Hi,

Is there a code snippet which can be used to download a File from Microsoft Health Vault in the Android platform? Also the code available on How to do for uploading file, does it support Android?

Sana.

Hi Sana,

There isn't an example using the Java sdk.  Using the Android library you will be creating and parsing the XML requests directly.  Here is a blog post describing the XML format necessary for blob support:  http://blogs.msdn.com/b/ericgu/archive/2011/05/24/dealing-with-blob-data-in-healthvault-xml.aspx

So with the blog, I followed it step by step and added the new extra section.

String infoFile = "<info><group max=\"100\"><filter><type-id>" +
        File.TYPE +
        "</type-id></filter><format><section>core</section><section>blobpayload</section> " +
        "<xml/></format></group></info>";

But it gives me a xml parse error saying that section element is invalid and bobpayload is invalid according to its datatypes.....

Also in the documentation under "http://developer.healthvault.com/sdk/docs/urn.com.microsoft.wc.methods.GetThings.ThingSectionSpec.1.html" I don't see any bobpayload enum at all. Am I missing something here?

Just to add to the bloggers curiosity, when I add the filter "<section>otherdata</section>" it gives me the response in

<data-other content-type="text/plain" content-encoding="base64">***Content here is in Base64 format***</data-other>

which I encode it back to my format.

So I would like to know which is a cleaner method of doinf stuff? the blog or should I go ahead with "otherdata"?

The blobpayload section was added in GetThings version 3.  It's best to use the latest versions of the methods:  GetThings v3, PutThings v2.

So I guess for uploading I will be using PutThings version 2.

I guess it should have been updated in the blog with version 3. Anyways thanks a lot for fetching data it worked perfect!

Thanks a lot, the documentation of HealthVault has to be updated! Can anyone voluntarily update them?

In case anyone is reading these older discussions, here are the steps required to get this working on android; just add a few lines to the code for the "Weighter" sample app as indicated below:

@SuppressWarnings("unchecked")
public static String getRawXml_n_BinaryData(Record record, String HV_TYPE) {
    SimpleRequestTemplate template = new SimpleRequestTemplate(
	HealthVaultService.getInstance().getConnection(),
        record.getPersonId(),
        record.getId());

    String info = "<info>" +
    "<group max=\"25\">" +
        "<filter>" + 
            "<type-id>" + HV_TYPE + "</type-id>" + 
        "</filter><format>" + 
            "<section>core</section>" +
            "<section>blobpayload</section>" +
            "<xml/>" + 
            "<type-version-format>" + HV_TYPE + "</type-version-format>" +
            "<blob-payload-request>" +
                "<blob-format>" +
                    "<blob-format-spec>inline</blob-format-spec>" +
                "</blob-format>" +
            "</blob-payload-request>" +						
        "</format>" + 
    "</group>" +
"</info>";

    Request request = new Request();
    request.setMethodName("GetThings");
    request.setMethodVersion("3");

(Note that you don't need to mess around with fancy imports or changing the method name; just use "3" for the method version)

HTH

Thanks for adding to the knowledge here!
