Android Question Problem with Android version 15 and higher

[Filippo]

Hi,

There is this warning in the Play Console:

2 actions recommended

Your app no longer uses supported APIs or parameters for borderless display
At least one of the APIs or parameters you are using and for which you have specified the use of borderless and window display has been discontinued in Android 15. Your app uses the following APIs or parameters that are no longer supported:

• androidx.core.view.WindowCompat.setDecorFitsSystemWindows
• android.view.Window.setDecorFitsSystemWindows
• androidx.core.view.WindowCompat$Api30Impl.setDecorFitsSystemWindows
• LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES
  
  They start at the following points:
• androidx.compose.ui.window.DialogWrapper.<init>
• androidx.core.view.WindowCompat$Api30Impl.setDecorFitsSystemWindows
• androidx.core.view.WindowCompat.setDecorFitsSystemWindows
• androidx.activity.EdgeToEdgeApi28.adjustLayoutInDisplayCutoutMode
  
  Migrate away from these APIs or parameters in preparation for the switch to Android 15.

Now I have to check where I need to change something.

 

[LucaMs]

I'm afraid you'll have to wait for Erel to intervene.

 

[Erel]

I don't think that B4A framework make calls to any of these APIs.

 

[MarcoRome]

Do you use something like this ?

Manifest:

SetApplicationAttribute(android:windowLayoutInDisplayCutoutMode, ...)

or code:

....
jo.RunMethod("getWindow", Null)
....

Ciao Marco,

No, I don't use this kind of code in any of my apps.

I have the same Google recommendation for almost all other apps.

Hi,

the function “setDecorFitsSystemWindows” comes from this library, but as far as I know, I don't use this library in any of my apps.

These continual breaking changes to Android are ridiculous. On Windows I can still run 25 year old plus complex applications from the Windows XP era (Office XP among them) without problems - but not so for a few year old apps on Android

 

[Filippo]

These continual breaking changes to Android are ridiculous.

Not even Apple is as bad as Google.

Hi,

I bought a new phone with Android 15 today to test the new SDK-35, here is my first test result.

The App-settings are as follows:

#Region  Activity Attributes
    #FullScreen: True
    #IncludeTitle: false
#End Region

How can I use these settings in B4x?

I have the same warnings in my apps. I m using b4xpages.

Will #FullScreen: False work?

 

[Filippo]

Hi,
How can this function be implemented in B4x?
I've been trying for a few hours, but I can't manage it.

WindowInsets.safeGestures

 

[Filippo]

Will #FullScreen: False work?

Yes, but it looks even worse to me.

 

[hung]

Yes, but it looks even worse to me.

Great. Found even android developer forum shows no simple solution but change a lot from source code level.
Well the best solution right looks like: temporally announce "Android 15 not fully supported yet". cheers

 

[Filippo]

Hi,

I have now tested with version 13.03 Beta #1, but the result is the same, no change.
I have used these Code Snippets .

 

[Mr.Coder]

Hi,

My apps work without problems in android 15 and later, I use this code to know where the correct or safe area :

Private Sub GetSystemWindowInsets(gInsetsType As String) As Int()
    
    Dim gWindowInsets(4) As Int
    
    Try

        '[Insets Types] :

        'system window insets.
        'When View#SYSTEM_UI_FLAG_LAYOUT_STABLE Is requested, an inset will be returned even when the system gestures are
        'inactive due To View#SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN Or View#SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION.
        
        '[systemOverlays]
        'System overlays represent the insets caused by the system visible elements. Unlike navigationBars() or statusBars(),
        'system overlays might not be hidden by the client. For compatibility reasons, this type is included in systemBars().

           gWindowInsets(0) = oInsets.GetField("left").As(Int)
           gWindowInsets(1) = oInsets.GetField("top").As(Int)
           gWindowInsets(2) = oInsets.GetField("right").As(Int)

        Return gWindowInsets
        
    End Try
    
End Sub

Then in Activity_Create event :

gStatusBarsInset = GetSystemWindowInsets("statusBars")
gNavigationBarsInset = GetSystemWindowInsets("navigationBars")

CorrectScreenHeight = Activity.Height - gStatusBarsInset(1) - gNavigationBarsInset(3)
CorrectScreenWidth = Activity.Width   
CorrectScreenTop = gStatusBarsInset(1)
CorrectScreenBottom = gNavigationBarsInset(3)

- I hope this is useful to you.

 

[Filippo]

- I hope this is useful to you.

Thank you very much for your help.
Unfortunately it does not work for me.
I have done the following:

    Dim gStatusBarsInset(4), gNavigationBarsInset(4) As Int
    Dim CorrectScreenHeight, CorrectScreenWidth, CorrectScreenTop, CorrectScreenBottom, CorrectScreenLeft As Int
    gStatusBarsInset = GetSystemWindowInsets("statusBars")
    gNavigationBarsInset = GetSystemWindowInsets("navigationBars")

    CorrectScreenHeight = Activity.Height - gStatusBarsInset(1) - gNavigationBarsInset(3)
    CorrectScreenWidth = Activity.Width
    CorrectScreenTop = gStatusBarsInset(1)
    CorrectScreenBottom = gNavigationBarsInset(3)
    CorrectScreenLeft = gNavigationBarsInset(0)

    Activity.LoadLayout("frmmain")
   Activity.SetLayoutAnimated(0, CorrectScreenLeft, CorrectScreenTop, CorrectScreenWidth, CorrectScreenHeight)

Then I get this error message:

I do not change the activity Layout position, but I change the views position that loaded inside the activity to make it visible. and I use this App-settings :

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: False
#End Region

try to not use SetLayoutAnimated for activity and use it for views inside activity.

After your settings is even worse.
