera:
launchActivity(new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA));
mCallback.pokeWakelock();
break;
case com.android.internal.R.drawable.ic_lockscreen_videoplayer:
launchActivity(new Intent().setClassName("com.farcore.videoplayer", "com.farcore.videoplayer.FileList"));
mCallback.pokeWakelock();
break;
注意： 在 frameworks/base/core/res/ 中執行mm 。然後在frameworks/base/policy 中執行mm。看看能否編譯過。不行的話，在 在根目錄下 執行make update-api
13. 休眠策略
修改預設的休眠策略，請參考
frameworks\base\packages\SettingsProvider\res\values\defaults.xml
<integer name="def_wifi_sleep_policy">0</integer>
<!-- 0 == Never, 1 == Only when plugged in,2 == Always. -->
14. Launcher 半透明
4.0， 4.1 下載附件中的patch集合---translucent.zip
如果是 4.2.2系統，還需修改
Launcher/src/com/android/launcher2/Launcher.java
mLauncherView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
mWorkspaceBackgroundDrawable = getResources().getDrawable(R.drawable.workspace_bg);
mBlackBackgroundDrawable = new ColorDrawable(Color.BLACK); // 修改為 mBlackBackgroundDrawable = new ColorDrawable(0x7f000000);
packages\amlogic\Launcher2\src\com\android\launcher2\Launcher.java
mStateAnimation.addListener(new AnimatorListenerAdapter() {
boolean animationCancelled = false;
@Override
public void onAnimationStart(Animator animation) {
dispatchOnLauncherTransitionEnd(fromView, animated, false); //add
dispatchOnLauncherTransitionEnd(toView, animated, false); //add
updateWallpaperVisibility(false); //true 改成false
// Prepare the position
toView.setTranslationX(0.0f);
toView.setTranslationY(0.0f);
toView.setVisibility(View.VISIBLE);
toView.bringToFront();
}
15. APK 預裝時無法找到lib庫的問題
(1) 如果log報錯是找不到lib庫首先可以修改lib的路徑
jb4.1\frameworks\base\core\java\android\app\NativeActivity.java
public static final String SYSTEM_LIB_PATH = "/system/lib";
if (libraryFile.exists()) {
path = libraryFile.getPath();
}else{
File systemLibraryFile = new File(SYSTEM_LIB_PATH,System.mapLibraryName(libname));
if (systemLibraryFile.exists()) {
path = systemLibraryFile.getPath();
}
}
(2)apk本身會檢測檢測/data/data/lib路徑是否存在資原始檔時方法1不適用，用第二種方法：
在專案上的mk檔案 /device/amlogic/g18refg/8ref.mk 中,加上preinstallation
PRODUCT_PACKAGES += \
lights.amlogic \
FileBrowser \
AppInstaller \
VideoPlayer \
HdmiSwitch \
Update \
fw_env \
preinstallation
將網頁底部的附件 Preinstallation.zip拷貝到packages\amlogic下面解壓 將需要預裝安裝的apk拷貝到preinstallation目錄下面，編輯裡面的preinstall.sh檔案內容如下：
#!/system/xbin/busybox sh
echo "do preinstall applications"
# com.mxtech.videoplayer.ad apk包名
if [ ! -e /data/data/com.mxtech.videoplayer.ad/ ]; then
pm install /system/preinstall/com.mxtech.videoplayer.ad.50.apk
fi
if [ ! -e /data/data/org.xbmc.xbmc/ ]; then
pm install /system/preinstall/xbmc-20130414-e2c3799-Frodo-armeabi-v7a.apk
fi
。。。。。。
然後在device\amlogic\common\init\tablet\init.amlogic.rc 中,啟動預安裝指令碼的服務.
