Android canvas save always java.io.IOException: open failed: ENOENT (No such file or directory) -

i have canvas application. i'm trying create signature app canvas + ontouchlistener.

this save method, try save signature image:

private void save() {     hidemenubar();     view content = this;     content.setdrawingcacheenabled(true);     content.setdrawingcachequality(view.drawing_cache_quality_high);     bitmap bitmap = content.getdrawingcache();     string path = environment.getexternalstoragedirectory().getabsolutepath();     string imgpath = path+"/imotax/capture/spop/ttd/image" + "temp" + ".jpg";     file file = new file(imgpath);     fileoutputstream ostream;     try {         file.createnewfile();         ostream = new fileoutputstream(file);         bitmap.compress(compressformat.jpeg, 100, ostream);         ostream.flush();         ostream.close();         toast.maketext(getcontext(), "image saved", 5000).show();     } catch (exception e) {         e.printstacktrace();         log.i("ttd", e.tostring());         toast.maketext(getcontext(), "failed save", 5000).show();         showmenubar();     } } 

i don't know why, errors or enters catch statement error:

java.io.ioexception: open failed: enoent (no such file or directory) 

try way

private void save() {         try {             hidemenubar();             view content = this;             content.setdrawingcacheenabled(true);             content.setdrawingcachequality(view.drawing_cache_quality_high);             bitmap bitmap = content.getdrawingcache();              string extr = environment.getexternalstoragedirectory().tostring();             file mfolder = new file(extr + "/imotax/capture/spop/ttd/image");             if (!mfolder.exists()) {                 mfolder.mkdir();             }              string s = "tmp.png";              file f = new file(mfolder.getabsolutepath(), s);              fileoutputstream fos = null;             fos = new fileoutputstream(f);             bitmap.compress(compressformat.jpeg, 100, fos);             fos.flush();             fos.close();              bitmap.recycle();              toast.maketext(getcontext(), "image saved", 5000).show();         } catch (exception e) {             toast.maketext(getcontext(), "failed save", 5000).show();         }     } 

update

file mfolder = new file(extr + "/imotax/capture/spop/ttd/image");  //replace  file mfolder = new file(extr + "/imotax");
