GoogleMap V2 Failed to load map.Error contacting Google servers

Question

I am using a Google Api 19.I am getting the Stacktrace error at runtime while running the Google map V2. Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

StackTrace:

I doesn't know how to solve these stackTrace Error.Anybody can help me with these.Thank You.

Answer 1

For me the issue was in that I have used network_security_config setting in Manifest under the application tag.

I am still not sure how to handle it correctly but after I just removed that setting (occasionally it wasn`t needed for my project) Maps become to work.

Answer 2

I solved these problem by doing the following steps:

• In Emulator:

  You have to use the latest API Google APIs(Google Inc.)-API Level 19.

  Do the rest of the things placed in the screenshot itself.

  

• API Key:

  Create New API Key and Check carefully about Google Map API key and SHA Key.

• Google Play Services:

  You have to download the latest Google Play Services com.android.vending-4.8.20.apk.In that site if google play services wasn't working means you can find a lot of sites in internet named com.android.vending 4.8.20.apk.

  you can run the Google play Services by using the Command Prompt adb install com.android.vending 4.8.20.apk.

  Note: You have to download the latest Google play services because year by year latest version will be updated in internet.
