Android Question Get exact screen size

[MitchBu]

When I use the method at
https://www.b4x.com/android/forum/t...matescreensize-vs-activitysize.50846/#content

I get 8"x 5". But my tablet is exactly 8.5" x 5.5".

Erel recommends to use the method in the post below to get the exact size, but I don't see how I can apply that.

I will appreciate help.

I am not sure, but if the home button is software (visible only with device in turn on) then this is why it show smaller.

The best is to provide us a screen shot

No, this device (Samsung Galaxy Tab A) has a hardware home button.

I am sure Erel will explain how to use what he linked to.

    Dim r As Reflector
    r.Target = r.GetContext
    r.Target = r.RunMethod("getResources")
    r.Target = r.RunMethod("getDisplayMetrics")
    Log(r.GetField("xdpi"))
    Log(r.GetField("ydpi"))
    
    Log(GetDeviceLayoutValues.Width/r.GetField("xdpi"))
    Log(GetDeviceLayoutValues.Height/r.GetField("ydpi"))

Great.

I just tried, and it is extremely precise.

Since my app is printing on a letter size sheet of paper, I will be able to present the user with Wysiwyg on the screen when a tablet offers 8 1/2 inches wide.

Thank you William
