DESCRIBE THE ISSUE IN DETAIL:

STEPS TO REPRODUCE:

I cannot reproduce this issue outside of our repo and here is what I know from my investigation.
project.allLibraries is a NonNull function. The code shouldn't produce null value.
To be able to debug, I copied the same rule into our project. I added two println(context.project.allLibraries) before context.getLocation(attr, LocationType.VALUE) call. They print the expected project list and more importantly, the following call to getLocation does NOT crash.

I resolved our issue by inlining the rule and calling allProject.

Exception in filterIncident causes https://issuetracker.google.com/issues/291446497.

TranslucentViewDetector should not throw an exception when context.getLocation(attr, LocationType.VALUE) is called.
I expect an exception in filterIncident to fail the lint run.

java.lang.NullPointerException: project.allLibraries must not be null

Marked as fixed, reassigned to tn...@google.com.

for example, many different devices return the same longitude and latitude.such as : longitude is 121.474000 and latitude is 31.230001.
i donnot understand why is the data the same?

the fractional part of the location data is exactly the same.
