Unless you run strongSwan on a rooted device (possibly with a modified
kernel, as some kernels missed required modules) this won't work because
the IKE daemon will not be able to access the kernel's IPsec stack. You
could perhaps try to use the kernel-libipsec backend but you'll still
need root permission to create TUN devices.

I can't reproduce either one of these issues. What codebase did you use?

Theoretically, yes. But due to the limitations mentioned above it's
definitely not the recommended way of building/using it anymore on Android.

How exactly are you building strongSwan?
