Traceur enables easier debugging of RxJava2 exceptions, by appending the source of any asynchronous calls to the original exception.

An example RxJava exception:

The same exception with Traceur enabled:

Notice that the call site of the asynchronous call is linked in the stack trace (SplashPresenter).

RxJava1 had a similar feature included by default, RxJavaHooks.enableAssemblyTracking(), but RxJava2 has no such feature unfortunately.

Usage

Enable logging:

Traceur.enableLogging();

Disable logging:

Traceur.disableLogging();

Download

compile 'com.tspoon.traceur:traceur:1.0.1'

Thanks

Thanks to David Karnok - this project is largely just an enhancement of his RxJava2Extensions project, making it slightly easier to consume as a developer
