Question

我想使用新的谷歌地图api v2实施谷歌地图，由于某种原因我看不到地图。

我认为当我在模拟器上运行时，问题就是那两行错误：

 E/ActivityThread( 1373): Failed to find provider info for com.google.settings
 E/ActivityThread( 1373): Failed to find provider info for com.google.android.gsf
.gservices

当我在设备上运行应用程序时，会产生以下错误：

Could not find class 'maps.j.k', referenced from method map.y.ae.a

我的问题看起来与此链接相同：http://android-er.blogspot.co.il/2012/12/google-maps-android-api-v2-with-blank.html

有人说问题可能是我的关键，所以我使用以下教程复制了它：http://android-er.blogspot.co.il/2012/12/displaying-sha1-certificate-fingerprint.html。但这仍然没有帮助我。

支持文件当然会添加到项目以及Google Play服务库中。我在模拟器上看到相同的结果（手动添加允许在模拟器上使用谷歌地图v2的两个文件）以及运行android 2.2的motorola Defy。

也许我使用的是错误的debug.keystore？我在我的User.android文件夹中使用那个。如果是这样，我如何找到正确的文件？

编辑：我的eclipse说我的调试密钥在默认文件夹中。所以我重命名了debug.keystore文件并运行Eclipse以重新创建它。这导致生成一个新的SHA1密钥。我用它来创建一个新的Google Maps API v2密钥，但结果仍然相同。我仍然无法看到地图。

EDIT2：愚蠢的我，我选择了谷歌地图API V2而不是谷歌地图Android API V2。这个问题可以关闭。感谢。

Answer 1

在我的情况下，我选择 Google Maps API V2而不是 Google Maps Android API V2。改变之后问题就消失了。所以这段代码完全可以创建一个全屏谷歌地图，问题可以关闭。

感谢。
