Anti-compilation app method

If you don't have the code, you can decompile the app.

There will be 2 tools, Dex2jar and Jd-gui, respectively. Here you can download the latest version as well as the sample apk.

We take the contactmanager.apk in the toolkit as an example and briefly describe the process of anti-compilation.

• 1, rename contactmanager.apk to Contactmanager.zip and unzip to get file Classes.dex;
• 2, unzip the Dex2jar-0.0.9.15.zip and enter the folder from the command line;
• 3, Run command

D2j-dex2jar.bat Path_to\classes.dex

Get Classes-dex2jar.jar under the current folder;

• 4, decompression jd-gui-0.3.6.windows.zip get file Jd-gui.exe;
• 5, open Classes-dex2jar.jar with Jd-gui.exe;

Well, well, you can enjoy it.

The contactmanager shown here is the main activity of the app under test.
