proguard security

Android code obfuscation 1 proguard. cfg. This is the proguard script required for obfuscation. The Code is as follows: [java] view plain-optimizationpasses 5-dontusemixedcaseclassnames-dontskipnonpubliclibraryclasses-dontpreverify-verbose-optimizations! Code/simplification/arithmetic ,! Field /*,! Class/merging/*-keep public class * extends android. app. activity-keep public class * extends android. app. a

Just touch Android, not very familiar. After discovering that items that can be packaged properly before adding confusion and then packaging the signature apk, you are prompted with "Android Proguard failed to export application".Comment out the proguard.config=proguard.cfg in the program (in the Project.Properties file), and then package the discovery without confusion to properly package.Finally found the reason, originally upgraded the SDK to 20.3

Android Developers: ProGuard, androidproguard By deleting unused code, the ProGuard tool uses a semantic fuzzy name to rename classes, fields, and methods to reduce, optimize, and confuse your code. The result is a smaller. APK file that is more difficult to reverse to the project. Because ProGuard makes your application more difficult to reverse engineer, it is

Android Proguard: androidproguard Generally, code encryption is required for commercial projects. Android provides a code obfuscation method, which is described as follows: I. Introduction 1. Introduction Obfuscators compress, optimize, and confuse code by deleting unused code and renaming classes, fields, and methods with obscure names. The result is a relatively small .apk file, which is difficult to reverse engineer. Therefore, obfuscators are an i

JNI is used in the android project. When proguard is used, it is found that many variables cannot be found in the native method. It was originally optimized by produard. Therefore, use progurad with caution in JNI applications. Solution:1. Add a line to Android. mk:Local_proguard_flags: =-include $ (local_path)/proguard. flags2. Create the proguard. Flag file to

When we develop java, we usually encounter code problems that protect our development. Because java is based on jvm, it is easy to decompile class files. Assume that we have developed a web program and released it to the customer. In fact, the customer can easily decompile our source code, including all src files and jsp files. In fact, there are several methods to protect our source code: 1. Use the code obfuscator 2. Reload the classloader of the application server. For the first method, there

I. What have code obfuscation been done?1. code obfuscation is usually used to remove unnecessary Code. It is used to rename classes, attributes, and methods with obscure names to reduce the size of the Code, increase the difficulty of decompilation. (If our applications are charged or kept confidential, we need to improve the security of our code through code obfuscation)2. Enable ProGuard in Eclipse1. Che

Proguard is a free Java class file compression, optimization, mixing device. It can help you remove useless classes, fields, methods, and properties, maximize bytecode optimization, and rename classes, fields, and methods with a short, meaningless name. Now that Eclipse has integrated Proguard, you can download the software if you need to use proguard alone.How t

Java-written code is very easy to decompile, but you can use Proguard to do your best to protect our code, Proguard specific use can refer to the official documentation (http://proguard.sourceforge.net/), Write down my configuration now (in actual use) for reference 1. Download Proguard to http://proguard.sourceforge.net/2. Ready to have the jar bag, I'm here fo

In the Android project to use the JNI, when the use of Proguard, found that the native method can not find many variables, the original was Produard optimized out. Therefore, it is prudent to use Progurad in JNI applications.Workaround:1. Add a line to the ANDROID.MK:Local_proguard_flags: =-include $ (local_path)/proguard.flags2. Create a Proguard.flag file that writes classes and methods that do not require progu
