Demo for the talk at DroidconIN 2016

Rxify

Started with a simple demo for the talk at droidconIN 2016, Banglore. Will keep adding more demos and new things here :)

Project Structure

This project :

• Uses RxJava2 for the demos.
• Follows the MVP architecture inspired by repository.
• Makes use of Dagger2
• Uses [Butterknife] (http://jakewharton.github.io/butterknife/)
• Uses TestScheduler for writing tests.

Zip-yosa (ZipActivity)

Perform API calls asynchronously and wait for the result of both the calls to combine the result. For more information, checkout this article.

• We are waiting for FluxWeed API call.

• We are also waiting for Student API call to get hair of Crab.

• Both the calls executing asynchronously.

• Problem :

  • Initialise PolyJuice from the results of API calls.
  • Hide the loader after both calls have completed.

  Here's the demo :

  

Preserving Order in AutoComplete-Search (LibraryActivity)

Depicting the problem of Ordering the results in Auto-Search and solving it using concatMap(). For more information, checkout this [article] (https://medium.com/@ragdroid/rxify-maintaining-order-in-auto-complete-search-d5c46ba26578#.f367qiy0u)

• Perform Auto-Complete Search using flatMap() - results in unordered results
• Toggle state to fix it using concatMap()
• used BookDataSource and calling getBooks(query) on the data source return the results after a delay which is inversely proportional to the length of query string. - this is done to depict the ordering problem
• used the open-source library used at my current company Fueled - [reclaim] (https://github.com/Fueled/reclaim) which extracts the boiler plate for creation of recyclerview adapter, implementation of MVP for listview items.

Using flatMap() - Order is not maintained.

Using concatMap() - Order is maintained.

Ordering problem is fixed, but we shouldn't be updating the list this frequently. switchMap() will improve the results even further :

Using switchMap() - Order is maintained.

TO-DO

• Implement more demos.
