I have used the ActionBarSherlock+HoloEverywhere combination for a while, and it is working good. However, the time has come to migrate to the official Google AppCompat library.
If I am right, the latest version of HoloEverywhere should work with AppCompat. I can use the AppCompat library easily, but on older devices, it uses the default, non-Holo themes, like it should. When applying the HoloEverywhere project, I am getting Attribute "_____" has already been defined errors (102 of them), which points to two different folders, \res\values\abc_attrs.xml and \res\values\attrs.xml in the HoloEverywhere project.
Is it a known issue, or am I doing something wrong? If yes, how should I do it? For the record, I am using IntelliJ IDEA.
As @langerhans pointed out, the latest HE contains the ABC, so there is no need to add the ABC library a second time, after deleting it, my issues are solved.
