This describes a way to submit HTTP POST in a way the REST interface provided by Tastypie to Django understands it for JSON data

HTTP Post Android to Django Tastypie

//Creating the data to be sent, note the escaped quotes that are required

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);

nameValuePairs.add(new BasicNameValuePair("\A\"", "\"/api/v1/a/1/\""));

nameValuePairs.add(new BasicNameValuePair("\"B\"", "\"/api/v1/b/1/\""));

nameValuePairs.add(new BasicNameValuePair("\"C\"", "\"Hello from Android\""));



//Create the client and set headers

HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost(urlToPost);

httppost.setHeader("content-type", "application/json");


//Setting the Authorization header

String encoded = "Basic " + Base64.encodeToString((username+":"+password).getBytes("UTF-8"), Base64.URL_SAFE|Base64.NO_WRAP);

httppost.setHeader("Authorization",encoded);


//String the data and set it as HTTP Parameters in the POST request

StringEntity entity = new StringEntity(getQueryJSON(nameValuePairs));

httppost.setEntity(entity);

HttpResponse response = httpclient.execute(httppost);

if(response!=null){

InputStream in = response.getEntity().getContent(); //Get the data in the entity

readStream(in);

}


//Utility function to encode the JSON to string
private String getQueryJSON(List<NameValuePair> params) throws UnsupportedEncodingException

{

    StringBuilder result = new StringBuilder();
  
    boolean first = true;

    for (NameValuePair pair : params)

    {

    if (first){

        first = false;

        result.append("{");

    }else

        result.append(",");


    result.append(pair.getName());

    result.append(":");

    result.append(pair.getValue());


    }

    result.append("}");

    return result.toString();

}

This is awesome, thank you very much!
