How to save text in a text file and send it as attachment over email in Android? -

when users want email me, want add option can send me logs app. save text in text file , send text file attachment email user going send me.

i have tried following 2 approaches.

approach #1:

calling 2 functions below follows:

            copyfiletoexternal("test_file_name" + ".xml");             sendemail("nilashis@gmail.com", "test_file_name"); 

below functions:

private  file copyfiletoexternal(string filename) {     file file = null;     string newpath = environment.getexternalstoragedirectory()+"/foldername/";     try {         file f = new file(newpath);         f.mkdirs();         fileinputstream fin = openfileinput(filename);         fileoutputstream fos = new fileoutputstream(newpath + filename);         //byte[] buffer = new byte[1024];         byte[] buffer = "safdsdfsdfsdfsdfdsf".getbytes();         int len1 = 0;         while ((len1 = fin.read(buffer)) != -1) {             fos.write(buffer, 0, len1);         }         fin.close();         fos.close();         file = new file(newpath + filename);         if (file.exists())             return file;     } catch (exception e) {      }     return null; }  //method email private void sendemail(string email, string filename) {      file file = new file(environment.getexternalstoragestate()+"/foldername/" + filename+ ".xml");     uri path = uri.fromfile(file);     intent intent = new intent(android.content.intent.action_send);     intent.settype("application/octet-stream");     intent.putextra(android.content.intent.extra_subject, "this subject want");     string to[] = { email };     intent.putextra(intent.extra_email, to);     intent.putextra(intent.extra_text, "here message want");     intent.putextra(intent.extra_stream, path);     startactivityforresult(intent.createchooser(intent, "send mail..."),             1222); } 

approach #2:

does not work:

public void dosendfile() {     string xmlfilename = "filetosend.txt";     fileoutputstream fos = null;     try {         fos = openfileoutput(xmlfilename, mode_world_readable);      } catch (filenotfoundexception e) {         e.printstacktrace();     }     try {         fos.write("this test being written ".getbytes());     } catch (ioexception e) {         e.printstacktrace();     }     try {         fos.close();     } catch (ioexception e) {         e.printstacktrace();     }     intent intent = new intent(android.content.intent.action_send);     intent.settype("text/plain");  //        uri uri = uri.fromfile(new file(xmlfilename));     uri uri = uri.fromfile(new file("/mnt/sdcard/../.."+getfilesdir()+"/"+xmlfilename));     intent.putextra(android.content.intent.extra_stream, uri);     startactivity(intent.createchooser(intent, "send email..asdasd"));  } 

i think can here. sending email in android using javamail api without using default/built-in app

and add in manifest.
