由于某种原因，在我的应用程序中添加按钮后，它已停止在Android上运行。它在桌面上按预期工作，但是当尝试在Android上运行时，应用程序构建成功，启动，然后在加载场景之前立即崩溃。我试图通过aLogcat查看日志，但是我在这些日志中看不到任何信息表明发生了问题。
我得出的结论是，这个问题与添加到舞台上的uiskin /按钮有关，因为我可以添加没有任何演员的舞台，应用程序仍将在android中运行。 uiskin.json文件中列出的文件都应该位于/ android / assets目录中。我做错了什么吗？我错过了什么？
uiskin.json

最终纠正此问题的是从libgdx repository on github下载默认的uiskin文件。我从头开始构建它们时显然错过了什么？我在回购中使用的文件是：
答案 1 :(得分：0)
我认为加载uiskin文件需要很长时间。尝试代替skin = new Skin(Gdx.files.internal("uiskin.json"));之类的东西：
AssetManager manager = new AssetManager();
manager.load("uiskin.json", Skin.class);
manager.finishLoading();
skin = manager.get("uiskin.json", Skin.class);
在完成游戏之前，不要忘记丢弃AssetManager。
