Use the String's equals() method instead of the == operator for comparing strings:

info.activityInfo.applicationInfo.loadLabel( pm ).toString().equals(appName)

In Java, one of the most common mistakes newcomers meet is using == to compare Strings. You have to remember, == compares the object references, not the content.
