I have a PNG image with 86 KB in size and 8 in bit depth. But when i look at the image in the apk (bin folder), it's size changed to 193 KB and 24 in bit depth...

I don't even modify the image in my code.... what happened?

I've had problems loading 8-bit PNG's at runtime using

Code: Select all

BitmapFactory.decodeStream(is);

It only seems to be able to decode 24-bit PNG's.

What the #"¤%£$? Some of my 8-bit png's in /res/drawable have been converted to 24-bit, but the ones with transparency have been converted to 32-bit

Ah well, it seems some hidden part of the .apk generation script is to convert PNG's.

Should be:

Remember the problems I had loading 8-bit PNG's at runtime

i don't think they made our image smaller.....
scary...
