I am using an edited version of:

B4A Library - AppUpdating - automate apps updating from a webserver

Hey I never got around to it as it really wasnt causing a problem. But, the new B4A 6.80 release breaks your library. its completely broken. Error: LogCat connected to: HA0N5DDN --------- beginning of system --------- beginning of main --------- beginning of crash main_update_updatecomplete...

I am running the example in Post #243
The Example app runs great.
However, when I port it over to my main app, I get the following error:
B4X: 
---- AppUpdating.UpdateApk
    Current Version: 1.00
*** Service (httputils2service) Create ***

    -- JoWebVNcompare
    Read while in webVNcompare: ver=1.01
    Web version number: 1.01
    Newer version available. Now I try its downloading

I have checked the Manifest and this is in:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

so, I don't know what is causing the erroe.

You are missing different things.

See this Tutorial:

Version safe APK installation

As explained in this tutorial all store apps will soon be forced to target the latest SDK. This means that we can no longer rely on the OS backwards compatibility features and need to handle the behavior changes ourselves. Starting from Android 8 (API 26) each app needs to explicitly request a...

Hi Declan,
any reason to prefer old AppUpdating to its 2.0 version?
Btw, if you follow post#34 of AU2.0 you find version 2.04 that proved to work with Android 8 and 9
Sorry if I am unable to give you direct links as of now because I'm using my mobile while walking..

I have AU2.0 somewhat running.
I can check and download the new app from the server.
I then install:
"Google Play Protect"
Click "Allow"
"Installing"
"App Installed"
Now when I click "Open" the app crashes.
This is a small part of a bigger app.
I have attached the ZIP as I cannot fathom what is wrong

Hi, could be an interference due to Google Play Protect?
Can you temporaly disable it and verify if the updated app gets relaunched automatically? That won't solve your problem, but will tell us that AU2 is working properly.
Since I don't use GPP, is there any option to configure apps as "secure", excluding them from its inspection? I read that you allow the installation but what if GPP finds something that it doesn't like? Would it stop and crash the app, show a message or what?
BTW, looking at you code I can't spot a specific reason why the final step fails.

@udg Many Thanks
I have made some progress and will try your above recommendation soon.
After I have downloaded the new app with AU2.0, and then reload the app (from the Home Page icon) it runs and all functionality of the app is OK.
However, if I then retry the AU, the app crashes and I get the following error on my Android device:
B4X: 
android.content.pm.PackageManager$NameNotFoundException: b4a.example.appupdate

I cannot understand: "android.content.pm.PackageManager$NameNotFoundException: b4a.example.appupdate"
as my app name is "com.rob.leadguru" and NOT "b4a.example.appupdate"

Really strange. It looks like it downloads and installs a "debug" copy of your app from your server.
No, it seems to refer to my demo app.
Check what's on the server. As for testing, I generally put on my server the same app I'm going to test, wher its version number is changed to look newer. Even quicker way: just configure the info file to show a newwer version is ready but keep on server an exact copy of the app under test (useful just to see that the whole process gets completed)

Ok, found the initial problem - I had an edit version of your example on my server.
That has now been resolved, but still crashes on "Open" after Install and does not install the new downloaded version.

Did you try the "suspend Google Play Protect" hint? Did it fail?

Isn't it a separate feature/app installed from the PlayStore? If yes, probably you may find it among the "installed apps" and eventually look for an option to temporaly suspend it or to tell it to disregard your specific app.
I'm sorry to be of little help here, but as said I don't use GPP so I can just offer guesses. Hope someone knowing it better could give us more infos.

Ok, so we're back to square one: problem is with AU and/or your code.
I'm reading your Starter service. You seem to call readUser a lot of times when the app starts (and each time you initialize the DB).
Why not initialize the DB once and call readUser/Notify/Leads once? You can keep the if/then to show proper log message.

Ok, I am now using a brad new Samsung Note 10 and I have the same problem.
The APK downloads from the server and after "Installing" I get a message "Not Installed".
Maybe a guess is that the
APK is not downloaded correctly?
I have cleaned-up the app as mentioned in your previous post.
Latest app is attached.
