Actions with a Blank Card After Uploading to the Play Store

Question

As mentioned in the title, Maps activity is shown blank (with the Google logo at the bottom) after I downloaded the app. I know this question has been asked many times, but none of the solutions can solve my problem.

This is what I have done so far:

• The generated Google Maps Release API key (signed SHA-1) after the official guide here and placed it under the release / res / values ​​/ google_maps_api.xml
• Put the hardcode release API key in AndroidManifest.xml
• Clean and rebuild project

This is the result:

• Maps activity just worked fine if the release.apk application was manually installed on the device before downloading to the Play Store.
• Maps activity is displayed empty if app-release.apk after downloading the release-app.apk application to the Play Store.

Decision:

This answer solved the problem that I am facing. The reason the Maps activity is shown to be empty is because Google Play is re-signing the application using the original application signing key that I provided. So just copy Google SHA-1 and paste it into the console where the Google Map API key is generated.

If GMap activity is added in any project, then there are two google_maps_api.xml files.
One for Debug and One for release.

You probably entered the key in Debug just as when we add Gmap activity, only google_maps_api.xml is opened. Therefore, put your key in Release. How? ... see

• Click the TODO button on the bottom panel of Android Studio.
  
• Click the TODO Based Area tab.
• Now there are two google_maps_api.XML files, each open and copy your XML key without the key (YOUR_KEY_HERE). It also happened to me.

You missed adding permission, try checking by enabling permission.
