SplashScreenActivity第38行是：

firebaseAuth = FirebaseAuth.getInstance();

我的ProGuard规则包含：

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

我试着到处搜寻，什么也没找到。

我的build.gradle：

 buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.config
        proguardFile 'C:/Users/vikas/Desktop/phzVendor/phzandvendor/app/proguard-rules.pro'
    }
    debug {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        debuggable true
        signingConfig signingConfigs.config
        proguardFile 'C:/Users/vikas/Desktop/phzVendor/phzandvendor/app/proguard-rules.pro'
    }
}

如果将minifyEnabled设置为true，则表示proguard启动正常。您需要为每个lib和应用程序提供正确的proguard配置。

对于firebase，您可以找到配置here或official docs

here is一个项目，为proguard配置收集许多有用的片段。

将minifyEnabled设置为true后，我收到以下错误
