Error in compiling APK

[mukhlis7]

When i try to sync the project i got this error every time

WARNING: The specified Android SDK Build Tools version (28.0.2) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.4.1.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '28.0.2'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
Remove Build Tools version and sync project
Affected Modules: app

And there is another error

Schema export directory is not provided to the annotation processor so we cannot export the schema. You can either provide room.schemaLocation annotation processor argument OR set exportSchema to false.

And

/root/AdoBot/app/src/main/java/com/android/adobot/SmsBroadcastReceiver.java:

Recompile with -Xlint:deprecation for details.
