Las gemas del infinito en el Universo Android

Antes de la creación, existieron seis singularidades. Luego, el universo apareció de un Big Bang y los restos de estos sistemas fueron moldeados en seis gemas concentradas. Las gemas del infinito.

Por suerte o por desgracia en el desarrollo Android tenemos una serie de problemas que resolver, y muchos de ellos son compartidos por el universo entero.

Acá te voy a contar cómo conseguir las seis Gemas del Infinito del desarrollo Android basándonos en las soluciones que tienen en empresas como Twitter, Cabify, Google, eDreams, Tinder, entre otras. Tenés que venir, es inevitable.

20. ⬢ Architecture 20 ⬢ Build time
21. Build Time “ El problema es, que pensás que tenés tiempo. Jack Kornfield 21
22. Build Time 22 Modularization Remote compiling Build cache KSP vs APT Grade daemons
23. ⬢ Architecture ⬢ Build time 23 ⬢ Modularization
24. Modularization “ Divide cada problema en tantas partes como sea posible para resolverlo. René Descartes 24
25. Modularization 25 Layers Features
26. Modularization 26 Module 1 Presentation Feature 1 Feature 2 Feature 3 By Layers Module 3 Data Feature 1 Feature 2 Feature 3 Module 2 Domain Feature 1 Feature 2 Feature 3
27. Modularization 27 Module 1 Feature 1 Presentation Domain Data By Features Module 3 Feature 3 Presentation Domain Data Module 2 Feature 2 Presentation Domain Data
28. Modularization 28 VS Scalability Speed Simplicity Separation of concerns Independency Less conflicts
29. ⬢ Architecture ⬢ Build time ⬢ Modularization ⬢ Design System 29
30. Design System 30 “ Esto es un hecho: no se puede innovar en productos sin primero innovar en la forma en la que se los crea. Alex Schleifer
31. Design System 31 Atomic Design
32. ⬢ Architecture ⬢ Build time ⬢ Modularization ⬢ Design System 32 ⬢ Release Process
33. Release Process 33
34. Release Process 34 “ A medida que las máquinas se vuelven cada vez más eficientes y perfectas, queda claro que la grandeza del ser humano es la imperfección. Ernst Fischer
35. Release Process 35 Bugs Reduce effort (Feature flags, tests A/B, Developer Settings) Automation (Compilation, run tests, artifacts generation, publishing, transitioning tickets..) Release frequently Time
36. ⬢ Design System ⬢ Release Process ⬢ Metrics ⬢ Architecture ⬢ Build time ⬢ Modularization 36
37. Metrics 37 “ Si no podés medir algo, no podés entenderlo. Si no podés entenderlo, no podés controlarlo. Si no podés controlarlo, no podés mejorarlo. H. James Harrington
38. Metrics 38 Development (Errors, time-to-render, API-calls) Business (Not finish payment, not accept newsletter...) User Experience (Time-to-interact, Performance for A/B Testing)
39. Metrics 39 Detect fast Fail fast Alerts Think about business
