LAMW can I read versionName and versionCode programmatically?

I'd like to be able to read the values of android:versionName and
android:versionCode (assigned in AndroidManifex.xml) from within my
LAMW app.

Is it possible?

If possible use the functions:
self.GetVersionCode() and self.GetVersionName()

I don't see those functions anywhere. What class of object is "self"
in your example?

I only see some code used in the IDE integration, where you can assign
values that will be written in AndroidManifest.xml

But I'd like to be able to read those values at runtime, from within
the app itself.

Right now I'm using a round-about way: I wrote a utility that runs
before compilation, reads the values from the manifest file, and
patches those values as constants in an include file, which will be
compiled with the app. The app then gets the information from those
constants.

However I think it would be nice to have a way to just access that
info from e.g. a jForm object, like in the case of various other
environment-related variables such as package name, internal app
directory, etc.

Hi ADiV,

I was just checking the code in Controls.java, I have found a shorter
alternative, possibly returns the same thing I guess.

Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i public
String getVersionName() {    return BuildConfig.VERSION_NAME;} public
String getVersionCode() {   return
String.valueOf(BuildConfig.VERSION_CODE);}

These functions belong to the "jForm" class. I created them myself and
included them in LAMW not long ago, maybe you don't use the latest
version they are included in. Hence, belonging to jForm, I call them
using self.GetVersionCode ()

For example, I use this feature in my latest QRiBar Scanner app:

The current implementation is the safest:
Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i // By ADiV 
      public int GetVersionCode(){                PackageManager pm =
controls.activity.getPackageManager();                            try
{                PackageInfo pinfo =
pm.getPackageInfo(controls.activity.getPackageName(), 0);            
  return pinfo.versionCode;            } catch (NameNotFoundException
e) {                return 0;            }        }         //By ADiV 
      public String GetVersionName(){                PackageManager pm
= controls.activity.getPackageManager();                           
try {                PackageInfo pinfo =
pm.getPackageInfo(controls.activity.getPackageName(), 0);            
  return pinfo.versionName;            } catch (NameNotFoundException
e) {                return "";            }        }

Thanks everyone, I was using a slightly older version, I see it now!
