The purpose of Android BrainGym is to limber up your mind for interview questions.

While no tool, blog or site is guaranteed to cover every single situation in which an employer may place you, Android BrainGym will at least get you thinking about the concepts you may be asked about, and its intent is to "exercise" you in various ways that, with repetition and practice, should help reinforce concepts.

Android BrainGym is best used by those with some experience creating and publishing Android projects, perhaps one or two years' worth of experience. The basics will allow you to something on which to build, and new terms here may make sense when considered in context with other terms.

You can use Android BrainGym anytime, anywhere. If you want an activity to build your confidence as you're sitting in a reception area, or just before you go on that video-conference call, you'll find this app to be helpful.
