All of a sudden maps stopped working in my app and just shows a blank screen with the google logo in the bottom left corner.
The error I get is:
I/G
I had exactly the same problem and the solution was not obvious at all. Check if you are not changing DefaultSSLSocketFactory with:
HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());
Removing this line and setting socket factory just for the required connection made my maps work.
