public class UpdataService extends Service { public UpdataService() { } /** * 安卓系統下載類 **/ private DownloadManager manager; /** * 接收下載完的廣播 **/ private DownloadCompleteReceiver receiver; private String url; private String DOWNLOADPATH = "/download/";//下載路徑，如果不定義自己的路徑，6.0的手機不自動安裝 /** * 初始化下載器 **/ private void initDownManager() { manager = (DownloadManager) getSystemService(DOWNLOAD_SERVICE); receiver = new DownloadCompleteReceiver(); //設定下載地址 DownloadManager.Request down = new DownloadManager.Request(Uri.parse(url)); // 設定允許使用的網路型別，這裡是行動網路和wifi都可以 down.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE | DownloadManager.Request.NETWORK_WIFI); down.setAllowedOverRoaming(false); MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton(); String mimeString = mimeTypeMap.getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(url)); down.setMimeType(mimeString); // 下載時，通知欄顯示途中 down.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE); // 顯示下載介面 down.setVisibleInDownloadsUi(true); // 設定下載後文件存放的位置 down.setDestinationInExternalPublicDir(DOWNLOADPATH, "app-release.apk"); down.setTitle("****"); // 將下載請求放入佇列 manager.enqueue(down); //註冊下載廣播 registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE)); } @Overrid public int onStartCommand(Intent intent, int flags, int startId) { url = intent.getStringExtra("downloadurl"); String path = Environment.getExternalStorageDirectory().getAbsolutePath() + DOWNLOADPATH + "app-release.apk"; File file = new File(path); if (file.exists()) { file.delete(); } try { // 呼叫下載 initDownManager(); } catch (Exception e) { e.printStackTrace(); Toast.makeText(getApplicationContext(), "下載失敗", Toast.LENGTH_SHORT).show(); } return Service.START_NOT_STICKY; } @Override public IBinder onBind(Intent intent) { return null; } @Override public void onDestroy() { if (receiver != null) // 登出下載廣播 unregisterReceiver(receiver); super.onDestroy(); } // 接受下載完成後的intent class DownloadCompleteReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { //判斷是否下載完成的廣播 if (intent.getAction().equals(DownloadManager.ACTION_DOWNLOAD_COMPLETE)) { //獲取下載的檔案id long downId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1); if (manager.getUriForDownloadedFile(downId) != null) { //自動安裝apk installAPK(manager.getUriForDownloadedFile(downId), context); //installAPK(context); } else { Toast.makeText(context, "下載失敗", Toast.LENGTH_SHORT).show(); } //停止服務並關閉廣播 UpdataService.this.stopSelf(); } } private void installAPK(Uri apk, Context context) { if (Build.VERSION.SDK_INT < 23) { Intent intents = new Intent(); intents.setAction(Intent.ACTION_VIEW); // intents.addCategory("android.intent.category.DEFAULT"); intents.setDataAndType(apk, "application/vnd.android.package-archive"); intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intents); } else if (Build.VERSION.SDK_INT >= 24) { install(context); } else { File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + DOWNLOADPATH + "app-release.apk"); if (file.exists()) { openFile(file, context); } else { } } } /** * android7.0之後的更新 * 通過隱式意圖呼叫系統安裝程式安裝APK */ public void install(Context context) { File file = new File( Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) , "app-release.apk"); Intent intent = new Intent(Intent.ACTION_VIEW); //引數1 上下文, 引數2 Provider主機地址 和配置檔案中保持一致 引數3 共享的檔案 Uri apkUri = FileProvider.getUriForFile(context, "cn.jiandao.global.fileprovider", file); intent.addCategory("android.intent.category.DEFAULT"); // 由於沒有在Activity環境下啟動Activity,設定下面的標籤 intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //新增這一句表示對目標應用臨時授權該Uri所代表的檔案 intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); intent.setDataAndType(apkUri, "application/vnd.android.package-archive"); context.startActivity(intent); } private void installAPK(Context context) { File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + DOWNLOADPATH + "huijuquanqiu.apk"); if (file.exists()) { openFile(file, context); } else { Toast.makeText(context, "下載失敗", Toast.LENGTH_SHORT).show(); } } } /** * android6.0之後的升級更新 * * @param file * @param context */ public void openFile(File file, Context context) { Intent intent = new Intent(); intent.addFlags(268435456); intent.setAction("android.intent.action.VIEW"); String type = getMIMEType(file); intent.setDataAndType(Uri.fromFile(file), type); try { context.startActivity(intent); } catch (Exception var5) { var5.printStackTrace(); Toast.makeText(context, "沒有找到開啟此類檔案的程式", Toast.LENGTH_SHORT).show(); } } public String getMIMEType(File var0) { String var1 = ""; String var2 = var0.getName(); String var3 = var2.substring(var2.lastIndexOf(".") + 1, var2.length()).toLowerCase(); var1 = MimeTypeMap.getSingleton().getMimeTypeFromExtension(var3); return var1; } }
3.這是後臺下載app，並且安裝的後臺服務
（1）開啟服務，初始化下載地址
