                    selectedImagePath = getPath(selectedImageUri);
                    Toast.makeText(this,selectedImagePath,Toast.LENGTH_SHORT).show();
                    Log.i("selectedImagePath",selectedImagePath.trim());

From your log it looks like you are trying to pick an image from Picasa folder dat=content://com.android.sec.gallery3d.provider/picasa/item/5147009501910019474, and these must be handled differently, because data in MediaStore.Images.Media.DATA column will be null for them. You can see how to handle picking images from Picasa correctly at this link:

http://dimitar.me/how-to-get-picasa-images-using-the-image-picker-on-android-devices-running-any-os-version/

Only you also need to handle URIs that start with "content://com.sec.android.gallery3d" (I see this on Samsung S3) so change

if (selectedImage.toString().startsWith("content://com.google.android.gallery3d"))

to

if (_selectedImage.toString().startsWith("content://com.google.android.gallery3d") 
    || selectedImage.toString().startsWith("content://com.sec.android.gallery3d"))

I'm not sure if there are any more special cases (probably yes).
