Hello everybody!
I'm trying to setup an ImageTarget in runtime with an image I get in runtime (user takes a photo, I cut a Texture2D from the photo). Are there no way to assign a Texture2D or bytes[], which I can get from this Texture2D, to a target? Do I have to save it in the storage of my Android anyway? Could anybody, please, give me a hint or - better - an example of how to solve it best way? If I have to save the texture, where should I save it on Android and how do I get it back, by which path, when I do "ImageTargetBehaviour().SetupWithImage()"? Thank you in advance

Well, it turns out that saving an img to some storage before making a makrer of it is unavoidable in EasyAR, that's a shame... So I had to use absolute paths in my quick and dirty prototype.

You can use an absolute path to create a target.

Check this guide, there says that it can be done at runtime:

Also, check the method of the file at the HelloAr Sample Project:

private void loadFromImage(ImageTracker tracker, String path)

It creates a json at runtime.
