如何使用云打印来打印Android的活动展示 [英] How to print Android activity display using cloud print

问题描述

我想实现谷歌云打印成一个应用程序，继集成指南。我试图保持它的基本只需打印出google.com。当我点击创建打印按钮，将弹出的对话框中，但我正在逐渐出现FileNotFoundException说明

I am trying to implement Google Cloud Print into an app, following the Integration Guide. I'm trying to keep it basic by just printing out google.com. When clicking the print button I created, it brings up the dialog, but I am getting a FileNotFoundException stating

java.io.FileNotFoundException：没有内容提供商：
   http://www.google.com

java.io.FileNotFoundException: No content provider: http://www.google.com

如果我再选择一台打印机，并单击打印对话框给了我一个文档中缺少信息的基础上，FileNotFoundException异常这是有道理的。

If I then select a printer and click print, the dialog gives me a "Document Missing" message, which makes sense based on the FileNotFoundException.

我把print_dialog.xml和PrintDialogActivity.java逐字从导向。这里是我的code调用活动：

I took print_dialog.xml and PrintDialogActivity.java verbatim from the guide. Here is my code calling the activity:

Intent printIntent = new Intent(getActivity(), PrintDialogActivity.class);
Uri docUri = Uri.parse("http://www.google.com");
printIntent.setDataAndType(docUri, "text/html");
printIntent.putExtra("title", "Google");
startActivity(printIntent);

我试图找出如何打印网页，但最终希望能够打印活动显示。

I'm attempting to figure out how to print a web page, but would eventually like to be able to print the activity display.

所以我的问题是：我需要什么才能打印网页或活动显示做

So my question is: What do I need to do in order to print a webpage or activity display?
