Action SEARCH doesn't start new Activity

I have two classes in two different files, one is MainActivity and the other one is SearchResultsActivity.
For some reason when i press the search button it doesn't start SearchResultsActivity, I'm assuming this because i put several breakpoints (even some at the beginning of the class) and the debugger doesn't seem to reach them.
MainActivity.Java
package myapp.myapp;
public class MainActivity extends ActionBarActivity {
private Toolbar toolbar;
ProgressBar theProgressBar;
TextView stInstTxt;
public void sendMessage(View view) {
Intent intent = new Intent(this, MainActivity.class);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.search_element).getActionView();
// Assumes current activity is the searchable activity
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
return true;
}
#Override
public boolean onOptionsItemSelected (MenuItem item){
// Handle item selection
switch (item.getItemId()) {
case R.id.search_element:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//text view
stInstTxt = (TextView) findViewById(R.id.textView01);
//progress bar
theProgressBar = (ProgressBar) findViewById(R.id.progressBar01);
theProgressBar.setVisibility(View.INVISIBLE);
//toolbar
toolbar = (Toolbar) findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
}
}
SearchResultsActivity.Java
package myapp.myapp;
public class SearchResultsActivity extends Activity{
TextView stInstTxt;
Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = getApplicationContext();
handleIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
searchItems(query);
}
}
public void searchItems(String query) {
stInstTxt.append(query);
}
}

Could there be something wrong with AndroidManifest.xml?

After almost 6 hours of trying to implement this (starting with the android documentation as a guide), and trying dozens of different ways to do it, i feel i maybe could help someone else with a similar problem save some time, I came up to this tutorial
I read it all but what I ended up doing was downloading the code and comparing it with mine until i found that I was missing a couple of important things. The official android documentation is incomplete, and pretty much there was no way i could have came up with a solution without seeing a real and complete working example.

Libgdx. when i exit my game admob is still working

i have problem with admob. Admob is working good but when i exit my game admob is still working. What i done wrong ? Please help me.
Even if i exit the game, in the logcat i see that admob is still working.
AndroidLuncher.java
public class AndroidLauncher extends AndroidApplication {
private AdView adView;
private static final String AD_UNIT_ID = "xxxxxxxxxxxxxxxxxxxxxxx";
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
cfg.useWakelock = true;
cfg.useAccelerometer = false;
cfg.useCompass = false;
// Create the layout
RelativeLayout layout = new RelativeLayout(this);
// Do the stuff that initialize() would do for you
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
// Create the libgdx View
View gameView = initializeForView(new MyGameStart(), cfg);
// Add the libGDX view
layout.addView(gameView);
// Create and setup the AdMob view
AdView adView = new AdView(this);
adView.setAdSize(AdSize.SMART_BANNER);
adView.setAdUnitId(AD_UNIT_ID);
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
.build();
// Add the AdMob view
RelativeLayout.LayoutParams adParams =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
adParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
adParams.addRule(RelativeLayout.CENTER_IN_PARENT);
adView.loadAd(adRequest);
layout.addView(adView, adParams);
// Hook it all up
setContentView(layout);
}
#Override
public void onResume() {
super.onResume();
if (adView != null) {
adView.resume();
}
}
#Override
public void onPause() {
if (adView != null) {
adView.pause();
}
super.onPause();
}
#Override
public void onDestroy() {
// Destroy the AdView.
if (adView != null) {
adView.destroy();
}
super.onDestroy();
} }

Create an onStop() method and stop adMob there as well.

Try setting the AdView instance to NULL and leave it there for the GC to handle it. It probably will trow a NullPointerException so make sure you handle that.

I solved the problem.
I had two times Adview adview;
public class AndroidLauncher extends AndroidApplication {
private AdView adView;
#Override
protected void onCreate (Bundle savedInstanceState) {
***
// Create and setup the AdMob view
AdView adView = new AdView(this);
***
When I removed one, AdMob is working correctly.

Can not see add from admob hello world android program

This is my main class -

public class MainActivity extends ActionBarActivity {

setContentView(R.layout.activity_main);
AdView adview = (AdView) this.findViewById(R.id.adView);
AdRequest adrequest = new AdRequest.Builder().build();
adview.loadAd(adrequest);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);

I have added google-play-services_lib properly in my project buildpath.
Project in eclipse shows no error as such. But It is not showing ad after running app.
Internet connection is proper (Checked by running browser on android emulator)
Can someone suggest what might have gone wrong ?
I am new to admob. I have created ad unit default setting and using its id. Is there anything else to be done ??
update - when I removed these two lines
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
It showed error in box where ad is supposed to be placed. That means view has been created ??

Enabled logcat from here -
How to enable LogCat/Console in Eclipse for Android?
Solved problem using this -
Not enough space to show ad (AdMob)
Thanks #William !!!

i have wrote SDL game and ported it to andorid

if i comment this line i can see the ad but not the game ! :
setContentView(mLayout);
So how i can show the ad from starting my game until it exit ?

ADMOB - Unable to start activity ComponentInfo: java.lang.NullPointerException

I did everything like the tutorial tells the AdMob site, put the layout in XML, imported the path Google Play Sevices and added the lines of code from the tutorial, my application compiles, but no longer opens on your smartphone.
Follows the code.

Try changing:
AdView adView = (AdView)this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
To:
AdView adView = (AdView)this.findViewById(R.id.adView);
adView.loadAd(new AdRequest());
