问题
I have an Android application implemented with help of cocos2d-x engine. I linked protobuf library to the project and trying to SerializeToStrint() one proto-object:
ProtoMessage message;
message.set_app_id(1111);
message.set_hardware_id("test string");
std::string str;
message.SerializeToString(&str);
That's builds fine, but when I trying to start application logcat send me next log:

Please can anybody explain me causes of this?
UPDATE But if I initialize string in such way:
ProtoMessage message;
message.set_app_id(1111);
message.set_hardware_id("test string");
std::string str;
str = "test";
message.SerializeToString(&str);
everything is fine and proto serializes normally
UPDATED I added a add2line result below
new stack trace:

#07 pc 001013b4 /data/data/com.example/lib/libpromowall.so ---- google::protobuf::DescriptorBuilder::NewPlaceholderFile(std::string const&)
UPDATE and the most annoying problem I can't parse proto-object without string fields initialization.
//str - serializing protobuf object
RegistrationRequest request;
request.ParseFromString(str);
Error! When I compile that in test application on my desctop machine everything is fine. But If I compile via cocos2d-x script (ndk.r7) application crashes on mobile device
回答1:
Make sure libprotobuf.so and libpromowall.so are built with the same STL implementation: either stlport_shared or gnustl_shared.
