PSA: Exceptions in Future are hidden

[Nutomic]

    Future {
      throw new Exception
    }

This code does nothing at all, the app doesn't force close, and the error isn't even logged. As a workaround, you can do this:

    Future {
      throw new Exception
    }.onFailure { case e =>
      Log.w(Tag, "Error in future", e)
    }

I don't know if this can by fixed by the gradle plugin, but if not, you should probably use the workaround in your code.

I think you can use a custom ExecutionContext with an overridden reportFailure method, like so: https://github.com/macroid/macroid/blob/master/macroid-core/src/main/scala/macroid/UiThreading.scala#L9

@stanch According to doc: Failed tasks should call reportFailure to let the ExecutionContext log the problem or whatever is appropriate for the implementation.

And as I've tested with the code below, method reportFailure was not called.

Future(throw new Exception("Test"))(customExecutionContext)

Here's another workaround.

Future(throw new Exception("Test")) onFailure {
  case exc: Exception => exc.printStackTrace()
}
