Android code obfuscation and project announcement step recorder

Originally put together the Android project was confused with the published file. I suddenly thought, why not write blog, share. There are cases of this article.

Android code obfuscation and project announcement step record

First, clean up the debugging information in the code, such as log, System.out

Second, change the version number in the manifest file to the current version number, if you need to update the database, you need to change the program database version number in the configuration class or configuration file.

Third, set the project's debugable to False in the manifest file

Iv. creating a signing certificate KeyStore file

V. Add the statement proguard.config=proguard-project.txt to the Project.properites file in the project to specify the obfuscation rule file

Vi. Configuration of Proguard-project.txt files

Suppose the project References library project. Then eclipse should actively produce android.library.reference.1 in the project.properties file itself. N=. /libraryprojectname

Eight, Suppose the project includes svntmp ( usually in the bin directory of the project ) . It should be removed in a timely manner , or it will cause packaging to fail.

Nine, the project packaging, installation test ( preferably using an existing build package for the upgrade Test )

Attached: Demo sample Proguard-project.txt file and corresponding instructions:

# This was a configuration file for Proguard.

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

# optimizations:if you don ' t want to optimize, use the

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

# Turns off the optimization flags. Adding Optimization introduces

# Certain risks, since for example no all optimizations performed by

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

# off various optimizations known to has issues, but the list could not

# is complete or up to date. (the "Arithmetic" optimization can be

# used if you is only targeting Android 2.0 or later.) Make sure

# Test thoroughly if you go the this route.

File Description:

0. The above documents are copied from the project I have developed today. For project protection purposes, the project package name has been replaced with com.wly.xxx, and readers can change it based on their own projects!

1. The blue content has the general nature, can copy the paste;

2. The orange content is used to specify the jar files in the program (the library project that can see the references does not need to be included because they are already specified in the Project.Properties file).

3. The red content is used to represent the contents of the jar package that is reserved (not confused) for reference.

4. Green Grass content is used to indicate that the entity class under the Bean file reserved locally is not confused.

5. Purple content is used to indicate that classes that retain local reflection are not confused.

6. Green content for special handling of Web JS local native call processes should not be confused between components.
