Android NDK | How to debugging app startup or suspend app until debugger connected

Question

During investigation crash of my cocos2d-x app I faced with problem that debugger not stops in AppDelegate.cpp class at all.

My assumption is: debugger could not connect before time when this code has been executed.

Is my assumption correct? Is any workaround there?

I agree with fadden you can add call sleep (or usleep) function. In case cocos2d-x you should put it in beginning of void Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeInit(JNIEnv* env, jobject thiz, jint w, jint h) function

void Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeInit(JNIEnv* env, 
                                                       jobject thiz, 
                                                       jint w, 
                                                       jint h)
{
#if COCOS2D_DEBUG    
    sleep(30);
#endif
    ...
}

Also you should not forget to include <unistd.h> in case usleep
