崩溃的 GoogleWrapperSample (OpenStreetMap)
我遇到了 GoogleWrapperSample for OpenSteetMap（我使用 osmdroid 最新 jar - 3.0.8）。它编译得很好，但模拟器（Google API 2.2 设备）会抛出一个带有“活动没有响应”消息的 toast，仅此而已。没有错误/警告，因为它是 osmdroid 类中的记录器，所以我只能接收一些日志信息。 LogCat 给出这样的内容：
02-14 13:21:20.246: W/System.err(968): 38 [main] INFO org.osmdroid.views.MapView - Using tile source: org.osmdroid.tileprovider.tilesource.XYTileSource@44eb5260

02-14 13:21:30.207: I/dalvikvm(968): Wrote stack traces to '/data/anr/traces.txt'
有人让这个示例工作吗？我不知道如何解决这个问题。
也许，它以某种方式与通过网络获取 OSM 图块或类似的东西有关 - 我们有代理连接，因此 https 和 SSL 端口不可用（但设备上的所有网络都可以）。
UPD .
在 HTC Desire 上它可以正常工作，但 OSM 地图不可用 - 只有一个网格。另一方面，谷歌地图还可以。
LogCat 包含以下内容：

在模拟器上没有任何进展。 我认为“无法获取连接工厂客户端”是我的问题的原因，但不知道解决此问题的方法。
I have a problem with GoogleWrapperSample for OpenSteetMap (I use osmdroid latest jar - 3.0.8). It is compiling fine, but the emulator (Google API 2.2 device) throws a toast with "Activity is not responding" message and nothing else. There are no errors/warnings and as it is a logger in osmdroid classes I can only receive some logging information. LogCat gives something like this:
02-14 13:21:20.246: W/System.err(968): 38 [main] INFO org.osmdroid.views.MapView - Using tile source: org.osmdroid.tileprovider.tilesource.XYTileSource@44eb5260
02-14 13:21:20.316: W/System.err(968): 113 [main] INFO org.osmdroid.tileprovider.modules.MapTileFileStorageProviderBase - sdcard state: mounted
02-14 13:21:20.336: W/System.err(968): 129 [main] INFO org.osmdroid.tileprovider.modules.MapTileFileStorageProviderBase - sdcard state: mounted
02-14 13:21:30.166: I/dalvikvm(968): threadid=3: reacting to signal 3
02-14 13:21:30.207: I/dalvikvm(968): Wrote stack traces to '/data/anr/traces.txt'
Has anyone got this sample working? I have no ideas how to solve this problem.
Maybe, it is somehow connected with getting OSM tiles via network or something like that - we have a proxy connection so https and SSL port are not available (but all in all network on the device is ok).
UPD.
On HTC Desire it works properly but OSM map is not available - there is only a grid. On the other hand, Google map is ok.
LogCat contains this:

On emulator there is no progress.
I think that "Couldn't get connection factory client" is the reason of my problem but have no idea about the way to fix this.

有两种情况可能会出现应用程序无响应（ANR）：
ANR 的常见原因是（停滞的）网络操作或昂贵的计算。
有很多关于如何解决这个问题的帖子（例如此处或这里），但最大的帮助可能是Android API。
我快速浏览了示例代码，我不确定，但也许
onResume()中调用的setMapView()方法花费的时间太长。您可以通过注释该行来测试这一点。否则，请检查模拟器上的 traces.txt 文件以获取线索和/或将日志记录语句添加到代码中以查明哪个操作花费的时间太长。至于您的“无法获取连接工厂客户端”错误，该问题已在此处得到解答
There are two situations where an Application Not Responding (ANR) may occur:
Common causes of an ANR are (stalled) networking operations or expensive calculations.
There are a number of posts on SO on how to solve it (e.g. here or here), but the biggest help is probably the Android API.
I took a quick look at the sample code, I'm not sure but perhaps the
setMapView()method that is called inonResume()takes too long. You may be able to test this by commenting that line out. Otherwise, check the traces.txt file on the emulator for clues and/or add logging statements to your code to pinpoint which operation is taking too long.As for your "Couldn't get connection factory client" error, that question has already been answered here
