Can you edit this code make the player visible at the bottom of the screen, make the bullets functional, collision functional, and allow the player to move across the bottom of the screen? Also, can you make the background of the drawables clear? This is being done in Android Studio: public class MainActivity extends AppCompatActivity $\{$
