change root path :

root = new file(environment.getexternalstoragedirectory() + file.separator + "android/data/com.goldenedge.poetry" + filecatpath);

to :

    root = new file(getfullfilepath(environment.getexternalstoragedirectory()+"/android/data/com.goldenedge.poetry/urdu/festive poetry","4__311159_248676158509124_848180994_n.jpg "));   public string getfullfilepath(string filepath,string filename) {          file dir = new file(filepath);         if (!dir.exists()) {             dir.mkdirs();         }         return filepath + filename;     }

use method check directory isexist() or not, there many devices invalidated file name special characters give invalid arguments error.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
