android - 当我尝试生成 APK 版本时出现问题

Question

当我尝试生成 APK 版本时，这个问题就出现了。

构建输出

“DuplicatePlatformClasses”类型问题的解释：有许多库不仅复制了 Android 平台的功能，而且使用了与 Android 中提供的完全相同的类名——例如 apache http 类。这可能会导致意外崩溃。

要解决此问题，您需要找到不再存在此问题的库的较新版本，或者使用 jarjar 工具之类的工具重新打包库（及其所有依赖项），或者最后重写代码以使用不同的API（例如，对于 http 代码，请考虑使用 HttpUrlConnection 或类似 okhttp 的库）。

    id 'com.android.application'

        packagingOptions{
            exclude 'META-INF/DEPENDENCIES'

        }

        targetSdkVersion 30

         vectorDrawables.useSupportLibrary = true
    }

        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
        }
    }
