android activities
<p>i have 2 activities. 
1-Messaging
2-fileBrowser
from MESSAGING onButtonClick i call the FILEBROWSER activity. in the FILEBROWSER activity i take the path of the selected file and put it to a interface and then call the MESSAGING activity again like this : </p>

<pre><code>  Intent i = new Intent(FileBrowser.this, Messaging.class);   
        i.putExtra(FriendInfo.P, path);  
        System.out.println("path at fb" + path);


        startActivity(i);
        this.finish();
</code></pre>

<p>now when i m returned back to the MESSAGING activity everything over here is null. all the variables and everything and if i call some other methods, the arguments i pass are also null. what do i do ?</p>
