Context is another term that has a special meaning within Android. If you have experience in the field you already know this and can easily respond to this question. However, it is still advised that you take time to review the terminology, processes, and procedures used by an Android developer before the interview. This will help refresh your memory and put this information in the front of your mind, ready to be retrieved during the interview.

William Swansen

"Context, as used within Android, is the context of the current state of the application or object. There are two types of context. The first is activity context, which is attached to the lifecycle of an activity. IT informs the program of the current state of the activity. The other type is application context, which is attached to the lifecycle of the application. This performs a similar function, but at a higher level and is not dependent on individual activities."
