package R does not exist after Refactor in Android Studio
Like many other, I like to use some projects as templates. And to make a template project the new project I want to create, I have to refactor the package name. But unfortunately, this process is still not working the whole way through in Android Studio. What happens is that the connection from every “R” call is still pointing to the “old” package name.
Normally you have a lot of Code like this in any project:
R.layout.fragment_list When you have this kind of problem, every Build and Run will fail with the Error:
package R does not exist
Here is the solution:
1. Go to Build and choose “Clean Project”
2. Go to Build and choose “Make Project or make Module”
3. Now, go through every Java file and look for red marked “R’s”
5. And finally, do again a “Clean Project” and the project is ready to be Build or Run.
