Answer 1

尝试添加-keep class io.grpc.** {*;}到您的 proguard 配置中。它应该有效。自从我添加它以来，还没有发生过任何崩溃。将进一步测试。

Answer 2

注意我正在使用 Flutter，所以这应该适用于 Java/Kotlin Android 和 Flutter

花了几个小时后，我修复了它

1

检查路径 yourproject/Android/app 中是否存在 proguard-android.txt 或 proguard-rules.pro

2

如果它们存在，请复制下面的配置，如果不存在，请为它们创建单独的文件，包括我提到的路径中的相同名称（proguard-android.txt 和 proguard-rules.pro）

3（配置线）

   -keep class io.grpc.** {*;}
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

将上面的代码粘贴到两个文件中。

4（通过添加此行让您的 myproject/Android/app/build.gradle 看到它们）

 buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.release //If in debug, change release to debug

        minifyEnabled true
        useProguard true
        shrinkResources true

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' //I add this line...
    }
}

清理您的项目并运行或生成您的 APK。
