Ok, I have looked at multiple examples and my code seems to be correct, but for what ever reason the parameters are not being added to the URL. I'm trying to connect to the Last.Fm API and my code is as follows:
searchIT.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
// TODO Auto-generated method stub
//Create new HTTPClient and Post header
HttpPost API_ROOT = new HttpPost("http://ws.audioscrobbler.com/2.0/");
HttpClient httpclient = new DefaultHttpClient();
try
{
//Add Data
List<NameValuePair> nameValPairs = new ArrayList<NameValuePair>(4);
nameValPairs.add(new BasicNameValuePair("method", "artist.getevents")); //Get events for artist
nameValPairs.add(new BasicNameValuePair("artist", namesBox.getText().toString())); //Get artist name
nameValPairs.add(new BasicNameValuePair("autocorrect", "1")); //Turn on AutoCorrect
nameValPairs.add(new BasicNameValuePair("api_key", "xxxxxxxxxxxxxxxxxxxx")); //API Key - redacted for privacy
API_ROOT.setEntity(new UrlEncodedFormEntity(nameValPairs));
Log.i(TAG, "URL: " + API_ROOT.getURI().toString());
//Execute HTTP Post Request
HttpResponse response = httpclient.execute(API_ROOT);
}
catch (UnsupportedEncodingException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
Am I just missing something here? In the log the url is shown as: http://ws.audioscrobbler.com/2.0/ so it seems to missing all the parameters I was trying to pass into it. Any ideas, tips, corrections or suggestions? Thanks!
From your onClick method start a new activity and pass all the parameters you want to as
HashMap<String, String> o = (HashMap<String, String>) searchList.getItemAtPosition(position);
Intent i = new Intent(SearchActivity.this, SearchDetails.class);
i.putExtra("method", o.get("method"));
i.putExtra("artist", o.get("artist"));
i.putExtra("autocorrect", o.get("autocorrect"));
i.putExtra("api_key", o.get("api_key"));
Then in your new activity: In the onCreate method
Intent myIntent = getIntent();
String method= myIntent.getStringExtra("method");
String artist= myIntent.getStringExtra("artist");
String autocorrect= myIntent.getStringExtra("autocorrect");
String api_key= myIntent.getStringExtra("api_key");
Now you'll get the params as you require and add them to your URL.
Hope it works

