android - Proguard 不会混淆 Android 中的代码

Question

我试图使用混淆器混淆我的代码。构建发布 apk 时，它会生成 apk，但代码不会被混淆。请检查我的代码并提供解决方案。

构建.gradle

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}


android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    useLibrary 'org.apache.http.legacy'

    packagingOptions {
        exclude 'LICENSE.txt'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/LICENSE.uas.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }

    defaultConfig {
        applicationId "com.infolabs.tv"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile files('libs/ez_cast_sdk_v_2.1.109.jar')
    compile files('libs/gson-2.4.jar')
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.github.d-max:spots-dialog:0.4@aar'
    compile 'com.jakewharton:butterknife:6.1.0'
    compile 'com.android.support:design:23.3.0'
    compile files('libs/Parse-1.8.0.jar')
    compile 'com.github.satyan:sugar:1.4'
    compile 'de.greenrobot:eventbus:2.4.0'
    compile('com.crashlytics.sdk.android:crashlytics:2.5.7@aar') {
        transitive = true;
    }
}

这是我的 proguard-rules.pro 文件

Answer 1

您的混淆器配置中有各种过于通用的规则，即保留几乎所有内容。

此规则保留每个公共(public)类中的每个公共(public)或 protected 字段/方法(这样的规则仅对库有用):

-keep public class * {
    public protected *;
}

此规则保留包 com 及其子包中的每个类/接口(interface):

-keep class com.** { *; }
-keep interface com.** { *; }

假设您的应用程序包也以 com. 开头，这将防止您的应用程序中的任何内容被混淆。
