General / Debugging SFML android app
« on: February 06, 2016, 05:47:11 pm »
I am starting out development of a small game using SFML and TGUI. So far I just have a bare bones menu example which works fine on OS X, but when I launch it on Android it crashes and I see this in the adb logcat:
What does it mean? I searched these forums and one post says it's threading issue, but I am not using threads (at least not that I know of). The android example bundled with SFML works fine, so it must be my mistake.
I have a simple state machine which stores states in a std::vector and each state has access to sfml::RenderWindow through a single Game object like this:

Any idea what might be wrong or a better way to go about debugging than using logcat?

I have a simple state machine which stores states in a std::vector and each state has access to sfml::RenderWindow through a single Game object like this:
class Game
{
public:
sf::RenderWindow window;
std::vector<GameState*> states;
void pushState(GameState* state);
void popState();
void changeState(GameState* state);
GameState* peekState();
};
...
class GameStateStart : public GameState
{
public:
Game* game;
GameStateStart(Game* game) : game(game) {}
virtual void draw(const float dt)
{
this->game->window.draw(...);
}
};
{
public:
sf::RenderWindow window;
std::vector<GameState*> states;
void pushState(GameState* state);
void popState();
void changeState(GameState* state);
GameState* peekState();
};
...
class GameStateStart : public GameState
{
public:
Game* game;
GameStateStart(Game* game) : game(game) {}
virtual void draw(const float dt)
{
this->game->window.draw(...);
}
};
