That's going to be an issue. Android devices are usually RISC/ARM chipsets (like a cell phone), which is a different processor architecture than a PC (which is what Liberte/TAILS are compiled to run on). Though I've never looked into alternative builds that may be out there; you may be able to find one... it's going to be a long involved process though, unless somebody else has already gotten through it & made it easier for you to follow.
