我试图用混淆器混淆代码,所以我在发布构建类型中启用了minify
:
buildTypes {
debug {
minifyEnabled false
}
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt')
}
}
但是当我生成“release apk”并安装它后,应用程序运行变慢(滞后)..为什么在启用 minify 的情况下会发生这种情况? 这是我的依赖项:
dependencies {
compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:palette-v7:25.3.1'
compile 'com.google.protobuf.nano:protobuf-javanano:3.0.0-alpha-2'
compile 'com.jrummyapps:colorpicker:2.1.6'
compile 'org.apache.commons:commons-lang3:3.4'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile project(':library')
testCompile 'junit:junit:4.12'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2'
androidTestCompile 'com.android.support:support-annotations:25.3.1'
}
这是我的proguard-android.txt
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html
-dontusemixedcaseclassnames

-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
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.
-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {

}
# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {

}
# We want to keep methods in Activity that could be used in the XML attribute onClick

}
# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version. We know about them, and they are safe.
-dontwarn android.support.**
# Understand the @Keep support annotation.
-keep class android.support.annotation.Keep
-keep @android.support.annotation.Keep class * {*;}
-keepclasseswithmembers class * {
@android.support.annotation.Keep <methods>;
}
-keepclasseswithmembers class * {
@android.support.annotation.Keep <fields>;
}
-keepclasseswithmembers class * {
@android.support.annotation.Keep <init>(...);
}
我尝试添加:
-keep class com.mylibrary.**
-keep interface com.mylibrary.**
-keep enum com.mylibrary.**
我的库依赖:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:palette-v7:25.3.1'
testCompile 'junit:junit:4.12'
compile 'com.google.code.gson:gson:2.8.0'
compile 'org.jetbrains:annotations-java5:15.0'
}
最佳答案
虽然 proguard-android.txt
中的注释指定了一些原因,但我很惊讶地看到禁用某些优化的标志作为默认自动生成的 proguard-android.txt
文件在创建新的 Android 项目时不包含此类标志。尝试删除以下行并查看是否有改进:
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontoptimize
-dontpreverify
文件的其余部分似乎没问题,虽然我没有检查所有正在使用的库,但我检查了几个并意识到您已经为它们添加了必要的异常(exception)。
如果那没有解决,你必须确保正确添加正在使用的库的异常,并检查你的 中的
模块,因为它在依赖项中被引用。proguard-android.txt
