android 4.0 , later support wifi direct. however, of 4.x devices not support because of wifi driver.

to overcome problem need check device supportable wifi direct or not. checking use code:

objmanager.discoverpeers(objchannel, new actionlistener() {     @override     public void onsuccess() {         //onsuccess     }     @override     public void onfailure(int reason) {         //onfailure     } });
