Initialize Meeting - Android

To configure a VideoSDK meeting you require two things, first the token which will be used for Authentication purpose and a meetingId which will be used to specify where a participant will join. Let's see each of the steps closely.

Generating Token

You can generate a token in two ways:

  1. Temporary Token : You can visit Dashboard's API Key section and generate the temporary token from there.

  2. Server : You can setup JWT in backend and make an API call to get the token from your server.

To learn more about Authentication and token in detail you can follow this guide.

// With Temporary Token
fun getToken(): String? {
// Update the token here from the VideoSDK dashboard
return "YOUR_TOKEN"
}

// Server
fun getToken(): String? {
val token = arrayOfNulls<String>(1)
AndroidNetworking.get("http://localhost:3000/get-token")
.build()
.getAsJSONObject(object : JSONObjectRequestListener() {
fun onResponse(response: JSONObject) {
try {
token[0] = response.getString("token")
} catch (e: JSONException) {
e.printStackTrace()
}
}

fun onError(anError: ANError) {
anError.printStackTrace()
}
})
return token[0]
}

Generating Meeting Id

With the token ready, we can get the meetingId from the VideoSDK's rooms API.

fun getMeetingId(token: String?): String? {
var meetingId: String? =null;
// We will use VideoSDK rooms API endpoint to create a meetingId
AndroidNetworking.post("https://api.videosdk.live/v2/rooms")
.addHeaders("Authorization", token) // We will pass the token in the headers
.build()
.getAsJSONObject(object : JSONObjectRequestListener() {
fun onResponse(response: JSONObject) {
try {
meetingId = response.getString("roomId")
} catch (e: Exception) {
e.printStackTrace()
}
}

fun onError(anError: ANError) {
anError.printStackTrace()
}
})
//we will return the meetingId which we got from the response of the api
return meetingId
}
tip

To perform Network call you need to add Fast Android Networking Library in your application.

Initialization of Meeting

  1. To initialize the meeting, first we have to initialize the VideoSDK. We can initialize the VideoSDK using initialize() method provided by the SDK.
initialize
  VideoSDK.initialize(Context context)
  1. Next, we have to set token property of VideoSDK class. By using config() method, you can set the token property of VideoSDK class.
config
 VideoSDK.config(String token)
  1. Now, we can initialize the meeting using a factory method provided by the SDK called initMeeting().

initMeeting() is responsible for initializing the meeting with the provided configuration, which includes the meetingId, name, participantId and many more.

Let's take a deeper look at the available configuration options first.

initMeeting
  VideoSDK.initMeeting(
Context context, // context of activity
String meetingId, // id of meeting
String name, // name of participant
boolean micEnabled, // flag to enable-mic
boolean webcamEnabled, // flag to enable-webcam
String participantId, // id of participant
String mode, // mode of participant
boolean multiStream, // multiStream
Map<String, CustomStreamTrack> customTracks, // map of customTracks
JSONObject metaData // metaData
)
  • context :

    • Context of activity.
    • It will accept Context type value.
  • meetingId :

    • meetingId is unique identifiers that allow participants to join a specific meeting or room.
    • It will accept String type value.
    • It will be in the format of xxx-yyy-zzz and will be generated using the VideoSDK's Room API.
  • name:

    • This will represent the name of the participant in the meeting.
    • It will accept String type value.
  • micEnabled:

    • This is a boolean flag, indicating whether a participant's microphone will be automatically enabled when they join a meeting.
  • webcamEnabled:

    • This is a boolean flag, indicating whether a participant's webcam will be automatically enabled when they join a meeting.
  • participantId:

    • This will be the unique identifier for the participant inside the meeting.
    • It can be used to specify the unique identifier which can be linked with your own database service.
    • It has to be of String type.
    • If you passed null then by default VideoSDK will generate unique id for each participant.
caution

You must ensure that the participantId is not repeated in the same meeting or room, It will enable VideoSDK to eliminate any participant respect to that participantId.

  • mode:

    • There are 2 types of modes:

      1. CONFERENCE : Both audio and video streams will be produced and consumed in this mode.

      2. VIEWER : Audio and video streams will not be produced or consumed in this mode.

    • It has to be of String type.

    • If you passed null then by default VideoSDK will set CONFERENCE mode.

  • multiStream:

    • It will specifiy if the stream should send multiple resolution layers or single resolution layer.

    • It has to be of boolean type.

  • customTracks:

    • If you want to set the initial custom tracks, then you can pass map of custom tracks in this paramater.

    • It has to be of Map<String, CustomStreamTrack> type.

  • metaData:

    • If you want to provide additional details about a user joining a meeting, such as their profile image, you can pass that information in this parameter.

    • It has to be of JsonObject type.

With all the configuration options explained, here is how you can initialize the meeting.

class MainActivity : AppCompatActivity() {

fun getToken(): String? {
...
}

fun getMeetingId(token: String?): String? {
...
}

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)

// initialize AndroidNetworking to perform Network call
AndroidNetworking.initialize(applicationContext)

//We will fetch token and meetingId and store it in local variables
val token: String = getToken()
val meetingId = getMeetingId(token)

// initialize the VideoSDK
VideoSDK.initialize(this@MainActivity)

// set token property of VideoSDK
VideoSDK.config(token)

// create a new meeting instance
val meeting: Meeting = VideoSDK.initMeeting(
this@MainActivity, meetingId, "NAME HERE",
true, true, null, null, false, null, null
)

Log.d("VideoSDK", "onCreate: $meetingId")
}
}
