Android 5.0(Lollipop)服务意图必须是明确的

Question

我正在开发一个小部件,代码在前Lollipop设备上工作正常但是当我在Lollipop上运行我的代码时,它给了我错误Service Intent must be explicit: Intent { act=org.clangen.widget.clock.action.UPDATE }.我有谷歌这个错误,但我不明白甚至这个[问题] Android 5.0(L)服务意图必须明确在谷歌分析.这是logcat

这是带有内部服务的widget类

public class ClockWidget extends AppWidgetProvider {

    private static final String SHOW_POPUP_DIALOG_ACTION = "com.brainlogix.widget.Widget_PopUp";

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
            int[] appWidgetIds) {
        super.onUpdate(context, appWidgetManager, appWidgetIds);

        context.startService(new Intent(UpdateService.ACTION_UPDATE));
    }

    public static final class UpdateService extends Service {       
        static final String ACTION_UPDATE = "org.clangen.widget.clock.action.UPDATE";           
        @Override
        public void onCreate() {
            super.onCreate();
            registerReceiver(mTimeChangedReceiver, sIntentFilter);
        }

        @Override
        public void onDestroy() {
            super.onDestroy();
            unregisterReceiver(mTimeChangedReceiver);
        }

        @Override
        public void onStart(Intent intent, int startId) {
            super.onStart(intent, startId);
        }

        @Override
        public IBinder onBind(Intent intent) {
            return null;
        }       
        private void update() {
        //some code
        }   
        private final BroadcastReceiver mTimeChangedReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                final String action = intent.getAction();

                if (action.equals(Intent.ACTION_TIME_CHANGED)
                        || action.equals(Intent.ACTION_TIMEZONE_CHANGED)) {
                    // some code
                }
                update();
            }
        };
    }
}

仅使用操作实例化Intent会创建所谓的隐式Intent,因为为了执行此操作,将启动为处理该操作而注册的任何组件.从Lollipop开始,由于安全问题,服务无法再以隐式Intent启动.您只需要具体了解Intent的用途; 即,使用显式的意图.

context.startService(new Intent(context, UpdateService.class));

您还应该<intent-filter>从清单中的服务中删除该元素,因为这是允许使用隐式Intent启动服务的,这是不再允许的.
