应用程序上的广播接收器关闭（或在后台） [英] Broadcast receiver on app closed (or in the background)

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.