Here am using a button to show a gps from one loaction to another...
I am having a problem {Uri.parse("http://maps.google.com/maps?saddr=10.0515097,76.4888416&daddr="+obj.latitude,+obj.longitude));}
while using this...
I am using a web service so latitude and longitude is saved as objects...
I got the gps location without a coma in google map between
+obj.latitude+obj.longitude{Uri.parse("http://maps.google.com/maps?saddr=10.0515097,76.4888416&daddr="+obj.latitude+obj.longitude));}
What should I do to add the comma in between them to track it
Button btn_driver = (Button) v.findViewById(R.id.btn_drivermap);
btn_driver.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.d("SECOND", "doInBackground()");
HttpEntity resEntity;
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(Utils.WebserviceUrl + "get_drivers.php?");
MultipartEntity reqEntity = new MultipartEntity();
try {
reqEntity.addPart("user_id", new StringBody(Utils.user_id));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
reqEntity.addPart("latitude", new StringBody(String.valueOf(Utils.geo_latitude)));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
reqEntity.addPart("longitude", new StringBody(String.valueOf(Utils.geo_longitude)));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=10.0515097,76.4888416&daddr="+obj.latitude,+obj.longitude));
startActivity(intent);
}});
Just added a plus(+) to it
Uri.parse("http://maps.google.com/maps?saddr=10.0515097,76.4888416&daddr="+obj.latitude+","+obj.longitude));
I'm trying to add an event in google places and the JSON returned has an invalid request in status and this endpoint has been removed in error_message. This morning it has worked correctly but now it doesn't work anymore.
I tried to use HTTP in the request to see if it returns the request denied but this doesn't do it, it always returns invalid request.
Here is my code:
private final String EVENT_URL =
"https://maps.googleapis.com/maps/api/place/event/add/json?";
private JSONObject uploadEvent() {
JSONObject jsonobj = new JSONObject();
StringEntity sEntity = null;
try {
jsonobj.put("duration", duration);
jsonobj.put("reference", reference);
jsonobj.put("summary", description);
if(url.length() > 0){
jsonobj.put("url", url);
}
sEntity = new StringEntity(jsonobj.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppostreq = new HttpPost(getUrlEvent());
httppostreq.setEntity(sEntity);
String responseText;
JSONObject JSON = null;
try {
HttpResponse httpresponse = httpclient.execute(httppostreq);
responseText = EntityUtils.toString(httpresponse.getEntity());
JSON = new JSONObject(responseText);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return json;
}
private String getUrlEvent(){
//genero la solicitud como la debajo descrita
StringBuilder urlString = new StringBuilder(EVENT_URL);
urlString.append("&sensor=false&key=" + API_KEY);
return urlString.toString();
}
Can anyone helps me please?
Try
sEntity.setContentEncoding("UTF-8");
sEntity.setContentType("application/json");
httppostreq.addHeader("Content-Type", "application/json");
To quote the documentation:
Note: Events and place bumps were deprecated on September 3, 2014. The deprecation period has now ended. As of February 10th, 2015, the
API no longer accepts event or bump actions, and no longer returns
events in Place Search or Place Details responses.
The code isn't working. Please help. The item gets added to the database except for the quantity. It's always zero. Why is that?
String value;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.creamy);
EditText et = (EditText) findViewById(R.id.CreamyEdit);
value = et.getText().toString();
Button b = (Button) findViewById(R.id.buttonCreamy);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(Creamy.this, "Item Submitted", Toast.LENGTH_LONG).show();
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(
"http://10.0.2.2:8080/http/test.php");
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("item", "Creamy Delight")); //reflected in db
pairs.add(new BasicNameValuePair("quantity", value)); //not reflected in db
try {
post.setEntity(new UrlEncodedFormEntity(pairs));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
HttpResponse response = client.execute(post);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
}
});
Help please!
Move the line value = et.getText().toString(); into the onClick method. If you call et.getText in onCreate it always returns an empty string, because that's all that's inside the EditText at the time of onCreate.
I'm trying to use HttpClient to connect to a php page that logs in and passes back a sessionid and then goes to a new page, using that sessionid and obtains a mySQL datafield associated with that sessionid.
On the first request, HttpClient can take 1.5 seconds, 6 seconds, or 2 minutes. If the first request was slow, subsequence requests seem to be faster, and visaversa.
The HttpClient request occurs when a Button view is clicked

Before I set Http version 1.1 it took double the time, but for my application, the speed cannot be unreliable. This is all on a pretty fast WiFi connections -- can you image Edge or 3G speeds??
So what can I optimize?
Thanks everyone:)
EDIT: I did a new test with: http://www.posttestserver.com/ and it happened pretty fast. The urls I'm using currently aren't my final server urls, they are for a different site on a different server -- shared hosting, so could it be that contacting my shared hosting site is just slow and will be compared to my .net server?
Thanks again !
i want to run the script behind the button of Google search that means...posting a form to google server and getting the response in the form of html string and finally i put that string on webview to display result....
then i run the code ...
some times it shows correct result (like someone click on google search button) but some times it shows me message to "force to close" without any changes i do in to code....that means prediction about output is unexpected...
My code is like this......
public class url extends Activity

HttpResponse end = null;
String endResult = null;
WebView mWebView;
Intent myWebViewIntent;
public static final int TIMEOUT_MS=10000;

//engine.loadData(endResult, "text/html", "UTF-8");
engine.requestFocus(View.FOCUS_DOWN);
//engine.loadUrl(endResult);
}
}
so is there any problem in emulator or installation of SDk or program itself....? becoz it seems to be the connection with the internet is done but i use the proper permission..
thank you..
The ANR you get is because you're making a blocking call on the UI thread. To perform a blocking action without blocking the UI thread you have to use a thread and a handler, or (recommended) an AsyncTask.
