Sample Android Code for moving an image behind a selection box

I am looking for a sample code/app that can take a picture with the camera and then have the ability to crop it, specifically using the method of moving/zooming the image behind a selector box like the current google photos editor does.
bonus points if you can find something for xamarin :)
i found this, but i am looking for a more complete example.

Clickable resizable buttons on image android

I am trying to create an application which has a map image in it.
I want to add some areas (or buttons) to it so that when you click them the bubbles with information will appear.
I am new in android programming so asking to explain a bit how to implement it?
Also i need an image to be re-sizable just like a real map.
So should i attach the buttons to specific places on image and how to do so that the buttons will be connected to it when i re-size an image?
Which image type is better to use for this purpose? I heard that SVG would be better but i couldn't even add svg image to an application.
I appreciate any helpful advice.

For your problem you can use this:

I need something similar, but the click on the image should change the content of that part as well.
When I find or implement the final solution I can post it here.

Image Circulation in android

I have created a app to find the hotels, I am using a slider to show all images related to the hotel's. But I want to get the first image after the last slide in circular fashion.
Get idea through below Picture, Because I want to achieve it in same way.
Sliding SlidingSlidingSliding
All image must be in circular fashion with no end point for image in gallery while sliding.

Please have a look at the below library called InfiniteScrollView.
I think this will do exactly what you are looking for.

Android: Making a variable image

I would like to program an image that the user can press which will display another image when touched to give the user more information but then revert to the previous image after the user stops touching the image. I would also like to add vibration and a ding sound (which I have) when the image is touched. I looked into this but found someone else with the same problem who couldn't help - they said only one of the actions was possible. Help?!
Oh, and if you're feeling extra kind.. Is there a way to configure the amount of time the extra info picture stays when the user stops touching the image?
Thanks

Have you tried any coding at all before asking how to do it? Also, rather than asking how to do a whole project you should ask the parts you are having trouble on once you've actually attempted it...

Changing image angle in android gallery view

i want my gallery application to be modified , like coverflow. but not exactly like coverflow. the images in the gallery view should be viewed in such a way that it should look like reverse letter "U" . i want to change the angle image in such a way that it has to go slightly go above the previous image so that i can achieve the reverse "U" for gallery view.

There are already widgets out there that you can consider using. I found one http://www.inter-fuser.com/2010/02/android-coverflow-widget-v2.html that looks very good, but it might not be exactly what you are looking for.
Here is another one based on the interfuser widget. http://code.google.com/p/android-coverflow/.
They claim to have improved the performance of it.
Whether you can use them as is or not, you can probably use the source as inspiration.

You can use preRotate or postRotate methods in android.graphics.Matrix. Check them once.
