Google Maps API Issue

I have a google maps implementation that has various dropped pins. When clicked they open a information window. Now this works just fine in Ionic Serve but when trying on the emulator or device is does not work.
I set the data-tap-disable="true" on my map div. What could be the problem? Also is it possible to transfer the dropped pins from the google maps to the native maps app on the device? Really need assistance on this one, thanks in advanced.
