Yes you can use the REST api's in android apps.
I have used the REST apis for google local search. You need to use...
HttpClient object.
For parsing using JSON. Check below how i have did it.
Example:
HttpClient client = new DefaultHttpClient();
String query = "http://ajax.googleapis.com/ajax/services/search/local?
hl=en&v=1.0&q=paris hotel&key="+KEY+"&start=";
query+=count;
try {
URL url = new URL(query);
URI uri = new URI(url.getProtocol(), url.getHost(),
url.getPath(),
url.getQuery(), null);
HttpGet request = new HttpGet(uri);
HttpResponse response = client.execute(request);
result=Userrequest(response);
}catch (URISyntaxException e){
}
catch(Exception ex){
//txtResult.setText("Failed!");
}
public String Userrequest(HttpResponse response){
try{
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new
InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null){
str.append(line + "\n");
}
in.close();
result = str.toString();
updateData(result);
}catch(Exception ex){
result = "Error";
}
return result;
}
public void updateData(String result)
{
try
{
JSONObject json=new JSONObject(result);
JSONArray ja;
json = json.getJSONObject("responseData");
ja = json.getJSONArray("results");
int resultCount = ja.length();
//DATA = new String[resultCount];
//ADDR = new String[resultCount];
for (int i = 0; i < resultCount; i++)
{
JSONObject resultObject = ja.getJSONObject(i);
title.add(resultObject.get("titleNoFormatting").toString());
JSONArray addr;
addr = resultObject.getJSONArray("addressLines");
int count = addr.length();
//ADDR[i]="";
String addrr="";
for(int j=0;j<count;j++)
{
addrr+=addr.getString(j);
if(j==0)
addrr+=',';
}
address.add(addrr);
}
setListAdapter(new EfficientAdapter(this));
}
catch(Exception e)
{
}
}
Thanks,
Mani
