Source code security is an important part of security in general. Indeed the many attacks are directed to the source code. On the other hand, the source code is the only valued thing you have after a few years of hard work.
It's also clear that all your support, marketing, and customer relations will be rendered useless if your code falls into the hands of a competitor or is stolen by an attacker.
Java developers are familiar with the scenario where a sold jar is recompiled and, with minor changes to circumvent patent or intellectual property protection, appears on the markets and takes away a significant part of the profit.
There are many source code protection tools for Java and Java-based languages. Among them, the most modern and reliable means is byte code level protection. This means that during the protection process, special transformations are carried out with the byte code, after which the original functionality of the recompiled Java app cannot be restored, just as text encrypted, for example, using AES-256 cannot be decrypted, even if there is the source of AES-256 algorithm.

Antidecompiler for Android 3.0

Version 3.0 protects your Android apps aka APK files at the dex-code level.
Today this is the most reliable solution for protecting your intellectual
property from stealing and plagiarism.
Antidecompiler encrypts all dex files included in the source apk and
thus protects them from decompilation. The key used for encryption
is calculated on the fly and can't be extracted from Antidecompiler
code by decompilators or other methods. For each known attack method,
a counter-method is found and implemented. For technical details
see User Guide, How It Works, Apology, and DZone pages.

It requires any OS with Java 17 - 22 and Android API 30 at least.
This version protects up to 95% of Android applications.
Purchasing SerialNo removes Toast from your protected app.
