To ensure that your Unreal Android application will properly work with the Vivox SDK, you need to request the

android.permission.RECORD_AUDIO

and, on Android 12 and later, the

android.permission.BLUETOOTH_CONNECT

permissions at runtime. To do this, use

UAndroidPermissionFunctionLibrary::CheckPermission

to check if these permissions are granted, and

UAndroidPermissionFunctionLibrary::AcquirePermissions

to request the permission for the user.

The following code is an example of this process:


#if PLATFORM_ANDROIDconst FString BluetoothConnectPermission = TEXT("android.permission.BLUETOOTH_CONNECT");if (!UAndroidPermissionFunctionLibrary::CheckPermission(BluetoothConnectPermission)) {    permissions.Add(BluetoothConnectPermission);    UAndroidPermissionFunctionLibrary::AcquirePermissions(permissions);}#endif

You also need to add the

AndroidPermission

module into the dependency in the

[PROJECT].build.cs

file. For example:


PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "AndroidPermission" });

For more information on how to request permissions by using the Blueprint API, refer to the the Unreal documentation on Android Permission.
