Besides official Android SDK emulator which is damn slow and ugly, I have found Genymotion is quite good and awesome. In Windows platform Bluestack has done a very good job and their Android emulator is very fast and totally usable but sadly there is no Linux edition of Bluestack.
I found Genymotion could be a good replacement of Bluestack for Linux.
Installation of Genymotion is quite easy, you just need to download the bin file and then give execute permission to it and then run the file. Plus as you should have Virtualbox installed on your computer, it is a prerequisite. After executing the file, the setup program will take care of everything and install Genymotion properly for you. However, for downloading and using Genymotion you must register in their website and that is the only thing I really don’t like.
Here you can find install process of Genymotion step by step. And if you want to try any other emulator rather than Genymotion take a look at here.
And still of course for development purpose my recommendation is official Android SDK emulator.
I have also compiled some of the fastest and latest android emulators for pc and mac. I think you should check out that. I also have reviewed many of those emulators seperately which you can check out here
OK, sure. Thanks for that.
