//========================================================================
public static String retrieveJSONArray(ArrayList<String[]> jsonArray){

try{

String[] jsonObject=new String[2];
JSONStringer stringer=new JSONStringer();

stringer.array();

int arrayLength=jsonArray.size();

for(int i=0;i<arrayLength;i++){

jsonObject=jsonArray.get(i);

stringer.object();

for(int j=0;j<jsonObject.length;j++)
stringer.key("key"+j).value(jsonObject[j]);
