So far so good, we have our cake, but can we eat it? The answer comes about 5 minutes after we hit the 'Launch' button. The default Android emulator comes together with the Android SDK and can be found in the 'tools' folder.
The great thing about using an emulator for development is that it gives you an opportunity to develop applications without having a real Android device. The main objective before releasing an application is to find bugs and design imperfections. When developing Android applications, you have to keep in mind all the different Android OS versions and various screen sizes and resolutions. So, what should we do? That's easy - start using a properly fast Android emulator.
Testing on multiple mobile devices is costly, time consuming and the default Android emulator is notoriously slow.
