I have no idea what to do or what is wrong
I have spent the last several hours trying to figure out how to make the icon show up. Ive gone through all the old questions which complain about how depreciated the video is and the solutions they have seem depreciated I think. Ive reworked all the code from the RecipientsActivity over a dozen times and I feel like Ive broken my code and tinkered with other files too much and I just have no idea what to do since I don't understand at all why none of the things I have tried dont work.
finally figured it out. In the recipients.xml file the line android:showAsAction="always" gave off a red swiggle line so I switched it to app:showAsAction="always" as it was recommended. This switched the app from showing the icon when i hit the settings button (hardware button) to being in the top right corner as it should be.
