node_modules/react-native-serial-port-api/android/src/main/java/com/bastengao/serialport/EventSender.java:3: error: package android.support.annotation does not exist
import android.support.annotation.Nullable;

I have this issue when I debug.

All you need to do is to replace 'import android.support.annotation.Nullable' in class imports to
import androidx.annotation.Nullable;
