Android Question Using version-based theme with Appcompat

[Ederson Kerber]

Good Morning,

I'm using the theme in a version posted at: https://www.b4x.com/android/forum/threads/theme-based-on-version-tutorial.27624/ by @barx in an example provided by @Erel
However, I'm encountering difficulties when I use the version-based theme with an extension: android.support.v7.app.AppCompatActivity.

Here is the error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{barxdroid.VersionThemeDemo/barxdroid.VersionThemeDemo.main}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

P.S: When taking the attribute "Extends: android.support.v7.app.AppCompatActivity" the error does not happen, however, I must use the same in my application.

I need to use android.support.v7.app.AppCompatActivity due to Android version compatibility.

Thanks, I appreciate that you can help.

See AppCompat tutorial: https://www.b4x.com/android/forum/t...compatible-with-older-android-versions.48423/

You must use one of the AppCompat themes (or a custom theme that extends an AppCompat theme).
