in-app - Facebook Android 自动应用内购买记录数据错误

Question

我使用 facebook Android SDK（版本 4.28）进行自动应用内购买记录，我按照DOC添加代码

我的代码是：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // Pass on the activity result to the helper for handling
    if (!mInAppBillingManager.onActivityResult(requestCode, resultCode, data)) {
        // not handled, so handle it ourselves (here's where you'd
        // perform any handling of activity results not related to in-app
        // billing...
        super.onActivityResult(requestCode, resultCode, data);
    }
    if (requestCode == 10001) {
        CallbackManager callbackManager = CallbackManager.Factory.create();
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }
}

但应用内购买数据是错误的。请帮帮我
