Add the below code to Crop the image.Modify your OnActivityResult code , try like this. Hope this may help you.
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
if ((requestCode == PickImageId) && (resultCode == Result.Ok) && (data != null))
{
Android.Net.Uri uri = data.Data;
//Toast.MakeText(this, path, ToastLength.Long).Show();
Toast.MakeText(this, uri.ToString(), ToastLength.Long).Show();
// It will crop the image accordingly.
cropPicture(uri);
string path = GetPathToImage(data.Data);
Toast.MakeText(this, uri.ToString(), ToastLength.Long).Show();
Toast.MakeText(this, path, ToastLength.Long).Show();
}
else if(requestCode == CROP_PIC)
{
// Get your cropped image here using Bundle and save the bitmap in particular location.
}
}
private void cropPicture(Android.Net.Uri picUri)
{
try
{
// call the standard crop action intent (the user device may not
// support it)
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.SetDataAndType(picUri, "image/*");
// set crop properties
cropIntent.PutExtra("crop", "true");
// indicate aspect of desired crop
cropIntent.PutExtra("aspectX", 2);
cropIntent.PutExtra("aspectY", 1);
// indicate output X and Y
cropIntent.PutExtra("outputX", 256);
cropIntent.PutExtra("outputY", 256);
// retrieve data on return
cropIntent.PutExtra("return-data", true);
// start the activity - we handle returning in onActivityResult
StartActivityForResult(cropIntent, CROP_PIC);
}
// respond to users whose devices do not support the crop action
catch (ActivityNotFoundException anfe)
{
Toast toast = Toast
.MakeText(this, "This device doesn't support the crop action!", ToastLength.Long);
toast.Show();
}
}
