why does R does not exist error come in android?

Question

packages/apps/Myfolder/src/com/android/myfolder/MyFile.java:196: package R does not exist
                  addPreferencesFromResource(R.xml.myfile);
                        


        

Answer 1

Also make sure to include your current Activity in the AndroidManifest.xml, inside the application tags. So if MyFile is your Activity subclass, you should have something like this in it:

        
             
                 
             
        
        ..

Although what's actually in there depends on your activity. More information about this at: http://developer.android.com/guide/topics/manifest/manifest-intro.html
