【中文标题】Android proguard 问题：路径可能不是 null 或空字符串。路径=\'空\'

【英文标题】：Android proguard issue: path may not be null or empty string. path='null'Android proguard 问题：路径可能不是 null 或空字符串。路径='空'

【问题描述】：

设置前一切正常

minifyEnabled 为真

和

shrinkResources 真

设置这些值后，每当我运行项目时，我会收到此错误：

Information:Gradle tasks [:app:assembleProdRelease]
Error:path may not be null or empty string. path='null'
Information:BUILD FAILED
Information:Total time: 23.606 secs
Information:1 error
Information:0 warnings
Information:See complete output in console

此错误意味着错误：path可能不是null或空字符串。 path='null' 这是 build.gradle ：

signingConfigs 
            release 
                storeFile file('/home/rishabh/Documents/dekhoJks/release.jks')
                storePassword "XXXXXXX"
                keyAlias "XXXXXXXX"
                keyPassword "XXXXXXXXX"
            
        
        buildTypes 
            release 
                minifyEnabled true
                //proguardFiles fileTree(dir: "proguard", include: ["*.pro"]).asList().toArray()
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
                shrinkResources true
                signingConfig signingConfigs.release

但仍然无法运行我的应用程序。任何我出错的地方的帮助。

【问题讨论】：

我也陷入了困境。 span>

【参考方案1】：

好的，找到了解决方案。只需替换您的硬编码签名配置：

release 
                storeFile file('/home/rishabh/Documents/dekhoJks/release.jks')
                storePassword "XXXXXXX"
                keyAlias "XXXXXXXX"
                keyPassword "XXXXXXXXX"
            

而不是创建单独的 signing.properties 文件：

STORE_FILE=/home/XXX/XXX/XXX
STORE_PASSWORD=XXXXXX
KEY_ALIAS=XXXXXXXX
KEY_PASSWORD=XXXXXXXXX

并在您的 gradle 中使用。 希望对你有帮助！！

【讨论】：

最终没有解决问题。

【参考方案2】：

两种解决方案

使用以下类路径。 （我在使用 2.3.2 版本时遇到此错误。）

classpath 'com.android.tools.build:gradle:2.2.2'

如果您无法更改类路径版本，请禁用拆分 apk 选项以进行临时修复。

【讨论】：

还有其他解决方案吗？

我已经给了你两个选择。你还想要多少？

这两个选项都是临时的。我想知道你是否找到任何真正的解决方案。

【参考方案3】：

升级：

        classpath 'com.android.tools.build:gradle:4.0.0'
