Question

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;

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);
