你应该知道AS使用Gradle，Eclipse不使用。@BlackHatSamurai什么是AS sir，我如何在Eclipse中使用它？你为什么这样降级？Android Studio在各个领域都比Eclipse好。@lusiak你们可能是对的。我还没有切换到android studio。我仍然习惯于日食。当我尝试启动Android Studio时，我无法在手机上运行它。@lose退出Android Studio可能看起来有点复杂，但相信我，它在许多方面都比eclipse好，它有很多快捷方式、功能甚至主题：D我推荐安卓Studio入门教程。当我切换时，我曾经认为它过于复杂，但它似乎比eclipse好得多，一旦你找到了解决方法，它就非常简单：D
