Getting App Version Number

This tutorial is to get the application version no. For this purpose we will be using PackageInfo.

     PackageInfo pInfo = null;

     String strVersion;

    try
    {
        pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
    } catch (NameNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    strVersion = pInfo.versionName;
