ProGuard真的是保护android应用程序的好方法吗？

Question

Is ProGuard really a good way to protect the android application? I do not think. Please see the following images:

Compile Code

Decompile_Code

Also the variable names did not change and the code is readable easily.

Answer 1

Activity classes are not completely obfuscated. This is because the activities are listed in the manifest and classes referenced there are automagically kept. This is needed because the Android framework accesses these app entry points via reflection.

Read more from here :

The build process runs the tool aapt to automatically create the configuration file bin/proguard.txt, based on AndroidManifest.xml and other xml files. The build process then passes the configuration file to ProGuard. So ProGuard itself indeed doesn't consider AndroidManifest.xml, but aapt+ProGuard do.
