Signal 11 (SIGSEGV), fault addr in android when using Bump API

Question

I am trying to develop an application in which I use bump API. Everything works fine for the first time. Somehow if I press home button and came back to the application it gets crashed without any exception (sometimes it works fine for 2 or 3 times). When I checked the logcat I got following stack trace:

The bump API is included as a native library into my application (libandroid-api.so). In order to connect to the bump server I’m using a service and during the onStop (when I press home button) I am unBinding the service and during onStart (when resuming it from background) I will be Binding the service. So if I continue this UnBinding and Binding for 2 or 3 times I am getting this error.

I have done some searching about this signal 11 (SIGSEGV), fault addr, and found out it is happening when application makes an invalid memory reference. I didn’t have any access to this native library. I don’t know what to do.

Answer 1

I had the same problem, the fact is the first api.configure is working fine, the next attempt just crash the application.

I posted what I believe the same problem here: Bump API Android crash

I resolved it myself, I built a singleton around the bump api, so I ensure that the api is configured just one time and then it is only returned once already configured. You'll find the code in my question.

Answer 2

You should only call configure once per app run on the singleton.
