Android Question [B4X] [B4XPages] - Splash Screen (animated gif mod)

Hi all,
within a [B4X] [B4XPages] App I'm running the B4XPages Splash Screen (https://www.b4x.com/android/forum/threads/b4x-b4xpages-splash-screen.120851) by @Erel.

Before start coding, I have a couple of ("briefing") questions:

1) I wish to make a mod to it in order to display an animated gif instead the static image. Which is the suggested library to integrate within the B4XPages Splash Screen?
2) There are any specific / special code changes (in order to run an animated gif as cross platform solution) that I have to do to the original B4XPages - Splash Screen?

I think that this mod can be useful for many other B4XPages developers.

Thanks in advance for your suggestions
Luca.

It is very easy to find any gif and convert it to apng. There are websites that do this. I did it that way.

Cool but the problem is that "B4XPages Splash Screen" implementation doesn't support the apng format, so I can't simply replace the x.png with the x.apng file within my "B4XPages Splash Screen" project. Right ?

Try this (I don't have B4i - read the first post of the B4XGifView library about B4i)
I cannot attach the animated gif (too big file); take it from here (copy it to the Shared Folder and then click on the comment...)
Click to expand...

Great Luca
I have B4i 6.80 so I can test it.

Within a cross platform B4XPages App where I should put the B4XGifView library ?

To the additional libraries folder. You should already have this structure, I think:

In the B4X folder

I'm using B4A 10.50 and within my B4XPages App I see this folder structure ...



So I guess that I have to put the B4XGifView library within Shared Files.
But I'm little bit confusing about this because usually I put this libs within the Additional library folder but in this case I have to put it for each platform specific path ?

Yes, but don't put the library there, it has to be in the "Additional Folder":



(mouse right-click shows that dialog, click on "Open Additional..." and place B4XGifView.b4xlib and its additional files needed in the B4X folder you will find).

Ok I try this.
Only a note: but in this way I have 3 copy of the library file (B4A, B4i and B4J). Or is it possible to define a single additional lib folder and point it within all the ides ?

No, B4Xlibs are "special" libraries, you will have just one copy of B4XGifView.b4xlib in the B4X folder:

\AdditionalLibs\B4X


The above folders are in the AdditionalLibs folder.

Thanks for the info.
I'm I little bit confused (about B4Xlib Libs right path).
Before read your last reply, I did a test and I create a single folder (for all ides) for AdditionalLibs and I point all the configuration paths (B4A, B4i and B4J) to that folder (...\B4X\ADD_LIBRARIES).

Opening your project within B4A it works with no errors (see on the left of the image). B4A has loaded the B4XGifView.b4xlib without \AdditionalLibs\B4X folder.
Opening the project within B4i it doesn't work (see errors and lib missing on the right).



Note
Both AdditionalLibs folder path within B4A and B4i is set to "...\B4X\ADD_LIBRARIES".

Note2
But "No, B4Xlibs are "special" libraries, you will have just one copy of B4XGifView.b4xlib in the B4X folder" if this is true, why B4A is loading the B4XGifView.b4xlib ?

In italiano? Sorry.

Quando crei un progetto B4XPages vengono create 4 cartelle, una per ogni piattaforma (B4A, B4J, B4i), che contengono i file del tuo progetto (NomeProgetto.b4a nella cartella B4A, NomeProgetto.b4j nella B4J, ...) e SharedFiles, nella quale dovrai mettere tutti i file utilizzati dai progetti (*), come i file immagine, suoni, etc..

Le cartelle delle librerie non hanno niente a che fare con quelle 4 cartelle! Queste sono principalmente 2:
a - la cartella delle librerie interne (che si chiama Libraries), che si trova nella cartella di installazione della piattaforma, cioè dove hai installato B4A, dove hai installato B4J...
b - la cartella delle librerie aggiuntive, che puoi creare dove vuoi (basta che poi metti il path come hai fatto) e sono 4:
B4A
B4J
B4i
B4X

Le varie librerie che non vengono fornite con l'installazione, quindi le librerie aggiuntive, le metterai in queste cartelle; quelle con estensione .b4xlib nella cartella B4X, quelle con estensione .jar nella cartella della specifica piattaforma.

-------------------------

(*) Dopo che avrai messo i file nella cartella SharedFiles, nella B4XMainPage dovrai fare CTRL+Click su questo commento:

in modo che i file vengano copiati/sincronizzati dalla SharedFiles alla cartella Files del progetto sul quale stai lavorando.

"English".

When you create a B4XPages project, 4 folders are created, one for each platform (B4A, B4J, B4i), which contain the files of your project (ProjectName.b4a in the B4A folder, ProjectName.b4j in the B4J folder, ...) and SharedFiles, in which you will have to place all the files used by the projects (*), such as image files, sounds, etc...

The library folders have nothing to do with those 4 folders! These are mainly 2:
a - the internal libraries folder (which name is Libraries), which is located in the platform installation folder, i.e. where you installed B4A, where you installed B4J...
b - the additional libraries folder, which you can create wherever you want (just write the path as you did) and are 4:
B4A
B4J
B4i
B4X

You must put the libraries that are not supplied with the installation, so the additional libraries, in these folders; those with .b4xlib extension in the B4X folder, those with .jar extension in the specific platform folder.

--------------------------

(*) After you put the files in the SharedFiles folder, in the B4XMainPage you will need to CTRL + Click on this comment:

so that the files are copied / synchronized from the SharedFiles to the Files folder of the project you are working on.

Ciao Luca (ok in italiano) solo per questa risposta
Rispondo ai tuoi commenti:

1) "Quando crei un progetto B4XPages vengono create 4 cartelle..." --> si questo lo sapevo e mi era chiaro.

2) "a - la cartella delle librerie interne... b - la cartella delle librerie aggiuntive..." --> anche questo lo sapevo e mi è chiaro

3) Quello che non mi era molto chiaro è il perchè (in un progetto multi-piattaforma) devi per forza creare la cartella additional libraries duplicata per ogni piattaforma quando puoi (potenzialmente) e solo per i progetti di tipo B4X / B4XPages creare un unico folder "additional libraries" e mettere tutte le librerie dentro quel folder e far puntare gli IDE a quel folder.

4) "quelle con estensione .b4xlib nella cartella B4X" --> Ora penso di aver capito anche questa cosa. Ovvero, la cartella B4X in realtà non è nella struttura di folder del progetto ma è contenuta in una struttura a parte tipo ...\AdditionalLibraries\B4X (dove ci saranno anche le altre add libs specifiche per ogni piattaforma: B4A, B4i e B4j). Corretto ?

Non devi creare alcuna cartella "additional libraries" per un progetto. Questa cartella, che contiene le altre 4, è unica per tutte le piattaforme e per tutti i progetti che crei.
Ripeto, tu non devi creare alcuna cartella.

Esatto ma tu le hai già, sono quelle "puntate" dai path impostati negli IDE.


Remember that there is also the italian forum, where we can understand each other better
