[android-developers] Re: Error in native method Picture.nativeCreateFromStream()
That method should not crash (I will fix that), but it is only
intended to re-create a picture that was previously written to a
stream. It does not know how to decode or interpreted images or other
data formats. Use BitmapFactory for that.

Hello all,
I'm having some trouble creating a Picture from an InputStream. I am
trying to do this:
ByteArrayInputStream bis = new ByteArrayInputStream(bytes);
Picture pic = Picture.createFromStream(bis);
The problem also occurs when I try to use an InputStream returned by
ContentResolver.openInputStream(Uri):
InputStream is = getContentResolver.openInputStream(mUri);
Picture pic = Picture.createFromStream(is);
Picture.createFromStream(InputStream) invokes the native method
Picture.nativeCreateFromStream(InputStream, byte[]), and this is where
the trail goes cold for me:
public static Picture createFromStream(InputStream stream) {
return new Picture(
nativeCreateFromStream(stream, new byte
[WORKING_STREAM_STORAGE]));
}
I have been loading images from this Uri (content://media/external/
images/media/152) successfully for a while. I open an InputStream,
read all the bytes, close the input stream, and there is no problem.
However, when I try to use either the InputStream returned by
ContentResolver.openInputStream(Uri), or I read all the bytes out of
that and wrap them in a ByteArrayInputStream, Picture.createFromStream
(InputStream) fails with the stack trace below.
Has anyone successfully used Picture.createFromStream(InputStream)?

[android-developers] Re: Error in native method Picture.nativeCreateFromStream()
As you say, it should not crash quite like that, but I see that I was
using it incorrectly now.
BitmapFactory does the job.
Thank you!
