To post xml file to a php server :

public class MainActivity extends AppCompatActivity {

/**
 * Send xml file to server via asynchttpclient lib
 */

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:
