Troubleshoting implementing on ionic cordova's project

I’m trying to configure cordova-plugin-googlemaps on my Ionic/Cordova’s project, so I followed the instructions contained in Installation on Windows But when I run my app none map is showed and I just receive those lines on console:

27010-27010/com.awesome.app I/dalvikvm: Could not find method android.content.pm.PackageManager.isInstantApp, referenced from method com.google.maps.api.android.lib6.drd.av.a 27010-27560/com.awesome.app I/dalvikvm: Could not find method android.os.PowerManager.isInteractive, referenced from method com.google.maps.api.android.lib6.drd.aa.a

Okay, I tested with the latest cordova version, but it has lots of problems. So please install like this.

$> git clone -b multiple_maps --single-branch  https://github.com/mapsplugin/cordova-plugin-googlemaps

$> cd (your project)

$> cordova platform rm android

$> cordova platform add android@6

$> cordova plugin (path to cordova-plugin-googlemaps) --variable API_KEY_FOR_ANDROID=".."
