- Expected results
The map is correctly rendered in a device connected via usb, although the exception is thrown.
If an apk is generated and installed on the device, the map is not rendered, and the exception is thrown.
- Do you try using other devices?
Yes. I verified this process in a SMA426B and and a MiT11

In order to give a more detailed information to the problem, I enclose the previous and forward information given in terminal, in addition to the error itself:
I suppose it is not a problem of Google Play Services, since it is correctly read...
You also need to add INTERNET permission, add this line to androidManifes.xml
In you project level gradle change version of google play services to 4.3.15 in Plugins section.
