android - How to delete file from storage -

i have content menu pop menu of rename , delete when press item in few seconds. dont know how correct directory of 1 file. here code:

@override public boolean oncontextitemselected(menuitem item) {     adapterview.adaptercontextmenuinfo info = (adapterview.adaptercontextmenuinfo) item.getmenuinfo();     switch(item.getitemid()) {         case r.id.rename:             // edit stuff here             return true;         case r.id.delete:              file dir = new file(environment.getexternalstoragedirectory()+"/music/musicplayer");             if (dir.isdirectory())             {                 string[] children = dir.list();                 (int = 0; < children.length; i++)                 {                     new file(dir, children[i]).delete();                 }             }              // remove stuff here             return true;         default:             return super.oncontextitemselected(item);     } } 

use below util function either delete file or directory.

public static boolean delete(file path) {     boolean result = true;     if (path.exists()) {         if (path.isdirectory()) {             (file child : path.listfiles()) {                 result &= delete(child);             }             result &= path.delete(); // delete empty directory.         } else if (path.isfile()) {             result &= path.delete();         }         return result;     } else {         return false;     } } 

usage:

file dir = new file(environment.getexternalstoragedirectory()+"/music/musicplayer"); delete(dir);
