在Android中将SDK版本更新为24.3后，所有库均显示错误

Question

All libraries ware fine before updating the sdk. Just now I update the sdk through sdk manager and everything is out of control now. All libraries are showing only one cross mark on its folder and no error inside. I have taken some images to show something here.

v7 lib:

Unfortunately I couldn't found any issue inside the library.

google-play-service-lib:

same issue.

Fortunately I have found some errors in Error Log, but its not sufficient for me to resolve.

Android SDK Manager:

The main issue is it deleted all R.Java classes from all projects in which these libraries are involved.

Can anyone knows how to resolve this problem.

Answer 1

Happened with me also .. somehow the files mainly ( R.java ) got corrupted after latest sdk update, that's why you can observe support library name also changed from appcompat_v7 to android-support-v7-appcompat .

Solution that worked for me is remove all the libraries from workspace which have error & re-import them to my workspace.

For example - for importing support library appcompat_v7 , re-import it from your sdk location:

(\\adt-bundle-windows-x86-20140702\\sdk\\extras\\android\\support\\v7\\appcompat)

Likewise do re-import for other corrupted libraries.

Finally I solved the issue by deleting two apis ie API 22(Android M) and Tools. Don't know why the issue is coming after installing these APIs. After all I'm able to get R.java classes and recompile the apps. I have attached a image of both packages after deleting.
