【環境配置】配置AndroidStudio

1. 構建新專案，gradle下載不成功的問題。
建立新專案的時候，提示一直下載gradle，但是無法下載成功。
(1) 去gradle的官網下載壓縮包。
(2) 把下載好的gradle-1.12-all.zip拷貝到~/.gradle/wrapper/dists/gradle-1.12-all/2apkk7d25miauqf1pdjp1bm0uo
注：如果用AS建立過新的工程，那麼AS會自動建立這個目錄。
(3) 重新開啟Android Studio，等待AS自動完成gradle的配置。
下面是終端裡面Android Studio的工作日誌，可以看出，首先Android Studio會解壓gradle-1.12-all.zip，然後下載一些依賴的jar。
Unzipping /home/kaizen/.gradle/wrapper/dists/gradle-1.12-all/2apkk7d25miauqf1pdjp1bm0uo/gradle-1.12-all.zip to /home/kaizen/.gradle/wrapper/dists/gradle-1.12-all/2apkk7d25miauqf1pdjp1bm0uo

2. 使用gradle編譯安裝apk，出現INSTALL_PARSE_FAILED_UNEXPECTED_EXCEPTION 的問題。
在AndroidManifest.xml中配置<uses-sdk/>標籤：
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />但是，build.gradle檔案中是這樣配置的。
apply plugin: 'com.android.application'
android {
compileSdkVersion 19
buildToolsVersion "19.1.0"
defaultConfig {
applicationId "com.example.kaizen.myapplication"
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
}
修改minSdkVersion 8，重新編譯安裝成功，不再報錯。
3. 配置程式碼的背景色，保護視力。
設定background的色值為(199, 237, 204)，然後點選Apply按鈕，使配置生效。
