this line is not needed since we do not have a custom install command for this plugin

Might be a good idea to return an observable here.

@Cordova({
  observable: true
})
static addEventListener(eventName: string): Observable<any> { return; }

[mebibou]

What would be the difference?

[ihadeed]

A promise resolves once, an observable can fire as many times as you want until you unsubscribe from it.

It should also have the following decorator instead of just observable: true, this will make sure we unsubscribe from the event when unsubscribing from the observable:

@Cordova({
  observable: true,
  clearFunction: 'removeEventListener',
  clearWithArgs: true
})

[mebibou]

ah yes correct, will do

[mebibou]

by the way, I should probably add the removeEventListener definition, but to work it needs the function passed in the observable or the addEventListener function, which seems a bit strange, doesn't it?

[ihadeed]

No you don't need to add the removeEventListener. The @Cordova decorator will do the magic needed once you add the options I mentioned in my last comment.

[ihadeed]

Adding the clearFunction option will call that function when you unsubscribe from the observable. The clearWithArgs option will pass the same arguments passed to addEventListener (which are needed in this case).
