Android SearchView does not work

I tried to update all the libraries, but i still got errors. I am able to run the app on the simulator, but when I export the APK and run it on a real android device, the app is not working.

MinSdkVersion is 8, targetSdkVersion is 19. Please help!!!

menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
        xmlns:example="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_showTC"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="Terms and Conditions"/>

    <item android:id="@+id/action_search"
          android:title="Search"
          android:orderInCategory="100"
          example:showAsAction="ifRoom|collapseActionView"
          example:actionViewClass="android.support.v7.widget.SearchView"/>

</menu>

SearchView 

@Override
public boolean onOptionsItemSelected(MenuItem item){
    if(item.getItemId() == R.id.action_showTC){
        startActivity(new Intent(MainActivity.this, T_C.class));
        return true;
    }else{
        return super.onOptionsItemSelected(item);
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SupportMenuItem searchMenuItem = ((SupportMenuItem) menu.findItem(R.id.action_search));
    SearchView searchView = (SearchView) searchMenuItem.getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

    return super.onCreateOptionsMenu(menu);
}

manifest

    <activity android:name="com.agehk.queue.SearchResultsActivity"
        android:parentActivityName="com.agehk.queue.MainActivity" >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>

        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>

For AndroidX searchview proguard you have to use:

-keep class androidx.appcompat.widget.SearchView { *; }

I had to add this and now it works smooth:

-keep class android.support.v7.widget.SearchView {
   public <init>(android.content.Context);
   public <init>(android.content.Context, android.util.AttributeSet);
}
-keep interface android.support.v7.widget.SearchView {
   public <init>(android.content.Context);
   public <init>(android.content.Context, android.util.AttributeSet);
}

Required minimum to proguard-rules.pro

-keep class android.support.v7.widget.SearchView {
   public <init>(android.content.Context);
   public <init>(android.content.Context, android.util.AttributeSet);
}

After long hours of research a simple solution of this problem i.e just add

-keep class android.support.v7.widget.SearchView { *; }

in app/proguard/android.proguard file of AndroidStudio.

Cheers!

Add following code to proguard-rules.pro

-keep class android.support.v7.widget.SearchView { *; }

I (also) got 

Attempt to invoke virtual method 'void android.support.v7.widget.SearchView.setOnQueryTextListener(android.support.v7.widget.ao)' on a null object reference

when launching my release build (with proguard/minify enabled).

Adding this to the proguard rules fixed it:

-keep class android.support.v7.widget.SearchView { *; }

This will keep the SearchView widget but will still allow proguard to throw away any other support library classes that you're not using, so you keep your release build nice and tidy.

Have you enabled Proguard in your build? If so, you may want to ensure that the appcompat libraries are in the Proguard exclusion list (in proguard.cfg). A brute force approach is to keep all the support library classes with:

   -keep class android.support.v4.app.** { *; }
   -keep interface android.support.v4.app.** { *; }
   -keep class android.support.v7.app.** { *; }
   -keep interface android.support.v7.app.** { *; }

In my case, I had a class that extended the support library's SearchView so I added this to my proguard.cfg:

-keep public class * extends android.support.v7.widget.SearchView {
   public <init>(android.content.Context);
   public <init>(android.content.Context, android.util.AttributeSet);
}

The constructors are specifically mentioned to avoid the error:

java.lang.NoSuchMethodException: <init> [class android.content.Context]

For API before 11 you should initialize Action Bar Items in compatibility mode:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        MenuItem searchMenuItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView)MenuItemCompat.getActionView(searchMenuItem);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        return true;
    }

Update:
 So, I tried to reproduce it in API 8 emulator and on 4.4 KitKat. Unfortunately, my 2.3.8 device got bricked a while ago, so could not check in hardware with low API. What I can suggest you:
1. Check that SearchView is imported from android.support.v7.widget.SearchView;
2. Check menu resource is correct:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto" <----------- init compatible namespace
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity" >

    <item
        android:id="@+id/action_showTC"
        android:orderInCategory="100"
        android:title="@string/terms_and_conditions"
        app:showAsAction="never"/>  <----------- use compatible namespace

    <item android:id="@+id/action_search"
          android:title="@string/search"
          android:orderInCategory="100"  <---------- use different value
          app:showAsAction="ifRoom|collapseActionView"
          app:actionViewClass="android.support.v7.widget.SearchView"/>

</menu>

3. return true from onCreateOptionsMenu if there's no underlying processing (Activity class is not subclassed)

UPDATE2: GOT IT! You probably extends from Activity class. Should be ActioBarActivity:

public class MainActivity extends ActionBarActivity {
...
