ITMGContext | Core APIs |
ITMGPTT | Voice messaging and speech-to-text APIs |
Init
API before you can use the voice chat and speech-to-text services.Init
API before calling any APIs of GME.API | Description |
Init | Initializes GME. |
Poll | Triggers an event callback. |
Pause | Pauses the system. |
Resume | Resumes the system. |
Uninit | Uninitializes GME. |
UnInit
to uninitialize the SDK. No fee is incurred for calling Init API.ITMGContext

Parameter | Type | Description |
sdkAppId | String | |
openId | String | OpenId can only be in Int64 type, which is passed in after being converted to a string. |
Returned Value | Description |

Poll
API in update
. The Poll
API should be called periodically for GME to trigger event callbacks; otherwise, the entire SDK service will run exceptionally.
You can refer to the EnginePollHelper.java
file in the demo.Poll
API must be called periodically and in the main thread to avoid abnormal API callbacks.public abstract int Poll();
private Handler mhandler = new Handler();private Runnable mRunnable = new Runnable() {@Overridepublic void run() {if (s_pollEnabled) {if (ITMGContext.GetInstance(null) != null)ITMGContext.GetInstance(null).Poll();}mhandler.postDelayed(mRunnable, 33);}};
Pause
event occurs in the system, the engine should also be notified for pause.
If you need to pause the audio when switching to the background, you can call the Pause
API in the listening code used to switch to the background, and call the Resume
API in the listening event used to resume the foreground.public abstract int Pause();
Resume
event occurs in the system, the engine should also be notified for resumption. The Resume
API only supports resuming voice chat.public abstract int Resume();
