Can't display my custom suggestion using SearchView

I'm using a SearchView and I have added the search feature (that works) and now I'm trying to add a custom suggestion. The provider is created but when i type something query() is never called for some reasons.
Where am I wrong?
Here my manifest:

Can you please try to change to this
android:searchSuggestAuthority="com.chefme.chefme.RecipeIngredientTabs.SuggestionProvider
to
android:searchSuggestAuthority="#string/application_package_name"
android:searchSuggestSelection=" ?"
Also you are missing meta-data tag
<meta-data
android:name="android.app.default_searchable"
android:value="com.chefme.chefme.RecipeIngredientTabs.YOURSEARCHACTIVITY" >
</meta-data>

how do i make an android application that run at the background?

I have an the following android application that prints the copied text by the user...
MainActivity.java
package com.example.backgroundrunning;
import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.ClipboardManager;
import android.content.Intent;
import android.view.Menu;
import android.widget.EditText;

#SuppressLint("NewApi")
public class MainActivity extends Activity implements ClipboardManager.OnPrimaryClipChangedListener{
ClipboardManager clipBoard;
TextView tv;
EditText edit;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv=(TextView)findViewById(R.id.note);
edit=(EditText)findViewById(R.id.edit);
clipBoard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
clipBoard.addPrimaryClipChangedListener( this );
startService(new Intent(this,ExampleService.class));
}
#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 void onPrimaryClipChanged() {
ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
String test=clipboard.getText().toString();
tv.setText(test);
}
}
ExampleService.java
package com.example.backgroundrunning;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
public class ExampleService extends Service {
#Override
public void onCreate() {
// The service is being created
}
public int onStartCommand(Intent intent, int flags, int startId) {

// We want this service to continue running until it is explicitly
// stopped, so return sticky.
return START_STICKY;
}
#Override

// after onUnbind() has already been called

// The service is no longer used and is being destroyed

}
i want to make my program that run at the background silently,
means it doesn't close when the user presses back button
I found this code and added that to my program just like the above code,
But it doesn't work...
What is the problem?
And here is my manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

#Override
public void onBackPressed()
{
Intent i= new Intent(Intent.ACTION_MAIN);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addCategory(Intent.CATEGORY_HOME);
startActivity(i);
or
Intent i= new Intent(Intent.ACTION_ALL_APPS);
startActivity(i);
}

Activity not launching even after I add it in AndroidManifest file

I'm new to Android. I read similar posts but I cannot solve my problem.
I added all my activities in androidManifest file, but I cannot move from Second Activity to ThirdActivity using Intent.
Here is MainActivity.java

}

Search activity won't launch?

I have implemented a search system in my app, and the search bar appears, but when enter is pressed the search activity doesn't load.
As well as this, the text typed into the search box is black. The action bar is also black, so is there a way to make it white on API 14+?

I don't receive a force close - it just doesn't launch the search activity.
Also, what permission should I set for the final provider? The android system must be able to execute it,
