Hello Ruban1,
At this point we can see that when there is a .config file in the kernel/ directory or a config/ directory exists in the kernel/include/ directory, the shell prints the error message seen at the beginning of this paragraph and exits. the problem is to delete the 2 objects. Go to the kernel/ directory and look for the .config file. If you go to the kernel/include/ directory, you will find the config/ directory! Go into the directory and see that it is empty (an empty directory can cause the entire project to fail to compile, and the details affect the success or failure!).
After removing the config/ directory, go back to the top of the Android project, re-execute the source and lunch commands, and recompile.
Regards
