android – 使用广播PendingIntent和AlarmManager.setAlarmClock()丢失Intent额外内容

我像这样创建一个PendingIntent：

Intent intent = new Intent(context, AlarmReceiver.class);
intent.setAction("Foobar");
intent.putExtra(EXTRA_ALARM, alarm);
intent.putExtra(EXTRA_TRYTWO, tryTwo);
intent.putExtra(EXTRA_BEGAN_TIME, beganTime);

return PendingIntent.getBroadcast(
        context, (int) alarm.getId(), intent, PendingIntent.FLAG_UPDATE_CURRENT
);

警报变量是Parcelable.我像这样安排PendingIntent：

PendingIntent alarmModifyPendingIntent = PendingIntent.getActivity(
        context, 0, editIntent, PendingIntent.FLAG_CANCEL_CURRENT
);

am.setAlarmClock(
    new AlarmManager.AlarmClockInfo(time, alarmModifyPendingIntent), pendingIntent
);

如上所示创建变量pendingIntent的位置.

AlarmReceiver对象在正确的时间接收onReceive中的Intent.但是,此Intent不包含我设置的额外内容.例如,intent.getParcelableExtra(EXTRA_ALARM)返回null.

Android 7.0(API级别24)至少使用LG G5会出现此问题.

使用FLAG_CANCEL_CURRENT或FLAG_ONE_SHOT也不起作用.

解决方法:

The alarm variable is a Parcelable.

It is not safe to put a custom Parcelable in an Intent that is delivered to another process.对于Android 7.0上的AlarmManager尤其如此.

你需要用其他东西替换那个Parcelable,比如byte [],其中you manually convert your Parcelable to/from that byte[].
