混淆(minifyEnabled为true)在Debug and Release中不起作用 [英] Obfuscation (minifyEnabled true) not working in Debug and Release
本文介绍了混淆(minifyEnabled为true)在Debug and Release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
在调试和发布模式下，我无法使用minifyEnabled true运行apk.我引用了以下链接，但没有一个对我有用.
I cannot able to run apk using minifyEnabled true in Debug and Release mode.I have referred below links but none worked for me.
1. Android-错误:任务':app:transformClassesWithDexForRelease的执行失败'
2.将字节码转换为dex时出错:原因:java.lang.RuntimeException:异常解析类-Android Studio 2.0 beta 6

我正在使用Android Studio 1.5.1，这个Android Studio版本是否对混淆很重要(minifyEnabled为true)? 是否有用于加密APK的在线或离线工具? 请给我建议. 我在此上浪费了很多时间. 请帮助我.谢谢.
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.
推荐答案
好吧...正如您尚未提到的那样，对蚂蚁来说，为了保护您的应用程序，这就是为什么它无法对其进行混淆的原因.明确使用
useProguard true
是否需要一个简单的应用gradle构建文件示例...?在下面找到它，因为它是我的项目:
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'
}
现在措辞是什么意思: 它只会在项目发布时
obfuscate您的代码；这意味着您必须构建自己的发行版APK.
Now what it means in wording : It will only
obfuscateyour code in release of your project; which means you have to build your release apk.
如何测试...?混淆是否发生?
我们在这里...
How to test...? obfuscation happened or not?
Here we go...
- 从linux或mac os终端解压缩apk文件为:解压缩apk_name
- 您将提取项目文件...查找dex文件
- 使用dex2jar将其转换为jar
- 使用JD-UI应用读取该jar文件
- 您将看到所有Java类和核心代码文件
- 是的..看起来很整齐..它是一个代码....但是混淆不清
嗯...希望对您有帮助
Hmmmm... Hope it helps
2
在保护规则文件中...不要试图像编写代码一样对它进行编程，只保留一些不重要的类，如: -保持公共类OpenSource
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
就这样.
最重要的是，作为初学者，您应该而且必须使用android studio或任何IDE设置的默认pro-guard文件；在创建项目时.就像:
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'
4
创建一个新的示例项目，学习如何实施任何概念是一个好习惯，一旦我们动手并清除了该概念...，打开主项目并在...之内实施. ..到目前为止，我们已经掌握了这一概念.
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.
始终建议使用Android Studio，而不要使用其他任何IDE，因为它是由google正式宣布为android的Google.而且它必须是最新的且更新的IDE，且启用了最少的api 26.正如Google上周强制规定的那样，要在google play应用上上传应用，必须以api级别26为目标.
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.
此外，由于所有最新依赖项以及补丁都在其中，这对您的项目也将有所帮助，从而确保其无错误构建.
Also it helps to your project to get it build error free as all the latest dependencies are there along with patches.
