SetApplicationAttribute(android:theme, "@style/Custom")
CreateResource(values-v20, theme.xml,
<resources>
  <style
  name="Custom" parent="@android:style/Theme.Holo.Light.Panel">
     <item name="android:windowTranslucentNavigation">false</item>
     <item name="android:windowTranslucentStatus">true</item>
  </style>
</resources>
)

CreateResource(values-v19, theme.xml,
<resources>
  <style
  name="Custom" parent="@android:style/Theme.Holo.Light.Panel">

</resources>

Hi, I manage to put above code into manifest editor and it works for small device, the status bar show on top of the image. But when I run the same program into bigger device "Samsung Note 8", the screen doesn't cover into full. May I know what did I miss out.

You are using the holo theme which is an old theme. You should use material theme on v21+.

  </style>
</resources>

With this code, I manage to show the screen in full and the status bar cover on top of the image. May I know how can I make the status bar fully transparent and just show the status bar icon only.

I downloaded the sample project from the link given. I manage to run it on in my phone, but when I try on other device, the program get crash without giving any error message. Is there any restriction ?

    If ph.SdkVersion >= 4.4 Then
        Dim jo As JavaObject
        Dim window As JavaObject = jo.InitializeContext.RunMethod("getWindow", Null)
        window.RunMethod("addFlags", Array(Bit.Or(0x00000200, 0x08000000)))
        Activity.Height = Activity.Height + 25dip
        
        If ph.SdkVersion > 20 Then
            Dim jo As JavaObject
            jo.InitializeContext
            Dim window As JavaObject = jo.RunMethodJO("getWindow", Null)
            Dim view As JavaObject = window.RunMethodJO("getDecorView",Null)
        
            view.RunMethod("setSystemUiVisibility",Array(Bit.Or(0x00002000,view.RunMethod("getSystemUiVisibility",Null)))) 'Light style with black icons and text
        End If
    End If

I did not put anything in the manifest and just put the above code, it can achieve the thing that I want. May I know is the code working fine?

Your code is very similar to the example code. You should first find out why it crashes. There must be an error message in the logs.

        Activity.Height = Activity.Height + 25dip
        
        If ph.SdkVersion > 20 Then
            Dim jo As JavaObject
            jo.InitializeContext
            Dim window As JavaObject = jo.RunMethodJO("getWindow", Null)
            Dim view As JavaObject = window.RunMethodJO("getDecorView",Null)
        
            view.RunMethod("setSystemUiVisibility",Array(Bit.Or(0x00002000,view.RunMethod("getSystemUiVisibility",Null)))) 'Light style with black icons and text
        End If
    End If

after I remove the theme in the manifest and just using the above code, everything is working.
