Dear users, i am struggling to receive data back from a external webpage.
The page must return 3 strings that i want to capture in b4x.
The tablet OS is Android 16 and to my knowledge Google gas tightend the java it.
I does not have to be complicated the 3 string are less that 256 chars.
It is data from a database, id, number, description.
So my question is simple how to get databack to the b4a app that holds the webview?

Paul, Here is my method of connecting to a hosted server. It works great and gives almost instant results.
The write-up includes the call and read logic from b4a and the php logic to read the query, search the DB, and return the query.
You are not 'syncing' as I am, but the principle of reading the DB would be the same, I would think.
You only have to issue the b4a 'query' to 'read' and the php reading of the DB and returning the result.

Syncing local databases using PHP to access a database on a hosted server

My need was to sync calendars in which user 'A' changes the calendar and sends the change to other users by writing records to the hosted database. The other users query periodically to see it they have any incoming sync records and read them if available. I had hoped to use Erel's JDRC2...
