Firstly the plant looks much more glabrous than expected.
Secondly the taxonomy of Solanum indicum L. is very complex. One thing is sure, Solanum indicum L. can't be used as name, as it has been listed as rejected name in 2006 publication of Botanical Code. Now what are the possibilities for our plants of S. indicum. According to GRIN taxonomy page S. indicum L. is now S. lasiocarpum Dunal, whereas S. indicum auct. is S. anguivi Lam. According to Eflora of China S. indicum L. is synonym of S. violaceum Ortega. Eflora of Pakistan prefers S. anguivi for S. indicum. Here is the key for three species that we should keep in mind while sorting specimens of S. indicum L.
Solanum lasiocarpum Dunal: Leaf 10-20 × 8-18 cm ;Corolla white; Fruit densely stellate, 2 cm, orange; calyx lobes nearly leaflike, 8-10 mm long
Solanum violaceum Ortega: Leaf 5-11 × 2-8 cm; Corolla blue-purple, sometimes white; Fruit glabrous, 8-13 mm, shiny orange; calyx lobes not leaflike, mostly less than 7 mm.
Solanum anguivi Lam.: Leaves 4-15 x 3.5-9 cm; lowers bluish purple; Fruit 8-10 mm, glabrescent, yellow;calyx lobes not leaf-like, nearly 4 mm
So barring more glabrous plants, your plant should be S. violaceum. Berries appear glabrous to me. You may please check on above features and decide.
