新SendFileEmail()发送(f.getPath());
I am beginning with android and this is my first program.
This is what my code looks like. I am able to send an email (in background) using this code but unable to attach a file with that as email attachment. I have given permission in mainfest.xml
Please let me know what I am doing wrong and what need to be implemented.
Any help is much appreciated.

call the method like this

public static void main(String[] args) {

}
}
If the file is in asset folder example test.txt

if (!f.exists()) try {

int size = is.available();

is.read(buffer);
is.close();
FileOutputStream fos = new FileOutputStream(f);
fos.write(buffer);
fos.close();
} catch (Exception e) { throw new RuntimeException(e); }
new SendFileEmail().send(f.getPath());
