Capacitor 3 & Facebook Android SDK，如何在ActivityCallback方法中获取请求代码

问题描述

目前我正在使用 Capacitor 3 和 Facebook Android SDK 创建我自己的 Facebook 登录插件。我被困在 onActivityResult facebook 方法上，我需要传递活动请求代码。如何获取此代码？

@CapacitorPlugin(
        name = "FacebookLoginSdk",permissions = {
                @Permission(
                        alias = "internet",strings = {Manifest.permission.INTERNET}
                )
        }
)
public class FacebookLoginSdkPlugin extends Plugin {

    ...
    @PluginMethod
    public void login(PluginCall call) {
        callbackId = call.getCallbackId();
        bridge.saveCall(call);

        if (getPermissionState("internet") != PermissionState.GRANTED) {
            requestPermissionForAlias("internet",call,"internetPermsCallback");
        } else {
            logInWithReadPermissions(call);
        }
    }

    @PermissionCallback
    private void internetPermsCallback(PluginCall call) {
        if (getPermissionState("internet") == PermissionState.GRANTED) {
            logInWithReadPermissions(call);
        } else {
            call.reject("Permission is required");
        }
    }

    private void logInWithReadPermissions(PluginCall call) {
        Activity activity = getActivity();
        Intent intent = activity.getIntent();

        startActivityForResult(call,intent,"loginResultCallback");
        loginManager.logInWithReadPermissions(activity,Arrays.asList(facebookPermissions));
    }

    @ActivityCallback
    private void loginResultCallback(PluginCall call,ActivityResult result) {
        if (call == null) {
            return;
        }
        int resultCode = result.getResultCode();
        Intent data = result.getData();

        callbackManager.onActivityResult(???REQUEST_CODE???,resultCode,data);
    }
}

解决方法

我正在寻找的属性是 FACEBOOK_SDK_REQUEST_CODE_OFFSET
