here is my code

your code works for me here
you can try to add this string from the thread of erel.

#AdditionalJar: androidthings, ReferenceOnly

It works for me without AdditionalJar

 

[kalarius]

with or without this
#AdditionalJar: androidthings, ReferenceOnly

I get the same error message

 

[Erel]

Based on the error message you are still using an old version of Things library.

 

[kalarius]

my version of things is 1.01
where can I find a newer version of things

 

[Erel]

I download the thing version and now shows 1.10
I download the android-thing to new version and now it is 8.1.0 api level 27

BUT the proble still exist

this is the program
Sub Process_Globals
'These global variables will be declared once when the application starts.
'These variables can be accessed from all modules.
Dim Pm As PeripheralManager
End Sub
#AdditionalJar: androidthings, ReferenceOnly
Sub Globals
'These global variables will be redeclared each time the activity is created.
'These variables can only be accessed from this module.

End Sub

Sub Activity_Create(FirstTime As Boolean)
'Do not forget to load the layout file created with the visual designer. For example:
'Activity.LoadLayout("Layout1")

Dim a As Boolean
Pm.Initialize

End Sub

******** the program does not do anything I try to start with android-things
when execute the line
Pm.Initialize

I got the error

Problem Solved

I had forgot to add the
AddPermission(com.google.android.things.permission.USE_PERIPHERAL_IO)
AddApplicationText(<uses-library android:name="com.google.android.things"/>)

at the manifest editor

( the update to raspberry ver 8.1.0 and thing lib to ver 1.1 also needed)

thank
