How to setup proguard for media upload

To start uploading media to feed (release mode) - Add Proguard rules using the guide below

Proguard setup

This is required only for Android, when you are building for release mode.

To enable uploading of media in the release build of Android, add these lines in your app/build.gradle

  minifyEnabled true
  useProguard true
  proguardFiles getDefaultProguardFile('proguard-android.txt'),
          'proguard-aws-2.1.5.pro'

  //EXAMPLE
  buildTypes {
    release {
    signingConfig signingConfigs.release
    minifyEnabled true
    useProguard true
    proguardFiles getDefaultProguardFile('proguard-android.txt'),
                  'proguard-aws-2.1.5.pro'
    }
  }

Now create a new file with name "proguard-aws-2.1.5.pro" at the same location as app/build.gradle and paste the copied contents into this file. Paste the content below into this file.

# These options are the minimal options for a functioning application
# using Proguard and the AWS SDK 2.1.5 for Android
