android 运行时出现的错误

我选择logcat里面的error,运行程序时出现以下错误,这是什么呢?看不懂呀。运行多次后出现Unable to instantiate application android.app.Application: java.lang.NullPointerException。而我在另一个文件夹下载的项目做了一样的修改,运行起来一点儿问题也么,我搞不懂了。

AndroidManifest.xml中的application里的android:name去掉试试

  <application
        android:name=""//去掉

或者自己继承application重新写一个

凌云志轩 错误时这样的。手机上先是黑屏5S左右,然后APP重新起来,正常运行的。

凌云志轩 <application android:name=""我的上面已经去掉了。奇怪呀,我好的那个版本只添加了一个按钮的响应函数也变的和第一个版本一样了,运行就有这个错误。直接不敢动了。
