Fragmented Podcast Update – TSHIRTS 🐀

We’re extremely excited to announce a brand new T-shirt sale from Fragmented.

Our last run with the Spacedroid was so successful with listeners that we decided to work again with our good friend Taylor Ling for this brand new design.

Taylor’s DroidTee designs have gained legendary fame amongst Android devs and this time he’s made something extra special just for us:

The pragmatic programmers will astutely observe why this design is so close to our hearts. We’re big fans of the Rubber duck approach to debugging and we hope you’ll proudly wear these as you champion on with your development.

The campaign closes April 7th, so please place your order before then. We hope you love the t-shirt as much as we do.

Purchase the t-shirt here!

156: Increase App Engagement with Android Q


Download

With the release of Android Q we now have the settings panel and all its glory. This panel, while most likely overlooked as a minor feature, is actually a diamond in the rough.

Why?

Simply because it’s going to lower the abandonment rate of your app and increase the engagement of your app at the same time. Donn talks about this in depth in this episode.

155: Naming conventions for RxJava Observables

Download

The Android community has come to use Rx pretty heavily but surprisingly there hasn’t been any one convention that’s won, when it comes to how we name our functions that return Observables. getUser(), user(), userUpdates() ? In this mini-episode dutifully does the yak-shaving for you and discusses what some options are and what the community has been gravitating towards.

Enjoy.

Shownotes

Upday’s convention:

Options

// option 1
fun getUser(): Single<User>
// yuck

// option 2
fun user(): Observable<User>
// but what does this mean?

// option 3
fun user(): Single<User>
fun userUpdates(): Observable<User>
// or
fun userStream(): Observable<User>
// this is looking good

// option 4 (upday style)
fun userOnce(): Single<User>
fun userStream(): Observable<User>
fun userOnceAndStream(): Observable<User>

Stay tuned for a future episode, where we discuss more details and more complicated cases to handle (like emitting a list of user, policies for fetching the first user as quickly as possible etc.).
