Cannot create a map using native.newMapView

I created a Maps API key and my Buildsettings looks like:

settings =
{
	orientation =
	{
		default ="portrait",
		supported = {"portrait"},
	},
    android =
    {
        usesPermissions =
        {
            "android.permission.INTERNET",
 
            --optional permission used to display current location via the GPS
            "android.permission.ACCESS_FINE_LOCATION",
 
            --optional permission used to display current location via WiFi or cellular service
            "android.permission.ACCESS_COARSE_LOCATION",
        },
        usesFeatures =
        {
            -- If you set permissions "ACCESS_FINE_LOCATION" and "ACCESS_COARSE_LOCATION" above,
            -- you may want to set up your app to not require location services as follows.
            -- Otherwise, devices that do not have location sevices (such as a GPS) will be unable
            -- to purchase this app in the app store.
            { name = "android.hardware.location", required = false },
            { name = "android.hardware.location.gps", required = false },
            { name = "android.hardware.location.network", required = false }
        },
    },
    iphone =
    {
        plist =
        {
            NSLocationAlwaysUsageDescription = "This app would like to use location services.",
            NSLocationWhenInUseUsageDescription = "This app would like to use location services.",
        },
    },
}

My config.lua looks like:

application =
{
	content =
	{
	},
    license =
    {
        google =
        {
            mapsKey = "XXXXXXXXXXXXXXXXXXXXX",
        },
    },
}

Finally I create the mapview in a scene whose code looks like this:


--- These 2 lines should appear in every composer scene
local composer = require( "composer" )
local scene = composer.newScene()

-- -----------------------------------------------------------------------------------
-- Code outside of the scene event functions below will only be executed ONCE unless
-- the scene is removed entirely (not recycled) via "composer.removeScene()"
-- -----------------------------------------------------------------------------------


-- -----------------------------------------------------------------------------------
-- Scene event functions
-- -----------------------------------------------------------------------------------

scene.create = function(self,event)
	-- Create a native map view
 end
 
scene.show = function(self,event)
	local sceneGroup = self.view
	local phase = event.phase

	if ( phase == "will" ) then
		-- Code here runs when the scene is still off screen (but is about to come on screen)
		local myMap = native.newMapView(display.contentCenterX,display.contentCenterY, display.contentWidth-300, display.contentHeight-300  )

		 
		-- Display map as vector drawings of streets (other options are "satellite" and "hybrid")
		myMap.mapType = "standard"
		-- Initialize map to a real location
		myMap:setCenter( 37.331692, -122.030456 )
	elseif ( phase == "did" ) then
		-- Code here runs when the scene is entirely on screen
	end

end
scene.hide = function(self,event)
	local sceneGroup = self.view
	local phase = event.phase

	if ( phase == "will" ) then
		-- Code here runs when the scene is on screen (but is about to go off screen)
		print("will hide")
		
	elseif ( phase == "did" ) then
		-- Code here runs immediately after the scene goes entirely off screen
		print("did hide")
	end
end
scene.destroy = function (self, event )

	local sceneGroup = self.view
	-- Code here runs prior to the removal of scene's view
end

-- -----------------------------------------------------------------------------------
-- Scene event function listeners
-- -----------------------------------------------------------------------------------
scene:addEventListener( "create", scene )
scene:addEventListener( "show", scene )
scene:addEventListener( "hide", scene )
scene:addEventListener( "destroy", scene )
-- -----------------------------------------------------------------------------------

return scene

On running the build on the phone I see this:

Can’t figure out what is wrong. Any help would be appreciated.
