问题描述
我对 android 开发世界还很陌生，也很天真。我正在解决我们的 android 应用程序中的一个现有问题，到目前为止我还没有解决它。我很抱歉问了一个冗长的问题。
在当前用于跟踪店主是否开店或关店的应用中，我们显示了一个通知，用户可以点击该通知（当应用未在前台打开时）并从“值班”到“值班”。如果用户关闭了定位服务并且用户尝试点击从“Duty Off”到“Duty On”的通知，系统会尝试获取用户的纬度和经度，发出 POST 标注并打开应用程序主屏幕。当应用程序主屏幕打开时，用户看到应用程序无响应错误。这只发生在用户关闭他们的位置的情况下。
下面是我的代码片段，它是发生此操作时调用的类，它主要负责 2 个方法 createNotification 和 fun_DutyONOFF。自己在谷歌上搜索了很多，似乎如果 broadcastReceiver 在 10 秒内没有完成，Android 会抛出 Application Not Responding (ANR)。但我不确定这里的替代方案是什么，如果关闭定位服务，为什么会出现 ANR？任何帮助都可以挽救生命，因为我花了 3 天时间却没有运气。
public class SwitchButtonListenerON extends broadcastReceiver {
//Class variable declaration that I have omitted
@Override
public void onReceive(Context context,Intent intent) {
if ("dutyON".equalsIgnoreCase(intent.getAction())) {
SharedPrefrence_Login.getDataLogin(context);
location_update = new Location_Update(context);
createNotification(context);
//This is probably the method "fun_DutyONOFF" that takes more time but I am not sure how to replace the work done by this method
fun_DutyONOFF("1",SharedPrefrence_Login.getMhawker_code(),context);
}
}
private void createNotification(final Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mChannel = new NotificationChannel(CHANNEL_ID,"Hawker",notificationmanager.IMPORTANCE_HIGH);
}
Intent notificationIntent = new Intent(context,Home.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context,notificationIntent,0);
Intent dutyIntent = new Intent("action.cancel.notification");
PendingIntent pendingDutyIntent = PendingIntent.getbroadcast(context,dutyIntent,PendingIntent.FLAG_UPDATE_CURRENT);
RemoteViews notificationView = new RemoteViews(context.getPackageName(),R.layout.notification_layout);
//the intent that is started when the notification is clicked (works)
Notification notification = new NotificationCompat.Builder(context,CHANNEL_ID)
.setContentTitle("Location Service")
.setContentText("")
