Sending Image/Text file from Android to Webserver (localhost)

Question

I'm very new to Android Programming, and my task is to send an image and text data to a web server (localhost), I've tried a lot of code to do the job however

all of them wont work. My app just crashes whenever I try to execute the code, so I decided to debug the code and see whats the problem. then I found out that

whenever a MultipartEntity is found, the code just crashes.. I dont really know Why..

The Code goes like this

Log.v(TAG, "(1)");
HttpClient httpClient;
HttpPost postRequest;
Log.v(TAG, "(2)" + picturePath);
MultipartEntity reqEntity;
ResponseHandler<String> responseHandler;
Log.v(TAG, "(3)");
File file;
FileBody fileBody;
Log.v(TAG, "(4)");
httpClient = new DefaultHttpClient();
postRequest = new HttpPost("http://192.168.5.132/mysite/test.php");
responseHandler = new BasicResponseHandler();
Log.v(TAG, "(5)");
    // Indicate that this information comes in parts (text and file)
reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
Log.v(TAG, "(6)");
file = new File(picturePath);
fileBody = new FileBody(file, "images/jpeg");
reqEntity.addPart("fileupload", fileBody);
Log.v(TAG, "(7)");
try {
      reqEntity.addPart("username", new StringBody("un"));
      reqEntity.addPart("password", new StringBody("pw"));

      postRequest.setEntity(reqEntity);
      httpClient.execute(postRequest, responseHandler);
    }
catch (UnsupportedEncodingException e) {
      e.printStackTrace();
}
catch (ClientProtocolException e) {
      e.printStackTrace();
}
catch (IOException e) {
      e.printStackTrace();
}

I have include Logs to the code to see where the code stops during execution. here is the log cat output!

try this code 100% working . the image uploading done through multi-part data passing

?>

the above code 100% working . if you want multi-part entity passing ,try this code on your program necessary place and also code add the $_post method e.g($name=$_POST['username'];)on your php server

entity.addPart("user_id", new StringBody(user_id));
            Log.d("userid",user_id);
            entity.addPart("username", new StringBody(username));
            entity.addPart("password", new StringBody(password));
            entity.addPart("filetype",new StringBody("jpeg"));
            // entity.addPart("photo", new
            // StringBody("/storage/sdcard0/Download/1.jpg"));
            httpPost.setEntity(entity);

            Log.d("URL Request: ", url.toString());

            HttpResponse httpResponse = httpClient.execute(httpPost);
            int code = httpResponse.getStatusLine().getStatusCode(); 

pass the required value to this function and add $_post["username"],$_post["password"] on php

public JSONObject getJSONFromUrl(String url, String username,
            String password,  String photo_path) {
InputStream is = null;
    JSONObject jObj = null;
    static String jsonResp = "";
    String CONTENT_TYPE_JSON = "application/json";
    static String json = "";
    Context context;

        try {
            File file = null;
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            MultipartEntity entity = new MultipartEntity(
                    HttpMultipartMode.BROWSER_COMPATIBLE);

            if(photo_path != null)
                file = new File(photo_path);

            //temp end
            entity.addPart("username", new StringBody(username));
            entity.addPart("password", new StringBody(password));

            entity.addPart("file", new FileBody(file));
            entity.addPart("filetype",new StringBody("jpeg"));
            // entity.addPart("photo", new
            // StringBody("/storage/sdcard0/Download/1.jpg"));
            httpPost.setEntity(entity);

            Log.d("URL Request: ", url.toString());

            HttpResponse httpResponse = httpClient.execute(httpPost);
            int code = httpResponse.getStatusLine().getStatusCode();

            if (code != 200) {
                Log.d("HTTP response code is:", Integer.toString(code));
                return null;
            } else {

Answer 3

Device/Emulator itself a Machine which is having thier own localhost loop.

As you've learned, when you use the emulator, localhost (127.0.0.1) refers to the device's own loop back service, not the one on your machine as you may expect.

Therefore whenever your giving locahost/127.0.0.x that's meant its trying to search your service on your device environment, so it will become fail. because your web-service project are not available on device/emulator loop.

So can use 10.0.2.2 to access your actual machine, it is an alias set up to help in development.

Network Address Space Look into this. http://developer.android.com/tools/devices/emulator.html#networkaddresses

try this,it may help you and is.it's done using AsyncHttpClient library,get the jar file and attach it in your project then use following code to upload any file-

RequestParams params=new RequestParams();

String file = getImagePath().toString();//get path of file you want to upload
        File myfile_one=new  File(file);
try {
    params.put("image1", myfile_one);//image 1 is the key(it uses key-value pair)        
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}


AsyncHttpClient client=new AsyncHttpClient();
    client.post(Constant.url_two, params,new AsyncHttpResponseHandler(){
//here implement the methods of library and write rest of your code
}

you can find other methods to connect to server in the this link.Try it,its really simple