MX:
service preinstall /system/bin/preinstall.sh
class main
user root
group root
oneshot
console
disabled
M3:
service preinstall /system/bin/preinstall.sh
user root
group root
disabled
oneshot
在init.amlogic.rc最後一行加上
start preinstall
把紅色的部分刪掉
device\amlogic\gXXXX\overlay\frameworks\base\core\res\res\values\config.xml
<string-array translatable="false" name="config_tether_wifi_regexs">
<item>"wlap0"</item>

android:contentDescription="@string/accessibility_switch_to_panorama"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:visibility="gone"
android:scaleType="center"
android:background="@drawable/bg_pressed"
android:src="@drawable/ic_switch_pan_holo_light" />
4.2：
<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>
加上紅色加亮的地方：
public void init() {
for (int i = 0; i < mDrawables.length; i++) {
if ((i == LIGHTCYCLE_MODULE_INDEX && !LightCycleHelper.hasLightCycleCapture(this))||i == PANORAMA_MODULE_INDEX) {
continue; // not enabled, so don't add to UI
}
drawids[ix++] = DRAW_IDS[i];
}
<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>
public void init() {
int[] drawids = new int[LightCycleHelper.hasLightCycleCapture(this)
? DRAW_IDS.length -1 : DRAW_IDS.length - 2];
<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_status_land.xml>
<TextView android:id="@+id/timeDisplayBackground"
android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"
<TextView android:id="@+id/timeDisplayForeground"
android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"
//dimens.xml裡的keyguard_pattern_unlock_clock_font_size調小
可以把clock調成居中顯示，不要靠右，造成右邊顯示不全
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right">
//改成center
加上紅色語句：
<\packages\apps\Settings\src\com\android\settings\fuelgauge\BatteryHistoryChart.java>
if (!com.android.settings.Utils.isWifiOnly(getContext())) {
mHavePhoneSignal = true;
}
mHavePhoneSignal = false;
把自己專案overlay中的
frameworks/base/core/res/res/values/config.xml
<bool name="config_animateScreenLights">false</bool> 刪掉 就可以了
22. 新增格式化內部sdcard
jb4.1\packages\amlogic\Settings\src\com\android\settings\deviceinfo\StorageVolumePreferenceCategory.java
public StorageVolumePreferenceCategory(Context context, Resources resources, StorageVolume storageVolume, StorageManager storageManager, boolean isPrimary) {
// Cannot format emulated storage
mAllowFormat = mStorageVolume != null && !mStorageVolume.isEmulated()&&mStorageVolume.isRemovable();
// For now we are disabling reformatting secondary external storage
// until some interoperability problems with MTP are fixed
//if (!isPrimary) mAllowFormat = false;
+ if(mStorageVolume != null && mStorageVolume.getPath().equals("/storage/sdcard0")){
+ mAllowFormat = true;
+ }
4.2 Lockscreen 對應的java 檔案不再是 Lockscreen, 而是KeyguardSelectorView.java
frameworks/base/core/res/res/values/arrays.xml b/core/res/res/values/arrays.xml
<array name="lockscreen_targets_unlock_only">
<item>@*android:drawable/ic_lockscreen_unlock</item>
+ <item>@null</item>
+ <item>@null</item>
+ <item>@null</item>
</array>
<array name="lockscreen_target_descriptions_unlock_only">
<item>@*android:string/description_target_unlock</item>
+ <item>@null</item>
+ <item>@null</item>
+ <item>@null</item>
</array>
24.android 4.2改launcher裡面的icon橫排的數目：
<\packages\apps\Launcher2\res\values-sw720dp\config.xml>
<integer name="cell_count_x">7</integer>
如果改成7，hotseat裡面第8個icon不見了，可以往第8個槽裡面放進去，但是重啟後，icon又不見了，可以這樣修改：
<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>
final ItemInfo occupied[][][] =
new ItemInfo[Launcher.SCREEN_COUNT + 1][mCellCountX + 2][mCellCountY + 1]; //原來這裡是+1
frameworks\base\core\res\res\values/arrays.xml
<array name="lockscreen_targets_with_camera">
<item>@drawable/ic_lockscreen_unlock</item>
<item>@drawable/ic_action_assist_generic</item>
<item>@drawable/ic_lockscreen_camera</item>
<item>@drawable/ic_lockscreen_settings</item>
</array>
在 frameworks\base\core\res\res\drawable 增加 ic_lockscreen_settings.xml 檔案 並新增 ic_lockscreen_settings_normal.phg ic_lockscreen_settings_activated.png 資原始檔
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="true"
android:state_active="false"
android:state_focused="false"
android:drawable="@drawable/ic_lockscreen_settings_normal" />
<item
android:state_enabled="true"
android:state_active="true"
android:state_focused="false"
android:drawable="@drawable/ic_lockscreen_settings_activated" />
<item
android:state_enabled="true"
android:state_active="false"
android:state_focused="true"
android:drawable="@drawable/ic_lockscreen_settings_activated" />
</selector>
frameworks\base\policy\src\com\android\internal\policy\impl\LockScreen.java
public void onTrigger(View v, int target) {
final int resId = mGlowPadView.getResourceIdForTarget(target);
switch (resId) {
