4. twitter.com/@nshred medium.com/@nickskelton A common theme 1. Release Paralysis 2. Messy code 3. Hey Joe’s
5. 1. Release paralysis Why can’t we ever release? WHY? WHY? WHY? WHY? WHY?
6. twitter.com/@nshred medium.com/@nickskelton Don’t mix bugs and features • We were skipping releases because we mixed features with bug fixes • The solution was to create 3 Branches (alpha, beta, production) with 3 corresponding CI jobs. • Separating stable changes from unstable changes, enabled releases to happen.

9. twitter.com/@nshred medium.com/@nickskelton What does this mean for Android?
10. DEMO
11. twitter.com/@nshred medium.com/@nickskelton 2. No more train wrecks
12. twitter.com/@nshred medium.com/@nickskelton Static Code Analysis • Lint (Android specific) • DRY (don’t repeat yourself)/ CPD (copy paste detector) • CheckStyle (code style) • SonarQube (standalone code analysis for the serious projects)
13. twitter.com/@nshred medium.com/@nickskelton Unit Tests • Catch the problems before they happen
14. DEMO
15. 3. Long support calls You have an old version, upgrade your app.
16. twitter.com/@nshred medium.com/@nickskelton Versioning
17. twitter.com/@nshred medium.com/@nickskelton Versioning git rev-list HEAD --no-merges --count http://www.androidshortcuts.com /finding-the-perfect-versioncode
