I have tried many thinking like - JsonArray test = new JsonArray(), JsonArray test("[]");

but nothing is working can some one help me in solving this.

Answer 1

You need to run a while loop across the length of the test and at each time delete the first index. the loop will reach a stage when the length of the test is zero to show the test is not empty and and cleared.

while (test.length() > 0) {
        test.remove(0)
}

Answer 2

Try this for clearing JSONArray:

jsonArray = new JSONArray(new ArrayList<String>());
