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
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
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
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
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.

Role, use, and Bug Analysis of proguard This article mainly describes the functions, usage, and Bug Analysis of proguard.1. Role of proguardBy deleting useless code, proguard renames the class name, method name, and attribute name in the Code with obscure names to achieve code obfuscation, compression, and optimization, similar to JavaScript obfuscation and compr

Because of the cross-platform requirements, Java bytecode contains a lot of source code information, such as variable name, method name, and through these names to access variables and methods, these symbols

To achieve code obfuscation, the method is as follows: Because both my SDK and adt00000.1 are up-to-date, I have read the proguard. cfg obfuscation code method provided on the Internet,. It is said that proguard. cfg will be automatically generated under the project file, but I cannot generate it, so I cannot use this method, which is a headache.

Overview of the Proguard Code obfuscation tool: code can be de-redundant compression, code optimization, code obfuscation and so on. The main application in Android is to confuse the code: the class name, method name, field name into difficult to read and understand names such as a,b,c or three-way, in order to prevent reverse engineering and be anti-compiled reading source.Enable eclipse with Proguard: The
