我是第一次测试 Proguard 的混淆功能。为此，我做了以下
- 下载了 Cordova Hello World 插件
- 通过将字符串添加
" This is top secret"到它发出的问候消息来修改它 - 创建了一个简单的 Cordova Hello World 项目
cordova create ... - 添加了Cordova Proguard 插件
- 将本地来源的插件添加到该项目中
platforms\android\project.properties通过追加修改文件proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-custom.txt- 构建了apk
cordova build --release
我proguard-custom.txt基本上没有动过文件。其内容如下图

Proguard 按预期完成所有动作。例如，我看到
Obfuscating...
Printing mapping to
[buildpath\outputs\mapping\release\mapping.txt]...
Preverifying...
Writing output...
Preparing output jar
[buildpath\intermediates\transforms\proguard\release\0.jar]
Copying resources from program jar
[buildpath\intermediates\transforms\desugar\release\0.jar]
(filtered)
Copying resources from program directory
[buildpath\intermediates\transforms\desugar\release\1]
(filtered)
Copying resources from program jar
[buildpath\intermediates\transforms\mergeJavaRes\release\0.jar]
(filtered)
并且 APK 按预期生成。我通过这个Java 反编译器运行了这个 APK并下载了输出。浏览到Hello.java那个下载我找到了完整的原始源代码
package com.example.plugin;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
public class Hello extends CordovaPlugin
{
public boolean execute(String str,JSONArray jSONArray,
CallbackContext callbackContext)
{
if (!str.equals("greet")) return false;
callbackContext.success("Hello, " + jSONArray.getString(0) +
" This is a secret!");
return true;
}
}
就好像 Proguard 经历了所有的动作，但什么都没有。我显然错过了这里的一个关键步骤，但我不清楚那可能是什么。我将非常感谢任何能够让我走上正轨的人。
