Question

我的应用在Android模拟器中请求位置更新后停止工作。这仅适用于3.0以上的Android版本。任何代码如下

lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

该应用停止工作。这是在这些版本的模拟器中的常规行为还是我做错了什么？

更多信息：如果我为Android 2.3或更低版本启动模拟器，则会正常捕获异常。这种情况在其他版本中没有发生。

Answer 1

这是预期的。在更新的版本中，Android处理UI线程的工作要严格得多。

解决方案是在位置更新可用时（在onLocationChanged（）方法中）使用handler更改UI线程上的UI。
