的BroadcastReceiver的onReceiver不叫，AlarmManager [英] onReceiver of BroadcastReceiver not called, AlarmManager

问题描述

我建立一个出租车预订应用程序，我需要每20秒的驾驶室当前位置。

我已经定义了一个AlarmManager并且需要它重演每20秒。但它不是经常重演。相反，它重演233秒后，并只有一次。我在做什么错在这里？

我的主屏幕上有一个内部类OnAlarmReceiver，在我的主屏幕我打电话AlarmManager的OnCreate

  AlarmManager经理=（AlarmManager）getSystemService（Context.ALARM_SERVICE）;
    意图I =新的意图（这一点，OnAlarmReceiver.class）;
    i.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
    PendingIntent PI = PendingIntent.getBroadcast（此，0，I，PendingIntent.FLAG_CANCEL_CURRENT）;
    日历CAL = Calendar.getInstance（）;
    cal.add（Calendar.SECOND，20）;
    mgr.setRepeating（AlarmManager.ELAPSED_REALTIME_WAKEUP，
            cal.getTimeInMillis（），God.UPDATE_PENDING_INTERVAL，PI）;
 

内部类中的主屏幕

  OnAlarmReceiver延伸的BroadcastReceiver {public类
    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        // PullPendingRequests.acquireStaticLock（上下文）;
        Toast.makeText（背景下，不要panik但你的时间到了!!!!，Toast.LENGTH_LONG）
                。显示（）;
        Log.d（Taxeeta：PullPendingRequets，CallService位置）;
        context.startService（新意图（背景下，PullPendingRequests.class））;
    }
}
 

我AndroidManifest文件有

 ＆LT;服务
        机器人：名称=com.taxeeta.support.PullPendingRequests
        机器人：启用=真
        机器人：标签=@字符串/ APP_NAME
        机器人：screenOrientation =画像
        机器人：主题=@安卓风格/ Theme.Light.NoTitleBar/＆GT;

    ＆LT;接收机器人：名称=。com.taxeeta.HomeScreen.OnAlarmReceiver/＆GT;
＆LT; /用途＆gt;
 

的亚行外壳dumpsys报警输出

  com.taxeeta
    51471ms运行，5248唤醒
    5248报警：FLG =为0x4 CMP = com.taxeeta / .HomeScreen $ OnAlarmReceiver
 

对亚行外壳dumpsys报警

输出| grep的taxeeta

  ELAPSED_WAKEUP＃7：报警{409303b0 2型com.taxeeta}
    操作= PendingIntent {408ba2d8：PendingIntentRecord {40887be8 com.taxeeta broadcastIntent}}
 com.taxeeta
    5248报警：FLG =为0x4 CMP = com.taxeeta / .HomeScreen $ OnAlarmReceiver
 

解决方案

要解决这个问题，我删除了内部类OnAlarmReceiver和固定AndroidManifest.xml文件。

 ＆LT;接收器
        机器人：名称=com.taxeeta.support.OnAlarmReceiver
        机器人：出口=真正的＆GT;
        ＆LT;意向滤光器＆gt;
            ＆lt;作用机器人：名称=android.intent.action.NOTIFY/＆GT;

I am building a cab booking app, I need current location of the cab every 20 seconds.

I have defined a AlarmManager and need it to repeat itself every 20 seconds. But its not repeating itself regularly. Instead it repeated itself after 233 seconds, and just once. What am I doing wrong here ?

My HomeScreen has a inner class OnAlarmReceiver, in the onCreate of my HomeScreen I am calling AlarmManager

    AlarmManager mgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent i = new Intent(this, OnAlarmReceiver.class);
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent pi = PendingIntent.getBroadcast(this, 0, i, PendingIntent.FLAG_CANCEL_CURRENT);
    Calendar cal = Calendar.getInstance();
    cal.add(Calendar.SECOND, 20);
    mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
            cal.getTimeInMillis(), God.UPDATE_PENDING_INTERVAL, pi);

Inner class in HomeScreen

public class OnAlarmReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // PullPendingRequests.acquireStaticLock(context);
        Toast.makeText(context, "Don't panik but your time is up!!!!.", Toast.LENGTH_LONG)
                .show();
        Log.d("Taxeeta:PullPendingRequets", "CallService Location");
        context.startService(new Intent(context, PullPendingRequests.class));
    }
}

My AndroidManifest file has

    <service
        android:name="com.taxeeta.support.PullPendingRequests"
        android:enabled="true"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Light.NoTitleBar" />

    <receiver android:name=".com.taxeeta.HomeScreen.OnAlarmReceiver" />
</application>

Output of adb shell dumpsys alarm

 com.taxeeta
    51471ms running, 5248 wakeups
    5248 alarms: flg=0x4 cmp=com.taxeeta/.HomeScreen$OnAlarmReceiver

Output of adb shell dumpsys alarm | grep taxeeta

 ELAPSED_WAKEUP #7: Alarm{409303b0 type 2 com.taxeeta}
    operation=PendingIntent{408ba2d8: PendingIntentRecord{40887be8 com.taxeeta broadcastIntent}}
 com.taxeeta
    5248 alarms: flg=0x4 cmp=com.taxeeta/.HomeScreen$OnAlarmReceiver

解决方案

To fix it, I removed the inner class OnAlarmReceiver and fixed the androidmanifest.xml file.

    <receiver
        android:name="com.taxeeta.support.OnAlarmReceiver"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.NOTIFY" />
        </intent-filter>
    </receiver>
