How to create a global filter/ignore for specific null dereference warnings?

When an Android project is changed to use `compileSdkVersion 28` and `targetSdkVersion 28` the Infer tool will generate lots of warnings in Fragments like this:

```
object returned by `getActivity()` could be null and is dereferenced at line xxx
object returned by `getArguments()` could be null and is dereferenced at line xxx
```

Is there a way to turn off these 2 specific warnings in all files? Is there a way to do it by adding annotations to the file, or by setting some sort of global setting outside the Java files?

I have checked the following issues, but I don't know if they apply to this situation:

infer reports incorrectly, together with the way you run infer to reproduce the incorrect
report).
