What do you mean?
As Manfred told you a few posts above, we're working on a new project.
The lib part of it will be something closer to the service active in Google's PlayStore: something that from device boot looks for eventual upgrades of listed apps and then sends notifications letting the user to decide what and when to upgrade/install.
Maybe to solve your problem you don't need the whole stuff, but just a few pieces to re-assemble at your will.
I see a scheme like:
1. Device boot
2. "Special" app launches itself and discovers apps to be updated (in your case, no notification is needed)
3. for each app which has a newer version the "special" app downloads the apk and sends the appropriate OS Intent
4. the user (medical staff or anyone working at that office) accepts or denies updates
5. on "special" app termination you set the Kiosk Mode and launch the app with which the patients operate
Could this work for you?

Hi DonManfred,or all
I've interested this thread for a long time,I've just found how to set my own web server as localhost.
I have 2 problems to ask you.
1.) I use phpThai as webserver alike xampp,I've done,but I can't set the tablet link to the web server(I use win8 32 bits as web server) How to set my windows8 for this connection?
2.) In your post11 ,I get your example,inside of txt file (it means as the attached picture ) ,Should I write something in it?

You dont need to change your network-card-settings! At the time you can see something like on your MyWebServerPic.jpg you are ready
The process of the webserver (phpthai?) should have access to internet through your firewall... But if it has access then you should be able to call your phprhai from your app
You want to use YOUR PC as server, yes?
look what Internet-IP you have... For example if your internet-ip is 123.12.34.45
then the adress to apk in your app should look like http://123.12.34.45/b4a/apk/TestAnchor.apk
BUT. The most people dont have an static (not changing) IP-Address.. So, this ip could have an other value when you restart your computer...
In that case you app can not reach your computer cause of ip-address changes... Maybe your computer now have
123.12.34.92 as ip and your app dont know this adress. So it runs into a not found error...
The new apk-url is http://123.12.34.92/b4a/apk/TestAnchor.apk now
Best way is to have an small webhosting at some webspace-provider beside a domain... an IP from an domain useually dont change.
You then just upload your txt and apk file to your webspace and then, in your app, you set the path to
http://myowndomain.tld/b4a/apk/TestAnchor.apk
when your registered domainname is "myowndomain.tld"

Your ip 192.168.1.3 is your LAN(1)-IP-Address.
Your APK should be able to reach this address if your device is in your WIFI.
If the device is using internetconnection NOT YOUR WIFI... e.g. a internetprovider,,, THEN you must use your WAN(2)-IP-Address you got from your internetprovider..
Call the url http://www.wieistmeineip.de/ from your pc... The big IP in the top is your WAN-IP
Use this ip in your app in url...
(1): LAN LocalAreaNetwork (your router, your pc, any device who connects to your router)
(2): WAN WideAreaNetwork (anything else (not in LAN)... THE INTERNET)
In you router (the one under 192.168.1.1) for example you should somewhere see your WAN address... THAT´s the ip you should use in your app

Ok, again.
Call this url from your PC please: http://www.wieistmeineip.de/
in my case i can see
Look what you can see.... THIS (the one YOU see when calling the url i provided) IP you should use in your app

Have you tried to call http://125.26.84.96/b4a/apk/ from your PCs Webbrowser?
If that work it should work from your app also. If that not work then the problem seems in your firewall and/or antivirus.
Maybe the port 80 is not open from your firewall?

If you have an router then the problem could be there.
Look in your routers manual how to configure a portforwarding.
pubic port: 80
local port: 80
ip: 192.168.1.3
type: TCP
Test it with your pcs webbrowser. It must show the same as your localhost/b7a/apk/ call...

what´s the content of "http://xxxx.net/xx/v.txt"? For a version of 1.50 it must be
Maybe there are more infos in the log about this error? Maybe a line of code where the exception happens
BTW: In the code you posted i cannot see anything what could give an StringIndexOutOfBoundsException...

AppUpdating version 1.25 is finally released!
Attached to post #1 you may find three new zip files:
- AppUdating_125.zip: updated lirary fles; just copy to your extralib dir and you're ready
- AppUpdating_125_src.zip: source code to library files
- AppUpdating_125_ex: example app showing lib usage
Unfortunately version 1.25 breaks existing code. Sorry guys.
A few variables are gone and even the main sub changed its name, but now everything appears more coherent to me and easier to maintain.
ChangeLog
To set credentials to access a protected folder on webserver you now have a new function: setCredentials(Username, Password).
Properties sUserName and sUPassword are no longer directly reachable.
NewVerAvailable var is no longer available
IsDone function is no longer available
LookForNewerVersion function changed its name to UpdateApk
Added costants for Error codes and Status codes
Added property sVerbose; setting it to TRUE makes logs mode veeery verbose
Previous sub GetCurVN is now ReadCurVN
Added newer and different function getCurVN to be coherent with getWebVN
Now you're expected to call the Readxxx functions first and on their completion call the getXXX counterparts.
Added step-by-step function: ReadCurVN, ReadWebVN, DownloadApk, InstallApk
So now you could call UpdateApk which does all the work in a single rush or call each of the above functions to retain more control over the process.
You are encouraged to have a look at the example code where any feature is used.
Once again, sorry for any inconvenience this update may cause to you.
