Is PackageManager.getComponentEnabledSettings() persistent between cold starts?

问题

If I use the code below to disable a static BroadcastReceiver defined in AndroidManifest.xml, will it be re-enabled after a reboot? It doesn't appear to be but the docs don't say whether it should.

final ComponentName compName =
        new ComponentName(context,
        MyBroadcastReceiver.class);

context.getPackageManager().setComponentEnabledSetting(
        compName,
        PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
        PackageManager.DONT_KILL_APP);

Thanks in advance...

Yes. It will be reset on an application uninstall/reinstall. It will be reset if you reset it yourself with setComponentEnabledSetting(). It'll be reset if something with superuser privileges resets it (e.g., the device might have some manager app for controlling ACTION_BOOT_COMPLETED). And I'm not sure what happens on an app upgrade, as I haven't tried that scenario. Otherwise, it should stay persistent.

No.
