Iteration speed

• Use “Instant Run” whenever possible: https://developer.android.com/studio/run/index.html#instant-run
• Genymotion is a fast emulator: https://www.genymotion.com/

Static Analysis

https://developer.android.com/studio/write/annotations.html

• Nullness
• VisibleForTesting

Testing

• Dependency injection
  • Static stuff is hard to mock (unless you use https://github.com/powermock/powermock)
  • Use DI to pass in mock objects for testing
  • Dagger2 is likely the best: http://jakewharton.com/dependency-injection-with-dagger-2/
• Assertion helpers
  • “produces an output which allows you to immediately recognize the problem”
  • https://github.com/square/assertj-android

Optimization

• Strict mode for catching some anti patterns
  • https://developer.android.com/reference/android/os/StrictMode.html
• Proguard for shrinking APK size
  • https://developer.android.com/studio/build/shrink-code.html
