Android Smart Car App Modify

Job ID: 39268614

Budget: $30 – $250 USD

I have two versions of an app used in the display of BYD Android smart cars. I want to get the source code of the app and remove the encryption part of BouncyCastle so that it works without asking for the activation code.

Link to both versions: https://mega.nz/fm/kSgEXYgD

The reason for getting it is to use the code inside it (API calling) to create a larger project for my graduation project. (Adding more languages while improving the experience) The owner of the original program is unreachable as he is in Russia.
I have access to the BYD car for testing in the next 10 days.
