Question

我有以下build.gradle文件

` 应用插件：“ com.android.application” 应用插件：“ com.google.gms.google-services”

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.anuj.auth"
        minSdkVersion 16

        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    buildToolsVersion '28.0.3'
}

    implementation fileTree(include: ['*.jar'], dir: 'libs')

我已经启用了proguard规则，但是即使我将proguard-rules.pro留空，也会出现以下错误。我对proguard的概念是陌生的，并且感到很困惑。

这是我在启用proguard规则的情况下构建应用程序时收到的消息。

Answer 1

minifyEnabled true启用proguard。因此，您有2个选择： 1.如果您不需要保护者，则将其设置为false 2.否则，您需要为引起问题的库编写proguard规则。您可以在Git上轻松获得它们。

Proguard构建失败，并添加了外部库
