How to set up debugging of an android program?

Question

Android

Good day everyone, I recently started to understand the development for android and I want to understand how to debug programs on the phone. I can build a program, even a simple one, written in c/c++ and upload it to my phone. I can do it, but I haven’t figured out how to debug it yet, I read a lot of information and got confused. Can anyone explain or suggest a good guide? I have a rooted Nexus 5 (android 6). How do I connect a debugger to my application, as I understand it, you can configure gdbserver or somehow load it using ndk-gdb .. but there are a lot of guides on debugging libraries for apk, not full-fledged executable files

Answer 1

in fact, there are usually enough logs .... if not, android studio has load monitoring tools, etc.
I know that there is a debugger, but I have never needed it yet

Answer 2

This instruction helped me at one time:

I think it can really be transferred to AndroidStudio
And by the way, native code always seems to come as a library on android. And a wrapper of Java calls is made around it.
