Email client not working properly on device?

i have made an application in which i first attach a file into my email and then st开发者_JS百科art an intent to send email which i believe would be the default email client on the phone.

I have tested this application my HTC- Desire phone with android 2.1 and the attachment is properly being attached to the mail and the mail is being sent successfully.

But on another device which is Samsung galaxy s gt-19000, it is giving an error that attachment is too large.

The size of my attachment would not be exceeding 1 MB. what is going wrong over here?

thank you in advance.

Are the phones using the native mail applications? If yes, then I would guess that these have been programmed with a max size for attachments, which is something that you cannot change. Try attaching the attachment through in the email-client, and see if that works or not.
