Make sure you enter your release API key in the google_maps_api.xml under the release folder. 

First, switch to Project view by using the dropdown in the upper left of the Project Explorer. Then, expand <code>app/src/</code>, and you will see subfolders <code>debug</code> and <code>release</code>. Under there, you should see two separate google_maps_api.xml files under <code>debug/res/values</code> and <code>release/res/values</code>.

Make sure that the release API key is in the google_maps_api.xml file under the <code>release/res/values</code> folder, since this is the one that will be used for the signed release apk.

<li>Create a new google map activity.</li>
<li>Go to google_maps_api.xml.</li>
<li>Copy the link given in that file in paste in browser(login to google account).</li>
<li>On google create some project here and press continue</li>

<li>Copy the key and paste in google_maps_api.xml

And execute the application

Do not use below fingerprint, or key, create your separate it is based on package ans application

Ask them to choose <code>Upload a key exported from Android Studio</code>. They will have to upload a <code>private_key.pepk</code> file. This is how you get that file from Android Studio:

<ul>
<li>Go to <code>Build &gt; Generate Signed Bundle / APK...</code>.</li>
</ul>

<a href="https://i.stack.imgur.com/ACbYI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ACbYI.png" alt="enter image description here"></a>

Select <code>Android App Bundle</code> and click <code>Next</code>:

<a href="https://i.stack.imgur.com/yin0K.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yin0K.png" alt="enter image description here"></a>

Provide the corresponding credentials and make sure to put the check on for <code>Export encrypted key for enrolling published apps in Google Play App Signing</code>.

<a href="https://i.stack.imgur.com/6ZOoI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6ZOoI.png" alt="enter image description here"></a>

Specify the destination folder and make sure you select <code>release</code> before you click <code>Finish</code>:

<a href="https://i.stack.imgur.com/QkGkD.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QkGkD.png" alt="enter image description here"></a> 

That will generate the <code>private_key.pepk</code> file that you need to provide to <code>Upload a key exported from Android Studio</code>.

After doing the above, when you to to the <code>App signing</code> section of your app, you will see something like this:

<a href="https://i.stack.imgur.com/zUKba.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zUKba.png" alt="enter image description here"></a>

Then you will see the Google Maps working correctly on real Android Studio physical devices and not only on the Android Studio Emulator. This was the solution for me.

googled it, read millions of advices about how to generate google API key, how to use it but nothing works!

<ol>
<li>enabled google maps v2 API</li>
<li>created project with one activity with google map (default wizard in studio)</li>
<li>created key on google for debug project, assigned SHA1;app package of application to the project key on google</li>
<li>API key inserted into google_maps_api.xml (AndroidManifest.xml updated automaticaly)</li>
<li>build &amp; run on AVD on which the app is working, map is shown.</li>
</ol>

Then:

<ol>
<li>API already enabled</li>
<li>in Android studio created keystore for release (keystore.rel.jks)</li>
<li>generated fingerprints (keytool -list -v -keystore C:\Dropbox\AndroidKeyStore\keystore.rel.jks)</li>
<li>on google added new fingerprint to the new release project (release SHA1;app package) - key generated AIza...</li>
<li>API key inserted into google_maps_api.xml (AndroidManifest.xml updated automatically)</li>
<li>generate signed app (using keystore.rel.jks) &amp; install on real device ... app is working, map is STILL BLANK, only zoom buttons and Google label is on</li>
</ol>

Thanks in advance for any advice.
