Android中base64加密后的字符串带有“\n”导致出错的

Android 解密 

byte[] aa = Base64.decode(str, Base64.DEFAULT);

bitmap = BitmapFactory.decodeByteArray(aa, 0, aa.length);

Base 64 加密 

ByteArrayOutputStream baos =new ByteArrayOutputStream();

bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);

byte[] result= baos.toByteArray();

String str2 = Base64.encodeToString(result, Base64.NO_WRAP);
