Android Question Exeption occured - Problem with Setup B4A v7.3 and v7.8

[manuel-r]

Hi together

I've reinstalled my notebook. So I had to reinstall B4A and all needed components too. While installing no errors occured. But when I run B4A I get an error message that says the following.

With B4A 7.3:
"An error occured. Der Typeninitialisierer für 'dx' hat eine Ausnahme verursacht."

With B4A 7.8:
"An error occured. Der Typeninitialisierer für 'd6' hat eine Ausnahme verursacht."

Yes, there ist english and german (?!). I think in english it means "The type-initiator for 'dx' caused an exception."

The second thing is, that I can't save the configuration under "Tools > Configure Paths". I get the error "Error occured. Error saving ini file"

The environment is: Windows 7 Pro x64, JDK8 Build 162 x86, Android SDK 25.2.5

Can anyone help me?

Greetings from very windy Germany ;-)

Did you updates your net framework?
Version 4.5+ is required or so...

Windows Vista+: .Net Framework 4.5.2.

 

[manuel-r]

I've installed NET Framework 4.7.1
That's above 4.5 so I think this is ok.

 

[DonManfred]

yes, should be ok.
You did setup the SDK with the new B4A SDK Manager?

 

[manuel-r]

Ääähm. No, I didn't. First I installed JDK, then SDK an finaly B4A.
Should I reinstall SDK over B4A?

 

[manuel-r]

In B4A v7.3 (actually this is installed) there is no SDK Manager.
But I think the error does not depend on SDK. I think it comes from the development platform B4A is written with. Maybe I need some ressources?!

In B4A v7.3 (actually this is installed) there is no SDK Manager.

The old Android SDK Manager is deprecated. Use the SDK Manager and setup a new SDK in a new folder.

In B4A 7.8 the SDK Manager is integrated in the IDE

 

[DonManfred]

Try to enable ide logs and see whether there is any error message there: https://www.b4x.com/android/forum/posts/50478/
Post the result here

 

[manuel-r]

That's crazy. The log sais

Build modules tree: 0
B4A version: 7.80
.Net version: 4.0.30319.42000
System.TypeInitializationException: Der Typeninitialisierer für "d6" hat eine Ausnahme verursacht. --->

but I have installed NET Framework 4.7

I tried to install NET 4.5.2 but that's not possible 'cause I have installed a higher version yet. So why sais B4A that there is only NET 4.0 installed?!

 

[DonManfred]

Try remove the V4.7 and then add the 4.52
Add 4.7 after 4.52 is installed

Sometimes you have to do strange actions to fix Windows' issues. I'm getting many calls from customers that after an update are no more able to operate with USB/RS232 converters. Old Prolific hardware won't work any more. But they point finger to my CNC part program manager, working from 18 years!

 

[manuel-r]

I tried it.
First I uninstalled NET Framework 4.7.1 and installed NET Framework 5.2. After that B4A runs correctly.
Then I installed NET Framework 4.7.1 again. Since that B4A doesn't run and gives the same error as described above

@Erel:
Some hints about this?

 

[manuel-r]

Is ist possible, that the B4A-Executable detects the NET-Version by an incorrect way?
In https://docs.microsoft.com/de-de/do...-determine-which-versions-are-installed#net_b I found how to get the installed version via the registry. So in my case it says Release 461310 under HKLM\SOFTWARE\NET Framework Setup\NDP\v4\Full. This release 461310 means that NET 4.7.1 is installed. But if I look into the InstallPath then this Path contains v4.0.3019 and this ist exactly the version that is logged in the logfile when the error occurs.

Read this (solved) post: https://www.b4x.com/android/forum/threads/solved-im-unable-to-start-b4a.88311/

- I have found a problem: Update for Microsoft .NET Framework 4.7.1 (KB4055002), after uninstalling this update, B4A is starting again, ask for license... everything work fine now.

 

[manuel-r]

Yes, but that can't be the final solution.

 

[Erel]

Yes, but that can't be the final solution.

This is Microsoft fault...

I hope that they will soon release a new update.

Looks like they already did release a patch: https://support.microsoft.com/en-us...lup-for-net-framework-3-5-1-4-5-2-4-6-4-6-1-4
