I updated my android all the firmware and other updates, but it still has android market.. I downloaded APK for google play but I can't and don't know how to transfer it to my android phone. Like it's on my computer like what do I do to install it and make sure google play is installed and works on my android phone I have a Mytouch 4g. I just want to be able to use apps like Vine and Snapchat, it tells me I have never used google play and my device isn't registered but how am I supposed to do that if I don't even have google play and the stupid thing is still on android market...
