This flips on the x-axis (vertically mirrored)

Using java Syntax Highlighting

 
sprite = BitmapFactory.decodeResource(appContext.getResources(),
 
R.drawable.spritegfx);
 
Matrix aMatrix = new Matrix();
 
aMatrix.preScale(-1.0f, 1.0f); //Line of interest
 
flippedSprite = Bitmap.createBitmap(sprite, 0, 0, sprite.width(),sprite.height(), aMatrix, false);

I'm trying to flip the whole display of my app. Any idea ?

I assume you meant changing the orientation of the app.

Android only has 2 orientations, landscape and portrait. You're not going to get a left facing portrait nor upside-down landscape.
