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?

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>

What would be the proper way to Implement a Google Search with SearchView. For example, I press the Search button, and enter a query, and then after I hit enter button, it would do a google search in which I can get JSON data. All the examples I've seen are with lists or something similar. I'm trying figure out how to implement a Web search into SearchView
try using Google Custom Search api
I know this is old, but you should not put your SearchView searchView as a global variable, as that can lead to memory leaks. Instead, keep it as a local variable inside of onCreateOptionsMenu.
Figured it out! It was probably something to do with my Android Manifest or something:

I am trying to read some information via NFC and created the intent-filter to do so, together with the xml that contains the required technologies. The intent-filter should start my ReadActivity, but it doesn't do so, when I put the card near my phone. NFC is activated, so this shouldn't be the problem. I really don't see the problem with my code, so it would be great if someone could take a look at it and maybe give me a hint in the right direction. Here is the code:

The AboutActivity and SettingsActivity don't contain anything yet, so I didn't include them in this post. I really don't know where the problem is though.
Restarting my phone and the NFC-setting solved the problem.
I want to make a search with suggestions.
after running the app and typing a string in my search box non of the following Logs Log.d("states","a onCreate"), Log.d("states",arg0.toString()), Log.d("states",query) or Log.d("states","searchactivity onCreate") execute.
What do I have to do do so the query() method in a.java or the onCreate() method in b.java are called?
Please dont send me to google developer documents its very confusing.

I think in your a-class you have to implement the getType()-method:
private UriMatcher uriMatcher;
#Override
public boolean onCreate() {
final String authority = "com.example.searchapp.searchsuggestion";
uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY, SEARCH_SUGGEST);
uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY + "/*", SEARCH_SUGGEST);
return true;
}
#Override
public String getType(Uri uri) {
switch (uriMatcher.match(uri)) {
case SEARCH_SUGGEST:
return SearchManager.SUGGEST_MIME_TYPE;
default:
throw new IllegalArgumentException("Unknown URL " + uri);
}
}
When I launch a new activity I get this force close error:

try extending ActionBarActivity.it extends to fragment activity itself.So you do not need to worry about fragment activity.
Hope it will help.
As i can see you have not pass the drawer item list to NavDrawerListAdapter.
so where are you setting your drawer items?
I am trying to implement the search widget in android but unsuccessful. It lets me type the query text in the seacrh textbox but nothing happens when I press Enter. I followed the tutorial very closely http://developer.android.com/training/search/setup.html. But I can't fix the problem. I've been trying everything for 6 hours now. Please help!
