Answer 1

I tried to search to solve above issue for my app but i did not find any good answer.after struggling a lot, I was able to fix it. so solution is given below in steps.

1. Locate gdb.exe on your windows machine. Most probably it would be here:C:\Microsoft\AndroidNDK64\android-ndk-r16b\prebuilt\windows-x86_64\bin

2. Create a new file with name".gdbinit" in the directory where gdb.exe is.

3. Open.gdbinit in notepad and add 4 and 5 lines in the file:

4. set auto-load safe-path /

5. handle SIGXCPU SIG33 SIG35 SIG36 SIG37 SIG38 SIGPWR nostop noprint

6. Now create a system Environment variable with name "HOME" and set its value the directory of your.gdbinit. this is same directory where gdb.exe resides.

7. Restart Visual studio and now these signals will not be there and we can debug c++ code easily.
