我正在开发一个小部件，代码在Lollipop之前的设备上正常工作但是当我在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，但我甚至不理解[问题] Android 5.0 (L) Service Intent must be explicit in Google analytics。
这是logcat

这是具有内部服务的小部件类
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();
}
};
}
}

答案 0 :(得分：5)
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;即使用明确的意图。
context.startService(new Intent(context, UpdateService.class));
您还应该从清单中的服务中删除<intent-filter>元素，因为这样就可以使用隐式Intent启动您的服务，这是不再允许的。
