I have an android app that I've been working on for a while. I recently found that on phones such as the nexus the menu button does not appear. According to this post, the menu button is deprecated for that version of android and my options are to either implement the action bar or change my build target to a lower one. Due to time constraints I wanted to change the build target as a temporary fix until I get the time to implement the action bar.
I followed the instructions here, but when I get to the Android section in properties I don't have any other options for Build Targets. The only option available is 4.2.2, and I need 2.3.4 or lower. What can I do to change the build target or is implementing the Action Bar my only option?
