Fatto!
il mio livello di b4a, non mi permette di "tradurre" da android studio
Quindi stai chiedendo un corso di formazione per sviluppatori di B4A?

Mi spiace il termine delle iscrizioni era 1° aprile 2019. Prova al prossimo semestre :p:p

Mah, io ho già seguito un corso di b4a base.. che mi ha permesso di creare questa app:

https://play.google.com/store/apps/details?id=eu.beraldogiuliano.worldcapitls

Ho provato anche a fare un corso di android studio, ma non ci ho capito molto..

Magri se qualcuno conosce bene entrambi i linguaggi, e magari ha già fatto applicazioni simili (a livello di codice), può indicarmi come fare

Non lo faccio a livello professionale. Son più interessato a capire come fare, che chiedere che venga fatto per me..

Ottimo mi sei già simpatico.

Cosa fa quest'applicazione? Cosa vorresti ottenere? L'app Android Studio come si collega con PHP ?
Così ti possiamo dare indicazioni. Butta giù l'interfaccia così c'è una base da cui partire.

questa applicazione è per condividere wallpapers ma la stessa dinamica può esser utilizzata anche per altri scopi.
Si collega al backend tramite okhttpPost e JSON parser
crea un db locale .db ma dove vengono caricati i dati è quello online (SQLiteDatabase)
Oltre alle immagini, carica anche altre info: email, versione, nome sviluppatore.. che possono essere aggiornate direttamente dal sito.
Ho allegato il file completo. queste info le trovi nella cartella "util" "DBHELPER".
L' url del server di riferimento, è stato inserito nel file gradle.properties.
Provo a fare un' interfaccia semplice, per cominciare con pochi dati.
Se serve aggiungo anche i file php
grazie

Quindi dall'app ricevi (e forse anche invii) wallpaper.
Associato a ogni wallpaper hai diversi campi (autore, dimensioni ecc..)
Dal PHP ricevi la lista in formato JSON e il download lo fai con http.

Ho capito bene?

si, ho 4 campi, categoria, Formato, Il percorso dell' immagine, e i vari tag.

Prendo dal server anche altri dati, come le chiavi admob, le policy privacy, il logo...
a questo punto via qui direttamente:
B4X:
http://eliteandroidapp.netsons.org/php_web_services/

Va bene anche un "pezzo" alla volta. Credo che una volta capito il meccanismo ci si può sbizzarrire di fantasia..

L' applicazione di collega ad un file API in php che genera la string json relativa.
Utilizza anche un db locale, ma non capisco quali dati vengono memorizzati.
Questo dovrebbe essere, ma senza server b4j
B4X:
https://www.b4x.com/android/forum/threads/b4x-cloudkvs-synchronized-key-value-store.63536/#content

ma non so come implementarlo.

ho anche provato a creare un' interfaccia di prova integrando Xcustomview, ma ho qualche problema per le immagini che sono "string" e non "bitmap".

Il prossimo passo è "tradurre" anche letteralmente questo:

Ciao,
ho analizzato meglio il codice android.
Utilizza anche delle classi.. le ho trasportate sul progetto b4a.

Ora se volessi creare un 'array con le variabili che inizializza la classe posso scrivere così?

Dim AItemWallpaper() As ItemWallpaper = Array(AItemWallpaper)

dove ItemWallpaper è il nome della classse con questo codice all' interno:

B4X:
Public Sub Initialize (Aid As String,ACId As String,ACName As String, Aimage As String,AimageThumb As String, AtotalViews As String, AtotalRate As String, AaverageRate As String, AtotalDownloads As String, Atags As String, ATypes As String)
       
        id = Aid
        CId = ACId
        image  =Aimage
        imageThumb = AimageThumb
        totalViews = AtotalViews
        totalRate = AtotalRate
        averageRate = AaverageRate
        totalDownloads = AtotalDownloads
        tags = Atags
        Types = ATypes
   
End Sub
public Sub getId As String
    Return id
End Sub

...etc....

Ci sono poi queste definizioni che non so come tradurre su b4a:
B4X:
public static Uri uri_setwall;
public static File file;
