Question

我有一个应用程序，当我在桌面上运行它时，资产很好，它运行正常，但是当我尝试在 Android（模拟器或设备上的 apk）上运行它时，它会强制关闭，我得到 log cat 错误：

这里是我设置资产的地方：

Texture playButtonTxture = new Texture(Gdx.files.internal("data/playButton2.png"));

我查看了许多其他类似主题的主题，并尝试了以下方法：

在资产下创建数据文件夹 刷新 eclipse 资源管理器 项目 > 清洁 刷新项目的gradles 三重检查文件路径 重新启动 IDE 从资产名称中删除大写字母（这是神话还是实际问题？）

资产在正确名称的android资产下的data文件夹中，我尝试了多种不同的解决方案组合。

注意 - 如果我要删除此资产并继续前进，我相信我会在下一个资产中遇到同样的错误。

当我尝试使用小写的断言名称并更改 android/asset/data 文件夹和游戏中的资产名称时，我得到了同样的错误：

Answer 1

当我以错误的方式实现 Google Play 服务库时，我遇到了类似的问题。 它还包含一个资产文件夹，我的 Android 项目以某种方式链接到该文件夹​​。

因此，如果您实施了 Google Play 服务，请尝试将其删除，看看是否可行。 然后以正确的方式将其添加到项目中。

希望这会有所帮助！
