PathPrefix Path not working Android app Link

Dipannita Das 21

Following this tutorial https://learn.microsoft.com/en-us/xamarin/android/platform/app-linking

Created assetlinks.json https://dipannitadas.azurewebsites.net/.well-known/assetlinks.json

Added below code to MainActivity

[IntentFilter(new[] { Intent.ActionView },  
                  DataScheme = "https",  
                  DataHost = "test.yourdomain.com",  
                  DataPath = "/Ambassador/TCAnnualRenewal",  
                  AutoVerify = true,  
                  Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable })]  
      
    public partial class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity{

}

Install the app on debug mode on device via Visual Studio 2019.

If I remove DataPath = "/Ambassador/TCAnnualRenewal", https://dipannitadas.azurewebsites.net opens the app correctly
If add DataPath or DataPrefix none of the below links works including https://dipannitadas.azurewebsites.net

I have used keytool.exe -list -v -keystore "%LocalAppData%\Xamarin\Mono for Android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

and used SHA256 in the assetlinks.json

If you use PathPrefix, these will only work when using a SIGNED version of the app on your device. Because you have sha256_cert_fingerprints value in your assetlinks.json file, sha256_cert_fingerprints can only be verified when a signed app is used.

Thanks for response.

Tried loading signed apk using adb command which get stored inside debug folder
adb install package_name, PathPrefix did not work.
I am using same keystore to generate the sha256_cert_fingerprints which VS used to generate Signed apk.

keytool.exe -list -v -keystore "%LocalAppData%\Xamarin\Mono for Android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

@Leon Lu (Shanghai Wicresoft Co,.Ltd.) is there a way to configure DataHost dynamically for different environments? instead hardcode

No, I cannot find a way to set it DataHost dynamically.
