As a mobile app developer, we always hope that the smaller the apk file to be released, the better. We do not want image resources that are not used by resource files to be packaged into the apk, lint can solve these problems if you do not want the app to use APIs higher than minSdk or the AndroidManifest file to have exceptions. Android lint is a new tool provided in ADT 16. It is a code scanning tool that helps us identify problems with the code structure, including:

 

1) Layout performance (previously layoutopt tool, which can solve useless layout, too many nesting, and too many layoutopt)
