[android-developers] Re: How to release Drawable object from memory ?

2009-11-28 Thread Syl 
I try this solution but it did not work anymore, even if I do
System.gc() to call the garbage collector after setting to null the
variable (calling this method does not guarantee that the garbage
collector will actually be run).

However, I manage to solve my problem resizing the image.

First I get the image size using :
BitmapFactory.decodeStream(InputStream is, Rect outPadding,
BitmapFactory.Options opts)
and setting opts.inJustDecodeBounds to true (to save memory).
Image size is then got with opts.outHeight and opts.outWidth.

Then, I calculate and set opts.inSampleSize value judging from the
maximum image size I want.

Finally, I call again BitmapFactory.decodeStream(InputStream is, Rect
outPadding, BitmapFactory.Options opts) and get the resized image.
