【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' 【发布时间】:2018-01-05 08:46:29 【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
我试图把我可以放在proguard.pro的每一个该死的东西中:

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'
