Android intent not starting new activity?

I'm trying to do something rather simple here, just launch a new activity from my main one. Here's the code: 

public class mainActivity extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    Intent i = new Intent(mainActivity.this, testActivity.class);  
    startService(i);
}

}

///////////////// next file /////////////////

public class testActivity extends Activity {

@Override 
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test);

    Toast.makeText(this, "testActivity started", Toast.LENGTH_SHORT).show();

}

}

///////////////// manifest section ///////////////////

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".mainActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity android:name=".testActivity" />

But I never see the Toast from testActivity - what gives?

To start an activity you should use startActivity() instead of startService().

You'll also have to make sure the testActivity is listed in your android manifest.

You want to use startActivity instead of startService

Intent i = new Intent(mainActivity.this, testActivity.class);  
startActivity(i);

If the activity is still running in the background, it gets called and only the onResume() gets called, not the onCreate();

check the lifecycle here: http://developer.android.com/guide/topics/fundamentals/activities.html#Lifecycle
