Hi, I test compile my program then found this error while compiling:
But this is the error when using the Dark theme (Modify Manifest file).
This is the error when using the Light theme (Default).
Also, You can see it's the same error.
And I already install Java JDK 8 and Android 10.0 (Q) SDK...
I updated to B4A v7.80 on my laptop and I deleted my Android SDK that was installed with Android Studio and I installed a new one as explained in the SDK Manager thread (using the SDK Manager from B4A).
Now B4A can't compile my old apps because it can't find the Appcompat styles.
