If you keep text in resources, you should use \n for line breaks. Example from my app:
<string name="about_text">HexWalk is a hex grid version of well known puzzle
game NetWalk. In Netwalk type games, you are a network administrator,
and someone has scrambled your network. Your job is to rotate all the
pieces so that every computer is connected to the server by pipes and
there are no lose ends in your network.
\nNontouch controls:
\ncursor movement - dpad, wasd
\nturn hex clockwise - dpad center, enter
\nturn hex counterclockwise - space
\nzoom - volume up/down, +/-</string>
