Android Question To wake screen off with a service

[brelto85]

Hi,

In my app i've a service that runs in a foreground mode and that checks the voice recognition (using SpeechRecognizer library)
When the results of recognizer are fired, is called a method in a main activity with the follow code:

Sub SpeechRecognition_Results (Words As List)
        StopService("")
        If IsPaused(MainActivity) Then
            StartActivity(MainActivity)
        Else
              CallSubDelayed(MainActivity, "StartVRAction")
        End If      
End Sub

The question is that if the screen is off and the app runs only with service running (MainActivity is hide with home button) the screen turn on correctly

If the MainActivity is active, the screen do not turn on after voice recognition result (CallSubDelayed)

Some idea to do this?

The MainActivity can only be active if the screen is on. Otherwise it is paused.

You should use PhoneWakeState to turn on the screen.

"The PhoneWakeState object allows you to prevent the device from turning off the screen."

I would turn on the screen when it turned off

Sub SpeechRecognition_Results (Words As List)
        StopService("")
        If IsPaused(MainActivity) Then
            StartActivity(MainActivity)
        Else
              '???????????????
              CallSubDelayed(MainActivity, "StartVRAction")
        End If     
End Sub
