android - 提示 : Apache Cordova and Android: Unable to instantiate activity ComponentInfo

Question

这个真的让我很紧张。经过 2 到 3 天的查阅各种资源后，我找到了一个常见问题的解决方案。

上下文基于使用 Android http://j.mp/MB1pTM 提供的 PhoneGap 演示。在使用 PhoneGap API 文档为 Android 4.0.3 进行精确设置时，演示本身对我来说失败了。我收到以下错误消息:

我的设置与@curlyreggie 相同。我通过执行以下操作使其正常工作:

右键点击 Cordova-2.4.jar -> Configure Build Path 然后在选项卡 Order and Export 中，我确保列表按以下顺序排列:

1. Android(在我的例子中是 Android 3.0)
2. 安卓依赖
3. Cordova ....
4. ..../源
5. ..../gen
