如何为 android apk 添加代码混淆。我用了proguard但仍然看到来自应用程序的代码decompiler.

我像这样添加了progruad

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

反编译后它可以看到我的所有代码和类。反编译后 https://i.stack.imgur.com/CiiVQ.png

我的 Proguard 文件在此输入图像描述 https://i.stack.imgur.com/7bEu0.png

使用下面的代码来获取您的解决方案。

android {
    buildTypes {
            debug {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
                zipAlignEnabled true
                shrinkResources false
            }
            release {
                debuggable false
                // Enables code shrinking, obfuscation, and optimization for only
                // your project's release build type.
                minifyEnabled true

                // Includes the default ProGuard rules files that are packaged with
                // the Android Gradle plugin. To learn more, go to the section about
                // R8 configuration files.
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

                zipAlignEnabled true

                // Enables resource shrinking, which is performed by the
                // Android Gradle plugin.
                shrinkResources true
            }
        }
     }
