I am Java developer and I just started to learn Android development. I like it. I want to make it as my full time job. I want to start as freelancer work and want to work on online websites who display projects for bids. My question is that how long it would take to become an Android developer who actually can work as professional if someone know Java. I think it would take 6 months for me to learn all and publish 4 - 5 Apps on Google. Second is there enough projects of Android that one can make at least $2500 per month? Is Android projects are short term projects like few days or a week ?I see lot of developers in market what is scope as an Android developer? Are there enough projects in market to feed all Android developers?
