我使用Intellij。一切都工作正常，和APK部署在我的Android，但它只是保持黑屏，回到家里说，“'游戏'停止：

这是我的.json文件;

    default: {
        label: { font: default-font, fontColor: white },
        background: default-pane, wrapWidth: 150
    }
},
}

这些行是奇怪的，因为如果我去掉它们，程序就能正常工作，除了按钮，显然没有出现;

skin = new Skin(Gdx.files.internal("jsonSkin.json"));
TextButton btnStart = new TextButton("Start!!", skin);
btnStart.setPosition(50f,400f);
btnStart.setSize(260f,60f);
mainMenu.addActor(btnStart);
JSON

把这个放在你的配置里：

-keep class com.badlogic.**{
   **[] $VALUES;
    *;
}

它将解决这个问题，以及反射的问题。

编辑：

以上是禁用特定软件包上所有ProGuard’s优点的顶级规则。不缩水，不混淆视听;不是为了班级，不是为了成员。
Proguard混淆了我们在皮肤文件中使用的类，Skin通过反射加载类，所以我们必须不允许Proguard更改这些类的名称。
1.包中的双星号表示该顶级包下的每个包下的每个类;
1.大括号中的星号适用于该类中的每个成员（变量、方法和常量）。

问题是json序列化器需要确切的字段名称来完成其工作。
Abhishek是正确的，但我只需要忽略scene 2d包的收缩，所以我把它放在proguard-rules.pro文件中

-keep class com.badlogic.gdx.scenes.scene2d.ui.**{
    **[] $VALUES;
     *;
 }

它将优化除皮肤加载器及其组件之外的所有其他代码。
如果你用自己的类做json de/序列化，你也需要放一些类似的东西。

-keep class com.your.game.data.**{
    **[] $VALUES;
     *;
 }

把这个写进你的proguard规则里

  • 保留类com.badlogic.gdx.graphics.g2d.BitmapFont

在我的build.gradle案例中，我为发布版本配置了以下配置：

buildTypes {
    release {
      minifyEnabled true
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      debuggable true
    }

但是我的proguard-rules.pro文件丢失了-现在默认为proguard-project.txt。所以我把config改成了这个：

buildTypes {
    release {
      minifyEnabled true
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
      debuggable true
    }

然后应用适当的proguard规则在前面的答案。
