android - 使用 Google Maps API V2 fragment map : 时带有缩放控件的空白 map

Question

我正在尝试使用新的 google maps api v2 实现 google maps，但由于某种原因我没有看到 map 。

我认为问题是我在模拟器上运行时出现的那两行错误:

 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，出现以下错误:

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中的问题相同:http://android-er.blogspot.co.il/2012/12/google-maps-android-api-v2-with-blank.html

据说问题可能出在我的 key 上，所以我使用以下教程重现了它:http://android-er.blogspot.co.il/2012/12/displaying-sha1-certificate-fingerprint.html .但这仍然对我没有帮助。

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(手动添加允许在模拟器上使用 google map v2 的两个文件之后)以及运行 android 2.2 的摩托罗拉 Defy 上看到了相同的结果。

也许我使用了错误的 debug.keystore？我正在使用我的 User.android 文件夹中的文件。如果是这样，我该如何找到正确的文件？

编辑:我的 eclipse 说我的调试 key 在默认文件夹中。所以我重命名了 debug.keystore 文件并运行 Eclipse 重新创建它。这导致生成了一个新的 SHA1 key 。我用它创建了一个新的 Google Maps API v2 key ，但结果还是一样。我仍然看不到 map 。

EDIT2:愚蠢的我，我选择了 Google Map API V2 而不是 Google Maps Android API V2。 这个问题可以关闭。谢谢。

Answer 1

就我而言，我选择了 Google Maps API V2 而不是 Google Maps Android API V2。更改后问题消失了。所以这段代码非常适合创建全屏 Google map ，问题可以关闭。

谢谢。
