Question

启用了proguard的Android Studio中的CrashLytics测试项目不会混淆类和方法名称。正如您在提供的规则文件中看到的那样，我没有使用任何规则＆＃34; proguard-rules.pro＆＃34;。

我做错了什么？
是否有用于解释Proguard规则的参考文档或教程？

的build.gradle

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        // These docs use an open ended version so that our plugin
        // can be updated quickly in response to Android tooling updates

        // We recommend changing it to the latest version from our changelog:
        // https://docs.fabric.io/android/changelog.html#fabric-gradle-plugin

proguard-rules.pro

 # Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in D:\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# 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 {
#   public *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.

的更新

好的，我不能混淆Activity名称，因为它应该通过Manifest文件引用，但是onCreate和forceCrash的方法名称怎么样，为什么它们仍然是可读的？

import io.fabric.sdk.android.Fabric;
import com.crashlytics.android.Crashlytics;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Fabric.with(this, new Crashlytics());
    setContentView(R.layout.activity_main);
}

public void forceCrash(View view) {
    throw new RuntimeException("This is a crash");
}

}

Answer 1

替换

proguardFiles 'proguard-rules.pro'

与

对齐

getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

Answer 2

你没有做错任何事。您的大多数代码都显然是混淆的 - 屏幕截图中的b，a和c类是。您的构建中会生成默认的ProGuard规则 - 您可以在项目的build \ intermediates \ proguard-files \文件夹中找到它们。由于此答案中解释的原因，活动名称未被混淆ProGuard Still Displays Full Activity Name

活动名称永远不会被混淆，因为它们在manifest.xml中被引用。和android通过反射访问这些活动，因此无法更改其名称）
使用ProGuard规则在Android文档中进行了说明 - https://developer.android.com/studio/build/shrink-code.html，在ProGuard手册中https://www.guardsquare.com/en/proguard/manual/usage，最近有一篇关于ProGuard疑难解答的好文章 - https://medium.com/google-developers/troubleshooting-proguard-issues-on-android-bce9de4f8a74

Answer 3

显然，实际上没有人混淆活动名称。但是，您可以手动更改它。只需将其名称修改为所需的名称即可。

对于混淆的方法和类，只需使用：

-obfuscationdictionary file.txt
-classobfuscationdictionary file.txt

无法使用Proguard模糊类和方法名称
