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:

Add the following code when you want to change your app icon

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.
