Android 共存debug release版, 并设置不同名字

一部手机上同时安装app的debug版和release版，并显示不同名字

build.gradle

buildTypes {
         debug {
            applicationIdSuffix ".debug"
            resValue "string", "app_name", "@string/app_name_debug"
        }
        release {
            applicationIdSuffix ".release"
            resValue "string", "app_name", "@string/app_name_release"
        }
}
       

strings.xml

<resources>
    <string name="app_name_debug">Debug</string>
    <string name="app_name_release">Release</string>
</resources>

AndroidManifest.xml

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
 </application>

debug release版使用不同的ic_launcher 
在src下面创建debug-res-mipmap-xx, 放入对应的ic_launcher.png
