Android GDB is not loading c++ shared library

问题

I've been trying to debug a shared library that I wrote in c/c++ but I can not debug it using eclipse. When I set a breakpoint is never hit and after execute info sharedlibrary in gdb, I got he following, confirming that the library is not there (called libtest-java.so)

There is any way to load this library manually or something?? in the make file I use the following:

include $(CLEAR_VARS)

###### 
LOCAL_CPPFLAGS += -D DEBUG=1 -D NDK_DEBUG=1 
LOCAL_CFLAGS += -D DEBUG=1 -D NDK_DEBUG=1 
APP_OPTIM := debug
APP_CFLAG := -g -ggdb -O0
######

Thanks a lot for your time!

回答1:

I managed to fix it!

I was loading the library in an other class and my MainActivity was calling it when the button was pressed, therefore when GDB was ready no libraries where loaded... I thought that GDB will pick up the new library during runtime, so in order to load the library I just added the following lines in the static constructor of the first called class:

static {
        System.loadLibrary("test-java");
    }
