Question

I had 2 BroadcastReceivers for watching SMS status. Code:

//纽约总部-when the SMS has been sent纽约总部-
   registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
        ...................
        ...................
        }, new IntentFilter(SENT));
    //纽约总部-when the SMS has been delivered纽约总部-
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
        ...................
        ...................
        }, new IntentFilter(DELIVERED));

这两家接收器位于一个称为“信箱”的程序中。一切工作都很出色,但以下情况令我失望。当用户改变屏幕取向和投向一种例外情况时,申请被压制。 LogCat告诉我,该方案不想第二次登记广播接收人。我认为,不存在问题,并增加了一个诱杀旗帜,以便今后在OnCreate(OnCreate)跳出电动。但是,即使电离层监测系统(SMS)的号召第二次出现,第一次改变屏幕的定位,是LogCat的一个新征兆:

活动泄漏

一旦出现这种情况,就不可能跟踪SMS的状况,接收器不会工作。但是,如果用户试图发挥并继续改变方向,则不管怎样,错误都不出现。

纽约总部

Who knows, what happened? The workaround like a block permission to change orientation not interesting. I need to understand what happened here and solve a current problem.

此外,还混淆了来自LOGCat的下一个短语。

难道你没有向未出庭者发出呼吁吗?

......为什么发生这种情况?

Answer 1

当用户改变时,屏幕取向和roid弃一种例外申请被抑制。

您应在onPause(>>上对接收人进行保留,并在onResume(>上登记。这样,当安乐斯摧毁并重新调整组合改变的活动时,你仍将有接收者。
