Ohh I see.... you're implementation is base on Observables... Let's wait until Ionic Team gives there feedback... :(

[mostafa-mansour1]

oops, this pull request has been approved and the original one conflict with it, what we should do to resolve it, I already wrote the documentation based on observables

[mostafa-mansour1]

can i revert the changes to add my code and documentation?

[jbagaresgaray]

@mostafa-mansour1 I think Ionic accepts base on Promise response as most of the plugins returns promise as well.. consult @danielsogl instead...

[mostafa-mansour1]

ok no problem, but we need at least to fix the docs,
