Crashing without internet connection #3

Closed ysoftware closed 5 years ago

ysoftware commented 5 years ago

My app crashes when there is no internet connection using your library.

I can see that the problem is somewhere in rxjava and not exactly your code but I can't seem to catch this exception.

Any suggestions?

Could you post the snippet of code where you subscribe to the observable? This is caused by not handling onError, could you let me know which method you are calling? I can verify it's not internal to the SDK.

Thanks a lot. Indeed, I forgot to add a block to handle errors. All works now.
