we are developing an android app in android studio. The app should be able to connect to our Cloud Database and get the targets.
We've tried to connect to our Cloud Database like shown in the sample https://developer.vuforia.com/downloads/samples#downloadModal. Unfortunately the response code of the HttpURLConnection is 401.
Because some functions of the samples are deprecated in java, we've tried to build the signature by ourself. So we guess that the creation of our signature isn't right.
Please see attached our .txt-file, can you see what we do wrong?
