Blue screen in Android Google Maps

Question

I am getting a blue screen when I load my Google Maps on Android. I don't know what I am doing wrong, this is my code for getting the locations:

MapView mapView = (MapView) findViewById(R.id.mapDire);
Route route = directions(new GeoPoint((int)(2*1E6),(int)(34*1E6)),
  new GeoPoint((int)(3*1E6),(int)(36*1E6)));

I think can be two things

Your coordinates are 0,0 and the map is opening in the ocean
Something wrong with your API Key

In the first case try zoom out a lot of times and try to see some continent.

In the second try to read the documentation or/and try this link

I hope this helps.

I have this problem in my application and see below code in onlocationchanged method and resolve it.

LatLng myCoordinates = new LatLng(location.getLatitude(), location.getLongitude());
         mMap.moveCamera(CameraUpdateFactory.newLatLng(myCoordinates));

    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 17.0f));

    marker.setPosition(myCoordinates);

Normally blue screen means your Google API key didn't work.

If your map is not showing, only grids/blank screen showing, that's because your Map API key is missing or incorrect. Sign up for Google Android Map API.

Try this the link for more info.

There could 3 reasons as to why You see blue screens

Your Long/Lat Points to Water region - or Ocean region, Invariably there's nothing wrong just you Long/Lat Pointing to Water which is blue in color.
Your Long/Lat is wrong and nothing comes up
Your API key is wrong which can be corrected on your Android manifest file directory: Android/app/src/main/AndroidManifest.xml

An additional possibility is that you need to add proguard rules to your proguard-rules.pro

# Google Maps
# Needed to avoid a blue screen map
-keep,allowoptimization class com.google.android.libraries.maps.** { *; }
-keep,allowoptimization class com.google.android.apps.gmm.renderer.** { *; }
