    byte[] bytes2 = new byte[size];
    Array.Copy(bytes, bytes2, size);
    AndroidDecompress decompress = new AndroidDecompress();
    String content = decompress.decompressXML(bytes);
    String regex = "package \\{color: (#(\\d|[a-f]){6};)}";

    Regexes *might* be adequate for a fixed-form XML like yours seems to be, but you'll do yourself a favor if you just use a XML parser. – hugo Aug 06 '19 at 08:56

    It seems like normal Xml format so you shoud work with it as with xml. – Erik Šťastný Aug 06 '19 at 08:57
  • Since its a XML you should be able to write a simple xml parser. See this [XmlParser](https://stackoverflow.com/questions/55828/how-does-one-parse-xml-files) – KJSR Aug 06 '19 at 09:36
  • If you want a package name then it is already written in your MANIFEST file. package=\"com.auditapp.securemeters.code\ – virusarthak Aug 06 '19 at 11:09
