ApplicationError(wamp.error.invalid_uri, [], {}) even when URI is completely valid #102

Closed cdrandin closed 7 years ago

cdrandin commented 7 years ago

I have tested the process I have been doing on multiple devices, however, when I start using it on Android it always fails.

I have been using WAMP to communicate between multiple devices. There doesn't seem to be any official support for Autobahn on Android that supports WAMP jawampa should do the trick.

I included this module into the Android project using Android Studios. I am rather new to Android development so I tried resolving the issues from places I have more experience in. I think that this is possibly something going wrong when using this with Android.

Here are my settings for the project.

app gradle:

Now that I once again look through the issues I think you have an issue with static initialization order: WampTasks _ourInstance is initialized and the WampTasks() constructor code is called before _host and _port are initialized. Therefore the formatted uri is garbage. Should also be easily checkable in the debugger.
