java – ProGuard导致应用程序滞后

我正在尝试使用proguard来混淆代码,所以我在发布版本类型中启用了minify：

buildTypes {
    debug {
        minifyEnabled false
    }
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt')
    }
}

但是当我生成’release apk’并且在我安装它之后,应用程序运行速度变慢(滞后)..为什么在启用minify时会发生这种情况？

这是我的依赖：

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
-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
# 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 * {
    native <methods>;
}

# 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 {
   void set*(***);
   *** get*();
}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keepclassmembers class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator CREATOR;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}

# 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>(...);
}

我试着添加：

-keep class com.mylibrary.**
-keep interface com.mylibrary.**
-keep enum com.mylibrary.**

我的库依赖项：

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'
}

虽然proguard-android.txt中的注释指出了一些原因,但我很惊讶看到禁用某些优化的标志,因为默认的自动生成的proguard-android.txt文件在创建新的Android项目时不包含这样的标志.尝试删除以下行,看看是否有改进：

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontoptimize
-dontpreverify

文件的其余部分似乎很好,虽然我没有检查所有正在使用的库,但我已经检查了一对,并意识到你已经为它们添加了必要的例外.

如果没有成功,你必须确保正确添加正在使用的库的异常,并检查库模块中的proguard-android.txt,因为它在依赖项中被引用.
