这个debug \\ AndroidManifest错误是怎么发生的？

Question

The screen shot

The project cannot resolve symbol R so I clean the project but the warning is as the pic, how is this happen, I did not do anything to my project.

Answer 1

You are putting an space character (" ") in your "com.pg.MainActivity" activity name attribute. Remove that space char an it should work like a charm. Also, the aapt error is because your Manifest file cannot be parsed, so the resources indexes cannot be generated (aapt is the program that generates the resources indexes). Also, be sure to edit the manifest file of the "main\\AndroidManifest.xml" tab.

Answer 2

清理并重建项目。然后你不会看到那个错误

Answer 3

Remove the extra character at the end in "com.pg.MainActivity" .
After this also perform, Sync Project with gradle files .
Performing a Make Project after this should resolve the issue. Try clean and rebuild if it is required.
