After completion of execution of an activity i want to make jSONArray empty or delete it. Because when i am calling the activity repeatedly the new data gets append to the old data present in JSONArray. My jsonArray is as shown below..
[{"record":[
            {......},
            {.......}
           ]
 },
 {"record":[
            {..........},
            {.........}
           ]
 }
] 
First time:
[{"record":[{"intensity":"Low","Body_SubParts":"Scalp","symptom":"Bleeding"}]}]
Second time:
[{"record":[{"intensity":"Low","Body_SubParts":"Scalp","symptom":"Bleeding"},
{"intensity":"Low","Body_SubParts":"Eyes","symptom":"Bleeding"}]}]
