Failed to join session on Android

Video SDK Flutter
,
1

We are trying the example coming with ZOOM flutter Video SDK 1.7.0

The example app works fine on Android emulator.

However, it fails to join session on a real Android phone with following error：
D/ZoomVideoSdkDebug(16138): onError, error: ZoomVideoSDKError_Session_Join_Failed

There is no more hint about why session join failed from log.

Could Zoom dev team please help?

@su.jinyan0 ,

could you try replacing this section of the code in example/lib/utils/jwt.dart?
I’ve

  • shifted the iat (start time) to 5 mins earlier
  • made the exp (expiry) more precise

String generateJwt(String sessionName, String roleType) {
  try {
    var iat = DateTime.now().add(Duration(minutes: -5));
    var exp = iat.add(Duration(days: 2));
    final jwt = JWT(
      {
        'app_key': configs["ZOOM_SDK_KEY"],
        'version': 1,
        'user_identity': makeId(10),
        'iat': (iat.millisecondsSinceEpoch / 1000).round(),
        'exp': (exp.millisecondsSinceEpoch / 1000).round(),
        'tpc': sessionName,
        'role_type': int.parse(roleType),
        'cloud_recording_option': 1,
      },
    );
    var token = jwt.sign(SecretKey(configs["ZOOM_SDK_SECRET"]));
    return token;
  } catch (e) {
    print(e);
    return '';
  }
}
