Question

我已经从SO中读过几个Q＆amp; A，并没有找到解决方案。

我的问题是：我从AndroidStudio运行我的应用程序然后得到错误，然后我运行gradlew clean installDebug并且代码工作正常（在AS之外，没有任何更改）。

我没有忘记将我的活动包含在AndroidManifest中。

我正在使用Android Studio 0.8.12，这可以通过真实设备和模拟器（Genymotion）重现。

修改我已经在我的AndroidManifest文件中尝试了“完整路径”和“仅仅类名”来声明活动。并且它仍然没有解释（恕我直言）为什么它通过命令行与gradle一起工作。
