将我的Android项目转换为Kotlin后,我无法构建发布版本,错误似乎与Proguard有关。
我看到了像
这样的155个警告Warning:com.example.app.activity.MainActivity$1: can't find referenced field 'android.view.View decorView' in program class com.example.app.activity.MainActivity
Warning:com.example.app.activity.MainActivity$2: can't find referenced field 'android.os.Handler handler' in program class com.example.app.activity.MainActivity
并且构建失败并带有
Error:Execution failed for task ':MyApp:transformClassesAndResourcesWithProguardForFreeRelease'.
> Job failed, see logs for details
如果我将build.grade中的这些指令从true更改为false,则构建成功。
minifyEnabled true
shrinkResources true
有关问题的建议吗?
编辑:
proguard文件如下:
proguard的-android.txt
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose
# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify
# If you want to enable optimization, you should include the
# following:
# -optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
# -optimizationpasses 5
# -allowaccessmodification
#
# Note that you cannot just include these flags in your own
# configuration file; if you are including this file, optimization
# will be turned off. You'll need to either edit this file, or
# duplicate the contents of this file and remove the include of this
# file from your project's proguard.config path property.

proguard的-rules.txt
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /home/francesc/droids/android-sdk-linux/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {

签名配置的定义如下所示
signingConfigs {
myConfig {
Properties keyProps = new Properties()
keyProps.load(new FileInputStream(file('../release.properties')))
storeFile file(keyProps["store"])
keyAlias keyProps["alias"]
storePassword keyProps["storePass"]
keyPassword keyProps["keyPass"]
}
}
buildTypes {
release {
proguardFiles 'proguard-android.txt', 'proguard-rules.txt'
minifyEnabled true
shrinkResources true
signingConfig signingConfigs.myConfig
}
}

尝试在没有proguard的情况下进行构建,以解决对该问题负责的人。

尝试将@Keep
批注添加到相关的类(例如MainActivity),看看是否有帮助。如果确实如此,则意味着minify正在重命名某些资源,不应重命名该资源,因为其他一些资源希望使用其原始名称。
