[android-developers] Re: Writing files in UTF-8
Looping?
byte[] bom = {(byte)0xEF, (byte)0xBB, (byte)0xBF };
byte[] byteResult =
Charset.forName("UTF-8").encode(result.toString()).array();
fos = new FileOutputStream(file);
fos.write(bom);
fos.write(byteResult);
Doesn't this work?

You are using put(). Those three statements will overwrite the first three bytes. Isn't there an insert() ? If not: just first write the bom and then the bytes. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

That is not the bom for utf-8. You wrote the bom for UTF-16.
http://en.wikipedia.org/wiki/Byte_order_mark
The bom for utf-8 is 0xEF, 0xBB, 0xBF.

Those attachment have no bom and do not contain characters like
€å”€å”€å”€à €à €à €ç¼€ç¼€ç¼€ç¼€ç¼€ç¼€ç¼€Ì€Ì€Ì€Ì€Ì€Ì€
but a lot of questionmarks line.
?
You are not done before it works with the right bom.

Just a thougth: does the produced file have a BOM (Byte Order Mark) as the first bytes?

All this encoding is very interesting and I would like to help you.

[android-developers] Re: HTTP POST to Web Server running on Android Device
> line=POST / HTTP/1.1
> line=Content-Length: 23
No you would see:
line=POST / HTTP/1.1
line=Content-Length: 23
line=0
if a null was returned.
But a null is never returned. Still your
loop ends as instead an exception is trown.
You did not see that because the catch does nothing.
Add a Log.i there and you will see.
You modified the original code which checked for an empty line.
Take the original code again.
Add a check for the Content-Lengh: line and decode the contentlength.
(in your example 23)
Then outside the loop do something like:
[code]
if ( contentlength > 0 ){
char [] buffer = new char[contentlength];
int nread = in.read (buffer, 0, contentlength);
String Parameters = new String( buffer);
// well you should check nread == contentlength
}
[/code]
> I am wondering where the HTTP POST data is?
That just follows the empty line. But as that data is not ended with
a newline in.readLine() cannot be used.
