If it's any help, I use this method:
public static Bitmap loadResizedBitmap( String filename, int width,
int height, boolean exact ) {
Bitmap bitmap = null;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile( filename, options );
if ( options.outHeight > 0 && options.outWidth > 0 ) {
options.inJustDecodeBounds = false;
options.inSampleSize = 2;
while ( options.outWidth / options.inSampleSize > width
&& options.outHeight / options.inSampleSize >
height ) {
options.inSampleSize++;
}
options.inSampleSize--;
options.inPreferredConfig = Bitmap.Config.RGB_565;
bitmap = BitmapFactory.decodeFile( filename, options );
if ( bitmap != null && exact ) {
Bitmap oldBitmap = bitmap;
bitmap = Bitmap.createScaledBitmap( bitmap, width,
height, false );
oldBitmap.recycle();
}
}
return bitmap;
}
It sets the "inSampleSize" so the resampled image is just bigger than
the given size, then, if exact size is desired, rescales it to exactly
the given dimensions. It also uses RGB 565 to save some memory, you
might want to remove that if you need true color (given the device
supports it...) or alpha channel.
However, even with this method, I sometimes get reports with
OutOfMemoryError. But my app also uses a MediaPlayer instance, which
is quite a memory hog, and allows wallpaper backgrounds, which must be
loaded locally 1.x devices (2.x allows Theme.Wallpaper, which solves
that problem)...
