I am trying to set the frame rate for camera preview and testing it on Nexus S.
The Camera.Parameters.getSupportedPreviewFPSRange for back-facing camera returns 15000 and 30000. and front-facing camera returns 7000 and 30000.

The follwoing code works fine without error for the front facing camera, but for the back-facing camera, it throws a runtime exception in setParameters "java.lang.RunTimeException, setParameters failed. "
Tried it with various values ranging from 15001 to 29999 and no luck.

if(cameraInfo.facing == CameraInfo.CAMERA_FACING_FRONT){
parameters.setPreviewFpsRange(8000, 25000);
parameters.setPreviewFpsRange(16000, 22000);


Eventhough the code for front-facing camera executes without error, the FPS seems to be arounnd 7.5 to 8.3 always irrespective of the value set. Any ideas or suggestions?
It is sorta covered in the JavaRanch Style Guide.
