title: Android studio cannot resolve ActionBarActivity
body: <p>I have tried invalidating the caches and restarting but it still shows up and will not compile and run as it used to before. I tried renaming the class file if i remember correctly and must have changed the name on something that made this how up. It also gives me the same error where findViewById, .oncreate, and setContentView. I migh have also renamed or tried to rename one of the packages because it was examplecom and it wouldnt allow me to upload it.</p>
