I am trying to implement a native module which provides connection service in react native. But I am facing an error. As I am not an android/java developer, I am not being able to find the cause of the following error.

compileSdkVersion is the SDK level which will be used to compile your
app. If you need to access properties or methods added on API 27 you
need to update this value accordingly. This means that if you needed to access (for example) Build.VERSION_CODES.P you should have set compileSdkVersion = 28 and so on...
