The app-URI authentication policy is set by the credential management app. This policy determines which alias for a private key and certificate pair should be used for authentication.

The authentication policy should be added as a parameter when calling[KeyChain.createManageCredentialsIntent](https://developer.android.com/reference/kotlin/android/security/KeyChain#createManageCredentialsIntent(android.security.AppUriAuthenticationPolicy)).

Example:  

```kotlin
<code>AppUriAuthenticationPolicy authenticationPolicy = new AppUriAuthenticationPolicy.Builder()
               .addAppAndUriMapping("com.test.pkg", testUri, "testAlias")
               .addAppAndUriMapping("com.test2.pkg", testUri1, "testAlias2")
               .addAppAndUriMapping("com.test2.pkg", testUri2, "testAlias2")
               .build();
      Intent requestIntent = KeyChain.createManageCredentialsIntent(authenticationPolicy);
  </code>
```
