Android delete all files starting with particular word -



Android delete all files starting with particular word -

i have problem , hope can help me out.

in wallpaper app, saving image sdcard user can share online via actionbar share function.

here code saving:

uri bmpuri = null; seek { file file = new file(environment.getexternalstoragepublicdirectory( environment.directory_downloads), "share_image_" + system.currenttimemillis() + ".png"); file.getparentfile().mkdirs(); fileoutputstream out = new fileoutputstream(file); bmp.compress(bitmap.compressformat.png, 90, out); out.close(); bmpuri = uri.fromfile(file); } grab (ioexception e) { e.printstacktrace(); } homecoming bmpuri;

now, trying delete image when user leaves activity (which means shared image or decided not share. either way, not needed anymore.)

i trying delete code (its on button click method atm, alter later)

case r.id.btn_delete: // file folder = (environment.getexternalstoragepublicdirectory(environment.directory_downloads)); file folder = new file(environment.getexternalstoragedirectory() + environment.directory_downloads); file[] filenamestemp = folder.listfiles(); (int = 0; < filenamestemp.length; i++) { if (filenamestemp[i].getabsolutepath().tostring().contains("share_image_")) filenamestemp[i].delete(); } break;

the way see it, should work...but doesn't.

i tried sorts of things, nothings works. no errors,nothing..but image still nowadays in downloads directory.

any help?

i think getting wrong directory written files

you reading files by

file folder = new file(environment.getexternalstoragedirectory() + environment.directory_downloads);

instead of:

file folder = (environment.getexternalstoragepublicdirectory(environment.directory_downloads));

these directories not same.

hope helps, if need else tell me ;)
