DevGrid

Implementation Steps

I followed the steps below:

1. Create repo on Github.
2. Include basic dependencies in Gradle: Dagger2, Retrofit and RecyclerView.
3. Customize file gradle.properties.
4. Add MVP pattern.
5. Import classes to perform basic Retrofit call.
6. Add Retrofit Interceptors: Cache, NetworkInterceptor and OfflineInterceptor.
7. Add Timber.
8. Test basic Retrofit call using the Github API: https://developer.github.com/v3.
9. Create Instrumented Tests to test the app.
10. Create Interceptor to modify Retrofit Header.
11. Implement AndroidX.
12. Create Unit Test to test Login and Password with Base64.
13. Apply MockWebServer on project to perform tests.
14. Implement RxJava on Retrofit calls.
15. Insert Retrofit result in the RecyclerView.
16. Test Retrofit call bringing last 5 commits from each repo.
17. Add NavigationUtils.
18. Add Loading view before data retrieval.
19. Create Unit Test to test take(5) command.
20. Add CardView to Adapters.
21. Read a QrCode and get its link for the Github repo.
22. Create graphic interface requesting User Password.
23. Fix login feature.
24. Update method to check Internet connection.
25. Update DataBinding.
26. Add Pagination.
27. Write README.

Implementation Details

As requested in the project spec:

• The app reads a QrCode with a Github link.
• The app validates this link and informs the user.
• Then, Login screen is opened.
• All the login checks are made.
• If the user perfoms login correctly, a screen is opened, showing its Github repositories.
• Those repositories are showed in a RecyclerView, with its proper Pagination.
• All repositories are showed: Public and Private repos.
• Clicking on each repo, a Details screen is opened, showing the latest 5 commits from this repo.
• Internet connection check was implemented.
• A lot of tests were created on this project, like: Base64 tests; tests to check the .take(5) from RxJava Observables; Network tests using IdlingResource.

Also, this app is using:

• Kotlin
• SOLID and Clean Code principles
• Retrofit
• Dagger 2
• ConstraintLayout
• Espresso Tests
• RxJava 2
• Timber
• RecyclerView
• CardView
