getpackageinfo. Versionname
}
//Version number public
static int Getversioncode (context) {return
getpackageinfo. Versioncode
}
private static PackageInfo Getpackageinfo (context context) {
PackageInfo pi = null;
try {
Packagemanager pm = Context.getpackagemanager ();
Pi = Pm.getpackageinfo (Context.getpackagename (),
packagemanager.get_configurations);
return pi;
} catch (Exception e) {
e.printstacktrace ();
}
return pi;
}
