Question

我正在处理搜索存储在DB中的位置的任务。之后，我必须在相应的位置放一个别针。我在快速搜索框（QSB）上进行了修改，以搜索我的应用程序中的数据库。对于那个QSB性能我遵循API演示中的搜索字典示例。当我点击搜索建议时，它会重新加载当前活动并将引脚放在上面。单击后退按钮时，它会在Logcat中显示以下异常。为什么会这样。任何的想法？

我的日志CAT值：

Android中的活动线程异常是什么？请帮助。

Answer 1

我遇到了同样的问题，经过搜索后我发现了这篇关于同一问题的帖子

https://novoda.lighthouseapp.com/projects/63622/tickets/157-leak-receiver-searchresult

它表明在您的应用程序中使用多个map activities时问题会出现。

所以在我的应用的 manifest.xml 文件中，我使每个地图活动在一个单独的进程中运行：

android:process=":p1"
android:process=":p2"

您可以在Android文档中详细了解此信息。 http://developer.android.com/guide/topics/manifest/activity-element.html#proc

Answer 2

您在异常日志中有答案..

您是否错过了对unregisterReceiver（）的调用？

您是否在申请中注册了广播接收器？如果是，您应该在销毁活动之前致电取消注册接收器。

修改

您好..

我看了一下ConnectivityBroadcastReceiver，我发现了这个讨论......

on Android Developers

on android google code

他们有同样的问题。你可以发布你的代码吗？

Answer 3

我也遇到了这个问题。对于我的情况，我使用电池指示器，并且在onPause（）或onDestroy（）时没有销毁它。刚发现电池指示灯是广播接收器。

要解决我做了以下事情：

@Override
public void onPause()
{
    super.onPause();

    unregisterReceiver(myBatInfoReceiver);
}

@Override
public void onResume()
{
    super.onResume();

    registerReceiver(myBatInfoReceiver,
            new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
}

Android中的ActivityThread异常？
