Image Manipulation with facebook login

I need a small android application developed in android studio to do the following: In MainActivity i need only one button (Facebook Login Button) and when user logins with my app, must get users name, surname, email, and users facebook image and one random friend's facebook image and name. After this function in next activity an overlay with a loadin indicator will appeared while finish the following: iSo far in this activity we have thre images (user's image, user's friend image and one image as background image) 1. I need to set custom width and height for 2 images (user's and user's friend image) 2. i need to put these two images at specific position over my background image. 3. the background image will be transparent... so we need a small function to set these images uppfront of my bg image or backward of my background image. The final step is to merge all these 3 images as a jpg image and upload it to my server. When upload is complete the new image url will return to my app, loading indicator will fade out and user can see the new merged image.
