我的应用程序存在很大问题。
当它关闭（不在后台）并且收到广播时，应用打开并置于前景。
非常讨厌。
我将相同广播接收器的代码放在一个空项目中，问题不会出现。
当具有错误的应用激活接收器时，上代码将复制到AndroidMonitor中。
更低，应用程序没有问题。

这是接收者的代码：
public class CreatoreNotificaAllenamento extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent in = new Intent(context, MainActivity.class);
long[] pattern = {0, 500, 1};
PendingIntent pi = PendingIntent.getActivity(context, 01234, in, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.icona_notifica)
.setContentTitle(context.getString(R.string.notifica_titolo_ricordo_allenamnto))
.setContentText(context.getString(R.string.testo_notifica))
.setVibrate(pattern)
.setAutoCancel(true);
mBuilder.setContentIntent(pi);
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mBuilder.build());
}
这是我用来启动AlarmService的方法：
public static void setAlarm(Context c, Date data) {
AlarmManager alarmMgr = (AlarmManager) c.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(c, CreatoreNotificaAllenamento.class);
PendingIntent pi = PendingIntent.getBroadcast(c, 0, intent, 0);
if(System.currentTimeMillis() > data.getTime()) {
Calendar cal = Calendar.getInstance();
cal.setTime(data);
cal.add(Calendar.DAY_OF_YEAR, 1);
data = cal.getTime();
}
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, data.getTime(),
1000*60*2, pi);
}

我怀疑。当您的应用未运行且触发了Application时（例如，在BOOT时间），Android会为您的应用创建新的操作系统流程，并创建自定义onCreate()类的新实例，并且在该实例上调用startActivity()。在您的代码中，拨打自定义onCreate()课程Application内的Activity。当然，这会将您的应用程序带到前台并显示已启动的startActivity()。你可能不希望这种情况发生。
您可能应该从自定义onCreate()课程的Application中移除#import <CommonCrypto/CommonCryptor.h>来电并将其放在其他位置。

由于您已在清单文件中定义广播，因此您的应用在接收广播时会自动打开。
要解决您的问题，您必须在您的班级注册广播接收器。然后在onResume方法中注册广播接收器并在onPause或onDestroy方法上取消注册广播接收器。您的问题将得到解决。
