[Keyword]

App Persistent persistent

[Solution]

1. Add an attribute android:persistent= "true" to application in the app's manifest.xml

2. Use platform's signature for this app

3. Place under System/app

Note: After an app is set to persistent, it will be difficult to kill by low memory Kill (OOM_ADJ=-12), please carefully confirm whether it is necessary before setting, otherwise it will waste memory.
