Question

I am facing issues with getExposureCompensation() and
getExposureCompensationStep() apis. Whenever I call these two apis, it
throws a null pointer exception. When i use the
getExposureCompensation after using setExposureCompensation() api,
then it works fine. But in the case of getExposureCompensationStep(),
i dont have a choice.

Your opinion and suggestion in this matter will be appreciated.

Thanks

EDIT: There’s your problem. 🙂 Or not… >.>

Camera does not have a getExposureCompensation() or getExposureCompensationStep() method. Those are methods for your Camera.Parameters object! Try changing it to:

int expcomp = params.getExposureCompensation();
float expstep = params.getExposureCompensationStep();
