Android:problem on cropping image by camera activity

Question

I have made an App in which I have captured an image from camera and a rectangle is shown to crop the selected area. But I'm facing two big problems in it:

when we change the dimensions of rectangle appeared to large size for cropping the image then instead of showing cropped image file it restart camera activity?while the same thing I have done in taking image from gallery and it is working.
aspect ratio is not working for image taken from camera activity?

Code for camera activity:

public void onClick(DialogInterface dialog, int item)
{
        Intent intent = new Intent();
        intent.putExtra("crop", "true"); 
        intent.putExtra("aspectX", 774);
        intent.putExtra("aspectY", 1115);
        intent.putExtra("outputX", 774);
        intent.putExtra("outputY", 1115);

        if(item==0)
        {
            intent.setAction("android.media.action.IMAGE_CAPTURE");
        startActivityForResult(intent, PICK_FROM_CAMERA);
    }

actually geet i think you should go for startactivityforresult i mean when you click image you should return from the camera activity and the crop image on your old activity. just a suggestion — Abhinav Singh Maurya, Aug 06 '11 at 07:47
problem is when i open the camera its not taking the image in ratio I am selecting — Geetanjali, Aug 06 '11 at 07:52
for that geet you have to override camera functionality and the giving that aspect ration in it — Abhinav Singh Maurya, Aug 06 '11 at 08:41
