Android code obfuscation prevents anti-compilation

To prevent the code from being deserialized, you need to add confusion. Confusion can also be confused by a third-party apk, or by Proguard in Android.

Obfuscation steps:

1, configuration confusion file, the name can be arbitrary, here to use proguard-android, the format is txt.

2. Introduction

Add Proguard.config=proguard-android.txt to the project's Project.Properties file, which is the confusing file written above.

3, the Android default operating environment is the debug mode, is not to execute code confusion. Therefore, you must sign the project so that if you encounter an error while packaging, there may be a problem confusing the file where it was written.
