Android Studio无法生成签名APK。

Question

问题是，我在使用 Allatori Java 混淆器生成 Signed APK 时遇到了错误。我尝试了不同的方法，如清除缓存/重启、删除构建文件夹、重新构建项目、字符串、甚至尝试比较包名、类命名约定、可能的 jars、弃用的方法或类，但都无济于事！Multi Dex 也已启用！我尝试了每一个可能的解决方案，但无法生成 signed APK。

apply plugin: 'com.android.application'
apply plugin: 'ensighten'

    supportVersion = "25.3.1"
    googleServices = "11.4.2"
}

android {

    def version = "2.0.0"
    compileSdkVersion 25
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId "removed"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 20
        versionName "${version}"
        multiDexEnabled true


        def today = new Date().format('yyyyMMdd_HHmmss').toString()
        project.ext.set("archivesBaseName", "MyApplication_Android_Build_"+ today + "_Version " + version);

它正在显示4个错误，请您发布完整的错误信息。 - lib4backer

可能是重复的问题：Android- Error:Execution failed for task ':app:transformClassesWithDexForRelease' - Yuliwee

@Yuliwee 不，它不是！ - Atif AbbAsi

那么你已经尝试了提到的帖子中的所有解决方案，但都没有起作用吗？ - Yuliwee

签名的 APK 应该是发布版本，你是在尝试调试还是发布版本？由于异常显示类路径指向调试版本，请确保所有模块都处于发布模式。 - lib4backer

Answer 1

据我所知，您正在使用许多库，并使用Allatori Java混淆器。由于Allatori混淆，您的Java代码未能正确转换为字节码，这就是您无法生成已签名apk的原因。尝试快速的hack方法，删除构建文件、Gradle文件，并将项目无效化并重启多次。

希望这可以帮助您 :)

Gradle中没有您添加的签名配置，因此首先需要创建密钥库（https://developer.android.com/studio/publish/app-signing.html）

然后将其添加到应用级别的Gradle中

signingConfigs {
    release {
        // For making app store release config below parameters
        storeFile file('path to keystore')
        storePassword "keystore password"
        keyAlias "Alias_of_keystore"         
        keyPassword "Keystore Password"   
    }
}

然后在构建类型中添加

 buildTypes {
    // For  app store release uncomment below and select release build flavor in Build Variants
    release {
...
signingConfig signingConfigs.release
}}
