The PhoneGap developer app is compatible with Android 4.0.3 and up. So ideally it should be compatible with your phone. Can you elaborate further on the steps that you are following ?
Thanks for answering! I just went to play store and typed phonegap. At the top of the list I found Phonegap Developer without a 'FREE' in the bottom right corner. When I clicked the icon I got the message 'Your device is not compatible with this version'. The problem seems to lie with the 'and up'. Phonegap Developer obviously isn't compatible with Android 5.1.1. I tried with a 4 years old Samsung Galaxy Note 8 and was able to download and install the app. It works with limited functionality (no gestures).
