I am using
android-async-http
and really liking it. I've run into a problem with POSTing data. I have to post data to the API in the following format: -
<request>
<notes>Test api support</notes>
<hours>3</hours>
<project_id type="integer">3</project_id>
<task_id type="integer">14</task_id>
<spent_at type="date">Tue, 17 Oct 2006</spent_at>
</request>
As per the documentation, I tried doing it using RequestParams, but it is failing. Is this any other way to do it? I can POST equivalent JSON too. Any ideas?
Loopj POST examples - extended from their Twitter example:
private static AsyncHttpClient client = new AsyncHttpClient();
To post normally via RequestParams:
RequestParams params = new RequestParams();
params.put("notes", "Test api support");
client.post(restApiUrl, params, responseHandler);
To post JSON:
JSONObject jsonParams = new JSONObject();
jsonParams.put("notes", "Test api support");
StringEntity entity = new StringEntity(jsonParams.toString());
client.post(context, restApiUrl, entity, "application/json",
responseHandler);

@Timothy answer did not work for me.
I defined the Content-Type of the StringEntity to make it work:
JSONObject jsonParams = new JSONObject();
jsonParams.put("notes", "Test api support");
StringEntity entity = new StringEntity(jsonParams.toString());
entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
client.post(context, restApiUrl, entity, "application/json", responseHandler);
Good Luck :)

RequestParams params = new RequestParams();
params.put("id", propertyID);
params.put("lt", newPoint.latitude);
params.put("lg", newPoint.longitude);
params.setUseJsonStreamer(true);
ScaanRestClient restClient = new ScaanRestClient(getApplicationContext());
restClient.post("/api-builtin/properties/v1.0/edit/location/", params, new AsyncHttpResponseHandler() {

protected void makePost() {
AsyncHttpClient client = new AsyncHttpClient();
Context context = this.getApplicationContext();
String url = URL_String;
String xml = XML-String;
HttpEntity entity;
try {
entity = new StringEntity(xml, "UTF-8");
} catch (IllegalArgumentException e) {
Log.d("HTTP", "StringEntity: IllegalArgumentException");
return;
} catch (UnsupportedEncodingException e) {
Log.d("HTTP", "StringEntity: UnsupportedEncodingException");
return;
String contentType = "string/xml;UTF-8";
Log.d("HTTP", "Post...");
client.post( context, url, entity, contentType, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(String response) {
Log.d("HTTP", "onSuccess: " + response);
... other handlers
If someone have a problem that httpclient send as Content-Type: text/plain, please refer this link: https://stackoverflow.com/a/26425401/361100
The loopj httpclient is somewhat changed (or has problem) which cannot override StringEntity native Content-Type to application/json.

You can add the JSON string as an InputStream of some kind - I've used the ByteArrayStream, then passing it to the RequestParams you should set the correctMimeType
InputStream stream = new ByteArrayInputStream(jsonParams.toString().getBytes(Charset.forName("UTF-8")));
multiPartEntity.put("model", stream, "parameters", Constants.MIME_TYPE_JSON);
Just make JSONObject and then convert it to String "someData" and simply send with "ByteArrayEntity"
private static AsyncHttpClient client = new AsyncHttpClient();
String someData;
ByteArrayEntity be = new ByteArrayEntity(someData.toString().getBytes());
client.post(context, url, be, "application/json", responseHandler);
It is working fine for me.
Button button;
String url = "http://xxx/index.php";
String filePath = Environment.getExternalStorageDirectory()+"/Download/testUpload.xml";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
postFile();
public void postFile(){
Log.i("xml","Sending... ");
RequestParams params = new RequestParams();
try {
params.put("key",new File(filePath));
}catch (FileNotFoundException e){
e.printStackTrace();
AsyncHttpClient client = new AsyncHttpClient();
client.post(url, params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int i, cz.msebera.android.httpclient.Header[] headers, byte[] bytes) {
Log.i("xml","StatusCode : "+i);
@Override
public void onFailure(int i, cz.msebera.android.httpclient.Header[] headers, byte[] bytes, Throwable throwable) {
Log.i("xml","Sending failed");
@Override
public void onProgress(long bytesWritten, long totalSize) {
Log.i("xml","Progress : "+bytesWritten);
After adding android-async-http-1.4.9.jar to android studio,
go to build.gradle and add :
compile 'com.loopj.android:android-async-http:1.4.9' under dependencies
And on AndroidManifest.xml add:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
