In Android Studio invoked on c + + project, through will be compiled into c + + project. A library, through again. So library link, the AS engineering through. So to invoke the c + + project, and in the AS AVD raised, but prompt the following two problems, lead to app installed directly on the AVD stop,
Question 1:
(SIGSEGV signal SIGSEGV: invalid address (fault address: 0 xfffffff4))
Internet the following arrays allocated memory is too large will cause SIGSEGV signal, how to set up in the AS this?
Question 2:
AVD is armeabi - v7a, but always tip:
. Android \ \ the NDK \ 20.0.5594570 \ Sdk toolchains \ LLVM \ prebuilt \ Windows - x86_64 \ sysroot \ usr \ include \ \ c + + v1 \ ostream
"This file does not belong to any project target, code insight the features took the not work properly."
So generated when the virtual machine is arm, also the arm, why didn't here will prompt the Windows ostream?

Is there anyone who can help me to analyse the reasons for the above two questions? Thank you very much!
