how to send post request in android

how to send post request in android
I use async http clint library
I use this methode for get and I need this for post
client.get(getString(R.string.server2) + "culture_types", new TextHttpResponseHandler() {
#Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
}
#Override
public void onSuccess(int statusCode, Header[] headers, String responseString) {
}
}
});

private static AsyncHttpClient client = new AsyncHttpClient();
RequestParams params = new RequestParams();
params.put("param1", "Test"); // Put parameter name
client.post(Url, params, new TextHttpResponseHandler(){
#Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
}
#Override
public void onSuccess(int statusCode, Header[] headers, String responseString) {
}
}
});

GET doesn't enter in methods onSucces and onFailure

I'm trying to do a get with AsyncHttpClient, but doesn't enter in both methods, in Postman it's going well, any idea what could be?
AsyncHttpClient client = new AsyncHttpClient();
String URL = "http://link/link1/link2";
client.get(URL, new AsyncHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
JSONArray dni;
String strResponseBody = new String(responseBody);
try {
dni = new JSONArray(strResponseBody);
for(int i=0; i < dni.length(); i ++){
dniTemporal = dni.getString(i);
Log.d("DNI : ",""+ dniTemporal );
}
} catch (JSONException e) {
Toast.makeText(JourneyDetails.this, "Error", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
Log.d("ERROR STATUS:"," "+ statusCode);
}
});

send data in raw using asynhttpclient

I m posting JSON in raw with this Url [URL I post data to][1]
param is=eventName="countryList"
codes
private void testApp() {
try {
JSONObject jsonParams = new JSONObject();
jsonParams.put("key", "value");
StringEntity entity = new StringEntity(new Gson().toJson(jsonParams));
entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
AsyncHttpClient client = new AsyncHttpClient();
client.post(getApplicationContext(), "url", entity, "application/json", new JsonHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
super.onSuccess(statusCode, headers, response);
Log.e("good",response.toString());
}
#Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
super.onFailure(statusCode, headers, responseString, throwable);
Log.e("fail",throwable.toString());
}
});
} catch (Exception e) {
}
}
error:fail: cz.msebera.android.httpclient.client.HttpResponseException: Internal Server Error

change fromStringEntity entity = new StringEntity(new Gson().toJson(jsonParams));
to:**StringEntity stringEntity = new StringEntity(jsonParams.toString());**
And Also override
#Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
super.onSuccess(statusCode, headers, response);
}
your response return jsonobject not array

GZipped content in http response of GET request using async-http-library for Android

I'm trying to access Google's geocode API using Android-Async-http library in my app. Here is my request and below is response:
���������������UMo�0��WX>Ӫ i{���UJ�$�J�
mߔ%�===�������B��R��}���#�4�.�d�{��$�b��D��V<��<�����w*y�q���y5����o� �����
Here is success callback method of AsyncHttpResponseHandler.
#Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
if (statusCode == HttpStatus.SC_OK) {
try {
String response = new String(responseBody);
//String response = new String(responseBody, "UTF-8"); //this is also giving junk reponse
Log.v("SUCCESS RESPONSE", response);
networkCallback.onSuccess(response);
}catch (Exception e){
e.printStackTrace();
}
}
}
Why am i getting the response as junk? How do I get proper response?

Try this :
#Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
super.onSuccess(statusCode, headers, response);
MyLog.log(TAG, response.toString());
// if is Jsonobjec
}
#Override
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
super.onSuccess(statusCode, headers, response);
MyLog.log(TAG, response.toString());
// if is JsonArray
}
Or you want get response string:
#Override
public void onSuccess(int statusCode, Header[] headers, String responseString) {
super.onSuccess(statusCode, headers, responseString);
}

Used
compile 'com.loopj.android:android-async-http:1.4.9'
instead of 1.4.5

android - GET-request with Loopj

I need to make GET-request to a url consisting JSON-data and try to use Loopj library, but it returnes nothing. I tried to find examples on the Internet but they turned out, maybe, to be obsolete (onSuccess method had different parameters). I tried to adapt my code to that example and what I got:
String AllData=""; AsyncHttpClient client = new AsyncHttpClient();
client.get("wantedUrl", new AsyncHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
for (byte aResponseBody : responseBody) {
AllData += aResponseBody;
}
}
#Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
Toast.makeText(getApplicationContext(),"We got an error",Toast.LENGTH_SHORT).show();
}
});
"wantedUrl" is the url with json, but "AllData" remains empty. How to fix it?

You're getting AsyncHttpResponseHandler callback where you're in need of JsonHttpResponseHandler. Use below code to get the things right on track.
String AllData=""; AsyncHttpClient client = new AsyncHttpClient();
client.get("wantedUrl", new JsonHttpResponseHandler(){
#Override
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
super.onSuccess(statusCode, headers, response);
//Here response will be received in form of JSONArray
}
#Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
super.onSuccess(statusCode, headers, response);
//Here response will be received in form of JSONObject
}
#Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
super.onFailure(statusCode, headers, responseString, throwable);
Toast.makeText(getApplicationContext(), "We got an error", Toast.LENGTH_SHORT).show();
}
});
