Android Action Bar icons not showing up. XML not being seen?



Issue:



  • Icons not showing up on action bar of new app. (Compatibility 2.1+)


Troubleshooting:



  • Made sure Android Support Repository and Android Support Library Installed.

  • Four search icons downloaded and placed in res/drawable/ic_action_search.png dir (referenced correctly? I've ommitted the ".png" in my code.)

  • Made sure the library was added in the build.gradle(Module: app) dependency method. (Perhaps compiling the wrong thing?)

  • Tried putting the action_settings item to 'always', No change, still defaults to the drop down. (This is what makes me think my xml isn't being recognized. If this doesn't work my Icon isn't going to show up.)

  • I've triple checked my versions, to try to make it compatible with 2.1 and up, but I could be doing something wrong with my first app here, so maybe check here to be sure I added my libraries, am referencing them correctly and my version numbers aren't messed up.

  • Made sure my titles were in place in the strings.xml

  • tried adding[ app:actionViewClass="android.support.v7.widget.SearchView" ] to the items in my main_activity_actions.xml
