Question

我正在尝试将askForPermisions函数实现为AIR的Adobe Native Extension（ANE）。我的功能现在定义为：

public class APKaskForPermission implements FREFunction  {
    public static final String TAG = "askForPermission";
    @Override
    public FREObject call(FREContext ctx, FREObject[] passedArgs) {
        FREObject result = null;
        String permission;
        Integer requestCode;

        try{
            permission = passedArgs[0].getAsString();
            requestCode = passedArgs[1].getAsInt();

            if (ContextCompat.checkSelfPermission(NativeExtension.appContext, permission) != PackageManager.PERMISSION_GRANTED) {

                // Should we show an explanation?
                if (ActivityCompat.shouldShowRequestPermissionRationale(ctx.getActivity(), permission)) {
                    Log.d(TAG, "shouldShowRequestPermissionRationale: " + permission);
                    //This is called if user has denied the permission before
                    //In this case I am just asking the permission again
                    Log.d(TAG, "requestPermissions: " + permission);
                    ActivityCompat.requestPermissions(ctx.getActivity(), new String[]{permission}, requestCode);

                } else {
                    Log.d(TAG, "requestPermissions: " + permission);
                    ActivityCompat.requestPermissions(ctx.getActivity(), new String[]{permission}, requestCode);
                }
                result = FREObject.newObject(false);
            } else {
                Log.d(TAG, "" + permission + " is already granted.");
                //Toast.makeText(this, "" + permission + " is already granted.", Toast.LENGTH_SHORT).show();
                result = FREObject.newObject(true);
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }

        return result;
    }
}

这会按预期显示对话框，但我无法找到如何获取响应，因为Web上的所有示例都在MainActivity源中定义它，但我在本机扩展上下文中。

有任何帮助吗？

正如<{3}}中提到的 Wadedwalker ，无法在运行时覆盖或添加方法到另一个类，在本例中为主AIR应用程序活动。因此，最好的方法是启动一个新的空白活动，以便触发弹出窗口，以便能够等待onRequestPermissionsResult（）响应。

我设法获得了自己的基本ANE版本，这是在这里开源的：this discussion

如何从Adobe Native Extension（ANE）上下文中运行的ActivityCompat.requestPermissions接收响应？
