我正在尝试查找使用PendingIntent
调用的BroadcastReceiver
AlarmManager
。
我正在使用PendingIntent.getBroadcast()
使用与调用它相同的参数,但它永远不会返回null。
public MyObject(Context context, AnotherObject object) {
Intent i;
i = new Intent(context, MyReceiver.class);
i.putExtra(AnotherObject.SOMETHING, "string");
i.putExtra(AnotherObject.SOME_BOOL, true);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, PendingIntent.FLAG_NO_CREATE);
if (pi == null) {
Log.v("help", "PendingIntent is null");
}
else {
Log.v("help", "PendingIntent is not null");
}
}
这是我的测试驱动程序:
that = new MyObject(this, object);
LogUtil.startAlarm(this, object);
that = new LogUtil(this, object);
这是startAlarm
:
public static void startAlarm(Context that, AnotherObject object) {
Intent i;
i = new Intent(that, MyReceiver.class);
i.putExtra(AnotherObject.SOMETHING, "string");
i.putExtra(AnotherObject.SOME_BOOL, true);
long interval = 60 * 1000; // Minute
long first = SystemClock.elapsedRealtime() + interval;
PendingIntent pi = PendingIntent.getBroadcast(that, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
// Schedule the alarm
AlarmManager am2 = (AlarmManager) that.getSystemService(Context.ALARM_SERVICE);
am2.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, first, interval, pi);
Log.v("help", "Started alarm");
}
这是我的日志输出:
09-02 11:18:54.330: VERBOSE/help(9621): PendingIntent is not null
09-02 11:18:54.330: VERBOSE/help(9621): Started alarm
09-02 11:18:54.330: VERBOSE/help(9621): PendingIntent is not null
为什么它甚至在我开始闹钟之前就说它永远不会为空? getBroadcast()
不应该返回null吗?
答案 0 :(得分:3)
嗯,为什么?我试图找到使用AlarmManager调用的BroadcastReceiver的PendingIntent。
我正在使用PendingIntent.getBroadcast()使用与它一起调用的相同参数,但它永远不会返回null。
不应该这样。如果还没有一个用于等效的基础PendingIntent
,它将创建Intent
。有人可能会争辩说方法名称应该是createBroadcast()
以使这一点更清晰。
