Json Parsing In Android: No Value For X Error

Here is the code I'm using inside my AsyncTask DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet request = new HttpGet(url); request.setHeader('Accept', 'appl

Solution 1:

No value for x error message is pretty common when dealing with JSON. This usually resulted by overlooked code.

usually, when dong JSON, I try to see the human readable structure first. For that, I usually use JSONViewer.

In your case, the structure is something like this:

You see that make is within another object called GetJSONObjectResult. Therefore, to get it, you must first get the container object first:

JSONObject vehicle = ((JSONObject)newJSONObject(result)).getJSONObject("GetJSONObjectResult");
//a more easy to readJSONObject container = newJSONObject(result);
JSONObject vehicle = container.getJSONObject("GetJSONObjectResult");

and finally use the object to get make:

makeEdit.setText(vehicle.getString("make"));
plateEdit.setText(vehicle.getString("plate"));
modelEdit.setText(vehicle.getString("model"));
yearEdit.setText(vehicle.getString("year"));

Solution 2:

Your JSON Object contains itself a JSONObject. To acces to your data, you have to do like this:

vehicle.getJSONObject("GetJSONObjectResult").getString("make");
