Android LibGDX 应用程序在本地运行但在 alpha 测试时崩溃

Question

我有一个 libGDX 应用程序，我已经在 Google Play 商店上发布了多个版本已经好几个月了。但是现在我遇到了一个我没有运气修复的问题。

当我在我的 android 设备上启动该应用程序时，该应用程序在 Eclipse 中运行良好，但是当我导出 APK 并将其上传到 Play 商店并下载 Alpha 测试版本时，它崩溃并出现此错误:

如您所见，我遇到的第一个错误是读取文件:data/scroller/uiskin.json

这是试图在我的代码中读取此文件的行:

// Loads the ui's skin to be used on this example:
    uiSkin = new Skin(Gdx.files.internal("data/scroller/uiskin.json"),
            assetManager.get("data/scroller/uiskin.atlas", TextureAtlas.class));

重要的是要注意此文件从未导致实时发布崩溃，事实上，它与我在应用程序中实现的新功能完全无关。我正在实现 GdxPay如 Gdx-Wiki并离线测试结果，一切都按预期进行。

但是，如前所述，当由于某种原因上传到 Play 商店时，当在我的代码库的完全独立的区域中加载随机 json 文件时，它会崩溃。

启动

这是通过 Eclipse 在我的设备上启动应用程序时发生的情况:应用程序使用 Tween Engine 加载启动画面，然后自动成功加载游戏画面。

这是通过作为 Alpha 测试发布的 Google Play 商店启动应用程序时发生的情况:应用程序成功加载启动画面，然后崩溃并显示上面关于无法读取json文件。

我唯一的猜测是导出的 APK 与我在使用 Eclipse 时安装的 APK 不同。我已经在 samsung 平板电脑和智能手机 上对此进行了测试，两者都产生了与上述相同的结果。

我了解 proguard config 会影响导出的 APK，我已经更改了几次配置设置，但从 Play 商店下载和运行时它仍然崩溃。

如果有人知道是什么导致应用程序在实时崩溃但在本地运行良好，那将是一个巨大的帮助。提前致谢!

长长的； Android LibGDX 应用程序在 Android 设备上启动时在本地运行良好，但是当上传到 Play Store 并从 Play Store 启动时，它会因无法在我的代码的随机区域加载随机文件而崩溃，这在我以前的任何问题上从未给我带来过问题发布。

Answer 1

正如@Polarbear0106 所说，libGDX 的组件未包含在 APK 中。对我有用的修复方法是在 proguard-project.txt 文件中添加这一行:

“-保持类 com.badlogic.** {*;}”

然后正确导出并上传到 Play 商店，实时版本不再崩溃!
