亲测可以!
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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
| <activity android:name=".MainActivity"> <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"/> </intent-filter> </activity-alias>

Add the following code when you want to change your app icon
1 2 3 4 5 6 7 8 9
| PackageManager pm = getPackageManager(); pm.setComponentEnabledSetting( getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); pm.setComponentEnabledSetting( new ComponentName(this, "YOUR PACKAGE.MainAliasActivity"), PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

To reset the app icon you can use the same way.
