webView on Android crashes

I am using native.newMapView() to display a map. While it runs fine on iPhones and most Android phones, it displays the map for 2 seconds on some Android phones and then gives this error:

Translation: “Oops, an error occured! Google Maps wasn’t loaded on this site correctly. You can find technical details in the JavaScript console.”
It doesn’t say anything about it in the logs. Does anyone know where the problem is?
