Android: getSearchableInfo(getComponentName()) returning null?

I'm trying to get suggestions for SearchView. I've implemented a custom content provider for it. I've also referred to this link to implement suggestions for the SearchView. The problem I'm facing is, I get null value on searchManager.getSearchableInfo(getComponentName())

Here are the snippets:

AndroidManifest.xml

    <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <provider android:name=".SearchProvider"
        android:enabled="true"
        android:authorities="com.example.currentlocationmapdemo"
        android:grantUriPermissions="true"
        android:exported="true">
        <grant-uri-permission android:pathPattern="*" />
    </provider>
    <uses-library android:name="com.google.android.maps" />

    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </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:label="label"
android:hint="hint"
android:searchSuggestAuthority="com.example.currentlocationmapdemo"
android:searchSuggestSelection=" ? ">

MainActivity

    @Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.searchview_in_menu, menu);
    MenuItem searchItem = menu.findItem(R.id.action_search);
    mSearchView = (SearchView) searchItem.getActionView();
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchableInfo info = searchManager.getSearchableInfo(getComponentName());  // null returned
mSearchView.setSearchableInfo(info);

 return true;
}
