Android Question Different button sizes in Msgbox2Async and Android 11

[Creideiki]

Hi,

on devices with Android 11 my Msgboxes create sometimes very small buttons. Both boxes are created with Msgbox2Async, the one with the small buttons directly in Main.Activity_Create, the one with the normal buttons a bit later in a sub which is called from Activity_Create.
There are other boxes in other activities, which sometimes show tiny and sometimes normal buttons.

Does anyone have an idea what happens there?

It looks like you are using Android 2 theme. This is a big mistake.

Delete any theme related code from the manifest editor and add:

CreateResourceFromFile(Macro, Themes.LightTheme)

 

[Creideiki]

Oh, well... that crashes my UI quite much, especially the colors...
Is there no way to get the old Theme.Light outfit?

I had a simple

SetApplicationAttribute(android:theme, "@android:style/Theme.Light")

BTW: I have a transparent Activity to show Boxes from e.g. Services, It uses

SetActivityAttribute(TransparentActivity, android:theme, "@android:style/Theme.Translucent")

I assume I have to change something here, too?
Is there a tutorial anywhere out there?

It will not work on Android 10+ unless you handle the special "draw over apps" permission.

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

Using an Android 2 theme on new devices is likely to cause all kinds of problems.

Sorry for the delay.

The TransparentActivity works - but it shows the old theme.
How can I use the standard theme for that?

 

[Erel]

I'm not sure that there is a material transparent theme. Better solution is to replace the transparent activity with a simple class and show it inside the current page or activity.
Maybe use B4XDialog with a custom dialog.

Thanks for the answer... I'm using the transparent activity for Services to show information for the user. So a replacement is not that easy... I was happy when I managed to do that with a transparent activity ;-)
Would a B4XDialog work better than a MsgboxAsync?

It will allow you to customize it.

 

[Creideiki]

Well, it seems to work (with Android 11, too). I in fact have to customize a bit, but this way I can do some things which weren't possible before.
