解决方法:

Java_org_cocos2dx_lib_Cocos2dxRenderer.cpp和TouchesJni.cpp里相关方法都给加上NULL的判断:

JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeOnPause() {
if (CCDirector::sharedDirector()->getOpenGLView()) {
CCApplication::sharedApplication()->applicationDidEnterBackground();

CCNotificationCenter::sharedNotificationCenter()->postNotification(EVENT_COME_TO_BACKGROUND, NULL);
}
}

JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeOnResume() {
if (CCDirector::sharedDirector()->getOpenGLView()) {
CCApplication::sharedApplication()->applicationWillEnterForeground();
}
}

JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeTouchesBegin(JNIEnv * env, jobject thiz, jint id, jfloat x, jfloat y) {
if (CCDirector::sharedDirector()->getOpenGLView()) {
cocos2d::CCDirector::sharedDirector()->getOpenGLView()->handleTouchesBegin(1, &id, &x, &y);
}
}

JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeTouchesEnd(JNIEnv * env, jobject thiz, jint id, jfloat x, jfloat y) {
if (CCDirector::sharedDirector()->getOpenGLView()) {
cocos2d::CCDirector::sharedDirector()->getOpenGLView()->handleTouchesEnd(1, &id, &x, &y);
}
}

JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeTouchesMove(JNIEnv * env, jobject thiz, jintArray ids, jfloatArray xs, jfloatArray ys) {
if (CCDirector::sharedDirector()->getOpenGLView()) {
int size = env->GetArrayLength(ids);
jint id[size];
jfloat x[size];
jfloat y[size];

env->GetIntArrayRegion(ids, 0, size, id);
env->GetFloatArrayRegion(xs, 0, size, x);
env->GetFloatArrayRegion(ys, 0, size, y);

cocos2d::CCDirector::sharedDirector()->getOpenGLView()->handleTouchesMove(size, id, x, y);
}
}

JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeTouchesCancel(JNIEnv * env, jobject thiz, jintArray ids, jfloatArray xs, jfloatArray ys) {
if (CCDirector::sharedDirector()->getOpenGLView()) {
int size = env->GetArrayLength(ids);
jint id[size];
jfloat x[size];
jfloat y[size];

env->GetIntArrayRegion(ids, 0, size, id);
env->GetFloatArrayRegion(xs, 0, size, x);
env->GetFloatArrayRegion(ys, 0, size, y);

cocos2d::CCDirector::sharedDirector()->getOpenGLView()->handleTouchesCancel(size, id, x, y);
}
}
