Hi,
I am having difficulties in opening image files for upload with iOS. The
procedure for upload I will explain here is working correctly when deployed
on an Android device.
This is the code I use to open the image file, perform resizing if
necessary and return a byte array for upload:
private byte[] ImageToBinary(String imagePath) throws Exception{
//leemos los archivos en array de bytes
InputStream is =
FileSystemStorage.getInstance().openInputStream(imagePath);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Log.p("InputStream " + is.available(), Log.INFO);
Log.p("path:" + imagePath, Log.INFO);
EncodedImage ei = EncodedImage.create(is, is.available());
int w = ei.getWidth();
int h = ei.getHeight();
Boolean resize = false;
Image scaled = ei;
if (w > 2880)
{
w = 2880;resize = true;
}
if (h > 2160)
{
h = 2160;resize = true;
}
if (resize)
{
scaled = ei.scaled(w, h);
}
ImageIO.getImageIO().save(scaled, baos, ImageIO.FORMAT_JPEG, 0.5f);
return baos.toByteArray();
}
As said this is working in android devices.
As you can see I managed to output basic log information to further explore
what's happening:
The content of the log is as follows:
[null] 0:0:33,647 - Codename One revisions:

...
Can anybody give me any hints on what I might be doing wrong? As you can
see the InputStream.available() method returns 1. The code execution
retries performing this operation up to 10 times before definitively
failing to execute.
Many thanks for any insights.
Carlos Conti.
