Question

我在Android Studio中生成签名APK时遇到问题。几天前工作正常，我不知道出了什么问题。对于我尝试生成签名APK的任何项目，我收到此错误：

警告：处理任务java.io.IOException时出现异常：无法写入[/ Users / bhaveshmisri / Downloads / littleone-dagger-mvp / app / build / intermediates / transforms / proguard / release / jars / 3 / 1f /main.jar]（无法读取[/ Users / bhaveshmisri / Downloads / littleone-dagger-mvp / app / build / intermediates / transforms / RealmTransformer / release / folders / 1/1 / realm（;;;;;; **。类）]（无法阅读[com]（无法阅读[crashlytics]（无法阅读[android]（无法阅读[答案]（无法阅读[shim]（不能阅读[R.class]（重复的zip条目[com / crashlytics / android / answers / shim / R.class]）））））））））

这是我的buildTypes任务：

buildTypes {
    debug {
        shrinkResources false // This must be first
        minifyEnabled false   // This must be after shrinkResources
        multiDexEnabled true
        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules-debug.pro"
    }
    release {
        shrinkResources true
        minifyEnabled true
        useProguard true
        multiDexEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), "proguard-rules.pro"
    }
}

以下是我在proguard文件中编写的代码：

Answer 1

您是否尝试过将proguard用于发布版本？

release {
    shrinkResources false
    minifyEnabled false
    useProguard false
    multiDexEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), "proguard-rules.pro"
}

如果这样，你应该修复我们的proguard配置

Answer 2

尝试排除answer-shim：

compile ('io.branch.sdk.android:library:2.+') {
    exclude module: 'answers-shim' 
}

Answer 3

尝试在proguard文件中添加以下行，以忽略您获得的警告。

-dontwarn com.crashlytics.android.answers.shim.**

Answer 4

问题出在答案库中。最新版本似乎有问题。当我将库降级到

时

compile('io.branch.sdk.android:library:2.5.9') { exclude module: 'answers-shim' }

它工作正常。

Answer 5

问题

在我之后发生了同样的问题：

升级到Android Studio 3，然后
在我的依赖库中，将内联类更改为lambda和方法引用。

我认为我可以自由地使用Android Studio 3发行说明中所述的lambdas和方法引用，我可能已经忘记或错过了它。

解决方案：

无论如何，我不是百分百肯定，但我认为我们仍然无法在项目库中使用lambdas和/或方法引用，因为只要我恢复了库中的所有lambdas和方法引用，我成功地重新生成了我的APK。

无法在Android Studio中生成已签名的APK，'java.io.IOException'
