Android Studio improt project APIDemo

1.  File -> Import project -> path  [D:\Android_SDK\samples\android-23\legacy\ApiDemos]

2.  app\src\main\res\xml\preference_switch改成preference_switch.xml

3. Modify app's gradle.build 

repositories{
    flatDir{
        dirs 'libs'
        dirs 'aars'
    }
}

repositories{
    flatDir{
        dirs 'libs'
        dirs 'aars'
    }
}
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.example.android.apis"

        testApplicationId "com.example.android.test.apis" // 原来名字重复
        testInstrumentationRunner ".app.LocalSampleInstrumentation"
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

 Modify dependence 

    dependencies {
    	compile fileTree(include: ['*.jar'], dir: 'libs')
    	compile 'com.android.support:support-v4:23.4.0'
    	compile 'com.android.support:appcompat-v7:23.4.0'
    	compile files('libs/android-src.jar') //需要另外单独下载，见附件
	}

4. com.google.android mms 不存在系列问题 直接删除OS 目录下两个文件 MmsMessagingDemo.java MmsWcipPushReceiver.java
