APOLOGIES I FIXED THIS!!


Hi. I havnt used b4a for sometime so i updated the SDK and resources and am using javac 19.0.02

On compiling to my Samsung s25 Ultra i get this error:

"Linking resources Error
res\values-v20\theme.xml:6: error: style attribute 'android:attr/windowOptOutEdgeToEdgeEnforcement' not found.
error: failed linking references."

How do I fix this please

Click to expand...

1. Update your "android.jar" Path​

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​

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)​

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