Android library (AAR). Highly configurable, easily extendable deep zoom view for displaying huge images without loss of detail. Perfect for photo galleries, maps, building plans etc. A custom image view for Android, designed for photo galleries and displaying huge images (e.g. maps and building plans) without OutOfMemoryErrors. Includes pinch to zoom, panning, rotation and animation support, and allows easy extension so you can add your own overlays and touch event detection. The view optionally uses subsampling and tiles to support very large images - a low resolution base layer is loaded and as you zoom in, it is overlaid with smaller high resolution tiles for the visible area. This avoids holding too much data in memory. It's ideal for displaying large images while allowing you to zoom in to the high resolution details. You can disable tiling for smaller images and when displaying a bitmap object.

ZXing Android Embedded is a barcode scanning library for Android, using ZXing for decoding. The project is loosely based on the ZXing Android Barcode Scanner application but is not affiliated with the official ZXing project. By default, only SDK 24+ will work, even though the library specifies 19 as the minimum version. For SDK versions 19+, one of the changes changes below are required. Some older SDK versions below 19 may work, but this is not tested or supported. While this is not the primary purpose of this library, it does include basic support for generating some barcode types. To change the orientation, specify the orientation in your AndroidManifest.xml and let the ManifestMerger to update the Activity's definition. The camera permission is required for barcode scanning to function. It is automatically included as part of the library. On Android 6 it is requested at runtime when the barcode scanner is first opened.

TIFF codec library on android platform. Porting libtiff library and jni library java API and a demo program of tiff viewer.

We develop lots of different Android apps at Yalantis, and our experience shows that almost every application we deal with needs image cropping functionality. Image cropping can be used for various purposes, from ordinary adjustment of user profile images to more complex features that involve aspect ratio cropping and flexible image transformations. Since we want to provide all our customers with the best set of tools for image editing functionality, we decided to create uCrop, an image cropping library for Android. You might be wondering why we couldn’t just use one of the existing solutions for image cropping for Android. After all, you can find lots of them on Github and on the Android Arsenal. But here is the thing, none of these solutions could satisfy our requirements. Let’s take a quick look at the most popular open-source image cropping libraries and explain why they don’t quite fit the bill.
