I think there is a bug in Cocos Creator where a TiledMap is missing when built to an android device.
I have created a project in Cocos Creator. It has a scene with a Sprite and a TiledMap.
I have tested out my project on my android device, but the TiledMap does not appear on my device. Only the sprite is visible.
I have tested my project on both browser and simulator and in both cases, both the TiledMap and the sprite are present.
