Determining Camera Resolution (i.e. Megapixels) Programmatically in Android

Question

I am developing an Android application in 2.2, which uses Camera. Now Can anyone tell me that \"Is it possible to programmatically determine the Camera Resolution in Megapix

Answer 1

Try this

public float getBackCameraResolutionInMp()
{
    int noOfCameras = Camera.getNumberOfCameras();
    float maxResolution = -1;
    long pixelCount = -1;
    for (int i = 0;i < noOfCameras;i++)
    {
        Camera.CameraInfo cameraInfo = new CameraInfo();
        Camera.getCameraInfo(i, cameraInfo);

        if (cameraInfo.facing == CameraInfo.CAMERA_FACING_BACK)
        {
            Camera camera = Camera.open(i);;
            Camera.Parameters cameraParams = camera.getParameters();
            for (int j = 0;j < cameraParams.getSupportedPictureSizes().size();j++)
            {
                long pixelCountTemp = cameraParams.getSupportedPictureSizes().get(j).width * cameraParams.getSupportedPictureSizes().get(j).height; // Just changed i to j in this loop
                if (pixelCountTemp > pixelCount)
                {
                    pixelCount = pixelCountTemp;
                    maxResolution = ((float)pixelCountTemp) / (1024000.0f);
                }
            }

            camera.release();
        }
    }

    return maxResolution;
}
