Hello. First of all ask forgiveness for my English

I watched the tutorial several times and no errors but the screen always blank
I downloaded the "www.b4x.com/android/files/googlemap.apk" file and it works perfect on my end but my code B4A always blank screen

Something I do wrong.

Please needed for my application

I enclose three images. Thank you very much for everything

Hi.
If your api key is correct and google map service is started,use proxy in your device and i will see google map shown.
My problem is white screen but when use proxy ,google map show in mapview

The API in the APK file is correct (it was tested by many users). I think that there is a problem with your device configurations.
I fix it Erel.I install proxy app and open google map and it's work :)

Our app works perfectly on the smartphones we've tested it on. But the tablet of my brother shows a white map...Any ideas?

Hi Erel, our app works fine on some devices when debugging (only low resolution). But on other device it shows the wite map.
Google play services are properly installed on those devices but the test app does work correct.

have loaded my existing keystore , went to google developer console ,

1.create new project at the google developer console
2. enabled : Google Maps Andriod API ( no version 2 found , only this option found )
3. created : Credential, API Key,
3.1. Name : Andriod key1 , package name : com.example.android.mapexample and filled in my SHA-1 fingerprint found at the dialog of my keystore
when open up the private signed key at B4A ,
4. added code to manifest file as suggested , and replaced the key value with my own API key ,
5. added an #AdditionalRes attribute to the main activity
6. after compiled & installed , the MAP display is BLANK , with "google" word at the left bottom corner ,

* i have installed your B4A demo.apk found in this thread and the map display correctly and is working properly.
