greetings i'm trying develop activity in app user captures image using photographic camera , save custom folder in gallery here code i'm using

it captures image , creates folder , image file in image blank flat black, can help me that

you not saving jpeg buffer info onto file, creating directories within isdir , creating file there extension jpg fout = new fileoutputstream(file); not saving image contents

edit here how can save info file

string filename = system.currenttimemillis() + ".jpg"; file directory = new file(environment .getexternalstoragepublicdirectory(environment.directory_pictures), "xyz"); // save jpeg info disk boolean success = true; seek { if (!directory.isdirectory() && !directory.mkdirs()) { throw new ioexception("unable create directories path " + directory); } file file = new file(directory, "ge_" + filename); fileoutputstream fout = new fileoutputstream(file); fout.write(data); fout.close(); mediascannerconnection.scanfile(cameraactivity.this, new string[] {file.getabsolutepath()}, new string[]{"image/jpg"}, null); } grab (ioexception e) { e.printstacktrace(); }
