The function of the Dalvik bytecode editor is as follows:

The Dalvik bytecode editor is a powerful Android program modifier. It runs on mobile phones and is free, mainly used for localization and cracking. Using this tool requires basic programming experience and knowledge of Android programs. We know that most programs on Android are developed using Java, compiled into bytecode, which makes them easier to crack. Traditional cracking is very cumbersome, requiring a PC, setting up a development environment, decompiling dex code back to Java, modifying it, then compiling it back into dex (which is difficult), and packaging the APK. The Dalvik bytecode editor takes a completely different technical approach. Since Java is compiled into bytecode, and the bytecode documentation is public, it can directly interpret bytecode and modify programs without the tedious decompiling/compiling process, and without Java's complex development environment (tools like Yagami's APK editor exist, but they are paid).

Function: Modify paid number.

Untested. Everyone should test it themselves.

I am not providing rare Android game cracks yet... including most emulators... I will post them when I play on an Android device.

(Fixed signature issues, fixed string escape issues, added class renaming feature (for coexistence needs), added operations to add/delete methods and fields, added search (character search, method search, field search), improved text editing features, added .dex character constant pool)

Mobile YD has many fun games, but after playing, you realize you really can't play without money. So... this game is really frustrating. Let's target it.

The tools we used are Dalvik bytecode and unpacking tools on the computer, specifics are not introduced here.

1. First find the strings corresponding to purchase failure and purchase success on the computer.

2. Open our installation package with our Dalvik bytecode editor.

3. Search for the strings we found.

5. Replace the content of the onUserOperCancel function with the content of onBillingSuccess. Then enter the mobile game purchase, click not to purchase and exit, and the purchase succeeds.

Same as Xiaohong, as a tech newbie I thank the original poster for sharing
The forum already exists, but I still want to show some support.
Hehe...
