1. Download the WebRTC SDK for Android

To download the Kinesis Video Streams WebRTC SDK in Android, run the following command:

git clone https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-android.git

2. Create a user pool

Setup user pool for secure login using Cognito:

• Go to https://console.aws.amazon.com/cognito/
• Click Manage User Pools
• Click Create a user pool
• Fill-in Pool name

    {
        "Version": "2012-10-17",
        "Statement": [
          {
            "Effect": "Allow",
            "Action": [
              "cognito-identity:*",
              "kinesisvideo:*"
            ],
            "Resource": [
              "*"
            ]
          }
        ]
      }

• Click Allow
• Copy the Identity Pool Id from the code snippets on the screen.

4. Build and run the demo application using Android Studio

1. Import the downloaded SDK into the Android Studio integrated development environment by opening the amazon-kinesis-video-streams-webrtc-sdkandroid/build.gradle with Open an existing Android Studio project.
2. You will need all the information from the above steps copied in clipboard, then paste them into this file on your local file awsconfiguration.json. Your completed awsconfiguration.json should look something like this:

{
 "Version": "1.0",
 "CredentialsProvider": {
   "CognitoIdentity": {
     "Default": {
       "PoolId": "us-west-2:01234567-89ab-cdef-0123-456789abcdef",
       "Region": "us-west-2"
     }
   }
 },
 "IdentityManager": {
   "Default": {}
 },
 "CognitoUserPool": {
   "Default": {
     "AppClientSecret": "abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmno",
     "AppClientId": "0123456789abcdefghijklmnop",
     "PoolId": "us-west-2_qRsTuVwXy",
     "Region": "us-west-2"
   }
 }
}

4. Click gradle Sync and Build
5. Run the demo application in simulator or in Android device (connected through USB).

5. Peer to Peer Streaming

On your Android device, open AWSKinesisVideoWebRTCDemoApp and sign up with Create New Account or sign in with existing accounts.

Note: This account information is stored in your Cognito User Pool and is not your AWS Console user name/password.

Once login is successful, you will entering the following channel information to start peer to peer streaming.

1. Enter a channel name: e.g. demo-channel
2. Enter AWS region: e.g. us-west-2
3. Select audio if you would like to send both audio or video data.
4. Optionally, when using it in viewer mode, you can enter a unique Client Id . Client ID is required only if multiple viewers are connected to a channel. This helps channel's master identify respective viewers.

To verify peer to peer streaming, do any of the following setup. In these setup, ensure that the signaling channel name, region, viewer ID, and the AWS account ID are the same.

5.1 Peer to Peer Streaming between two Android device: Master and Viewer

• Start one Android device in master mode for starting a new session. Remote peer will be joining as viewer to this master. There should be only one master for any given channel.
• Use another Android device to connect to the same channel name (started up in the step above as master) in viewer mode; this will connect to an existing session (channel) where a master is connected.
• Verify media showing up in both Android devices.

5.2 Peer to Peer Streaming between Embedded SDK as master and Android device as viewer

• Run Kinesis Video Streams WebRTC embedded SDK in master mode on a camera device.
• Start the Android device in viewer mode - you should be able to check the video (and audio if selected both in embedded SDK) showing up in the Android device from the camera.
• Verify media showing up from the Embedded SDK to the Android.

5.3 Peer to Peer Streaming between Android device as master and Web browser as viewer

• Start one Android device in master mode for starting a new session.
• Start the web browser using the Javascript SDK and start it as viewer.
• Verify media showing up from the Android device to the browser.
