An app for catching up on things.
There's a lot of services I like reading up on throughout the day. Most of these services have dedicated apps for consuming them, but often times I just want to skim the front page and only deep dive occasionally. Enter CatchUp: a high level presentation of the "front page" of several services in short form, and intelligent deeplinking into dedicated apps if you want to go further.
CatchUp is not an all-purpose client for each of these services, just the concierge for at-a-glance details and router for getting on your way. It does not support login for any service, it does not support customization/filtering of their feed. CatchUp is dumb, and you should use one of the many great dedicated apps for this if you want more integration features.
CatchUp is also very much a testing ground for things I personally dive into, from architecture, libraries, patterns, API quirks, and more. It's been a very fun project to spike test new things.
- Multiple services
- Hacker News
- Product Hunt
- Designer News
- Infinite scrolling on supported services
- Pleasant, simple, consistent UI for across services
- Night mode
- Smart deeplinking into dedicated apps
- RxJava 2/AutoDispose
- Debugging tooling as a first class citizen in the debug build
- Leak Canary, Chuck, Scalpel, debug drawer, Stetho, bug reporting, the works
- Dagger 2
- One of the more interesting parts of CatchUp is that its service architecture is a Dagger-powered plugin system
- Room (Arch components)
- AutoValue + extensions
- Apollo GraphQL
- Standard Square buffet of Okio/OkHttp 3/Retrofit 2/Moshi
There's a lot of neat/interesting little tidbits in the CatchUp source code that I plan to write a mini blog series about. Each service has its own nuances that make them unique to work with in code.
While this is a personal pet project, extensive tests can be found here.
This app owes a lot of its inspiration, implementation details, and general inner workings to the work of others. Particularly:
CatchUp is in open alpha, but master tends to be rather far ahead of what's on the Play Store.
If you'd like to build CatchUp locally, you should be able to just clone and build with no issues.
CatchUp tends to keep up with Android Studio canaries, so you may have to use a canary version.
Check the Android Gradle Plugin
deps.android.gradlePlugin dependency in
If you want to build with working services, some require API keys. See the wiki for more details on which services require keys.
Bug fixes are always welcome. Tests are too if you're into that kinda thing, but I'm not actively trying to make this project a shining icon of TDD. For new features or otherwise significant work, please discuss in an issue first.
Note that by default, I have a Timber tree that crashes the app in the event of an error in debug
(fix me now!). This may be problematic if you don't have services authenticated (especially Firebase
and its ever shifting requirements), so you can disable this behavior via setting the
property in the root
gradle.properties file to
For apollo-android's code generation: if you want to use a local installation of the
node module you'll need to make sure
0.19. is installed and linked (
npm install -g email@example.com). Otherwise,
the gradle plugin should gracefully fallback to downloading it on demand.
