It is common that during an interview for any software development position, you will be presented cases and asked to create the code to resolve the case or solve an issue. This is especially true for Android application developers. While you cannot be prepared to create every line of code the interviewer may ask you about, you should be able to address the more common ones. The interviewer seeks to confirm your ability to quickly develop code when presented with a common code case. If you cannot create the code they are asking you about, acknowledge this and then detail how you would do it using typical resources available to developers.
