It accomplishes that by providing dynamic binary translation of the device machine code to the OS and processor architecture of your development machine.īasically, it does a lot of mumbo-jumbo to pretend it's an ARM processor - when actually it isn't. Maybe even more.įinally - the emulator launches, only to show how slow it actually is.Īll these performance problems stem from the fact that it emulates an ARM processor so it can run the actual code of your application.
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.
