Try this:

1. Update your "android.jar" Path​

The most likely culprit is that your B4A is still pointing to an older version of the Android platforms (like 33 or 34).

1. Open B4A.
2. Go to Tools > Configure Paths.
3. Look at the android.jar path. It probably looks something like: C:\Android\platforms\android-34\android.jar
4. Change it to point to android-35 (or the highest version you have downloaded): C:\Android\platforms\android-35\android.jar

2. Check the SDK Manager​

If you don't see an android-35 folder in your SDK path:

1. Open the B4A SDK Manager.
2. Ensure that Platforms;android-35 is installed.
3. Also, ensure Build-Tools (version 35.0.0 or higher) is installed.

3. Update the Manifest (If needed)​

If you are specifically trying to target the latest Android features on your S25 Ultra, ensure your Manifest contains the correct targetSdkVersion.

1. Go to the Manifest Editor.
2. Ensure your target SDK is set to 35: android:targetSdkVersion="35"
