This document describes how to use the GME Native Sample Code.
Basic Process Table
The voice chat UI in Sample Code is as shown below (in the demo for iOS):
The following steps apply to all platforms:
Step
Button Name
Feature
1
Init
Initializes SDK
2
Enterroom
Enters the audio room whose room number is specified by RoomID
3
Capture
Enables capture device
4
Send
Enables audio upstreaming (then, audio can be sent and users in the same room can receive the voice chat audio)
5
Play
Enables playback device
6
Rec
Enables audio downstreaming (if another user in the same room has upstreaming audio at the same time, you can hear the corresponding voice chat audio)
7
ExitRoom
Exits room (then, you cannot hear other users' audio nor send your audio to them)
8
Uninit
Uninitializes SDK and completely exits GME
Note：
As steps 3 and 5 are performed at the hardware level, they will take some time to complete.
Only after steps 3 and 4 are completed can audio be upstreamed. Similarly, audio can be played back only after steps 5 and 6 are completed.
Directions
1. Set the account and openID
Note：
You can skip this step and use the test account provided by GME by default.
Before initializing the SDK, modify the Appid, Key, and OpenID parameters on the voice chat UI and click Init.
For the source of the Appid and Key parameters, please see Access Guide.
The OpenID parameter is used to identify the local user, and its value must be above 10,000.
2. Click Init
After setting the account and openID, click "Init" to initialize the SDK. You can perform other operations after initialization.
3. Click EnterRoom
Click "EnterRoom" to enter a desired voice chat room. You can manipulate the devices only after room entry. RoomId specifies the ID of the room to be entered. Only users under the same room ID can talk to each other.
4. Manipulate devices
Manipulate the devices. If there are other users in the room, you can communicate with them.
During the test, you can use another device with the same Appid and different OpenID to enter the same room. After enabling the mic and speaker, your two devices can communicate with each other.
Button Name

Capture
Enables capture device
Send
Enables audio upstreaming (then, audio can be sent and users in the same room can receive the voice chat audio)
Play

Advanced Operations
Changing room audio type
Before room entry, you can select the audio type. For more information on the effects, please see Sound Quality Selection.
After room entry, you can click ChangeRoomType to change the room audio type.
Setting volume level
You can drag the slider to set the volume level after room entry.
The left slider is used to set the capture device volume level, which determines the volume level of the captured audio.
The right slider is used to set the playback device volume level, which determines the volume level of the audio played back.
Enabling/Disabling in-ear monitoring
You can click the button next to "Loopback" to enable/disable in-ear monitoring. If it is enabled, you will be able to hear your own voice from the playback device.
Setting accompaniment
After entering the room and performing steps 3, 4, 5, and 6, you can click the button next to "Accomp" to enable other users in the same room to hear your accompaniment. If in-ear monitoring is enabled, you can also hear your accompaniment.
