Rapid debugger: Could this be used to protect apps?

[KMatle]

I wondered how the rapid debugger is able to hot swap code without reinstalling an app. Erel explained it here: https://www.b4x.com/android/forum/threads/rapid-debugger.33120/#content

There's some sort of a shell running on the device. Couldn't that technique be used to protect an app?

- download parts from a server
- execute in that shell
- etc.

However: Jus an idea (without the knowledge how it really works)

It is quite complicated. The device app acts as a virtual machine that accepts commands from the connected PC. The logic is actually implemented on the PC side (there are two pipelines, one on the device and one on the pc. Hot code swap happens on the PC).

I don't see how it can help with app protection.
