Android Question setSpeakerphoneOn- Android 9

[Jmu5667]

Hi

Has anyone got this working ? I have tried all existing methods, but none seem to work on 9.

This is the code being executed in an Activity

Dim rr As Reflector
rr.Target = rr.GetContext
rr.Target = rr.RunMethod2("getSystemService", "audio", "java.lang.String")
rr.RunMethod2("setSpeakerphoneOn", True, "java.lang.boolean")

Unfiltered logs reports an error

Have you tried to run that code in another thread?

I don't know, but a wildly uniformed throw-of-the-dart is: could it have something to do with permissions, alongside the PlayStore clampdown on accessing the Phone services?

This line from the log hints in that direction:

com.is.vitllinkSOSdo not have using speaker authority in call

Works fine here:

Sub Activity_Create(FirstTime As Boolean)
   Dim rr As Reflector
   rr.Target = rr.GetContext
   rr.Target = rr.RunMethod2("getSystemService", "audio", "java.lang.String")
   rr.RunMethod2("setSpeakerphoneOn", True, "java.lang.boolean")
End Sub

Tested on Android 9 device.

Thanks for all the help on this one, is it possible that specific Devices can outright refuse MODIFY_PHONE_STATE permission ?

any B4A code for this ?

Taking a closer look at that hint, it looks like the app needs to be the default Phone app for this to work. Would that be true in your case? If not, then this is not the proper solution. Looking at some various links, that seems to be a lot of work (setting up a default Phone app - not dialer) for this issue.

I would suggest that you look at the unfiltered logs on the device that it does not work on, see post #7. I have the same code working fine on other devices that have android 9 on them so it seem to be a device specific issue, which is beyond your control.
