Hi everyone, first time poster.
I'm hit a little snag with the first app I've built.
It's just the tutorial app off the Android Developer's page.
I'd post the link but it won't let me.

Here's my problem, I wrote the code out with 2 activities all linked together and such so that there is no error in Eclipse.
I'm debugging onto my Motorola Droid 2 and after I click the "Send" button it does not go to the next activity.
I've checked my code and all seems good, Perhaps there is something that I missed that you all might be able to clear up for me.
Thank you for reading and I look forward to your responses

This is my "DisplayMessageActivity.java" code where I believe the problem may lie, although unbeknownst to me.
1package com.example.myfirstapp;
2
3import android.annotation.SuppressLint;
4import android.annotation.TargetApi;
5import android.app.Activity;
6import android.content.Intent;
7import android.os.Build;
8import android.os.Bundle;
9import android.support.v4.app.NavUtils;
10import android.view.MenuItem;
11import android.widget.TextView;
12
13public class DisplayMessageActivity extends Activity {
14
15 @SuppressLint("NewApi")
16 @Override
17 protected void onCreate(Bundle savedInstanceState) {
18 super.onCreate(savedInstanceState);
19 setContentView(R.layout.activity_display_message);
20
21 // Get the message from the intent
22 Intent intent = getIntent();
23 String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
24
25 // Create the text view
26 TextView textView = new TextView(this);
27 textView.setTextSize(40);
28 textView.setText(message);
29
30 // Set the text view as the activity layout
31 setContentView(textView);
32
33 // Make sure we're running on Honeycomb or higher to use ActionBar APIs
34 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
35 // Show the Up button in the action bar.
36 getActionBar().setDisplayHomeAsUpEnabled(true);
37 }
38 }
39
40
41 /**
42 * Set up the {@link android.app.ActionBar}, if the API is available.
43 */
44
45 @TargetApi(Build.VERSION_CODES.HONEYCOMB)
46 private void setupActionBar() {
47 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
48 getActionBar().setDisplayHomeAsUpEnabled(true);
49 }
50 }
51
52
53 @Override
54 public boolean onOptionsItemSelected(MenuItem item) {
55 switch (item.getItemId()) {
56 case android.R.id.home:
57 // This ID represents the Home or Up button. In the case of this
58 // activity, the Up button is shown. Use NavUtils to allow users
59 // to navigate up one level in the application structure. For
60 // more details, see the Navigation pattern on Android Design:
61 //
62 //
63 //
64 NavUtils.navigateUpFromSameTask(this);
65 return true;
66 }
67 return super.onOptionsItemSelected(item);
68 }
69
70}
