Please can someone help me with development of android application which incorporates google search at the background.
I am a newbie and I am trying to design an android application to track crimes in my country automatically. Someone told me to use the google custom search in my application. I have obtained the api key and search engine id but I have no idea how to implement it to get the desired results.
I have been searching all over the internet but to no avail. All they talk about is google maps and others which i can't relate it to my problem.
Any sample code will be gladly appreciated. Thanks

I have some code which I used to search for images also using the google search engine, it should at least give you an idea on what to look for.
this are the main imports I uses
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.customsearch.Customsearch;
import com.google.api.services.customsearch.model.Result;
import com.google.api.services.customsearch.model.Search;
and this is the method that uses the search engine
public List<Result> getSearchResult(String keyword){
// Set up the HTTP transport and JSON factory
HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
//HttpRequestInitializer initializer = (HttpRequestInitializer)new CommonGoogleClientRequestInitializer(API_KEY);
Customsearch customsearch = new Customsearch.Builder(
new NetHttpTransport(),
new JacksonFactory(),
null)
.setApplicationName("RandomImage")
.build();
List<Result> resultList = null;
try {
Customsearch.Cse.List list = customsearch.cse().list(keyword);
list.setKey(API_KEY);
list.setCx(SEARCH_ENGINE_ID);
list.setSafe("off");
list.setSearchType("image");
list.setImgSize("medium");
list.setNum(3L);
Search results = list.execute();
resultList = results.getItems();
}catch (Exception e) {
e.printStackTrace();
}
if (resultList == null) {
return new ArrayList<Result>();
} else {
return resultList;
}
}
I remember the documentation being confusing when I did this, but at least this is what worked for me.
Manifest
