It's funny though, I have just compiled my app (CUtubers) using W2Apk builder Pro version 3.3.3. The external links are working on a Samsung Galaxy s9+ with Android 9, but not working on a Blu Advance 4.0 L2 with Android 6.
This is the code to dynamically generate my links (maybe it shows some problem):
SetVar "[linkVar]" "[DataList.Record.TheAddress]?parameter=1" "String"
It basically creates a var and assigns to it the concatenation of a var and a text.
Then, it uses the API to launch that URL. In fact, I use a YouTube link and YouTube (the app) opens when the link is launched.
Is it me or there's a problem causing this funny behaviour? This is the most important feature of my app and most of my target uses cheap phones. It sets my app close to useless. Any help wanted ASAP.
