This is a practical project for an application to Android Software Engineer position. Check all details below
👀
This is a small Android application that emulates operations over a virtual wallet.
This wallet itself can hold Bitcoins(BTC) or Britas(BTA, same as USDs), along with real brazilian currency,Real(BLR).
The solution must leverage pre-defined data sources for broking prices, both for Bitcon and USD dollars, as well emulate an inital giveway scenario for new users.
All this bussiness logic is holded by a dedicated online system, KryptoKarteira, built from scratch for this practical project and with a proper REST API exposed for this client
Finally, this solution relies on several modern approaches to build Android applications
- 100% written in Kotlin
- Offline-first application
- Continuous Integration from the very first commit
- Rock-solid reactive architecture, powered with MVVM + RxJava2 with very unique approach
- Dependency Injection powered by KodeIn
- Massive test coverage, using both local JVM (JUnit and Roboletric) and Instrumentation (Espresso - WIP) test frameworks
- ETC
This application uses
- Android Gradle Plugin 3+
- Kotlin 1.2+
In order to import and runs this project on Android Studio, please check your IDE plugins to meet these requirements.
All the build variants can be built by the straightfoward
./gradlew build
This Gradle tasks will build all the four variants for this project as well run the JVM local tests for all of them.
If you want to run instrumentation tests, you may want to leverage one of the mock
variants of this build, since these variants rely on REST API calls stubbed with
Mockito and properly configured accorded the desired scenario per test.
./gradlew connectedMockDebugAndroidTest
This approach provides hermetic testing conditions for the acceptance tests implemented with Instrumentation/Espresso.
NOTE - You must have an online AVD or Android device to run this task
Any one of the four outputs APKs may be used for manual checking of this solution.
However, note that app-mock-*.apk ones will EVER behave the same way, ignoring
netwoking and assuming all the REST API call as successfull : therefore, you are
not able to verify any error treatments using these artifacts.
In order to check all the full features delivered with this exercise, you must
use one of app-live-*.apk APK artifacts, grabing one APK from
app/build/outputs/apk after the proper assemble Gradle tasks like
./gradlew assembleLive
or installing the APK directly on device, by instance
./gradlew installLiveDebug
I`m glad to awser, just ping me on the internets! 😹
