I all !
I have to do a simple APPs that establish an audio connection beetween two android devices over WIFI.
The calling device is in England and the receiver is in France.
We have no possibility of GSM connection, only WIFI throught internet.
I thought about SKYPE or WHATSAPP that allow those king of connections.
I tryed to use the Skype library with the given exemple and I have an error each time I try to start a connection, saying there is a null object reference?
It's seems that the internal library list is empty, I don't know. If any one can help
the apps is in the zip file ...
The error message :
Error occurred on line: 97 (Main)
java.lang.NullPointerException: Attempt to read from field 'java.lang.ref.WeakReference anywheresoftware.b4a.BA$SharedProcessBA.activityBA' on a null object reference
