Question

我使用第三方依赖项。它在调试模式下效果很好，而且如果我使用以下命令生成签名的APK，效果也很好：

 buildTypes {
    release {

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

但在以下情况时崩溃

 buildTypes {
    release {

        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.release
    }
}

Answer 1

只需将这一行放在ProGuard文件上

-keep public class android.support.v4.** { *;}

用您的外部第三方软件包名称替换android.support.v4

Answer 2

最简单的方法是使用R8，只需添加 android.enableR8=true中的gradle.properties

如何在Android中排除ProGuard对外部第三方的依赖性
