If I use new " V7 Appcompat library ", do I still need " V4 Support Library " for a minimum SDK = 7?

I am migrating from Action Bar Sherlock to Action Bar compat. I remove ABS and I had support-v4-google maps in it, I got errors. I will add the v4 directly to the project now to see if it solve, but I want to know: I don't really understand from the documentation if libraries are redundant or complementing? Thanks for advice, pointers etc. EDIT: This is the error that make me added v4 with "external jar... " It solve it. ``` The type android.support.v4.app.TaskStackBuilder$SupportParentable cannot be resolved. It is indirectly referenced from required .class files ``` But if u say i should not add v4 if already have v7 how do I explain it to Eclipse? Relevant post, the solution was to add v4 here. The hierarchy of the type activity is inconsistent when extending ActionBarActivity Edit 2: The v4 jar is included in the v7 library project if done following these steps point by point: http://developer.android.com/tools/support-library/setup.html#add-library My setup is : - Android 4.3 : unchecked - APrivate Lib: unchecked - v7-app.../src : checked - v7-app.../gen : checked - ADependencie: unchecked - raw v7 jar : check - raw v4 jar : check
