Answer 1

This kind of errors usually happens when something went wrong in the native part of the API you are using (Shared Object) which is written in C or C++. Or perhaps if you are writing your own native library using NDK and there is a problem in it.

A signal is a software interrupt delivered to a process. The operating system uses signals to report exceptional situations to an executing program. Some signals report errors such as references to invalid memory addresses (SIGSEGV); others report asynchronous events, such as disconnection of a phone line.

What you had is SIGBUS which is you can find more information about it here. And you can know more about signals from here and all the types of it.
