Android Google MapView shows only empty fragments

Question

I tie to the creation of a simple application that displays a map.

I got the debug.keystore API key and the triple checked it for correctness.
I also exported the project as apk and used a custom keystore with the corresponding API key.

I have the following permissions:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.INTERNET" /> 

But on my devices and in the emulator so far only empty tiles are displayed.

EDIT:

These exceptions are repeated quickly.

There are no proxy or internet issues. The map application works.

maybe someone can help.

Answer 1

The only reason for empty slabs is a problem with key or proxy or Internet issues.

Check if the normal card application is working properly in your simulator. If so, then the problem is with your key. or the problem is with the proxy server or the Internet.

Remember to create a simulator using the Google APIs

• Have you checked LogCat? Perhaps you can find errors with error codes there, which you can find in the documentation. For example, you might have something like; onConnectionFailed: ConnectionResult.getErrorCode () = 4, and here you can follow here ConnectionResult Reference - Google

• Make sure your API key is correct. Google API v2 Registration
