Android 统一facebook sdk'；没有'；“找不到类”；com.facebook.facebook内容提供商“'；还有什么建议吗？

如何复制此错误

• 创建一个新的Unity项目

• 导入facebook sdk unitypackage

• 通过facebook\Edit Settings为facebook设置应用程序Id

• 使用Assets\External dependency manager\Android，按“解析依赖项”，然后按“删除解析库”（否则构建将在渐变阶段失败）

• 构建并运行

• 当应用程序尝试运行时，我立即在手机上收到错误消息“应用程序已停止工作” 在日志中看到这个错误

  Caused by: java.lang.ClassNotFoundException: Didn't find class "com.facebook.FacebookContentProvider" on path: DexPathList[[zip file "/data/app/com.SandwichGeneration.MakeASquare--nLEHpzOYlwW6XKmGzPfIw==/base.apk"],nativeLibraryDirectories=[/data/app/com.SandwichGeneration.MakeASquare--nLEHpzOYlwW6XKmGzPfIw==/lib/arm64, /data/app/com.SandwichGeneration.MakeASquare--nLEHpzOYlwW6XKmGzPfIw==/base.apk!/lib/arm64-v8a, /system/lib64, /system/vendor/lib64]]
  

我尝试过的建议修复方法

我尝试了新旧facebook SDK和新旧Unity版本的不同组合

我试着从一些不同的机器构建到不同的Android设备

我已经删除了facebook sdk中包含的外部依赖关系管理器，并使用了它。为了解决这个问题，我必须在“发布设置”下的播放器设置中设置“自定义渐变属性模板”

我在“发布设置”下的播放器设置中设置了一个自定义Proguard文件，并在该文件中添加了以下两行

-keep class com.facebook.internal.* {*;}
-keep class com.facebook.* {*;}

  -keep public class com.facebook.**{public *; } 
  -keep public class com.facebook.internal.**{ public *; }

---

因此，我尝试了所有建议的修复方法及其各种组合。我不知道我还能做什么。有人能推荐其他方法来尝试吗？

好的，这里有一个具体的方法，我是在它起作用的地方采用的

• 统一版本：2019.3.15f1

• Facebook SDK版本：7.21.2

• 使用PlayServicesResolver解析库

• 不删除已解析的库

• 在“发布设置”下的“播放机设置”中设置自定义Proguard文件，并将以下两行添加到该文件中

  -keep class com.facebook.internal.* {*;}
  -keep class com.facebook.* {*;}
  

    -keep public class com.facebook.**{public *; } 
    -keep public class com.facebook.internal.**{ public *; }
  

• 从mainTemplate.gradle中注释掉这些行

       com.android.support:appcompat-v7
       com.android.support:support-v4
       com.android.support:customtabs
  

所以你的mainTemplate.gradle看起来像这样

    `// Android Resolver Repos End
    apply plugin: 'com.android.library'

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.google.android.gms:play-services-ads-identifier:17.0.0' 
    // Android Resolver Dependencies Start
        //implementation 'com.android.support:appcompat-v7:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
        //implementation 'com.android.support:support-v4:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
