we modifid snake from sdk samples. there is a running exception
"stopped unexpectedly". after step debug, i found that the statement
setContentView(R.layout.snake_layout); and mSnakeView.setTextView
((TextView) findViewById(R.id.text));from snake.java file will throw
exceptions. i think the layout xml file have a some error. but i can't
find any error in this file.
