Android hashmap converting to JSON in the wrong format

I've got a random issue that I cannot seem to work out. Given the following code:

HashMap<String, Object> params = new HashMap<String, Object>();
params.put("method","getProducts");

HashMap<String, String> methodParams = new HashMap<String, String>();
methodParams.put("currency", currency);

params.put("params", methodParams);
restClient.setBodyValueForKey("json", new JSONObject(params).toString());

The following hashmaps are converted to JSON and sent to a PHP server.

The server should receive the data in the following format via POST

Array
(
   [json] => {"method":"getProducts","params":{"currency":"GBP"}}
)

On some android devices (not sure what the determining factor is) this is correct but on others it is being sent as

Array
(
   [json] => {"method":"getProducts","params":"{currency=GBP}"}
)

As you can see the second hash map is being converted into a string and not being added as a HashMap

Does anyone know what could be causing the inconsistency in parsing the HashMaps?

Thanks

The problem is with the wrap function which is inside JSONObject class. As it works >= API 19. That's why it not able to convert properly. You can use GSON for that.

Try doing the following

HashMap<String, Object> params = new HashMap<String, Object>();
params.put("method","getProducts");

HashMap<String, String> methodParams = new HashMap<String, String>();
methodParams.put("currency", currency);

params.put("params", new JSONObject(methodParams));
restClient.setBodyValueForKey("json", new JSONObject(params).toString());

UPDATE

// replace
params.put("params", new JSONObject(methodParams).toString());
//with
params.put("params", new JSONObject(methodParams));
