Try this:

    String s = "name=pkgname -path=some.apk -minutes=120";
    Pattern p = Pattern.compile("name=(\\w+)");
    Matcher m = p.matcher(s);
    if (m.find())
        System.out.println(m.group(1));

What is the java regex to match only "pkgName" from string:

You can use a positive lookbehind:

(?<=name=)\S+
  • (?<=name=) is positive look-behind to assert that previous position has name=
  • \S+ will match 1 or more non-space characters

Using Java:

public static final Pattern PKG_NAME_REGEX = Pattern.compile("(?<=name=)\\S+");

Repace the dot by word character:

"(name=)(\\b\\w+\\b)\\s"

and the word boundaries are not usfull here:

"(name=)(\\w+)\\s"
