Segmentation Fault in libgnustl_shared.so in Android

Question

I'm running an executable in Android. The exe uses a number of shared libraries which are written in both C and C++.

I need some help on how to start debugging the following error:

interfaces[3274]: segfault at f22bacfc ip sp error 7 in libgnustl_shared.so[f4266000+ed000]

interfaces: is the binary exectutable Any tool I can used to debug this? Please share the steps.

Answer 1

You can use gdb to debug the android executable.

From this page:

1. First you need to run gdbserver on the device:
   $ gdbserver :5039 /system/bin/executable

2. The :5039 tells gdbserver to listen on port 5039 on the localhost, which adb bridges from the host to the device. executable represents the command to debug, a common one being runtime -s which starts the entire system all running in a single process. Launch gdb on the desktop. This can be done easily with the following command in the shell from which you built:
   $ gdbclient executable
