I applied the exact steps as mentioned in the google developer doc to create an example google map project and everything went fine on the emulator, but when I generated the

Answer 1

Check the following things:

• This below file should be in both debug and release

  app\src\debug\res\values\google_maps_api.xml (debug)
  

  You also need to include in

  app\src\release\res\values\google_maps_api.xml (release)
  

• Add the SHA1 for release apk into Google Api Console.
  You can get SHA1 key from play console >> App Signing >> SHA1 Certificate

Answer 2

I also had the same issue of map when I'm making the apk , make apk in the same system in which system you have made the google map key then the map will work and show perfectly .

Answer 3

if any one still facing this problem :

this happend to me because we need two google maps api keys one for the debug and another one for the release, you can check in :

C:\Users\username\AndroidStudioProjects\yourapp\app\src\ debug \res\values and you'll find an xml with your api key like:

    <string name="google_maps_key" templateMergeStrategy="preserve" 
          translatable="false">AIza...etc</string>

but if you check here:

C:\Users\username\AndroidStudioProjects\yourapp\app\src\ release \res\values you will find an xml but without api key inside like:

     <string name="google_maps_key" templateMergeStrategy="preserve" 
         translatable="false">YOUR_KEY_HERE</string>

it was noted as a comment inside the xml file itself :

Before you release your application, you need a Google Maps API key.

To do this, you can either add your release key credentials to your existing
key, or create a new key.

Note that this file specifies the API key for the release build target.
If you have previously set up a key for the debug target with the debug signing certificate,
you will also need to set up a key for your release certificate.

Follow the directions here:

https://developers.google.com/maps/documentation/android/signup

Once you have your key (it starts with "AIza"), replace the "google_maps_key"
string in this file.

Answer 4

now google signed apk before publish on store,so go to google pushish app ---> app signning , and add signed key to google developer console,you shoud add 3 key sha1 : debug,release and new sha1 key after pushlish

Answer 5

For showing the map in release version of android apk, developer needs to add the updated SHA-1 key, created by Google Play console after publishing the application. Go to App Signing section of the console and look for 'App Signing Certificate: SHA-1 Certificate Fingerprint'. Copy the fingerprint and paste it in Google API Console where developer has created the Google API key for map.

Answer 6

Reason for this issue

This occurred because there are different SHA1s in debug and release types.

Fix for this issue

Add the SHA1 of the keystore used to build the release APK to Google console

Steps:

1. Get the path of the keystore when you generate signed APK

   Build ----> Generate Signed APK..

Save the key store path

Remember to make Build Type --- release

2. Extract SHA1 from the keystore.

Open your terminal use command below:

 keytool -list -v -keystore "/Users/NT/Desktop/generalkey.jks"

You will be asked for password for your keystore.

Change path to your keystore path keytool -list -v -keystore "keystore path"

From the Certificate fingerprints, you will see the SHA1

3. Generate android key using this SHA1 and your package name

Generate APK using keystore and enjoy your map
