Hello everyone. I participate in a project - android app development and my work is to make the app to upload audio files (m4a) after recording, and cvs files to amazon server (aws.amazon.com). Can you give me general guidelines? How to start? My first steps? Advice? General speaking, android studio is better or eclipse? The amazon aws has a few mobile services, for example Cognito, Device Farm, Mobile Analytics and SNS. Should I use some of them? Thanks in advance.
