的BroadcastReceiver的onReceiver不叫，AlarmManager

本文介绍了的BroadcastReceiver的onReceiver不叫，AlarmManager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;         ＆所述; /意图滤光器＆gt;     ＆LT; /接收器＆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=".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>
