Android disable third-party apps

Permission required android.Manifest.permission.CHANGE_COMPONENT_ENABLED_STATE

And this permission can only be used by system app, so app needs system signature. Even if the non-system app is forced to be written in Android Mainfest.xml, it will also be written to /data/system/packages.xml during installation

Enable third-party app icons:

PackageManager pm = getPackageManager();  
                pm.setApplicationEnabledSetting(packageName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED_USER, 0);  

Disable third-party icons:

PackageManager pm = getPackageManager();  
                pm.setApplicationEnabledSetting(packageName, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT, 0);  

If the app is disabled, the icon disappears from the desktop, otherwise, if enabled, the icon is displayed
