I'm looking for a framework or a solution of loading and showing high resolution images on mobile devices where being able of viewing them in their native resolution is compulsory. Scaling is optional.
I'm talking about resolutions reaching over 2000x1000 pixels.
10x for your kind help BR
Without going into much detail you could probably use a TextureRegion with libgdx to display certain parts of your image on the screen.
I even think there's an example on the wiki you could use.
Check out Apple's PhotoScroller example. I have successfully used it with images over 100 megapixels.

I am attempting to Reduce the glare produced when taking a photo or video of a Reflecting surface; Window, Glasses or another Mobile Device.
I have done some research on the subject, and it seems that some algorithms exist. But I am yet to find a coded implementation.
The reason I need this is because I am making an Application that allows you to read different colours on another devices screen using the camera on your device.
And if there is a lot of glare, the colours wont read properly. It needs to be able to distinguish between 16 Colors.
Are there any existing implementations, and if so how would I implement them into Android?
I recommend doing a threshold on top of a gaussian blur to identify bright spots in your image and removing them. OpenCV is the industry standard and your best bet for image manipulation. I recommend doing some experiments on a computer first to get your process flow right first, before moving it onto a phone. Also, stay away from anything too novel/complicated.

I want to make a textView exactly like this.Can anyone help??
You need to create a background image with 9-patch tool, in such a way that the display text would be fit in well and also you need to take care of inner paddings.
Update:
Including my comment about why we can't use simple background image?
We can obviously use the simple background but only when you know the size of device in which your application are going to use "only", but in android no one can be sure about the size as it's coming into the variety of resolutions and display sizes. So if you would want to provide the image compatibility to all the sizes and resolutions then prepare such background using 9-patch tool

please let me share your ideas.
I need to set original width and height of images or video thumbnail from web services in listview dynamically as like facebook,vine application.Please help me to sort out this issue.
I'm novice to image handling.
You can't be sure about the image size would be uploaded by application user. At the same time, you can't be sure about the image size (or device size) you should display into the android device, because android devices are coming into the wide range of resolutions!
If you include more details then I would share more details! But as of now I would say, refer ImageView.ScaleType and decide the scale type you should use for the ImageView.

I must implement an applcation that draws a heart on a person seen via an Android device camera(augmented reality stuff).
So, I must detect the shape/contour of the upper part of human body(head, neck, shoulders) in order to know where the heart must be situated. This stuff must be made in real time.
I've searched about this stuff but I haven't find something useful. Does anybody know some tutorials or examples of something related to this? Thanks.
I would recommend using OpenCV if the memory isn't a problem ( your app would be like 50 MB). There are plenty of tutorials to learn how to use OpenCV. Try Cascade Classifier
In case of face detection, as far as i know, android has a library for this. Camera.Face

I want to do video compression.
Actually in my application I want to have two options, one is low and another is high. If I choose the low option then the application will compress the video and then upload it. If I choose high then it will upload the original video which I have recorded itself.
I want to do this thing in my application and I'm confused. I have searched google a lot but I'm not able to find the useful way to solve this question please if anyone can help me out.
I used ffmpeg4android,
And was able to achieve this in about 10min using only java,
