when I call cocos2d::JniHelper::getStaticMethodInfo,Fatal signal 11 (SIGSEGV) occured

cocos2d-x C++
#1

My app can run normally on android devices or emulators from eclipse except Kindle fire tablets,inclucding kindle fire emulator,kindle fire 2 emulator and kindle fire HD7 emulator.Debugging a lot,I finally found the call to cocos2d::JniHelper::getStaticMethodInfo resulted in the crash.The method code referencing cocos2d::JniHelper::getStaticMethodInfo is as follows:
@ std::string cpCallJava(const std::string &class_name, const std::string &method_name,
const std::string &param1, const std::string &param2) {
CP_LOG(“In cpCallJava function.”);

CP_LOG(“before-class_name:s method_name:s param1:s param2:s”,class_name.c_str(),method_name.c_str(),param1.c_str(),param2.c_str());
cocos2d::JniMethodInfo methodInfo;
CP_LOG(“after-class_name:s method_name:s param1:s param2:s”,class_name.c_str(),method_name.c_str(),param1.c_str(),param2.c_str());

if (! cocos2d::JniHelper::getStaticMethodInfo(methodInfo, class_name.c_str(),
method_name.c_str(), “(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;”)) {

return “”;
}@

And here is the log near the crash:

Any help would be highly appreciated;-)

I’m sorry I’ve made a mistake,cause the class_name I passed in is something like “com.xxx.xxx” and it should be “com/xxx/xxx”.
