Can't build the library in android for buildToolsVersion = "28.0.3"

Hi and thanks for this great library
I want to build my RN app with the latest android API level (which is 28 right now) but when I try to build and run the project on my test device it fails because of this library is usig API level 23.0.1 and consequently there would be API level mismatch.
Is there any way to use this library with API levels higher than 23.0.1 at all?

My development environment info::
react-native-cli: 2.0.1
react-native: 0.59.5
JDK 1.8.0_151

Start with the Android build configuration and InCallManagerModule.java in android/src/main/java/com/zxcpoiu/incallmanager, focusing on the ActivityCompat and ContextCompat imports and the reported API 23.0.1 versus 28.0.3 setup. Reproduce the build with React Native 0.59.5 and buildToolsVersion 28.0.3; done means the library builds without the reported missing-symbol errors.
