我有一个带有BroadCastReceiver类的Android库项目和一个调度程序类，它定义了为BroadcastReceiver设置重复PendingIntent的方法
//delay for AlarmManager setRepeating method in seconds
//id as requestCode for PendingIntent
public static void scheduleBroadcast(Context context,int delay,int id){
Intent intent = new Intent(context, SuperReceiver.class);
intent.putExtra(KEY_DELAY, (long)(delay * 1000));
intent.putExtra("APP_NAME", context.getPackageName());
long timeGap = (long)(delay * 1000);
PendingIntent alarmIntent = PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis() + timeGap, timeGap,
alarmIntent);
}
接收者
@Override
public void onReceive(Context context, Intent intent) {
Log.e("Chirag-Library","SuperReceiver Received!");
long delay = intent.getLongExtra(BScheduler.KEY_DELAY, -1);
Log.e("Chirag-Library","Delay is "+delay+" ms");
Log.e("Chirag-Library", "By App called "+ intent.getStringExtra("APP_NAME"));
Log.e("Chirag-Library",context.getPackageName());
}
我正在使用这个项目作为我的两个应用程序中的依赖项，这些应用程序以完全相同的方式在其清单中定义接收器
<receiver android:name="com.chirag.library.SuperReceiver"/>
我从两个具有不同延迟值的应用程序中调用scheduleBroadcast（）。
在com.chirag.appone
中BScheduler.scheduleBroadcast(getApplicationContext(), 10,111);
在com.chirag.apptwo
中BScheduler.scheduleBroadcast(getApplicationContext(), 60,999);
当任何一个PendingIntent被触发时，是否为这两个应用调用了OnReceive（）？
是因为PendingIntents具有相同的接收器意图吗？
Logcat显示在OnReceived中同时触发的日志秒

对我来说更令人困惑的是，为什么距离appone的10s延迟只能在60秒延迟到apptwo之后被触发一次？
这到底发生了什么？
答案 0 :(得分：0)
当任何一个应用程序中的两个应用程序都调用了OnReceive（） PendingIntent被解雇了吗？
没有。 原因如下： 导入PendingIntent的Intent是显式Intent，因此使OnReceive应用程序上下文特定，因此两个应用程序都有自己的接收器，即使名称相同。
对我来说更令人困惑的是为什么因为appone的10s延迟被解雇了 从apptwo延迟60s只有一次？
在对setRepeating（）进行一些错误研究后，我发现了这个https://code.google.com/p/android/issues/detail?id=161244
在API＆gt; = 21上说setRepeating（）间隔值重置为60秒，如果小于60秒（这没有记录），这恰好是我的情况。
因此，他们第一次似乎以不同的时间间隔（当前时间+ 10秒和当前时间+ 60秒）发射，然后两者都以60秒的间隔触发。而且，setRepeating（）并不总是产生秒精确事件，所以两者都是我的onReceive似乎同时被解雇导致了混乱
