Android Development, Best Practices

Compiled by Futurice, here is the summary of what they have compiled so far:

• Use Gradle and its recommended project structure
• Put passwords and sensitive data in gradle.properties
• Don’t write your own HTTP client, use Volley or Retrofit libraries
• Use the Jackson library to parse JSON data
• Use Volley or Retrofit+OkHttp+Picasso for networking and images
• Avoid Guava and use only a few libraries due to the 65k method limit
• Use Fragments to represent a UI screen
• Use Activities just to manage Fragments
• Layout XMLs are code, organize them well
• Use styles to avoid duplicate attributes in layout XMLs
• Use multiple style files to avoid a single huge one
• Keep your colors.xml short and DRY, just define the palette
• Also keep dimens.xml DRY, define generic constants
• Do not make a deep hierarchy of ViewGroups
• Avoid client-side processing for WebViews, and beware of leaks
• Avoid testing with Robolectric on Activities, Fragments, and Views

All the details in here.