case com.android.internal.R.drawable.ic_lockscreen_settings: //啟動setting 應用
launchActivity(new Intent().setComponent(new ComponentName("com.android.settings","com.android.settings.Settings")));
mCallback.pokeWakelock();
break;
去掉專案overlay/frameworks/base/core/res/res/config.xml 中的config_enableWifiDisplay
27. 預設音量修改
frameworks/base/media/java/android/media/AudioService.java
private final int[] MAX_STREAM_VOLUME = new int[] {
5, // STREAM_VOICE_CALL
7, // STREAM_SYSTEM
7, // STREAM_RING
15, // STREAM_MUSIC
7, // STREAM_ALARM
7, // STREAM_NOTIFICATION
15, // STREAM_BLUETOOTH_SCO
7, // STREAM_SYSTEM_ENFORCED
15, // STREAM_DTMF
15 // STREAM_TTS
};
frameworks/base/media/java/android/media/AudioManager.java
/** @hide Default volume index values for audio streams */
public static final int[] DEFAULT_STREAM_VOLUME = new int[] {
4, // STREAM_VOICE_CALL
7, // STREAM_SYSTEM
5, // STREAM_RING
11, // STREAM_MUSIC
6, // STREAM_ALARM
5, // STREAM_NOTIFICATION
7, // STREAM_BLUETOOTH_SCO
7, // STREAM_SYSTEM_ENFORCED
11, // STREAM_DTMF
11 // STREAM_TTS
};
<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>
updatePackages裡面新增：
if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){
mWidgets.add(widget);
}
29.去掉設定-->顯示-->亮度裡的“自動調整亮度”選項
<\packages\apps\Settings\res\layout\preference_dialog_brightness.xml>
<CheckBox android:id="@+id/automatic_mode"
加上
android:visibility="invisible"
<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>
<string name="def_location_providers_allowed" translatable="false"></string>
這裡不要填寫gps或者network，清空
31.設定-安全-驗證應用預設不勾允
<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>
<boolname="def_package_verifier_enable">false</bool>32.設定-聲音-觸控提示音與鎖屏提示音預設不勾允狀態
<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>
<integer name="def_lockscreen_sounds_enabled">0</integer>
<boolname="def_sound_effects_enabled">false</bool>33.設定-乙太網選單請移動“更多”選單下
請用附件ethernet.patch，開關是ro.ethernet.more，設定為true，ethernet移到more裡面
在settings的git下打這個patch
34.視窗小部件“指標時鐘”顯示不全
把clock的widget向上調，下面的值改小：
<\packages\amlogic\Launcher2\res\values\dimens.xml>
<dimenname="app_widget_preview_padding_top">10dp</dimen>35.去掉settings的more裡面的網路共享與行動式熱點
ro.tether.denied=true
36.平臺主介面底部工具欄上的圖示全部居中顯示，從左至右的圖示依次為：vol-、back、home、視窗切換、vol+
1.在prop裡面將ro.statusbar.volume設定為true
2.<\frameworks\base\packages\SystemUI\res\layout-sw600dp\navigation_bar.xml>
將
<com.android.systemui.statusbar.policy.KeyButtonViewandroid:id="@+id/sub"
……
/>
這段放到
<com.android.systemui.statusbar.policy.KeyButtonViewandroid:id="@+id/back"
……
/>
這段之前
<com.android.systemui.statusbar.policy.KeyButtonViewandroid:id="@+id/add"
……
/>
這段放到
<com.android.systemui.statusbar.policy.KeyButtonView
android:id="@+id/recent_apps"
……
/>
這段之後注意這個檔案有兩處需要調換上面的
37.主介面模擬時鐘改成數字時鐘
default_workspace.xml裡面加上：
<appwidget
launcher:packageName="com.android.deskclock"
launcher:className="com.android.alarmclock.DigitalAppWidgetProvider"38、settings中的developeroptions的開關開啟，debug關掉：
<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>
private void loadSecureSettings(SQLiteDatabase db) {
loadSetting(stmt,Settings.Secure.ADB_ENABLED, 0);
loadSetting(stmt,Settings.Secure.DEVELOPMENT_SETTINGS_ENABLED, 1);39、改桌面icon行、列數：
<\packages\apps\Launcher2\res\layout-sw***dp\workspace.xml>
launcher:cellCountX="10"
launcher:cellCountY="6"40、more裡面morebile data項預設不選：
1.<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>
private void loadSecureSettings(SQLiteDatabase db) {
SQLiteStatement stmt = null;
try {
stmt = db.compileStatement("INSERT OR IGNOREINTO secure(name,value)"
+ "VALUES(?,?);");
新增：
loadIntegerSetting(stmt,Settings.Secure.MOBILE_DATA,
R.integer.def_mobile_data);
2.<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>
<integername="def_mobile_data">0</integer>41.secure的unknown的設定預設開啟：
<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<com.android.launcher2.AppsCustomizeTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:launcher="http://schemas.android.com/apk/res/c...droid.launcher"
android:background="@drawable/wallpaper_03">43、bluetoothtethering的checkbox去掉：
overlay裡面的
<\frameworks\base\core\res\res\values\config.xml>
<string-array translatable="false" name="config_tether_bluetooth_regexs">
<item>"bt-pan"</item>
</string-array>
去掉<item>"bt-pan"</item>44. Googleplay 不是內建，而是安裝，導致出問題的解決辦法
frameworks/baseservices/java/com/android/server/pm/PackageManagerService.java
@@ -4594,6+4594,9 @@ public class PackageManagerService extends IPackageManager.Stub {

if (!allowed&& (bp.protectionLevel
& PermissionInfo.PROTECTION_FLAG_DEVELOPMENT) != 0) {
//For development permissions, a development permission
45.乙太網設定問題
乙太網在settings.db中的條目是"eth_on",預設值由系統屬性ro.ethernet.default_on 決定，
ro.ethernet.default_on=false預設關閉
ro.ethernet.default_on=true預設開啟
不定義該屬性預設關閉
