Google雲打印無需webview集成

Question

我使用this教程將我的android應用程序與Google雲打印機集成在一起。它工作正常，但我想這樣做沒有WebViw。

我想有兩個步驟打印：

1. 生成PDF文件
2. 點擊按鈕 「打印」，並提交打印作業

我分享我的打印機給任何人鏈接，並希望從我的應用程序打印到我的共享打印機的所有PDF文件。

你可以分享一些代碼或教程嗎？

對不起，我的英語

我發現this鏈接，它可以幫助我

地址：

@Override 
protected Void doInBackground(Void... params) { 

    try { 
     DefaultHttpClient httpclient = new DefaultHttpClient(); 

     String user = "user@gmail.com"; 
     String pass = "password"; 
     String source = "Cloud%20Printing%20Test"; 

     HttpGet authGet = new HttpGet(
       "https://www.google.com/accounts/ClientLogin?accountType=HOSTED_OR_GOOGLE&Email=" 
         + user 
         + "&Passwd=" 
         + pass 
         + "&service=cloudprint&source=" + source); 

     HttpResponse httpResponse; 

     httpResponse = httpclient.execute(authGet); 

     String authResponse = EntityUtils 
       .toString(httpResponse.getEntity()); 
     String authKey = authResponse.substring(authResponse 
       .indexOf("Auth=") + 5); 
     authKey = authKey.replace("\n", ""); 

     MyLog.d(TAG, "Auth key: " + authKey); 

     HttpPost printPost = new HttpPost(
       "https://www.google.com/cloudprint/submit?output=json"); 
     printPost.setHeader("Authorization", "GoogleLogin auth=" + authKey); 
     printPost.setHeader("X-CloudPrint-Proxy", source); 

     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 
     nameValuePairs.add(new BasicNameValuePair("printerid", "ID")); 
     nameValuePairs.add(new BasicNameValuePair("title", "TEST")); 
     nameValuePairs.add(new BasicNameValuePair("capabilities", "{capabilities=[]}")); 
     nameValuePairs.add(new BasicNameValuePair("content", "123")); 
     nameValuePairs.add(new BasicNameValuePair("contentType", "text/plain")); 
     printPost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

     HttpResponse printResponse = httpclient.execute(printPost); 
     String lol = EntityUtils.toString(printResponse.getEntity()); 

    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    return null; 
} 

但現在我只能打印文本。如果我找到解決方案如何打印PDF - 我會張貼在這裏的代碼

ADD2：

該代碼發送PDF文件打印

File file = new File("file.pdf"); 
FileBody fb = new FileBody(file); 
MultipartEntityBuilder builder = MultipartEntityBuilder.create(); 
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); 
builder.addTextBody("printerid", "ID"); 
builder.addTextBody("title", "TEST2"); 
builder.addTextBody("capabilities", "{capabilities=[]}"); 
builder.addTextBody("contentType", "application/pdf"); 
builder.addPart("content", fb); 
printPost.setEntity(builder.build());
