Call this method in onDestroy of your main activity.

 public void SendLogcatMail(){

    // save logcat in file
    File outputFile = new File(Environment.getExternalStorageDirectory(),
            "logcat.txt");
    try {
        Runtime.getRuntime().exec(
                "logcat -f " + outputFile.getAbsolutePath());
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

 //send file using email
 Intent emailIntent = new Intent(Intent.ACTION_SEND);
 // Set type to "email"
 emailIntent.setType("vnd.android.cursor.dir/email");
 String to[] = {"yourmail@gmail.com"};
 emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
 // the attachment
 emailIntent .putExtra(Intent.EXTRA_STREAM, outputFile.getAbsolutePath());
 // the mail subject
 emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
 startActivity(Intent.createChooser(emailIntent , "Send email..."));
 }
