Very cool Klaus! Will be a huge help for people getting started with B4J.

You can now create a B4X beginners guide, just by merging the 4 guides into one!
That would be the coolest!

Thank you for all your contributions to this community, @klaus, you ROCK!

Great! Do you need somebody to translate it into other languages? I can translate it into Chinese in my spare time.

I had already a similar idea.
But merging the 4 guides into one would become too big.
The future will be B4X Booklets for different subjets like IDE and Designer, Basic Language, CustomViews, SQLite etc.

Collectibles! That would be a great idea!!! so in each booklet, all platforms would be targeted, highlighting the differences between them!(?)

... all platforms would be targeted, highlighting the differences between them!(?)

Yes, that's the project.

 

[mindful]

@klaus at page 9 chapter 1.1.1 Installing Java JDK the line :

Select "Windows x86" in the platforms list (for 64 bit machines as well).
You should install the regular JDK for 64-bit computers as well.

I do not think is correct as I compile and run without problems a project with the JDK for 64-bit computers.

And also on the https://www.b4x.com/b4j.html it states:

Select "Windows x86" or "Windows x64" (for 64 bit machines) in the platforms list.

Anyway very good work you have done with this! Hope many people find it easier now to start using B4J.

Best regards,

Klaus - you're like a Santa CLAUS man.

Bearing precious "gifts"

Wonderful work man - you're awesome.

How can I make a "small" donation as a token of my appreciation and gratitude?

How can I make a "small" donation...

The likes are OK for me.
There will never be a Donation button in my signature.
I do it as long as I have pleasure doing it.

Klaus - you're a wonderful person

Bless you
