Android Question RDC Null error

[John Decowski]

Hi I'm trying to get the RDC to execute a command,

Dim cmd As DBCommand
cmd.Initialize
cmd.Name = "insert_alert"
cmd.Parameters = Array As Object(2,2,"Hello")

reqManager.Executecommand(cmd,"tag")

Keep getting Error message:

** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (sendalert) Create, isFirst = true **
** Activity (sendalert) Resume **
** Service (httputils2service) Create **
** Service (httputils2service) Start **

Why aren't you using jRDC2: https://www.b4x.com/android/forum/threads/61801/#content ?

 

[John Decowski]

i didn't know about that but shouldn't rdc work like this though?

 

[Erel]

RDC also works. However you should start with the latest version.

 

[John Decowski]

its weird some parts of my program work fine but when i try to use it again it comes up with this null error

 

[John Decowski]

also is that jrdc you just referred me to just for b4j?

 

[Erel]

No.
