Hello,

I set up a sample app to stream the current camera view from my android device to the wowza streaming engine but somehow it does not work.

If I run the app, the app show the camera view and if I try to open the rtmp stream inside the streaming engine I get a status of streaming but the window keeps being black.

I posted the same question on stackoverflow if anyone is interested to answer there aswell.  
[https://stackoverflow.com/questions/45215279/libstream-connection-to-wowza-fails](https://stackoverflow.com/questions/45215279/libstream-connection-to-wowza-fails)

The RTMP shows 100% see images.

I am not sure if I should post my java code here, but if anyone wants to have a look at it click on the link to stackoverflow I put the whole source code there.

Hello @Umut Tufanoglu,

Go ahead and check that your Wowza Engine is configured correctly first.

Are you able to stream with the GoCoder application from your Android Device?

If this works, then the issue is with your code.

You can post or move this post to our [Dev Dojo section](https://www.wowza.com/community/spaces/33/index.html) for more visibility on the question.

Regards,

Alex C.
