Error "Unresolved reference: _root_ide_package_" after changing the package name

Question

When I changed my package name and rebuilt the project, Android Studio put before many class names this string _root_ide_package_.com.example.<myprojectname>. And I have this error Unresolved reference: _root_ide_package_. Any ideas how to fix it?

Answer 1

While posting a code example would help, I had a similar issue and resolved it by doing a Replace in Path across the source tree and replaced all instances of _root_ide_package_.com.example.<myprojectname>. with nothing.

Answer 2

Just remove anything before the class name, for example:

_root_ide_package_.com.<project_name>.APP

Remove _root_ide_package_.com.<project_name>.
