Android Question Error building app bundle (Win11Pro, B4a 11.80)

bigbadfred · Oct 23, 2022

I am having a hard time finding a solution for the following error that occurs when trying to build an app bundle:
Module files can be only in pre-defined directories, but found 'libs/android-support-v4.jar

Error building app bundle:

My application compiles fine, I deploy it via Bridge to my phone, no problem.
I am using Windows 11 Pro, B4A 11.80 & sometimes NOX to test different resolutions.

Fixes that I have tried, but that didn't solve the problem:
- TargetSDK=31 (Changed it to 30 & 29, no change)
- Re-installed Java, extracted all the necessary Android archives, to no avail.
- Removed android-support-v4.jar out of my additional libraries folder, no luck
- Tried to fix it with SDK-manager, which gives me an extra error: Error reading recommended items list

Socket error:

B4A Sdk Manager: 4.00
TempFolder = C:\Users\bigba\AppData\Roaming\ANYWHE~1\BASIC4~1\temp
DataFolder: C:\Users\bigba\AppData\Roaming\B4ASdkManager
SDK version: 6609375
Downloading: https://dl.google.com/dl/android/maven2/master-index.xml
error: java.net.SocketException: Connection reset by peer: socket write error

Can anybody help me with this?

You have to delete your SDK folder and configure a new one.

Hi, thanks for your reply.
Unfortunately that didn't work.
Deinstalled and reinstalled Oracle Java 8, didn't work.
Deinstalled Oracle Java 8 and installed OpenJDK 11 also didn't work.
I have the impression it has something to do with the BundleTool, but I have no clue what that might be.
Perhaps "android-support-v4.jar" needs to be placed somewhere else?
I also tried that, didn't work out as well.

Delete your current sdk and setup a new one as described here: https://www.b4x.com/b4a.html

Note that SDK folder is not the java folder it’s android SDK folder.

Hi, I did. I deinstalled and reinstalled all the executables & zip-files as described here: https://www.b4x.com/b4a.html

Didn't change a thing :-(

Unzip the archive preferable with 7zip, I hope you did that too

Also, your folder Android sdk path should not be a restricted path or path with spaces. Its advisable you put it on the C drive.
And Do not update the SDK after downloading

I specially downloaded 7-zip for that, even though Winrar works as well.
I did that just now again, did NOT run the SDKManager and still doesn't work.
Android SDK is extracted to c:\Android\, OpenJDK is extracted to c:\Java\jdk-11.0.1\.
The app compiles fine, installs perfectly on my cellphone (release and release obfuscated), it just does not want to build that app bundle.

Physically check your <android sdk>\tools\bin folder to see if bundletool.jar is present

Also, redownload new B4A IDE and install

Bundletool.jar is present in C:\Android\build-tools\
Installed the latest b4a half an hour ago, still doesn't work.....
I'm banging the wall with my head in frustration, nothing seems to work.

From that path "libs/android-support-v4.jar" I suspect it may be problem with the structure one of your libraries. I would try making a test app that includes the libraries you are using and see if it errors. Then by a process of elimination of each library see if you can eventually get it to build.

That's a good suggestion and I will certainly try that, thanks!
But I still am struggling with the fact that my app will compile just fine, but building the app bundle fails...
Tomorrow I'll continue, today has been a lost day ?.
But thanks again!

bigbadfred · Oct 23, 2022

Hi, agraham!
I did what you suggested and limited the error to the library (wrapper) Valuebar by DonManfred.
I have no clue how to change wrappers, but maybe @DonManfred has an idea?

Erel · Oct 24, 2022

android-support-v4.jar should never be used. It is part of the old Android Support library which was replaced by AndroidX. If you have a library that depends on it then you need to remove that library.

bigbadfred · Oct 24, 2022

Thanks Erel, I guess I'll have to find myself a nice alternative for valuebar.
Too bad, I liked it a lot and used it extensively in my app.
Thanks again!
