Android Question "White Map" with Google Maps v2

[Walter Adriano da Silva]

Hello there,

I'm using Google Maps v2 for an app, and have right configs in Google API Key, AdditionalRes and Manifest, but the panel persist in show me a "White Map".



One can imagine where is the error?

Thank you in advance.

Make sure that Google Maps API is enabled in your developer console.

Check the unfiltered logs. There will probably be a message about authorization failure.

You can download a compiled working example: www.b4x.com/android/files/googlemap.apk

Thanks Erel,

I was with the Google Maps API enabled on another project. Silly mistake.

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

The problem is in the second image. The API key should be followed with the package name not the keystore file name.

Is this an unrooted device running standard Android with Google services?

Check the unfiltered logs (in usb debug mode). There might be more information.

 

[omidaghakhani1368]

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
Thank you Erel

 

[Erel]

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.

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

 

[Erel]

Make sure that Google Play Services is installed.

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.

 

[Erel]

Check the APK I posted in post #2 and see whether it works on these devices or not.
