Suddenly when I was running my android application project, Android Studio shows an error balloon of Internal Error
Then my manifest suddenly got errors saying
java.lang.RuntimeException: Activity name cannot be empty.
I tried disabling the Android Plugin and restarting it back again but no use. I also have error on R not being resolved but I think it is because it can't read my manifest file.
I also tried
Build -> Clean Project but still no luck.
How can I solve this?
