bitmap bitmap=bitmapfactory.decodefile(imagepath);

this has 2 parameters, 1 imagepath , other 1 object of bitmapfactory.options. try out adding following lines.

            bitmapfactory.options bmpfactoryoptions = new bitmapfactory.options();             bmpfactoryoptions.injustdecodebounds = true;             bitmap bitmap = bitmapfactory.decodefile(imagepath, bmpfactoryoptions);
