Help! How to Convert and Recompile XAPK Files

[sara7645]

Hi everyone,

I've recently ventured into the world of Android modding and am currently working on modding the game Marvel Contest of Champions. However, I've run into a challenge—every site I visit only offers the game as an XAPK file, not an APK. I downloaded the XAPK from APKPure, installed the unmodded APK on BlueStacks, and it works fine.

but when i decompile and recompile the apk without altering the code i get an error when installing the apk (Application can not be installed)

What I've Tried So Far​

I'm still learning the basics of decompiling and recompiling APKs without altering the code. Here’s a summary of what I’ve attempted, though none of these methods have worked:

• Changing the XAPK Extension: I changed the XAPK extension to .zip, extracted the contents, and then re-archived the files in the same order without making any changes. However, the APK failed to install.
• Using APKEditor Tool and APKTool: I used the APKEditor tool to convert the extracted XAPK into an APK, but the installation failed with a "Certification Verification Failed" error. I then tried signing the APK with APKTool, but the installation still didn’t succeed.
• Converting XAPK to APK with APKTool: I tried converting the XAPK directly to an APK using APKTool, but encountered a "Title Not Found" error.

Thanks

Unfortunately, I'm not going to help you with that as If I do so, I'm disturbing platinmods from earning a bit of money which I'd prefer not to do.

It's still an issue to me. My apologies for this. Even if I do update it and give it to you, I'll need payment.
