I have no direct experience with playing KotOR on Android but there is a guide here:
Said that, if you attempt this, I'd recommend that you use the K1 Community Patch, which is not compatible with K1 Restoration. The first one is the most essential piece of modding any KotOR player should aim to install. The latter has many good things but it's no longer maintained and there are several bugs. @N-DReW25 is working on a smaller-scope restoration project which will probably see a non-beta release sometimes this year.
