应用程序上的广播接收器关闭（或在后台）

本文介绍了应用程序上的广播接收器关闭（或在后台）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我创建了一个简单的警报应用，我在 AndroidManifest.xml 中注册了两个广播接收器（一个用于接收警报和其他警报，以便在设备启动时重新安排它们）。安排了一些警报后，我重新启动了设备，我的 OnBoot接收器重新安排了警报，但是第一个接收器无法接收到警报。如果我启动我的应用程序，安排一些警报并且不关闭它，则接收器将正常工作，但是如果我关闭（而不是强制停止）应用程序或通过按主按钮将其发送到后台，接收方将永远不会收到警报！我在几种设备（HTC，魅族，三星）上进行了测试，但遇到了同样的问题。我发现使接收器正常工作的唯一方法是杀死应用程序，因为再次启动它后，即使应用程序已关闭，接收器也能正常工作，但是再次重启设备后，我也会遇到同样的问题。拜托，有人可以帮我吗？我需要做些什么来摆脱这个问题？

I create a simple alarms app and I have two broadcast receivers registered in AndroidManifest.xml (One for receiving alarms and other for rescheduling them on device boot). After scheduling some alarms I reboot my device and my "OnBoot" receiver rescheduling alarms well, but the first receiver doesn't recive them. If I start my app, schedule some alarms and won't close it, the receiver will work fine, but if I close (not force stop) app or send it into background by pressing the home button, receiver will never receive alarms! I tested it on several devices (HTC, Meizu, Samsung) and got same problem. There is only one way I found to make the receiver work normally is to kill app, because after I start it again, the receiver is working normally even app is closed, but after I reboot device again I will get same problem. Please, can anyone help me with that? What I need to do to get rid of this problem?

我几乎尝试了所有操作（更改 pendingintent标志和请求代码，正在运行的接收器在远程进程中，设置意图过滤器，扩展（来自 WakefulBroadcastReceiver 等），但没有任何帮助。

I tried almost everything(changing pendingintent flags and request codes, running receivers in remote processes, setting an intent-filters, extend from WakefulBroadcastReceiver and many other) but nothing has helped me.

AndroidManifest.xml中的接收器

<receiver android:name="com.gd.aiwnext.deal.Receivers.NotificationsReceiver" android:enabled="true" android:exported="true" android:process=":nr"> <intent-filter> <action android:name="com.gd.action.intent.bri"></action> </intent-filter> </receiver> <receiver android:name="com.gd.aiwnext.deal.Receivers.NotificationBootReceiver" android:process=":nbr"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <category android:name="android.intent.category.DEFAULT" /> <action android:name="android.intent.action.QUICKBOOT_POWERON" /> </intent-filter> </receiver>

BroadcastReceiver

public class NotificationsReceiver extends WakefulBroadcastReceiver { SQLiteDatabase NoteDataBase; NotesDataBase notesDataBase; String OLDDATE, NEWDATE, INTPICKER, OLDTIME, NEWTIME; String NewYear, NewMonth, NewDay, NewHour, NewMinute; long CurrentTimeInMillis, FutureTimeInMillis; Boolean StartAfterSleep; String FinalHour = "", FinalMinute = "", FinalYear = "", FinalMonth = "", FinalDay = ""; boolean isDivided = false; @Override public void onReceive(Context context, Intent intent) { Log.d("BLL","Simple"); int id = intent.getIntExtra("id", 1); String note = intent.getStringExtra("note"); String interval = intent.getStringExtra("interval"); OLDDATE = intent.getStringExtra("date"); OLDTIME = intent.getStringExtra("time"); INTPICKER = intent.getStringExtra("intpicker"); CurrentTimeInMillis = intent.getLongExtra("timeinmillis", 0); if (intent.hasExtra("startaftersleep")) { StartAfterSleep = (intent.getBooleanExtra("startaftersleep", false)); } else { StartAfterSleep = false; } CreateNotification(id, note, interval, context); }

我使用CreateNotification（）方法发送通知和数据库以更新时间和日期

I use CreateNotification() method to send notifications and database to update time and date of alarm.

创建警报

Intent intent = new Intent("com.gd.action.intent.bri");

在那之后，我又放了一些东西，然后

After that I put some extra, and

PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), IdCount, intent, PendingIntent.FLAG_ONE_SHOT); alarmManager.setExact(AlarmManager.RTC_WAKEUP, FutureTimeMillis, pendingIntent);

推荐答案

您应该应用默认类别

<category android:name="android.intent.category.DEFAULT" />

如果未指定类别，则Android将该类别分配给每个意图。

Android assign this category to each intent if category isn't specified.
