在某些设备上的MapView / MapActivity崩溃 [英] MapView / MapActivity crash on some devices
问题描述
我已经通过谷歌的图形页面教程走了，它工作正常，在模拟器上和例如在我的HTC Flyer的。但由于某些原因，我的手机（三星Galaxy I9000）上启动时，它会立即崩溃。
I have gone through Google's MapView tutorial and it works fine on the emulator and for example on my HTC Flyer. But for some reason it immediately crashes when starting it on my mobile phone (Samsung Galaxy I9000).
的崩溃发生在那里，因为就在一开始捆绑的onCreate（）接收为空。我对编译的Android 2.3.3。这是安装在手机上也是如此。该传单采用Android 3.0
The crash happens there, because right at the beginning the Bundle that onCreate() receives is null. I'm compiling against Android 2.3.3. This is installed on the phone as well. The Flyer uses Android 3.0
我会非常AP preciate对这个奇怪的问题的任何帮助。
I'd greatly appreciate any help on this weird issue.

推荐答案
我知道了！你猜怎么了！它是重要的包名！
I got it! Guess what! It's the package name that matters!!!
我发现在谷歌地图样本：
I found a Google Map sample in:
C：\\ Android的SDK \\插件\\插件 - google_apis-google_inc_-10 \\样本\\ MapsDemo
然后我剥夺它，直到它几乎等同于我的。我使用的 bernd.konnerth 作为包名。但对于一些真正疯狂的原因，显然三星手机（也可能是其它设备一样）不接受，只是抛出在发射NullPointerException异常，没有任何进一步暗示可能指向包的名称问题。
then I stripped it down until it was nearly identical to my one. I was using bernd.konnerth as the package name. But for some really crazy reason, obviously the Samsung phone (and probably other devices as well) does not accept that and simply throws a NullPointerException at launch, without any further hint that could point to the package name issue.
当我使用 com.bernd.konnerth 一切工作正常。显然，必须有一个融为一体。在前面。但要注意！似乎有进一步的名字组合不工作。一次偶然的机会我发现，例如 com.android.wifi 行不通的！甚至认为这个包好像没有在android系统命名空间存在。
When I use com.bernd.konnerth everything works fine. Obviously there must be a com. in front. But be warned! There seem to be further name combinations that don't work. By chance I found out that for example com.android.wifi doesn't work as well! Even thought this package does NOT seem to exist in android namespace.

Such things can really drive people crazy! :-(
不过谢谢你的回复速度快的！
Nevertheless thanks for all of your fast replies!
