Android Question PROXIMITY_SCREEN_OFF_WAKE_LOCK

What do you want to use it for?

Note that it is only available on Android 5+

Hello @Erel . I need to use to lock screen when user touches it with his face trying to use the phone (my app does voip phone calls), avoiding mistaken commands. Today I did a workaround creating a full screen activity and then putting a full screen panel consuming the touches (with a 200 alpha and colors.black , with an empty panel_click event in order to consume undesired touches when the proximity value is 0...). But if any other app puts a notification or something else in a layer over this panel I still could have mistaken touches (besides in other app, but it is still a mistaken touch from user)... that's it.

Put in starter service:

Put in starter service:

B4X:

Sub Process_Globals
   Private ProximityWakeLock As JavaObject
End Sub

Sub Service_Create
   If ProximityWakeLock.IsInitialized = False Then
       Dim ctxt As JavaObject
       ProximityWakeLock = ctxt.InitializeContext.RunMethodJO("getSystemService", Array("power")) _
           .RunMethod("newWakeLock", Array(32, "proximity"))
       ProximityWakeLock.RunMethod("acquire", Null)
       'release code:
       'ProximityWakeLock.RunMethod("release", Null)
   End If
End Sub

Manifest editor:

B4X:

AddPermission(android.permission.WAKE_LOCK)

Thanks @Erel ... a question:
- If the device has no proximity sensor... will raise an error?
And... How to know if there is or not proximity sensor?

Test it with:

B4X:

If ProximityWakeLock.RunMethod("isWakeLockLevelSupported", Array(32)) Then

End If
