{
int frameBufferHeight = 1000px ;
int frameBufferWidth = 600px ;
}
else
{
int frameBufferHeight = 1000px ;
int frameBufferWidth = 600px ;
}

boolean CheckOrientation(). getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT;

int frameBufferWidth = 600px ;
}
else
{
int frameBufferHeight = 1000px ;
int frameBufferWidth = 600px ;
}

View the section of Android code given below:
public void draw(Canvas canvas) {
Rect destRect = new Rect(getX(), getY(), getX() + spriteWidth, getY() + spriteHeight);
canvas.drawBitmap(bitmap, sourceRect, destRect, null);
canvas.drawBitmap(bitmap, 20, 150, null);
Paint Paint = new Paint();
paint.setARGB(50, 0, 255, 0);
canvas.drawRect(20 + (currentFrame * destRect.width()), 150, 20 + (currentFrame *destRect.width()) +destRect.width(), 150 + destRect.height(), paint);
The code is executed using eclipse. What does the above code do?

It draws an image at two positions. One image is drawn at the coordinates (20, 150) and second at the coordinates (50, 255).

It displays a frame at the coordinates (20, 150) and creates a new paint object so we can paint over the current frame on the original image.

It displays a frame at the coordinates (50, 255) and creates a new paint object so we can paint over the current frame on the original image.

It displays an image at the coordinates (50, 255) using the Paint method.

It draws a rectangle at the coordinates (50, 255) using the Paint method.

if (glyphs.get(ch) != null) {
canvas.drawBitmap(glyphs.get(ch), x + i, (y* width), null); } } }

displayString(Canvas canvas, String text) {
int x;
int y;
for (intx= 0; x < text.length(); x++) {
Character ch
if (glyphs.get(ch) != null) {
canvas.drawBitmap(glyphs.x+ (i* width.y, null); } } }

public void displayString(Canvas canvas, String text, int x, int y){
for (int i = 0; i < text.length(); i++) {
Character Ch = text.CharAt(i);
if (glyphs.get(ch) != null) {
canvas.drawBitmap(glyphs.get(ch), x + (i * width), y, null); } } }
