测试机器环境如下：
Meizu Mx4 - Android 5.1 - Flyme 5.1.11.1A
First prepare your new app icons for each resolution and put them into the corresponding mipmap folders.
Then use activity-alias, for example, in your AndroidManifest.xml, edit this:

<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity-alias
android:name=".MainAliasActivity"
android:enabled="false"
android:icon="@mipmap/ic_launcher_fight"
android:label="Main Alias Activity"
android:targetActivity=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
