Uploading a file from android take ages before calling a function

I'm having a hard time with calling a function when I select on the files.
When I select on a file, it start to take like 10 seconds before it start to call the UploadFile function and then connect to the server, so when I select more files to add, it will take like a minute or so before it start to call the UploadFile function and connect to the server which is wrong. It should have start to call the UploadFile function instantly and connect to the server when I am adding more than one files.
Below is the full code:
public class ComposeActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
private static final int CHOOSE_FILE_REQUESTCODE = 1;
private RecyclerView mFilesDetailRecyclerView;
private ArrayList<String> mSelectedFilesList = new ArrayList<>();
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == CHOOSE_FILE_REQUESTCODE) {
try {
Uri uri = data.getData();
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
int index = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
Context context = getApplicationContext();
FilePath = RealPathUtil.getRealPath(context, uri);
cursor.moveToFirst();
//mSelectedFilesList.add(cursor.getString(index));
mSelectedFilesList.add(FilePath);
mAdapter.notifyItemInserted(mSelectedFilesList.size());
Log.e("message.......", "caught this.....");
upload_File = new File(FilePath);
FileName = upload_File.getName();
new UploadFile().execute();
} catch (Exception e) {
Toast.makeText(ComposeActivity.this, "Choose any other file", Toast.LENGTH_SHORT).show();
}
}

What I am trying to do is when I select on the file and add more files on my mobile app, I want to call the UploadFile function instantly and connect to my server to upload the file in each time when I select on the file. If the server do not response for 10 seconds and the server is offline, I want to store the data in the sqlite database.
I have been told that I should use multi thread and I should also use retrofit. I am not sure if it would be possible to use HttpUrlConnection method with multi thread to connect to the server and upload the files.
Can you please show me an example of what is the best way I could use to get instantly call to a function and connect to the server using with HttpUrlConnection if that is possible??

You start already wrong with trying to get a real path for an uri.
Remove that code.
Then instead of opening a FileInputStream open an InputStream for the uri
InputStream is = getContentResolvet().openInputStream(uri);

Android Upload image using MultipartEntity using GDK

Iam developing a appliction for google glass using GDK and Im trying to upload my captured image using MultiPartEntity but i could not get it work for some reason i can't figure out because its not returning any error. As of now this is where I am.
Java
String picturePath = data.getStringExtra(Intents.EXTRA_PICTURE_FILE_PATH);
final File pictureFile = new File(picturePath);
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("SERVER PATH");
try {
#SuppressWarnings("deprecation")
MultipartEntity entity = new MultipartEntity();
entity.addPart("type", new StringBody("photo"));
entity.addPart("data", new FileBody(pictureFile));
httppost.setEntity(entity);
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
PHP CODE:
$response = array();
$file_upload_url = 'UPLOAD PATH';
if (isset($_FILES['image']['name'])) {
$target_path = $target_path . basename($_FILES['image']['name']);
$email = isset($_POST['email']) ? $_POST['email'] : '';
$website = isset($_POST['website']) ? $_POST['website'] : '';
$response['file_name'] = basename($_FILES['image']['name']);
$response['email'] = $email;
$response['website'] = $website;
try {
// Throws exception incase file is not being moved
if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
// make error flag true
$response['error'] = true;
$response['message'] = 'Could not move the file!';
}
// File successfully uploaded
$response['message'] = 'File uploaded successfully!';
$response['error'] = false;
$response['file_path'] = $file_upload_url . basename($_FILES['image']['name']);
} catch (Exception $e) {
// Exception occurred. Make error flag true
$response['error'] = true;
$response['message'] = $e->getMessage();
}
} else {
// File parameter is missing
$response['error'] = true;
$response['message'] = 'Not received any file!';
}
echo json_encode($response);
?>
Any help would be much appreciated.

That's my code. it's working for me. You can send parameters and files with a progress bar using this code.

and if you are sending to PHP you can use this
<?php
$file_path = "test/";
$username= $_POST["username"];
$password= $_POST["password"];
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {

} else{
echo "fail";
}
?>
Edit - 2:
you can call this AsyncTask like :
String FormData = "username=" + Session.getUsername()
+ "&password=" + Session.getPassword() ;
SendFile SendIt= new SendFile(this, upLoadServerUri, filePath,FormData);
SendIt.execute();

Post parameter to PHP file

I have a code snippet which helps me to get data from my mySQL database. It also works fine ! But now I want to add parameters for my sql query because until now this code only works for this :
mysql_query("SELECT * FROM tablename ORDER BY 5 DESC");
So everything is being outputed.For example I want to use a query like this :
mysql_query("SELECT * FROM tablename WHERE name LIKE "a%" ORDER BY 5 DESC");
That is my code snippet in Android :
public class get_data extends AsyncTask<Void, Void, Boolean>
{
#Override
protected Boolean doInBackground(Void... params) {
String result = null;
InputStream is = null;
StringBuilder sb = null;
str_name_list = new ArrayList<String>();
str_nname_list = new ArrayList<String>();
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("Here is my Link");
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
} catch (Exception e) {
Log.e("log_tag", "Error in http connection" + e.toString());
}
// convert response to string
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line = "0";
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
} catch (Exception e) {
Log.e("log_tag", "Error converting result " + e.toString());
}
// paring data
JSONArray jArray;
try {
jArray = new JSONArray(result);
JSONObject json_data = null;
int anz = jArray.length();
if (anz > 15)
anz = 15;
for (int i = 0; i < anz ; i++) {
json_data = jArray.getJSONObject(i);
str_name_list.add(json_data.getString("NAME"));
str_nname_list.add(json_data.getString("AGE"));
}
} catch (JSONException e1) {
} catch (ParseException e1) {
e1.printStackTrace();
}
return null;
}
}
I found out that I have to add it in HttpEntity but really dont know how without to destroy my code. Thanks in advance !

Before your HTTPResponse, try to add;
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("your value", value));
and then;
httpPost.setEntity(new UrlEncodedFormEntity(params));
I hope this will work!

How can I get the file name/uri of the last taken photo?

I definitely need some help on this one! My problem is that I can't find out how to get the Uri of the last taken photo. I can upload a photo when I choose it from the gallery, but the other feature is missing. The camera starts and after the photo is taken it is saved in the gallery, but somehow I can't find out the URI of the last taken photo. Please help!

You can use this as the path/file where camera stores the photo instead of looking for latest photo.
Uri.fromFile(f)
Camera intent stores the image to the location which you pass it. So may be store the path of the image a global in the activity since it's a temp path that you are passing. And use it the on activity result method to access the file.

resize image before upload to server using php and android

Im using the code below to upload an image to the server using java and PHP, i works fine, but i would like to resize the image before upload to the server, can some help me how to do that THANKS!!

And php code is
< ?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}

You could always try : http://www.thebuzzmedia.com/software/imgscalr-java-image-scaling-library/
Very easy to use.
then you just do :
BufferedImage image = ImageIO.read(file);
image = Scalr.resize(image, 150);
in the .resize you pass in the imgFile and then the size you want. I put 150 here just as an example
