我有一个地图活动，它使用谷歌地图搜索位置并输出它的地址。我的问题是，它大部分时间都有效，但有时在搜索位置时会崩溃。这是我的logcat：

这是我的代码。有人可以指出为什么会这样吗？

答案 0 :(得分：3)
getFromLocationName(...)为空，则 IllegalArgumentException会引发locationName，如果网络不可用或发生任何其他I / O问题，则会引发IOException。
在LogCat中，我们可以看到getFromLocationName(...)抛出IOException：
java.io.IOException：无法解析来自服务器的响应
所以你有它：问题是网络不可用或发生了其他I / O问题。
