Flickr-Finder

Requirement

Create a mobile app that displays photos returned from the Flickr search API.

Technologies used

• Android SDK
• REST API (Consumed through Retrofit2)
• JSON Parsing (GSON)
• Dependency Injection (Dagger Hilt)
• Concurrency (Kotlin Coroutines)
• Image display - Glide
• Navigation - Jetpack - navigation

IDE

• Android Studio Electric Eel | 2022.1.1

Features

• Image search and display 25 images in the screen.
• Image details screen with back navigation feature.

Future Improvements

• Save prior search terms and present them as quick search options

  Possible solutions : According to this app need to clarify the search history requirement. For example, if the search terms should only be stored for the current session and not saved across app launches SharedPreferences or SQLite would be a good option. But if the search terms should be stored permanently, and you want to query them later, SQLite or Room would be a better option.

• Ability to bookmark and view images offline

• Page results (allowing more than the initial 25 to be displayed)

  Possible Solution : Can be accommodate a user input option for user to define how many images per page require and that amount can pass as a parameter to the API call (per_page= AMOUNT).

Notes on API call for testing

Example Postman script for texting the API call

Method: GET URL: https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=YOUR_API_KEY&text=horse&tags=horse&per_page=25&extras=url_o,url_q&format=json&nojsoncallback=1

Headers: None Body: None

Note: Please replace "YOUR_API_KEY" with your own Flickr API key. Also you may want to add some query parameters to the url to filter the returned images.

For example, to filter the images by its license type, you may want to add &license=1,2,3,4,5,6,7,8 to the url.
