I have a same issue. I found out that if there's test code located in src, it caused this kind of build failure.
This problem appears at 0.5.0-alpha.49, 0.5.0-alpha.50 version. If you downgrade to 0.5.0-alpha.48, it will be solved.

[RORrvtech]

its not true, if you use example above which used 0.5.0-alpha.50 successfully compiled. its more like a gradle setting which is not mentioned in Readme.md

Example[] https://github.com/mauron85/react-native-background-geolocation-example/blob/master/package.json

Oh, I use gradle version 3.2.1 and many other native libraries, so one of them could be a problem.

I have the same issue too for the same version of the library.
By inspecting a little bit the code what it seem to me is that junit dependency is declared for test and used instead in main. Moreover I don't understand why is necessary an Assert inside the LocationServiceIntentBuilder class but maybe is something I miss.
I hope this help.
Meanwhile I will inspect a bit more and hopefully I will provide a possible solution

@scurtoni
I agree. The test code in LocationServiceIntentBuilder.java cause the problem and LocationServiceIntentBuilder.java was added from 0.5.0-alpha.49. So, downgrading to 0.5.0-alpha.48 will solve the problem, but it will be great if test code in LocationServiceIntentBuilder.java file will be removed.

I also experienced this compilation error after updating the following settings in my project build.gradle:

  buildToolsVersion = "27.0.3" -> "28.0.2"
  compileSdkVersion = 27 -> 28
  supportLibVersion = "27.1.1" -> "28.0.0"

As mentioned above, reverting to 0.5.0-alpha.48 fixes the issue.

Apparently I made mistake using Assert from junit testing framework. Consider this as a bug. Need to be fixed. But on the other side, using Assert is perfectly fine here. You really don't want to continue when there is missing (null) Context. But it should be assert from standard library, not from junit.

Just merge @scurtoni 's PR mauron85/background-geolocation-android#25.

FYI: New version 0.5.0 with fix has been published to npm
