Question

我需要帮助。我正在尝试使用集成的Google Maps V2启动应用。在带有JellyBean的三星Galaxy S2上，它正在我的父亲的S3上工作。但是在HTC Desire和其他一些人身上却没有。我无法找出我做错了什么。

logcat的：

Answer 1

您应该使用SupportMapFragment。

<fragment
class="com.google.android.gms.maps.SupportMapFragment"
...

您的课程必须延长FragmentActivity.

同时确保导入以下内容

import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;

Answer 2

Google Maps V2支持Android 2.2版

Google Maps V2需要在您的设备上安装Google地图和Google Play服务。如果您的设备不包含此应用程序，则您的应用程序无效。

默认情况下，HTC在Android 2.1版下工作

dalvik.system.PathClassLoader.findClass中的java.lang.ClassNotFoundException
