have you tried to send a message from the android studio app?
what happens?
the library's intent contains no action. its "extra" is "result_extra_key".
according to android's dox, if an intent has no action, an intent filter need
only list any action in order to qualify to receive the intent. in other words,
the intent does not need an action, but an intent filter does. any action will do.
i have to assume that you have apps on your device which can be launched
by receiving an intent. this means that when the android studio app broadcasts
a message, android should show a list of apps which can receive an intent.
is this what happens? if not, then there is more to the library than simply
communicating via intents. i notice there seems to be some sort of "key" needed.
if the system shows a list of apps (as described) above, then you can create a
small b4a app to get on that list and receive the message. there is no sense
in getting into that if the message from the android studio app does not cause
android to show a list of apps that can handle the intent.
frankly, i don't understand why you even need liveeventbus. if you know what
android studio app is observing (listening for), you can do it yourself. there is
an observable library here.
