Giphy Trending

This sample Android app presents the Giphy trending animated gifs for sharing or download. You can now also search animated gifs by keyword. It was elaborated from the work by Fahri Can in Nov 2021. I migrated the codebase from RxJava to Coroutines, and then from XML Views to Jetpack Compose. The current release is completely different from the original version after these years.

 

The original XML View version

The XML View version is no longer being maintained. You can check out the XML View version branch for that. It was using XML with Data-binding, which we generally believe it to be a bad coding practice by tightly coupling the business logic with the UI.

 

 

Binaries download

If you want to try out the app without building it, check out the Releases section where you can find the APK and App Bundles for each major version. A working Giphy API key was applied when building the app, therefore you can test it by just installing it.

Building the App

Requirements

• To build the app by yourself, you need your own Giphy API Key

 

Setting up the keystore

Release builds will be signed if either the keystore file or environment variables are set. Otherwise, the app will be built unsigned and without the Giphy API key installed, which will not pull any data from the endpoint.

Local

• Android Keystore is not being stored in this repository. You need your own Keystore to generate the apk / App Bundle

• If your project folder is at /app/giphy-trending/, the Keystore file and keystore.properties should be placed at /app/

• The format of keystore.properties is:

     store=/app/release-key.keystore
     alias=<alias>
     pass=<alias password>
     storePass=<keystore password>
     giphyApiKey="<your API Key here>"
  

CI environment

• This project has been configured to support automated CI builds.

• The following environment variables have been set to provide the keystore:

     BITRISE = true
     HOME = <the home directory of the bitrise environment>
     BITRISEIO_ANDROID_KEYSTORE_PASSWORD = <your keystore password>
     BITRISEIO_ANDROID_KEYSTORE_ALIAS = <your keystore alias>
     BITRISEIO_ANDROID_KEYSTORE_PRIVATE_KEY_PASSWORD = <your keystore private key password>
     GIPHYAPIKEY= <your API Key>
  

Build and install on the connected device

This app has two build variants: Debug and Release. The most common build commands are:

• ./gradlew clean installDebug
• ./gradlew clean instal
• ./gradlew clean bundleRelease
• ./gradlew clean assembleRelease

The generated apk(s) will be stored under app/build/outputs/
