不幸的是已经停止工作,android studio

我是Android编程的完全初学者,我知道这已经发布了很多次了。 问题是,我已阅读过每一篇文章,而且我似乎没有像每个人都发布的任何错误,我认为我正确地遵循了每一个基本步骤。 它应该只是暂时登录Facebook,仅此而已。 我尝试在本机模拟器和Genymotion上运行,结果相同。 现在已经3天了,这让我发疯了。

我的logcat:

答案 0 :(得分:0)

您的MyApplication课程是否在com.example.tasos.likefeed_4下。如果没有提供正确的软件包,它会驻留在或尝试从清单中删除android:name=".MyApplication"并运行它(如果MyApplication在您的应用中没有自定义内容)。

希望这有帮助。
