Question to first steps:
I have a question about the first steps: after cordova build I could run cordova run android. The app starts on the device and displays the Codova icon. Is it possible to continue without Android studio? If yes, how?
Have you got a simple example only for POI?
If I understand your question correctly then yes you can choose another alternative instead of Android studio, such as Eclipse. However, I strongly recommend building your application with our SDKs with Android studio.
