Android getPackageInfo without getPackageManager

Is there any possibility to get the versionCode of an App without the getPackageManager? My Problem is, that i want a public Configuration class which have no Activity, so the getPackageManager() does not work. Any Idea?

My current Code:

PackageInfo pinfo;
try {
    pinfo = getPackageManager().getPackageInfo(getPackageName(), 0);
} catch (NameNotFoundException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
    pinfo = null;
}

appVersion = pinfo.versionCode;

Use the following code to get app version code of the current app:

public int getAppVersionCode() {
    return BuildConfig.VERSION_CODE;
}

Take an instance of Context in the constructor of your non-activity class and use that to call all such methods.

Something like this:

public class NonActivityClass implements SensorListener{
Context mContext;
public NonActivtiyClass(Context context) {
this.mContext = context;
}
//Rest of your code
}

Then do this to create an object of that class in your Activtiy's onCreate():

NonActivityClass nac = new NonActivityClass(this);

You'll have to pass a reference to the Context (preferably using getApplicationContext(), to prevent accidental memory leaks) to the public Configuration class. There is no other way to retrieve the versionCode of your application. You have to use PackageManager.
