android – 如何知道我的应用程序是否管理员

public class DeviceAdmin extends DeviceAdminReceiver {

    @Override
    public void onEnabled(Context context,Intent intent) {
        Log.i(this,"admin_receiver_status_enabled");
        // admin rights
        App.getPreferences().edit().putBoolean(App.ADMIN_ENABLED,truE).commit(); //App.getPreferences() returns the sharedPreferences

    }

    @Override
    public CharSequence onDisablerequested(Context context,Intent intent) {
        return "admin_receiver_status_disable_warning";
    }

    @Override
    public void onDisabled(Context context,Intent intent) {
        Log.info(this,"admin_receiver_status_disabled");
        // admin rights removed
        App.getPreferences().edit().putBoolean(App.ADMIN_ENABLED,falsE).commit(); //App.getPreferences() returns the sharedPreferences
    }
}

您应用中的任何位置：

DevicePolicymanager mDPM = (DevicePolicymanager)getSystemservice(Context.DEVICE_POLICY_serviCE);
ComponentName mAdminName = new ComponentName(this,DeviceAdmin.class); 

if(mDPM != null &&mDPm.isAdminActive(mAdminName)) {
    // admin active
}
