[android-developers] Re: How to send a photo over Bluetooth

Hi,

Thank you, it seems that is exactly what I wanted. I have not tested
it but apparently it works. By the way, I saw there is not an specific
function defined by the FileInputStream class to know the number of
bytes of the picture; do you know how can I get this value. I mean, I
am using this code:

FileInputStream f;
byte[] message_byte_array = new byte[512];

Log.d(TAG, "Sending photo");

try {
f = new FileInputStream("/sdcard/DCIM/Camera/prueba.jpg");
int i = f.read(message_byte_array);

....

f.close();
}

Read returns the number of bytes read, but there is any way to know
this number before to create the byte[] array accordingly??

Once again thanks for your time, Gorka.
