I set the preview frame rate to the lowest rate possible with this code, but you could set it to the highest rate possible by using l_last instead of l_first in the List index (mCamera is a member variable that references the Camera and is set elsewhere in the code).

Camera.Parameters l_params = mCamera.getParameters();

List<int[]> frameRates = l_params.getSupportedPreviewFpsRange();
int l_first = 0;
int l_last = frameRates.size() - 1;
int minFps = (frameRates.get(l_first))[Camera.Parameters.PREVIEW_FPS_MIN_INDEX];
int maxFps = (frameRates.get(l_first))[Camera.Parameters.PREVIEW_FPS_MAX_INDEX];
l_params.setPreviewFpsRange(minFps, maxFps);

mCamera.setParameters(l_params);

You can use public List<int[]> getSupportedPreviewFpsRange () to check what FPS range supported by your device. Here is mine:

preview-fps-range-values=(10000,10000),(15000,15000),(15000,30000),(30000,30000);

so if I want to change the fps to 15, I can setPreviewFpsRange(15000,15000).
