Answer 1

1) Replace all of Images,Icons with vector drawable

2) Turn on pro guard like following goto build.gradleapp level

and put these lines

**shrinkResources true

minifyEnabled true**

3) Remove unused classes,drawable and methods and strings and use LINT's private method analyser which reduces method count

JAVA's Hidden cost

4) In android studio 2.2 and above they have added apk analyser tool in Build menu. Use that to analyse APk

5) if app size goes beyond 100mb use feature called split apk. there are two methods of spliting apk ABI and Density Splits
