而不是显示logcat，请显示您尝试过的代码。 – NewUser

根据LogCat的问题是这样的：ClassNotFoundException：com.example.networkusage.NetworkActivity – Ridcully

上传代码 –

看起来你com.example.networkusage.NetworkActivity类丢失。

如果在外部库宣布，该jar文件添加到“库”文件夹，并其添加到构建路径，然后建设项目再次。

别忘了干净它也是！

发现我的包名是：

com.example.android.networkusage

和清单是：

机器人：名字= “com.example.networkusage.NetworkActivity”

改变，以便舱单：

机器人：名字= “com.example.android.networkusage.NetworkActivity”
