lz solve this problem?

android does not remove the JSONArray this method. But net.sf.json.JSONArray there. . .

Some people say that you can use the put (index, null) to achieve, but it will generate a null data in the JSONArray

remove method is very unique to the new version of the SDK is compatible considered, or do not call.
Can be achieved with a third-party library, or on their own copy of the new JSONArray, remove the key to be deleted
