Android：通过相机活动裁剪图像的问题

我制作了一个应用程序，其中我从相机捕获了图像，并显示一个矩形来裁剪选定的区域。但我面临两个大问题：

当我们改变矩形的尺寸时，它看起来很大用于裁剪图像，而不是显示裁剪后的图像文件它会重新启动相机活动？而我也做了同样的事情从图库中获取图像并且它正在工作。
长宽比不适用于从相机活动拍摄的图像？

相机活动代码：

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);
    }

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);
    }
