   Map<String, String> map =dataSnapshot.getValue(Map.class);

                String MR_ID = map.get("MR_ID");
                String JOB_TITLE = map.get("JOB_TITLE");
                String JOB_TYPE = map.get("JOB_TYPE");
                String Delv_ADDR=map.get("Delv_ADDR");

DataSnapshot { key = platformdb, value = {MR_RELATIONS={CUSTOMERS={ORDERS={INVENTORY=, Delv_ADDR=D-103 LaxmiNagar New Delhi, ORDER_ID=}}}, MR_SCHEDULE={MR_ID=, JOB_TITLE=, GEO_LINK=, JOB_TYPE={TSP={TSP_ADDR=, TSP_ID=, GEO_LINK=, TSP_NAME=}, SCC={SCC_ID=, SCC_ADDR=, GEO_LINK=, SCC_NAME=}, CUSTOMER={GEO_LINK=, CUST_NAME=, CUST_ID=, CUST_ADDR=}}, JOB_ID=, TRANS_SRC=, TRANS_DEST=}, MR_POOL={FREE_MR=, BUSY_MR={77889992222={IS_BUSY=false, GEO_LINK=8yyttrd}}}} }

From the attached input it seems that there is only one entry in the map with key platformdb and value as MR_RELATIONS=....

If you are doing String MR_ID = map.get("MR_ID"); then it will probably return you null as there is no entry in the map with key MR_ID.

What you should be doing instead is retrieve the value against the key by doing the following:

String response = map.get("platformdb");

And then parse this response String to extract the desired values.

Since, response does not seems to be JSON you can try using native String functions.

For example, to extract MR_ID from response you can do the following:

String response = map.get("platformdb");
String MR_ID = response.substring(response.indexOf("MR_ID=") + 6,
                                  response.indexOf("MR_ID=") + response.indexOf(","));
String Delv_ADDR = response.substring(response.indexOf("Delv_ADDR=") + 10,
                                  response.indexOf("Delv_ADDR=") + response.indexOf(","));
