After 7 years of experience in Android development, I have been on both sides as an interviewer and as a candidate. Cracking a technical job interview can be a challenging task and we have to be prepared to demonstrate our knowledge. That's why I decided to create this study guide according to my experiences and try to keep it updated to help others and myself get the dream job when facing a new interview. Feel free to make a pull request and collaborate.

Enjoy it ;)
