Use GDB in Android to debug the program in emulator

In the emulator of the Android system, there are two methods for GDB debugging: GDB debugging and gdbserver debugging.

1. Use GDB server for debugging:

A. Download the gdb server for Android from the following link

Http://www.billrocks.org/android_libs/bin/

B. Install the downloaded GDB server to your emulator.

1) Start emulator

2) download the gdb server to your emulator

Open a terminal and run:

$ ADB Shell
# CD Data
# Mkdir Bin
Run in another terminal:
$ ADB push gdbserver/data/bin

In this way, the gdbserver is downloaded to the emulator through the android ADB.

C. Run gdbserver:

#/Data/bin/gdbserver 10.0.2.2: 1234 [ARGs...]

 

D. Return to another terminal and map the Port:

$ Telnet local host 5554

Telnet to emulator and run the following command:

Redir add TCP: 1234: 1234

 

E. Run GDB on the third terminal:

$ GDB Test

Test is the program you want to debug, and then run it on the gdb command line:

(GDB) target remote localhost: 1234

Then you can debug the program as you did with GDB.

 

2. Use local GDB for debugging.

A. Download the android debugging package from the following link. It is a binary file compiled using the android toolchain:

Http://ortegaalfredo.googlepages.com/android-debug.tbz

 

B. decompress the debugging package and download GDB to your emulator. If you have a real mobile phone, you can debug it as follows:

$ ADB push GDB/data/bin

 

C. Use ADB to connect to emulator

$ ADB Shell

When running GDB, the following information is displayed:

#/Data/bin/GDB

Dlopen failed on 'libthread _ dB. so.1 '-libthread_db.so.1: cannot open shared object file: no such file or directory
GDB will not be able to debug pthreads.

This GDB was configured as "-- Host = arm-None-Linux-gnueabi -- target = ".

D. Then you can debug the program as you did with GDB.
