inside onactivityresult creating bitmap object instead of using declaring @ class level remove second declaration of bitmap:
try { //bitmap bitmap; << remove bitmapfactory.options bitmapoptions = new bitmapfactory.options(); bitmap = bitmapfactory.decodefile(f.getabsolutepath(), bitmapoptions); .... code
