Android SearchView does not work

Question

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>

searchable.xml

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:hint="Search Queue"
    android:label="@string/app_name" />

For AndroidX searchview proguard you have to use:

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