You can try this way as well. I have tried and tested it myself.

Step 1 : Please Download thejava-json.jar

Step 2: Add this to/libsfolder of your project then add to build path.

Step 3: Then use it as follows

• Imports to look for

  import org.json.JSONException; import org.json.JSONObject; import org.json.XML;

• Sample string

  String sampleXml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + "<mobilegate>" +"<timestamp>232423423423</timestamp>" + "<txn>" + "Transaction" + "</txn>" + "<amt>" + 0 + "</amt>" + "</mobilegate>"; 

• Json String

  JSONObject jsonObj = null; try { jsonObj = XML.toJSONObject(sampleXml); } catch (JSONException e) { Log.e("JSON exception",e.getMessage()); e.printStackTrace(); } Log.d("XML",sampleXml); Log.d("JSON",jsonObj.toString());

Output:

XML:

<?xml version="1.0" encoding="utf-8"?><mobilegate><timestamp>232423423423</timestamp><txn>Transaction</txn><amt>0</amt></mobilegate>

JSON :

{"mobilegate":{"timestamp":232423423423,"amt":0,"txn":"Transaction"}}
