My Collection of Android libraries

A few tips on choosing Android libraries

  • Make sure to check the size of the library as well as its dependencies because of the 65K methods limitation of Android App.
  • Make sure any annotation process and code generation happens at compile time.
  • If it is an UI component library, make sure it is compatible with Material Design.
  • Be sure to check the stars and activies on Github. Knowing the limitations and issues of your libaries.
