Simple Intent to change activity not working

I'm trying to change activity by an intent like this to a fragmentactivity that opens a embeded Google Map:
Intent driver = new Intent(getApplicationContext(), DriverActivity.class);
startActivity(driver);
But the app crashes, I've recently moved from Eclipse on my Windows to a Eclipse on Ubuntu. I can't see why the app won't change activity. The debugger opens layoutInflater.class and the message inside that windows is: Source not found
What's wrong and how do I fix it?

Android: how to refer to EditText view

I have the following layout:
<TextView
android:id = "#+id/HRNoninTextBox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/exitbtn"
android:text="Heart Rate"
android:textSize = "20sp"/>
<EditText
android:id="#+id/labelNoninHeartRate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="00"
android:layout_alignParentRight="true">
</EditText>
from the code i refer to these views, form my activity, in this way:
TextView tvHr= (TextView)findViewById(R.id.HRNoninTextBox);
EditText etHr = (EditText)findViewById(R.id.labelNoninHeartRate);
the first one does not produce any error, while the second statement produce the following error:

Where may be the problem?

Step1 : you can clean/build your project as everyone said . but If you are not getting your issue solve by clean/build then check my step2 for it.
Step:2:
I am not Sure But Can you please check your xml file once again?
this also could be happen if You've two elements with the same ID:
<TextView android:text="Hello Ahmedabad:"
android:id="#+id/txtahmedabad"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<EditText android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:id="#+id/txtahmedabad"
android:text="">
</EditText>
if this is so then Give them different IDs -
it could picking the first one (the TextView) which obviously can't be cast to an EditText.
Hope it will some how help you.

Null Pointer Exception in First Android App

I am trying to write my first Android app, and I'm having trouble. I wrote a simple Java program to find the factors of a number provided by the user, and I'd like to port it over to Java. I have an XML file for the interface, which seemed to run OK until I added the first Java class. Now it won't run, and log.cat says that there's a null pointer exception. So far, I only have stubs, but it seems like it should run OK with what I've done to this point. I'm including the log.cat text, but I'm too new it this to make much sense out of it.
There may be more than one problem. After adding the Java file I began to get run-time errors right away, but I don't think they were null pointer exceptions. I think that started when I made changes to fix what was already causing problems.
Any help is appreciated.
Here is the Java file:
import android.app.Activity; <br>
import android.os.Bundle; <br>
import android.widget.Button; <br>
import android.widget.EditText; <br>
import android.widget.TextView; <br>
public class AndroidFactoringActivity extends Activity {
// Instance Variables
EditText userNumber;
Button factorButton;
TextView resultsField;
int factorResults;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
factorButton = (Button) findViewById(R.id.factorButton);
userNumber = (EditText) findViewById(R.id.userNumber);
factorResults = 1;
resultsField.setText(String.valueOf(factorResults));
}
}
Here is main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/askField"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/ask"
android:textSize="24dp" />
<EditText
android:id="#+id/userNumber"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="number" >
<requestFocus />
</EditText>
<Button
android:id="#+id/factorButton"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/click" />
<TextView
android:id="#+id/resultsField"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tell"
android:textSize="24dp" />
</LinearLayout>
Here are the log.cat results:

resultsField.setText(String.valueOf(factorResults));
resultsField is null and you are trying to set value on null.
resultsField= (TextView ) findViewById(R.id.userNumber);
Get textview instance before setting value, otherwise resultsField will be null and all operations on null reference results in NullPointerException.

You got a null pointer because you didnt intialise the variable resultsField (you just declared it) .
As you used
userNumber = (EditText) findViewById(R.id.userNumber);
you must even initialise the reference resultsField.
This can be done using
resultsField= (TextView ) findViewById(R.id.resultsField);
in the onCreate() after the statement setContentView()

You need to initialize the userNumer and resultsFiled as follows
userNumber = (EditText) findViewById(R.id.userNumber);
resultsField= (TextView ) findViewById(R.id.resultsField);

---EDIT---
Are you sure you have downloaded the "Ad" library and included it in your project? Class not found suggests that you have not successfully linked it to your project. Also try rebuilding your project by following the steps below .
Try cleaning your project... Project > Clean > Choose your Project > Ok
Rerun your project.

it seems that error is caused due to Typos or casting ...... Check carefully for Typos and casting ....... check for library folder name ....

check out this
android:configChanges requieres all parameters to show ads in application
change the SDK version to 14 of your Application
mention it in your AndroidManifest.xml file
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14"/>
<activity android:name="com.google.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
