Android Question What is this error? (parse error)

[vecino]

Hello, after several months and having changed version of B4A, I went to make a change in a small project I have and my surprise was that it does not compile and shows the following error:
What can I do?
Thank you.

First result.

Hello, yes, I have been searching and reading different cases and I haven't found anything that works for me.
In theory it seems to be because it has been compiled with a newer version of java, but I haven't changed the java version, I still have the same one.
Thank you.

Which libraries are you using?

 

[vecino]

Hello, this project uses these libraries:
Thank you.

As an aside you should be using the Dialogs2 library and the async versions of those dialogs.

Dialogs2 library - an update to the original Dialogs library

Note the separate download for an updated Dialogs2 class that fixes a bug in the original. I wrote the original Dialogs library many moons ago and it has suffered with age owing to the changes made to Android and B4A over the years despite the administrations of several other people. Although...

Also Reflection is now supplied as an internal library so you should delete it from your additional libraries.

Hello, I was not aware of the existence of "Dialogs2". I have changed it and the problem persists.
Reflection is internal, what do you mean?
Thank you very much.

They are now like this:

Reflection is internal, what do you mean?

What I said. It is now supplied as an internal library like JavaObject and is (or should be) in ProgramFiles(x86)\AnywhereSoftware\Basic4android\Libraries.

I was not aware of the existence of "Dialogs2

You must have forgotten! ? Getting old like me?

Dialogs2 library always returns day 1 of the month

Hi, I'm testing the "Dialogs2" library and something strange is happening. Whatever date I select, it always returns the 1st of the month. Example, today is 06.10.2021 and I touch a label that opens the dialog window to choose date, I select any day of any month and accept. The result returns...

I've lost my head! Maybe it's senile dementia, I didn't remember that. Sometimes I even have doubts and I do a search and I discover that I had already asked that question before and I had solved it. I think I need to worry about that

Reflection is marked as internal, you're not talking about another library?
Thank you.

My turn to lose my head.! I was sure that it was marked Additional in your original screenshot.

unsupported class file version 53.0
...while parsing META-INF/versions/9/module-info.class

It definitely looks like one of the additional libraries was compiled with Java 9. Try omitting them one at a time if you can to find out which one is causing the problem.

unsupported class file version 53.0 ...while parsing module-info.class

I have a friend who is wrapping a library. It compiles fine with SLC, loads fine in B4A but when compiling in B4A, the following error appears: Convirtiendo byte code a dex optimizado. Error warning: Ignoring InnerClasses attribute for an anonymous inner class...

[vecino]

All this must be the fault of age
The years are unforgiving

 

[vecino]

I have tried removing "Archiver" and the error is the same.
The other remaining additional library is "ScrollView2d" which is used by the "Flexible Table" class.
I created a new project with that class and there is no problem either.
And there are no more additional libraries, everything else is internal.
I'm lost.

 

[vecino]

Oh!!! I am trying to compile all my projects and some, a few, work, but the rest all give the following threatening, disturbing, disturbing, creepy error....
All this happens since I installed the latest version of B4A, can it have something to do with this?

Have you tried installing a new SDK? I believe B4A 11.2 requires an up to date SDK. Put a new one in a different folder, point B4A at it and see if it works then.

com.jcraft.jsch.Channel that it is complaining about is Java Secure Channel which is a Java implementation of SSH2. I don't know if it comes with the SDK or is in one of the B4A internal networking libraries.

Yes I installed that new SDK version together with the new B4A as well

 

[vecino]

I'm going to try the previous version, I didn't delete the SDK, I renamed it. But I did delete B4A, where can I get the previous version of B4A to test?

 

[agraham]

But I did delete B4A, where can I get the previous version of B4A to test?

I don't think it is available anywhere on the forum. Can you post a small project that fails?

 

[vecino]

I've been doing a lot of testing to make sure and this is the result:

I found v11.00 in a backup.
And using that v11.00 and the SDK before the one currently available for download on the web, everything compiles fine.

I have also tried v11.00 and the new SDK that is now on the web for download and it works fine.

The problems start only when I install the latest version of B4A.
