Android code obfuscation and project release method record

Android code obfuscation and project release method record
Zookeeper Android code obfuscation and project release procedure record

I have compiled a document for obfuscation and release of the Android project. I suddenly thought about writing a blog and sharing it. If so, I will have this article.

Android code obfuscation and project release procedure record

1. Clear debugging information in the Code, such as Log and System. out.

2. Modify the version to the current version in the configuration file. to update the database, modify the database version in the configuration class or configuration file.

3. Set the debugable of the project to false in the configuration file.

4. Create a signature certificate keystore File

In the project project.properitesfile of the project, the syntax sentence proguard.configpolicproguard-project.txt is used to specify the obfuscation rule file.

Configure the proguard-project.txt file in Step 6

7. If the Project references the Library project, Eclipse will automatically generate android. library. reference.1.. n = ../LibraryProjectName in the Project. properties file.

8. If the project contains svntmp (usually located in the bin folder of the project), delete it in time during packaging. Otherwise, packaging may fail.

9. Package and install and test the project (it is best to use the existing generated package for upgrade testing)

Appendix: proguard-project.txt and related instructions:

# This is a configuration file for ProGuard.

# Http://proguard.sourceforge.net/index.html#manual/usage.html

# Optimizations: If you don't want to optimize, use

# Proguard-android.txt configuration file instead of this one, which

# Turns off the optimization flags. Adding optimization introduces

# Certain risks, since for example not all optimizations saved med

# ProGuard works on all versions of Dalvik. The following flags turn

# Off various optimizations known to have issues, but the list may not

# Be complete or up to date. (The "arithmetic" optimization can be

# Used if you are only targeting Android 2.0 or later.) Make sure you

# Test thoroughly if you go this route.

File description:

0. The above files are copied from the project developed by the author. For the purpose of project protection, the project package name has been replaced by com. wly. xxx. You can modify it based on your project!

1. The blue content is generic and can be copied and pasted;

2. The Orange content is used to specify the jar files used in the Program (you can see that the referenced Library Project does not need to be included because they have already been specified in the project. properties file ).

3. The red content is used to indicate the content in the referenced jar package that is retained (not obfuscated.

4. The grass green content is used to indicate that the entity classes under the Local bean file are not obfuscated.

5. The Purple content is used to indicate that classes with local reflection are not obfuscated.

6. The green content is used to deal with the call process between Web JS and local native components in particular.