@Override public int onStartCommand(Intent intent, int flags, int startId) { url = intent.getStringExtra("downloadurl"); String path = Environment.getExternalStorageDirectory().getAbsolutePath() + DOWNLOADPATH + "app-release.apk"; File file = new File(path); if (file.exists()) { file.delete(); } try { // 呼叫下載 initDownManager(); } catch (Exception e) { e.printStackTrace(); Toast.makeText(getApplicationContext(), "下載失敗", Toast.LENGTH_SHORT).show(); } return Service.START_NOT_STICKY; }
（2）初始化下載方法，並且在通知欄設定下載進度條，並且註冊廣播接收者
/** * 初始化下載器 **/ private void initDownManager() { manager = (DownloadManager) getSystemService(DOWNLOAD_SERVICE); receiver = new DownloadCompleteReceiver(); //設定下載地址 DownloadManager.Request down = new DownloadManager.Request(Uri.parse(url)); // 設定允許使用的網路型別，這裡是行動網路和wifi都可以 down.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE | DownloadManager.Request.NETWORK_WIFI); down.setAllowedOverRoaming(false); MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton(); String mimeString = mimeTypeMap.getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(url)); down.setMimeType(mimeString); // 下載時，通知欄顯示途中 down.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE); // 顯示下載介面 down.setVisibleInDownloadsUi(true); // 設定下載後文件存放的位置 down.setDestinationInExternalPublicDir(DOWNLOADPATH, "app-release.apk"); down.setTitle("****"); // 將下載請求放入佇列 manager.enqueue(down); //註冊下載廣播 registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE)); }
（3）啟動廣播接收者，並開啟自動安裝app
// 接受下載完成後的intent
class DownloadCompleteReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
//判斷是否下載完成的廣播
if (intent.getAction().equals(DownloadManager.ACTION_DOWNLOAD_COMPLETE)) {
//獲取下載的檔案id
long downId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
if (manager.getUriForDownloadedFile(downId) != null) {
//自動安裝apk
installAPK(manager.getUriForDownloadedFile(downId), context);
//installAPK(context);
} else {
Toast.makeText(context, "下載失敗", Toast.LENGTH_SHORT).show();
}
//停止服務並關閉廣播
UpdataService.this.stopSelf();
}
}
private void installAPK(Uri apk, Context context) {
if (Build.VERSION.SDK_INT < 23) {
Intent intents = new Intent();
intents.setAction(Intent.ACTION_VIEW);
// intents.addCategory("android.intent.category.DEFAULT");
intents.setDataAndType(apk, "application/vnd.android.package-archive");
intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intents);
} else if (Build.VERSION.SDK_INT >= 24) {
install(context);
} else {
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + DOWNLOADPATH + "app-release.apk");
if (file.exists()) {
openFile(file, context);
} else {
}
}
}
/**
* android7.0之後的更新
* 通過隱式意圖呼叫系統安裝程式安裝APK
*/
public void install(Context context) {
File file = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
, "app-release.apk");
Intent intent = new Intent(Intent.ACTION_VIEW);
//引數1 上下文, 引數2 Provider主機地址 和配置檔案中保持一致 引數3 共享的檔案
Uri apkUri =
FileProvider.getUriForFile(context, "cn.jiandao.global.fileprovider", file);
intent.addCategory("android.intent.category.DEFAULT");
// 由於沒有在Activity環境下啟動Activity,設定下面的標籤
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//新增這一句表示對目標應用臨時授權該Uri所代表的檔案
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
context.startActivity(intent);
}
private void installAPK(Context context) {
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + DOWNLOADPATH + "huijuquanqiu.apk");
if (file.exists()) {
openFile(file, context);
} else {
Toast.makeText(context, "下載失敗", Toast.LENGTH_SHORT).show();
}
}
}（4）android6.0之後的安裝
/**
* android6.0之後的升級更新
*
* @param file
* @param context
*/
public void openFile(File file, Context context) {
Intent intent = new Intent();
intent.addFlags(268435456);
intent.setAction("android.intent.action.VIEW");
String type = getMIMEType(file);
intent.setDataAndType(Uri.fromFile(file), type);
try {
context.startActivity(intent);
} catch (Exception var5) {
var5.printStackTrace();
Toast.makeText(context, "沒有找到開啟此類檔案的程式", Toast.LENGTH_SHORT).show();
}
}
public String getMIMEType(File var0) {
String var1 = "";
String var2 = var0.getName();
String var3 = var2.substring(var2.lastIndexOf(".") + 1, var2.length()).toLowerCase();
var1 = MimeTypeMap.getSingleton().getMimeTypeFromExtension(var3);
return var1;
}（5）主要是android 7.0的配置，android7.0之後的安裝
/**
* android7.0之後的更新
* 通過隱式意圖呼叫系統安裝程式安裝APK
*/
public void install(Context context) {
File file = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
, "app-release.apk");
Intent intent = new Intent(Intent.ACTION_VIEW);
//引數1 上下文, 引數2 Provider主機地址 和配置檔案中保持一致 引數3 共享的檔案
Uri apkUri =
FileProvider.getUriForFile(context, "cn.xxx.xxx.fileprovider", file);
intent.addCategory("android.intent.category.DEFAULT");
// 由於沒有在Activity環境下啟動Activity,設定下面的標籤
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//新增這一句表示對目標應用臨時授權該Uri所代表的檔案
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
context.startActivity(intent);
