Proguard 无法读取 android.jar

Question

我只是启用 Proguard (minifyEnabled true) ...当我尝试构建 singed apk 时出现错误：

Cause: invalid entry CRC (expected 0x9aa3fedc but got 0xfeb7201b)

Exception while processing task java.io.IOException: Can't read [D:\AndroidStudio\AndroidStudioSDK\sdk\platforms\android-27\android.jar] (invalid entry CRC (expected 0x9aa3fedc but got 0xfeb7201b))

我的Gradle.app是：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.test.app"
        manifestPlaceholders = [manifestApplicationId          : "${applicationId}",
                                onesignal_app_id               : "*****-****-****-****-***********",
                                onesignal_google_project_number: "REMOTE"]
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 8
        versionName "1.8"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes.each {
        it.buildConfigField 'String', 'SERVER_URL', serverUrl
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

}

}

apply plugin: 'com.google.gms.google-services'

所以我没有改变任何东西，只是 minifyEnabled 从 false 到 true，我得到了错误。

Answer 1

invalid entry CRC (expected 0x9aa3fedc but got 0xfeb7201b)表示文件已损坏。

您必须使用 SDK 管理器卸载并重新安装 API 级别 27，才能解决这个问题。

并可能考虑购买新驱动器 - 或者至少检查完整性，例如。 hddscan.
