Android Question Lock Phone On Incoming Call

[sktanmoy]

Fact: When I get a call and phone remains in my pocket, sometimes (basically when I walk), call is automatically picked up. Actually screen is too sensitive and jeans are tight enough to touch while walking

I need: I want to lock the screen when phone will remain in pocket (can detect using proximity sensor) and have a call (can detect using phone event listener)

What I did: I created an app which is perfectly detecting proximity, incoming call and lock screen using device administrator library.

What's happening: Locking is always working except when using in incoming call listener.

Any idea if (and how) I can accomplish my task in this situation.

Try to call StartActivity with a small delay to show your activity in front of the standard phone activity.

@Erel, can you please help me a bit more, how can I call an activity in front of the standard phone activity?

 

[Erel]

How are you intercepting the incoming call? With PhoneEvents?

Yes, PhoneEvents.

Make sure to call Service.StartForeground. When there is an incoming call you should show an activity with StartActivity. Use a timer to add a short delay.

#Region  Service Attributes
    #StartAtBoot: True
#End Region

Sub Process_Globals
    Dim PE As PhoneEvents
End Sub
Sub Service_Create
    PE.Initialize("Watch")
End Sub

Sub Service_Start (StartingIntent As Intent)

End Sub

Sub Service_Destroy
    PE.StopListening
End Sub

Sub Watch_PhoneStateChanged (State As String, IncomingNumber As String, Intent As Intent)
    Sleep(1000)
    ToastMessageShow(IncomingNumber, False)
    StartActivity(Main)
End Sub

Sub Sleep(ms As Long)
Dim now As Long
   If ms > 1000 Then ms =1000   'avoid application not responding error
   now=DateTime.now
   Do Until (DateTime.now>now+ms)
     DoEvents
   Loop
End Sub

Here is my service class. Cannot understand how to use Service.StartForeground here.

Service.StartForeground is not directly related to this task. You need to call it in Service_Create.

I highly recommend you to remove this Sleep method and instead use a timer.
