Is there a way to set a Global JS Variable from inside a cordova plugin?
My situation is this; I have a library that is initiated from an Anonymous class. Once initiated it has a function that can be called via a pointer.
The function has no return; and merely sets a variable;
reader = new Reader(getApplicationContext(), new CardFlightDeviceHandler() {
...
/* Response */
@Override
public void readerCardResponse(Card card) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
"Device swipe completed", Toast.LENGTH_SHORT)
.show();
mCard = card;
fillFieldsWithData(card);
}
...
/* Call */
reader.beginSwipe();

Yes, this is possible.
You can store a value via SharedPreferences and access this value in JS.
You could use the NativeStorage plugin to retrieve a stored value.
See this thread, here a JS value is stored via NativeStorage and accessed in Android. Your application should be the other way around. Store a value with SharedPreferences with the correct PREFS_NAME ("NativeStorage"). And get the value via NativeStorage.
NativeStorage.getItem(<key>, function(value){}, function(error){});
