how replace data php textview in application?

the problem is, trying value out of nested jsonobject directly without 'walking' way down.

since jsonobject looks this:

{'online': [              {'total online': '3',....}            ],  'success': 1 } 

you have do

jsonobject obj = jparser.makehttprequest(url_all_products, "get", params); string totalonline = obj.getjsonarray('online').getjsonobject(0).getstring('total online'); 

note, here i'm chaining functions. step step - if need reuse 1 of items:

jsonobject obj = jparser.makehttprequest(url_all_products, "get", params); jsonarray online = obj.getjsonarray('online'); jsonobject firstonlineobject = online.getjsonobject(0); string totalonline = firstonlineobject.getstring('total online');
