本文介绍了混淆(minifyEnabled true)在调试和发布中不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我无法在调试和发布模式下使用 minifyEnabled true 运行 apk.我参考了以下链接，但没有一个对我有用.

我使用的是 Android Studio 1.5.1.这个 Android Studio 版本是否对混淆很重要(minifyEnabled true)?是否有任何用于加密 APK 的在线或离线工具?请建议我.我在这上面浪费了很多时间.请帮我解决这个问题.提前致谢.

解决方案

嗯......正如你还没有提到的，对蚂蚁来说，为了保护你的应用程序，这就是它无法混淆它的原因.明确使用useProguard true

<小时>

需要一个简单的应用程序 gradle 构建文件示例...?在下面找到它，因为它是我的项目:

应用插件:'com.android.application'安卓 {compileSdkVersion 26默认配置{applicationId "com.xxxxxxxxxxcccccccvvvvvv.apps.firebase"minSdk 版本 16目标SDK版本26版本代码 1版本名称1.0"testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"}构建类型{发布 {minifyEnabled true使用Proguard trueproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'收缩资源真}}}依赖{实现文件树(目录:'libs'，包括:['*.jar'])实现 'com.android.support:appcompat-v7:26.1.0'实现 'com.android.support:design:26.1.0'实现 'com.android.support.constraint:constraint-layout:1.1.2'实现 'com.firebase:firebase-jobdispatcher:0.8.5'testImplementation 'junit:junit:4.12'androidTestImplementation 'com.android.support.test:runner:1.0.2'androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'}

<小时><块引用>

现在它的措辞是什么意思:它只会在您的项目发布时混淆您的代码；这意味着您必须构建您的发布 apk.

如何测试...?混淆发生与否?

我们开始...

  1. 从 linux 或 mac os 终端解压 apk 文件为:unzip apk_name
  2. 您将提取您的项目文件...找到 dex 文件
  3. 使用dex2jar转成jar
  4. 使用 JD-UI 应用程序读取该 jar 文件
  5. 您将看到所有 Java 类和核心代码文件
  6. 是的......看起来很整洁......它是一个代码......但有混淆

<块引用>

嗯...希望有帮助

2

在 pro-guard 规则文件中...不要尝试像代码一样对其进行编程，只需保留一些不那么重要的类:- 保持公共类开源

就是这样.

3

最重要的是，作为初学者，您应该并且必须使用由 android studio 或任何您的 IDE 设置的默认 pro-guard 文件；在创建项目时.喜欢:

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

4

创建一个新的示例项目，学习如何实现任何概念是一个好习惯，一旦我们动手并清除了概念...，打开主项目并在...内实现它，作为... 到目前为止，我们已经掌握了这个概念.

5

始终建议使用 Android Studio 而不是任何其他 IDE，因为它是由 google 正式发布的，因为 android 是..并且它必须是最新的和更新的 IDE，并且至少启用了 api 26.由于谷歌上周强制要求在谷歌播放应用程序上上传应用程序必须针对 api 级别 26.

此外，它有助于您的项目使其无构建错误，因为所有最新的依赖项都与补丁一起存在.

I am using Android Studio 1.5.1.Is this Android studio version matters for obfuscation (minifyEnabled true) ? Are there any online or offline tools for encrypting the APK ? Please suggest me. I have wasted a lot of time on this. Please help me with this.Thanks in Advance.

解决方案

Well... As you haven't mentioned yet, to the ant, to pro-guard your app, That's why it is not able to obfuscate it. Use explicitly useProguard true

Need a simple example of app gradle build file...? Find it below as it is of my project :

apply plugin: 'com.android.application'

android {
compileSdkVersion 26
defaultConfig {
    applicationId "com.xxxxxxxxxxcccccccvvvvvv.apps.firebase"
    minSdkVersion 16
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        shrinkResources true
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.firebase:firebase-jobdispatcher:0.8.5'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Now what it means in wording : It will only obfuscate your code in release of your project; which means you have to build your release apk.

How to test...? obfuscation happened or not?

Here we go...

  1. Unzip apk file from linux or mac os terminal as: unzip apk_name
  2. You will get your project files extracted... find dex file
  3. Use dex2jar to convert it into jar
  4. Read that jar file with JD-UI app
  5. You will see all your java classes and core code files
  6. Yes.... look neat.... Its a code.... But with obfuscation

Hmmmm... Hope it helps

Edit : 2

In the pro-guard rules files... Do not try to program it like code, just keep some classes which are not so important as : -keep public class OpenSource

Thats it.

Edit : 3

Most importantly you should and must as a beginner use default pro-guard file set by android studio or whichever your IDE; while creating the project. like :

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

Edit : 4

It is a good habit to create a new sample project, learn how to implement any concept, once we are hands on it and cleared the concept..., Open the main project and implement it within..., As ... As of now , we are mastered the concept.

Edit : 5

It is always recommended to use Android Studio than any other IDE as it is officially by google as android is.. And it must be latest and updated IDE with minimum api 26 enabled. as google made compulsory last week that to upload apps on google play apps must target api level 26.

Also it helps to your project to get it build error free as all the latest dependencies are there along with patches.

这篇关于混淆(minifyEnabled true)在调试和发布中不起作用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
