Because they are using different android versions. Newer android versions I think from android 5.1 do not show icon by default. You have to do it manually.

But less than android 5 like 4.2.2 being used by the HTC can show icon.

Mcqueccu, thanks! Tell me how to do this?

Anrdoid 5+ = material theme. The icon isn't supposed to appear in the material theme.

Add to B4XPage_Created of B4XMainPage:

#if B4A
    Dim p As Phone
    If p.SdkVersion >= 21 Then
        Dim ActionBar As JavaObject = B4XPages.GetManager.ActionBar
        ActionBar.RunMethod("setDisplayUseLogoEnabled", Array(True))
        ActionBar.RunMethod("setDisplayShowHomeEnabled", Array(True))
        Dim bd As BitmapDrawable
        bd.Initialize(xui.LoadBitmapResize(File.DirAssets, "logo.png", 32dip, 32dip, True))
        ActionBar.RunMethod("setLogo", Array(bd))
    End If
    #End If

Erel, thanks!
And how to make sure that there is an icon on the B4XMainPage, but not on other pages?

 

[Erel]

All the pages are hosted in the same activity. You will need to change this:

ActionBar.RunMethod("setDisplayShowHomeEnabled", Array(True))

To false when other pages appear.

To false when other pages appear.

Tell me how you can track these events?
