I was only able to find one previous post regarding this, and the provided answer did not seem to work correctly. Is there ANY way to show a TIFF image with pinch / zoom ability in Android? Writing an app and I need to show a TIFF image.
There appears to be, in fact, a way to display a TIFF image on Android even though that format isn't supported by ImageView.
Take a look at this project.
If you want to show tiff images in your android app but don't want to build native components, look there https://github.com/Beyka/Android-TiffBitmapFactory Is my library for working with tiff.
