Wowza Player prevent Delay

Hi,

I implemented the Wowza Player successfully. The stream works but the delay is huge.
The delay goes currently can go up to 20seconds.
I am streaming using the Wowza SDK from my android device, currently the app uses the adaptive bitrate configuration with a low resolution(640x480).

It seems like it may happen due the buffering.

An example:

I start the stream from my android device and I start the wowza player in my webapplication.
The stream gets like a default delay of 5 seconds.
If the Wowza player buffers the delay increases.

How can I reduce the delay?
