android 下 安卓一樣的兩個app

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.my.app" android:versionCode="1" android:versionName="1.0" >

app/build.gradle: apply plugin: 'com.android.application'

android { compileSdkVersion 19 buildToolsVersion "19.1"

defaultConfig {
    applicationId "com.example.my.app"
    minSdkVersion 15
    targetSdkVersion 19
    versionCode 1
    versionName "1.0"
}
...

(In Android Studio you can configure all of this graphically as well in the Project Structure dialog.)
