Android :: Game Goes Blank After Pressing Home And Restarting

I am making an Android game with an Activity called Game, a SurfaceView called GameView and a Thread called GameThread. The Game's onCreate(), I make a new GameView, which makes a new GameThread, where all the game logic and canvas drawing is carried out. However, I'm having some lifecycle difficulties. When I press back and restart it, it works fine, but when I press home and restart it, all I see is a blank screen. Here are the GameView's onSurfaceCreated() and onSurfaceDestroyed(): @Override public void surfaceCreated(SurfaceHolder holder) {
mThread.mRunning = true;
mThread.mWidth = getWidth();
if(mThread.mWidth > 550) mThread.mWidth = 550;
mThread.mHeight = getHeight();
try {
mThread.start();
} catch(IllegalThreadStateException e).......
