B4J Question [ABM for dummies] real dummies :) startup question.

first of all thanks again for B4X and all the people who worked, helped debugged, etc.. it and the extra libraies, examples, etc...
I am now trying ABmaterial now. Trying everything that I can get my hands on...
As was suggested I started the lessons by Harris
You MUST be using ABMaterial 4.03 and B4J 5.90 (minimum).
1) Where can I get 'ABMaterial 4.03', should it be 4.03 or will the latest 4.30 also be OK?

In the Template folder, double click on the Template.b4j file to open the project in B4J.
Compile the app.
2) I open the project and it says: libraries missing. Should I place some extra libraries in the some folder?

Talk about dummies....

Best regards,

Versions above 4.03 should work... Haven't tested it on the tut...

What libs are missing? ABMaterial perhaps?

I just opened the Template with B4J 6.01.... It said ABMaterial library not found....

Then I opened the same using B4J 7.31 (which I upgraded to last week).
I adjusted my additional folder structures according to Erels suggestion for B4X compatibility.

Template project opened just fine with no issues... since ABM jar is in the additional libs folder.

Good luck - and enjoy ABM.

thank you.
Point 1: is ok then.
Point 2:
I am using 7.31, still not ok.
Template project opened just fine with no issues... since ABM jar is in the additional libs folder.
Still showing up an error. :(
And no, the ABM jar is not in the additional libs folder.

... much later ...

What I had to do was copy the ABMaterial4.30.jar file (I also copied the ABMaterial4.30.xml, but do not know if this is needed)

The library then showed up in the B4J IDE so that one can enable it.

Running it gives:


Me thinks we need a idiot proof setup :)

Any help?

I will persevere till the end.

Have a nice sun day everyone.

Best regards,

Installing a B4J library is basic B4J stuff, not basic ABM. It is the same for every library in B4X. You must copy ALL the jar and xml files from the library folder to your B4J library folder.

If you are really new to B4X in general, you may want to go through the B4X booklets first before tackling a big one as ABM: https://www.b4x.com/android/forum/threads/b4x-documentation-booklets.88985/

As for the error line, this is probably an incompatibility between ABM versions. You can comment out this line.

Hi Alain,

seem to be getting interest from the big boss :)
Thank you for the hints.
I have looked at booklets and did not see anything related to the handling of projects and there libraries, but I could be wrong and overlooked it.
But nevermind we are getting closser.
As to you hint, I copied all jar and xml from the ABMaterial4.30\Library to my D:\Development\B4X\AdditionalLibraries\B4J
The Compile seems to be OK :

So far so good.
The log life on top gives some warnings that (see above) but I do not think this should be a problem.

Waiting for debugger to connect...
Program started.
Start B4J Analyse!
When an error occurs, check the B4JAnalyse.log file in the Objects folder to see the last B4J line it was working on.

Some errors still exsist.

Looking at http://localhost:51045/template/ in my chrome browser gives me:

but this keeps on going and going...

I hope someone helps me out.

Many thanks.

If the dummies tutorials still use 4.03 (I haven't checked), then indeed you will need to replace its www\js, www\css and www\fonts folders with the ones for the version you use (e.g. the ones for 4.30).

Every version of ABM comes with a series of jar/xml files, and new versions of the javascript/css/font files. In a lot of cases they have not changed, but the .core ones will most likely have. (bug fixes can be in both the jar (java) and web files (js, css)). You can find this www in the library folder too.

Sorry I did not mention this :oops: These things seem so obvious for me after all these years I forget for a new user it may not be.

EDIT: Using the Chrome browser, pressing F5 and looking at the console log and network tab can be helpful to find such cases.

Just downloaded and compiled dummies template project (zip) from 2nd post (the project).

/favicon.ico - not found.... On first compile.
After second run, project loaded as expected. My ABMaterial (Version 4.03) - from libs tab.

These things seem so obvious for me after all these years I forget for a new user it may not be
Too true... even when one tries to explain the basics to a beginner.
