Weird bug when running C++ code on Android devices

    Problem Description

    Hi Sonar Systems,
    I recently ported one of my cocos2d-x C++ code from Xcode to android using the build_native.py command.
    The problem is, the game behaves in a weird way – the sprites keep changing their Z positions when i tap on the screen.
    This happens on every Android device i tried (phone, tablet, jelly bean, lollipop, 720p, 1080p).
    I have sent you a video that shows this weird behavior.. please check it out and let me know if you can help me out with this.
    Thanks

    How has the design resolution been set?

    Hi,
    Thank you for your reply.
    I managed to solve this issue..
    The problem was that when i ported the app to android, the z positions were being messed up when i ran the build on android devices.
    So i simply gave z positions to all sprites and menus manually, so here’s a before and after sample code (might help someone else also)

    BEFORE: (This will draw the scene correctly, but might cause z index problems.. images start overlapping each other)
    this->addChild(sprite_sky);
    this->addChild(sprite_grass);
    this->addChild(sprite_house);

    AFTER: (Works perfect without any issues)
    this->addChild(sprite_sky, 1);
    this->addChild(sprite_grass, 2);
    this->addChild(sprite_house, 3);
