Black screen after join the meeting

shingshing6 · June 19, 2020, 9:45am

Description
May I know what should I do for the black screen? It is ok when using your demo app, however, it appears black screen when integrated into my own app.

ps: normally, it is working as i can hear the sound and speak in the black screen.

Step:

Join the meeting in portrait
Click the “open video icon” without response (still in red color)
Click the screen in the middle. Show black screen as attached.
Make the phone in landscape
Everything resume normal
Make the phone in portrait
Everything resume normal

It seems I need to refresh something in order to make the layout show in a normal way. Do you have any advise?

Which version?
v4.6.21666.0429

Hi @shingshing6,

Thanks for the post. As you have tried as well, I tried to follow your steps with our demo app and everything is working. May I inquire the following:

Is this user join the meeting successfully? If you use other devices to join this meeting, are you able to see this user’s video and info well? (If yes, then it will be just a local video view presenting issue, otherwise, it might be an issue that this user is not able to join the meeting)
Could you share any code snippet or SDK log for us to further investigate?

Thanks!

Dear Carson,

Please find the log in the below link:

log

The user can join the meeting successfully as i mentioned before, just the screen is black. It seems the audio is ok but video is fail.
Coding:

MyActivity.java:
public class MyActivity extends Activity implements InitAuthSDKCallback,
MeetingServiceListener, UserLoginCallback.ZoomDemoAuthenticationListener {

private final static String TAG = "ZoomSDKExample";

private View layoutJoin;
private View mProgressPanel;
private ZoomSDK mZoomSDK;

private String meeting_id = "";
private String meeting_pw = "";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Bundle extras = getIntent().getExtras();

    meeting_id = meeting_id;
    meeting_pw = meeting_pw;

    mZoomSDK = ZoomSDK.getInstance();
    if (mZoomSDK.isLoggedIn()) {
        finish();
        return;
    }

    setContentView(R.layout.init_auth_sdk);

    mProgressPanel = (View) findViewById(R.id.progressPanel);

    layoutJoin = findViewById(R.id.layout_join);
    mProgressPanel.setVisibility(View.VISIBLE);

    JSONObject jObj = new JSONObject();
    try {
        jObj.put("jwtToken","JWTTOKEN");
    } catch (JSONException e) {
        e.printStackTrace();
    }

    InitAuthSDKHelper.getInstance().initSDK(this, this, jObj);

    if (mZoomSDK.isInitialized()) {
        layoutJoin.setVisibility(View.INVISIBLE);
        ZoomSDK.getInstance().getMeetingService().addListener(this);
        ZoomSDK.getInstance().getMeetingSettingsHelper().enable720p(true);

        onClickJoin();
    } else {
        layoutJoin.setVisibility(View.GONE);
    }
}

@Override
public void onZoomSDKInitializeResult(int errorCode, int internalErrorCode) {
    Log.i(TAG, "onZoomSDKInitializeResult, errorCode=" + errorCode + ", internalErrorCode=" + internalErrorCode);

    if (errorCode != ZoomError.ZOOM_ERROR_SUCCESS) {
        Toast.makeText(this, R.string.fail_init_zoom, Toast.LENGTH_LONG).show();
        finish();
    } else {

    }

@Override

@Override

        mZoomSDK.logoutZoom();

public void onClickJoin() {

    Context context = getApplicationContext();

    Intent intent = new Intent(context, MyMeetingActivity.class);
    Bundle bundle = new Bundle();
    bundle.putString("meeting_id",meeting_id);

@Override

    Log.d(TAG,"onMeetingStatusChanged "+meetingStatus);
    if(!ZoomSDK.getInstance().isInitialized()){
        showProgressPanel(false);
        return;
    }

    if (meetingStatus == MeetingStatus.MEETING_STATUS_DISCONNECTING){
        finish();
    }
}

@Override
public void onDestroy() {
    super.onDestroy();
    UserLoginCallback.getInstance().removeListener(this);

    if(null!= ZoomSDK.getInstance().getMeetingService()){
        ZoomSDK.getInstance().getMeetingService().removeListener(this);
    }
    InitAuthSDKHelper.getInstance().reset();

MyMeetingActivity:

    super.onCreate(savedInstanceState);

