Android, How to retrieve the image previously save and display when required -


i used code below save image taken camera intent, folder in gallery, worked great. i'd retrieve image display on imageview within activity when asked, though after trying various methods/code, nothing far has worked. given path/code used save image, point me in right direction of how back. in advance - jim.

public void saveimage(context context,bitmap imagetosave, string filename){      thethis = context;      string file_path = environment.getexternalstoragedirectory()+ nameoffolder;     // string currentdateandtime= getcurrentdateandtime();      file dir = new file(file_path);       if(!dir.exists()){          dir.mkdirs();      }       file file = new file(dir, filename + ".jpg");       try {          fileoutputstream fout = new fileoutputstream(file);          imagetosave.compress(bitmap.compressformat.jpeg, 100, fout);          fout.flush();          fout.close();          makesurefilewascreatedthenmakeavabile(file);          abletosave();       }       catch (filenotfoundexception e) {unabletosave();}      catch (ioexception e){unabletosave();}          }   private void makesurefilewascreatedthenmakeavabile(file file) {      mediascannerconnection.scanfile(thethis,              new string[] { file.tostring() }, null,              new mediascannerconnection.onscancompletedlistener() {          public void onscancompleted(string path, uri uri) {              log.e("externalstorage", "scanned " + path + ":");              log.e("externalstorage", "-> uri=" + uri);           }      });   }

if have proper path , permissions, here code working me

file rootsd = environment.getexternalstoragedirectory(); string rootpath = rootsd.getabsolutepath(); string pathname = rootpath + "your path here" + "image name here";  try {            drawable d = drawable.createfrompath(pathname); layout.setbackgrounddrawable(d); } catch (exception e) { e.printstacktrace(); }

hope helps , enjoy work.
