I am working on an open-source project based on Phonograph. I renamed the package/domain name and I am getting the error: "C:\Users\user\AndroidStudioProjects\Rya Music Player\Play Store\Rya Music Player\app\src\main\java\com\urbannet\ryamusicplayer\glide\BlurTransformation.java:19: error: cannot find symbol