    Bundle extras = getIntent().getExtras();

        JoinMeetingParams params = new JoinMeetingParams();

        params.meetingNo = meeting_id;
        params.password = meeting_pw;

        JoinMeetingOptions opts = new JoinMeetingOptions();
        opts.no_invite = true;

        ZoomSDK.getInstance().getMeetingService().joinMeetingWithParams(this, params,opts);

        ZoomSDK.getInstance().getMeetingSettingsHelper().enable720p(true);
    } else {
        Toast.makeText(this,"SDK is not ready",Toast.LENGTH_LONG);
    }
}

@Override
public void onBackPressed() {
    onClickLeave();
}

}

Thanks.

Hi @shingshing6,

Thanks for the info. If seems like you are extending the MeetingActivity, so the transition to the meeting UI should be done by SDK. Using context.startActivity(intent) will result in issues. Please add the following to your config.xml and SDK will invoke your activity after successfully start/join the meeting:

<string name="zm_config_conf_activity">packageName.MyMeetingActivity </string>

Hope this helps. Thanks!

shingshing6 · June 26, 2020, 2:58am

Dear Carson,

I have added the code above in config.xml already. However, the issue still happen.
Even though, I added my coding in the demo apps and updated zm_config_conf_activity, it still not working. Please help for it.

Thanks.

carson.zoom · June 27, 2020, 2:36am

Hi @shingshing6,

Let me circle back to the engineering team on this and get back to you shortly. Thx

shingshing6 · June 29, 2020, 2:05am

Dear Carson,

Thanks. Please help for it, I was already struggle it for 3 weeks.

shingshing6 · July 3, 2020, 2:54am

Hi Carson,

May I know is there any update of this issue? Thanks.

carson.zoom · July 3, 2020, 5:46am

Hi @shingshing6,

Thanks for the reply. Is it possible to request an apk of your app with the issue you are facing so that we could experience the issue and troubleshoot it from there? We are not able to reproduce this on our end.

Thanks!

shingshing6 · July 3, 2020, 8:23am

Hi Carson,
Attached the source code for your debug.

Source

Please place the src folder under sample/src. Then, please update your API key, secret and then update your MEETING_ID and MEETING_PW inside the source code.

My workflow is init the SDK and auto join the Zoom via onClickJoinForMyActivity()

Thanks.

shingshing6 · July 8, 2020, 8:12am

Hi Carson,

Any update? Many thanks.

shingshing6 · July 22, 2020, 8:42am

Hello? May I know how to solve this issue?

carson.zoom · July 29, 2020, 11:36am

Hi @shingshing6,

Pardon the late response. Thanks for providing the code, really appreciate it. Unfortunately we are not able to find the issue in your code so we would like to suggest cross-referencing the demo app.

Thanks!

shingshing6 · July 31, 2020, 3:55am

Hi Carson,

Do you mean you will investigate the problem with your technical / development team?

Much thanks.

carson.zoom · August 1, 2020, 4:56am

Hi @shingshing6,

Thanks for the reply. I could work with the dev team on this but since they have very limited bandwidth, so it will take some time to get back to you. It is suggested to cross-referencing the implementation of the demo app so that this issue could get resolved faster.

Thanks

shingshing6 · August 5, 2020, 9:40am

Dear Carson,

Is there any methods to open the Zoom SDK with specific orientation?

PS: Using default UI

Thanks.

carson.zoom · August 8, 2020, 2:07am

Hi @shingshing6,

Thanks for the reply. Unfortunately there is no interface to fix the Zoom SDK with specific orientation in default UI.

Thanks!

shingshing6 · August 8, 2020, 4:10pm

Dear Carson,

Thanks for your reply. Please remind to follow up the previous issue I found. ie: the black screen issue.

Many thanks for your follow up.

shingshing6 · August 19, 2020, 7:26am

Hi Carson,

May I know if I can pass some parameters (other than JoinMeetingParams and JoinMeetingOptions) to CustomZoomUIActivity.java?

eg: I want to pass the age to CustomZoomUIActivity.java

Thanks.

jon.zoom · August 19, 2020, 6:22pm

Hi @shingshing6,

It sounds like you might be looking for Intents, but please correct me if I’m misunderstanding

Thanks!
