Вам нужен PHP скрипт или что-то для поддержки аудио загрузки (10.0.2.2:8080/audioupload/).

Вот пример взятия кода от here.

private void doFileUpload(){ 
     HttpURLConnection conn = null; 
     DataOutputStream dos = null; 
     DataInputStream inStream = null; 
     String lineEnd = "rn"; 
     String twoHyphens = "--"; 
     String boundary = "*****"; 
     int bytesRead, bytesAvailable, bufferSize; 
     byte[] buffer; 
     int maxBufferSize = 1*1024*1024; 
     String responseFromServer = ""; 
     String urlString = "http://10.0.2.2:8080/audioupload/"; 
     try 
     { 
     //------------------ CLIENT REQUEST 
     FileInputStream fileInputStream = new FileInputStream(new File(path)); 
     // open a URL connection to the Servlet 
     URL url = new URL(urlString); 
     // Open a HTTP connection to the URL 
     conn = (HttpURLConnection) url.openConnection(); 
     // Allow Inputs 
     conn.setDoInput(true); 
     // Allow Outputs 
     conn.setDoOutput(true); 
     // Don't use a cached copy. 
     conn.setUseCaches(false); 
     // Use a post method. 
     conn.setRequestMethod("POST"); 
     conn.setRequestProperty("Connection", "Keep-Alive"); 
     conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); 
     dos = new DataOutputStream(conn.getOutputStream()); 
     dos.writeBytes(twoHyphens + boundary + lineEnd); 
     dos.writeBytes("Content-Disposition: form-data; name="uploadedfile";filename="" + selectedPath + """ + lineEnd); 
     dos.writeBytes(lineEnd); 
     // create a buffer of maximum size 
     bytesAvailable = fileInputStream.available(); 
     bufferSize = Math.min(bytesAvailable, maxBufferSize); 
     buffer = new byte[bufferSize]; 
     // read file and write it into form... 
     bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
     while (bytesRead > 0) 
     { 
      dos.write(buffer, 0, bufferSize); 
      bytesAvailable = fileInputStream.available(); 
      bufferSize = Math.min(bytesAvailable, maxBufferSize); 
      bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
     } 
     // send multipart form data necesssary after file data... 
     dos.writeBytes(lineEnd); 
     dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
     // close streams 
     Log.e("Debug","File is written"); 
     fileInputStream.close(); 
     dos.flush(); 
     dos.close(); 
     } 
     catch (MalformedURLException ex) 
     { 
      Log.e("Debug", "error: " + ex.getMessage(), ex); 
     } 
     catch (IOException ioe) 
     { 
      Log.e("Debug", "error: " + ioe.getMessage(), ioe); 
     } 
     //------------------ read the SERVER RESPONSE 
     try { 
       inStream = new DataInputStream (conn.getInputStream()); 
       String str; 

       while ((str = inStream.readLine()) != null) 
       { 
        Log.e("Debug","Server Response "+str); 
       } 
       inStream.close(); 

     } 
     catch (IOException ioex){ 
      Log.e("Debug", "error: " + ioex.getMessage(), ioex); 
     } 
     } 

Ниже PHP скрипт (вы должны положить его в 10.0.2.2:8080/audioupload/

<?php 
// Where <span class="IL_AD" id="IL_AD9">the file</span> is going to be placed 
$target_path = "uploads/"; 

/* Add the original filename to our target path. 
Result is "uploads/filename.extension" */ 
$target_path = $target_path . basename($_FILES['uploadedfile']['name']); 

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { 
    echo "The file ". basename($_FILES['uploadedfile']['name']). 
    " has been uploaded"; 
} else{ 
    echo "There was an error uploading the file, please try again!"; 
    echo "filename: " . basename($_FILES['uploadedfile']['name']); 
    echo "target_path: " .$target_path; 
} 
?> 

Как хорошая практика, вы должны использовать AsyncTask, AsyncHttpClient загрузить аудио. коды, приведенные выше, являются только примерами;)

Answer 2

Попробуйте этот код, это отлично работает с использованием async http client. Для сценария на стороне сервера используйте код, упомянутый выше. Спасибо

public class AudioActivity extends ActionBarActivity { 

    private static final int SELECT_AUDIO = 2; 
    String selectedPath = ""; 
    ProgressDialog prgDialog; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_audio); 

     openGalleryAudio(); 

     prgDialog = new ProgressDialog(this); 
     prgDialog.setCancelable(false); 

    } 

    public void openGalleryAudio(){ 

     Intent intent = new Intent(); 
     intent.setType("audio/*"); 
     intent.setAction(Intent.ACTION_GET_CONTENT); 
     startActivityForResult(Intent.createChooser(intent,"Select Audio "), SELECT_AUDIO); 
    } 

    public void onActivityResult(int requestCode, int resultCode, Intent data) { 

     if (resultCode == RESULT_OK) { 

      if (requestCode == SELECT_AUDIO) 
      { 
       System.out.println("SELECT_AUDIO"); 
       Uri selectedImageUri = data.getData(); 
       selectedPath = getPath(selectedImageUri); 
       System.out.println("SELECT_AUDIO Path : " + selectedPath); 
       doFileUpload(); 

       prgDialog.setMessage("Calling Upload"); 
       prgDialog.show(); 
      } 

     } 
    } 

    public String getPath(Uri uri) { 
     String[] projection = { MediaStore.Images.Media.DATA }; 
     Cursor cursor = managedQuery(uri, projection, null, null, null); 
     int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
     cursor.moveToFirst(); 
     return cursor.getString(column_index); 
    } 

    private void doFileUpload(){ 

     try{ 

     String urlString = "http://twiliosms.ashrafnaim.com/imgUpload/audio.php"; 

     File file=new File(selectedPath); 

     RequestParams params = new RequestParams(); 
     params.put("uploadedfile",file); 
     AsyncHttpClient client = new AsyncHttpClient(); 
     client.post(urlString, params,new AsyncHttpResponseHandler() { 
      @Override 
      public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) { 

       prgDialog.cancel(); 
       String s=new String(responseBody); 
       Toast.makeText(AudioActivity.this,s,Toast.LENGTH_LONG).show(); 

      } 

      @Override 
      public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) { 

       prgDialog.cancel(); 

      } 
     }); 

     } 
     catch (Exception e) 
     { 
      prgDialog.cancel(); 
     } 
    } 
}
