Answer 2

You can probably use Android.Lint

Android Lint is a new tool introduced in ADT 16 (and Tools 16) which scans Android project sources for potential bugs. It is available both as a command line tool, as well as integrated with Eclipse (described below), and IntelliJ. The architecture is deliberately IDE independent so it will hopefully be integrated with other IDEs, with other build tools and with continuous integration systems as well.

Here are some examples of the types of errors that it looks for:

1. Missing translations (and unused translations)
2. Layout performance problems (all the issues the old layoutopt tool used to find, and more)
3. Unused resources
4. Inconsistent array sizes (when arrays are defined in multiple configurations)
5. Accessibility and internationalization problems (hardcoded strings, missing contentDescription, etc)
6. Usability problems (like not specifying an input type on a text field)
