proguard obfuscation

Android project source code obfuscation SolutionConsidering the code security, it is easy for others to steal their work. Today, I am eager to learn about Android code obfuscation. I want to help my friends who are learning android to avoid detours in the future.Because my android project version is 1.6, Google added support for code obfuscation to 2.2 and later

Originally compiled a copy of the Android project to confuse and publish the document, suddenly think of why not write a blog, share it, if it has this article.Android code obfuscation and project release steps recordFirst, clean up the debugging information in the code, such as log, System.outSecond, modify the version in the manifest file to the current version, if you need to update the database, you need to modify the program database version in t

The first step: code obfuscation (note the introduction of the Third-party jar) When you create a project in a new version of ADT, the files for the mixed code are no longer proguard.cfg, but Project.Properties and Proguard-project.txt. When you create a new project, you automatically generate project.properties and proguard-project.txt files without creating y

Android Application (apk) code obfuscation notes Project. properties # This file is automatically generated by Android Tools.# Do not modify this file -- YOUR CHANGES WILL BE ERASED!## This file must be checked in Version Control Systems.## To customize properties used by the Ant build system edit# "ant.properties", and override values to adapt the script to your# project structure.## To enable ProGuard to

1. Currently some tools, such as Apktool,dextojar, can be used to decompile our Android installation package to obtain the source code . In order to reduce being cracked, resulting in source code leakage, the program was stolen by others, and so on. We need to confuse the code , the Android SDK provides us with the proguard tool that can confuse the code (usually renamed with a meaningless name), and remove unused code, optimize and compress the progr

Problem Overview: Create an androidProgramThe following error occurs: The/Android-SDK-Windows/tools/lib/proguard. cfg file is not found. Cause: The SDK is incomplete. Solution: Method 1 You can create a proguard. cfg file in the/Android-SDK-Windows/tools/lib/directory. Add the following content: Proguard. cfg Method 2 Upda

Code obfuscation + Signature packaging in Android studio environmentThe author mr_ Mr. Feng's concern 2016.08.21 01:10 Words 1040 Read 734 comments 5 likes Note: The version of Android Studio used in this article is 2.1.2.To do a company project, you need to code the project to confuse + signature packaging, and then a variety of collection to view data, is a small result. The weekend is nothing to think of summing up the later use can do refe

Only for the record.Java code can be anti-compilation, so sometimes to protect their own intellectual property is really a bit of thought, generally speaking, there are three ideas: 1, the class file encryption, this is the safest, but also cost things, because to rewrite the ClassLoader to uncover class files; 2, using flower instructions, The class file cannot be deserialized (using the Anti-compilation Tool vulnerability); 3, code confusion, improve code reading cost, simple and easy to opera

Currently, new technologies such as Hibernate and spring are managed using configuration files. When we use obfuscators, we only confuse java files, which will inevitably leadAfter Java obfuscation, the information in the configuration file cannot correspond to the class name and method name in Java. Therefore, it must be noted that those files are not involved in obfuscation. FirstThe progurand obfuscators

In order to prevent the results of their own work stolen by others, confusing code can effectively prevent the anti-compilation, the following to summarize the following steps to confuse the code:2, edit the Proguard-project.txt under the project, add the rules that do not need to be confused (model, generics, reflection, third-party jar package), the contents of the Proguard-project.txt file are as follows

When we compile the user version of the Android system, sometimes there will be proguard errors, in resolving this error, we need to know some knowledge:What is 1,proguard used for?Simply put, he is a tool used to confuse Java code.2, where is this thing implemented?We generally support it in the Android.mk file, such as:1) Specify the Proguard.flags file for native methods and variables that do not need to

Meituan Android resource obfuscation protection practicesPreface APK security in Android applications has been criticized, and the market is filled with various cracked or Chinese applications, hackers can easily decompile, crack, and convert an APK using a cracking tool, in this way, the logic of the original code can be modified, new code can be added, resources can be added or modified, or even more viruses can be implanted, thereby compromising th

Today, there's a problem with packing: Duplicate zip entry error.It's really a lot of disgusting.When using Ant to package:ErrorI got the following error at-obfuscate stepThrough my day's efforts: At last solved the problem.The problem is that a jar package in my project has been referenced several times. This time Proguard, will be error. This Ken is going to need to be optimized. At present we can only manually delete the extra jar package!My soluti

Android code obfuscation is a must, Java layer code if not confused equals to the source code to send people. So how do you confuse it?Previously, it was generally mentioned that Proguard.cfg was used, but the new version of ADT did not have the file, and instead it was the Proguard-project.txt file. So how do you use it?In the project root directory there is a project.properties, which has the following co

Like Android developed in the Java language, it is easy to be compiled by others, the equivalent of a bare-Ben, especially for commercial purposes, to prevent anti-compilation is necessary measures. Code obfuscation is a good way to prevent anti-compilation. 1, the code of the APK is confused. In the Eclipse development environment, use the proguard obfuscation t

Android code obfuscation is a must, Java layer code assumes that does not confuse equals the source code to send the person.So how do you confuse it?Previously, the use of proguard.cfg was generally mentioned, but the new version number ADT does not have this file. Instead, it is the Proguard-project.txt file.So how do you use it?There is a project.properties under the project root folder. Inside there are

There are a lot of nonsense examples on the Internet. Here I will combine them to make your method variable a, B, c, d, f ...... Combined with my example: http://blog.csdn.net/zxciop110/article/details/8706153 Obfuscation of Android is nothing more than Java, because the Android Application layer is Java JavaCodeIt is easy to decompile. The following uses proguard to protect our code.

For the APK using the signature, it is often possible to see the code implementation of the class file after the anti-compilation that is used frequently. For anti-compilation viewable personal blogs click the open linkThe use of code obfuscation can be such a normal anti-compilation failure. Many other confusing mechanisms are found on the official website http://developer.android.com/guide/developing/tools/proguard.html1. In Build.grandle, the rules
