这一次奏效了。我不知道我做了什么来杀死它。App Force 在任何事情发生之前关闭。下面是LogCat

10-21 15:34:14.503: E/AndroidRuntime(22129): java.lang.RuntimeException: 无法实例化活动 ComponentInfo{com.bigtexapps.android.DropBubble/com.bigtexapps.android.DropBubble.Menu}: java.lang .ClassNotFoundException: com.bigtexapps.android.DropBubble.Menu 在加载器 dalvik.system.PathClassLoader[/data/app/com.bigtexapps.android.DropBubble-2.apk]

看起来你的问题在这里：

java.lang.ClassNotFoundException: com.bigtexapps.android.DropBubble.Menu

确保任何 3rd 方 jar 文件位于项目的 /libs 文件夹中。

在旧版本（r16 及更低版本）中，处理此问题的方法是将您的 3rd 方 jar 放入任何文件夹，然后将该文件夹添加到项目路径中。Google 在 r17 中对此进行了更改，以便将所有第 3 方 jar 文件放入 /libs。

我认为您没有将 jar 与您的 apk 捆绑在一起。您需要做的只是配置您的构建路径设置并检查 eclipse 的导出选项以获取相应的 jar。
