How to use ant to achieve automatic packaging android, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Android's ProGuard is located in android sdk's tools/proguard directory. If there is an error when integrating a third-party sdk, it is recommended to update it to the latest ProGuard. Download address: http://sourceforge.net/projects/proguard/files/

The Proguard tool goes through the shrinks, optimizes, obfuscates, and preverify steps to remove junk code while renaming class variables and methods using obscure semantics. Proguard-processed code is not easily reversed and reduces the size of the apk file.

Proguard is integrated into android's build system, so there is no need to call it manually. If you need to use ProGuard, you only need to configure proguard.config=proguard.cfg in the / 'project.properties file if the proguard.cfg file exists in the current project directory, or if you specify a specific directory of the file. ProGuard obfuscation code is used only in release mode.

The files that will be generated after executing ProGuard:

1) dump.txt describes the internal structure of all classes in the apk file

2) mapping.txt lists the correspondence between original and confused classes, methods, and properties

3) seeds.txt lists classes and attributes that are not confused

4) usage.txt lists the code that has not been typed into the apk file

These files are placed in the / bin/projuard directory if you are using the ant tool or / proguard directory if you are using eclipse

Debug confusing code

Retrace.bat | retrace.sh-verbose mapping.txt obfuscated_trace,txt, so be sure to save the mapping,txt file.

This is the answer to the question about how to use ant to automatically package android. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
