Android Question JavaObject not works in Android 14

[Sinan Tuzcu]

Hi,

Hello,

My app works perfectly on Android version 9 and older. However, starting from version 14, an issue occurs that causes the app to crash.

I would appreciate support in solving this problem.

Dim socket As JavaObject = r.GetField("socket")
Dim jo As JavaObject = Me
 jo.RunMethod("setKeepaliveSocketOptions", Array(socket, 1000, 1000, 3))

I didn’t have any problems with this on Android 9.

Should it not be:

Dim jo As JavaObject
jo.initializeContext
jo.RunMethod(......)

I suggest you share the error message that you get.
Can it be changes in protocol?

Network v1.50 - Adds support for SSL sockets

This update adds support for SSL sockets (client sockets). Example: Sub Process_Globals Private so As Socket Private astream As AsyncStreams End Sub Sub Globals End Sub Sub Activity_Create(FirstTime As Boolean) so.InitializeSSL("so", Null, "") so.Connect("bing.com", 443, 0) End...

"Is there a way to modify this code so that it also runs on Android 14?"

Dim r As Reflector
    r.Target = Socket1
    Dim socket As JavaObject = r.GetField("socket")
    Dim jo As JavaObject = Me
    jo.RunMethod("setKeepaliveSocketOptions", Array(socket, 1000, 1000, 3))

First step is to post the full error message.

This was a private API and it is no longer accessible. Which problem are you trying to solve?

 

[Sinan Tuzcu]

This

Dim r As Reflector
    r.Target = Socket1
    Dim socket As JavaObject = r.GetField("socket")
    Dim jo As JavaObject = Me
    jo.RunMethod("setKeepaliveSocketOptions", Array(socket, 1000, 1000, 3))

And this one:

Service.StartForeground(1,Notification1)

and this one

StartService(Winsock)
