我想在我正在工作的 Android 应用程序中显示本地通知。通知基于在后台完成的网络事务。
我已经尝试过服务、意图服务、工作服务等,但是当应用程序关闭时没有任何工作。请分享一些工作代码以供参考.....
//这是我的服务----
public class JobSyncFAQ extends Service {
private Message msg;
private Looper mServiceLooper;
private ServiceHandler mServiceHandler;
public JobSyncFAQ() {
}
private final class ServiceHandler extends Handler {
public ServiceHandler(Looper looper) {
super(looper);
}
@Override
public void handleMessage(Message msg) {
// here is my stuff
stopSelf(msg.arg1);
}
}
public void onCreate() {
super.onCreate();
HandlerThread thread = new HandlerThread("JobSyncFAQ", Process.THREAD_PRIORITY_BACKGROUND);
thread.start();
mServiceLooper = thread.getLooper();
mServiceHandler = new ServiceHandler(mServiceLooper);
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
msg = mServiceHandler.obtainMessage();
msg.arg1 = startId;
mServiceHandler.sendMessage(msg);
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
mServiceHandler.removeCallbacks(mServiceLooper.getThread());
mServiceLooper.quit();
Intent intent = new Intent(getApplicationContext(),JobSyncFAQ.class);
sendBroadcast(intent);
}
//and in my receiver
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context, JobSyncFAQ.class));
}
请注意 - 我只在 N+ 版本中遇到这个问题
