The making of Falcon Pro 3 Joaquim Verges - @joenrv
THE CHALLENGE
GEAR UP
COMBO! Retrofit + Jackson/Gson + ORM =
START CODING Multi Activity vs single Activity Back stack? →
new activity! Inside one activity → reusable fragment(s) Notif Notif / Intent filter Notif / Intent filter
CACHING: ORMLite vs Realm ORMLite SQLite based. full java, open
source Realm TightDB based. Closed source C++ core, open source java bindings
OrmLite Realm
Writes in OrmLite
Writes in Realm
Queries in OrmLite
Queries in Realm
Query performance
THREADING AsyncTasks are fine but… could be better:
UI RecyclerView or ListView ? Definetly RecyclerView. Slightly annoying API,
but worth it.
THE BAD: API FAIL Oh google… ListView : 3,905 lines
of code + 7,314 lines in AbsListView RecyclerView : One giant class with 8,427 lines of code Requires work to port from listview
THE GOOD: - free, extensible insert/remove animations - handles position
changes much better - default implementation performs well
ANIMATIONS • Activity Transitions • Shared elements
ANIMATIONS • Layout Transitions • AnimUtils
60 FPS OR NOTHING
RECIPE FOR 60 FPS SCROLLING DONT DO THIS • Deep
view hierarchy • Allocations on critical path • Overdraw USE THE PROVIDED TOOLS • GPU rendering profiling • Tracer for OpenGL • Memory Monitor • Allocation tracker
PROFILING GPU RENDERING GOOD NOT GOOD
DESIGN • sketching • coolors.co • icons https://github.com/konifar/android-material-design-icon-generator-plugin
DESIGN FONTWEIGHTS android:font_family ABC regular ABC light ABC slab ABC
condensed
DESIGN Content first Polish and details
CRASH REPORTING & ANALYTICS Crashlytics + Answers • just the
metrics you need • solid crash reporting tool only downside: • no custom events
SECURITY Paid app? be careful • Proguard • LVL is
over hacked • IAP > paid app • custom server logic
BETA lessons learned from private BETAs with Google+ communities: Don’t
do it. Go public.
PUBLISH The poor’s man marketing material: • video: adb shell
screenrecord • simple banner • framed screenshots • launcher icon
RELEASE EARLY & ITERATE Release too early ? Maybe :)
RELEASE EARLY & ITERATE User driven development! • lets the
users feel like they’re part of the project. • automatic todo list & great engagement. • fix a user’s problem, he becomes your best customer
WAS IT WORTH IT?
YOU CAN DO IT TOO!
