show ProgressBar while file is uploading

I wrote a code in the Android project that uploads a file with a specific name and address to the server. But ProgressBar does not work well and does not show progress and file upload percentage. But the file upload works well and is located on the server. Now I want to show the percentage of progress in the Progress bar when uploading the file to the server to determine how much of the file has been uploaded to the server.
I tried to do this with AsyncTask.
My code ...
private class UploadTask extends AsyncTask<String, Integer, String> {
private final Context context;
public UploadTask(Context context) {
this.context = context;
}
#Override
protected String doInBackground(String... sUrl) {
// take CPU lock to prevent CPU from going off if the user
// presses the power button during download
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
getClass().getName());
wl.acquire(10 * 60 * 1000L /*10 minutes*/);
try {
String fileName = uploadFilePath + uploadFileName;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(uploadFilePath + uploadFileName);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"
+ uploadFilePath + "" + uploadFileName);
getActivity().runOnUiThread(new Runnable() {
#SuppressLint("SetTextI18n")
public void run() {
messageText.setText("Source File not exist :"

}
});
Sneaker.with(getActivity())
.setTitle("Error !")

.sneakError();
} else {

You can use this code to show progress bar when using Asynctask

File upload not working android

I have the following file upload function:
public void uploadFile(Context context, File file) {
String urlServer = "https://u-database.000webhostapp.com/recieve_file.php";
if(file.isFile() && file.exists()) {
String fileName = file.getAbsolutePath();
try {
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
Toast toastw = Toast.makeText(context, "Inside TRY", Toast.LENGTH_SHORT);
toastw.show();
FileInputStream fileInputStream = new FileInputStream(file);
URL url = new URL(urlServer);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("textLog", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"textLog\";filename=\""+fileName+"\""+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);
// Responses from the server (code and message)
int serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Toast toast = Toast.makeText(context, "Uploading", Toast.LENGTH_SHORT);
toast.show();
if(serverResponseCode == 200){
file.delete();
Toast toasto = Toast.makeText(context, "success", Toast.LENGTH_SHORT);
toasto.show();
}
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
Toast toast = Toast.makeText(context, "Malformed URL", Toast.LENGTH_SHORT);
toast.show();
} catch (Exception e) {
Toast toast = Toast.makeText(context, "Exception", Toast.LENGTH_SHORT);
toast.show();
}
}
}
Each time it is executed, a toast appears stating Inside TRY and then another appears stating "Exception".
I have been debugging a lot and any kind of help would be really appreciated :)
UPDATE
When I did e.toString and printed it out to a toast, I got: android.os.NetworkOnMainThreadException

The answer is simple then. You should run your network calls on a background thread. You need to extend AsyncTask and move your code into it. Something like:
private class InitTask extends AsyncTask<Void, Void, Void>{
protected Void doInBackground(Void... p){
// Call upload file code here
}
}

Resolving java.lang.outofmemory error causing half of the file to be uploaded to server

Now files gets uploaded however all file size of 1 MB and that too can not be played.

bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
byte byt[]=new byte[bufferSize];
fileInputStream.read(byt);
You are not writing the bytes read into byt out to the outputstream. Removing the first read into byt should fix a problem. But you will come across another problem where a file over 1MB only the first 1MB will be uploaded.
A proper way to copy a stream is to do something similar to
byte[] buf = new byte[ 1024 ];
int read = 0;
while( ( read = in.read( buf ) ) != -1 ) {
out.write( buf, 0, read );
}

avoid buffering the whole POST data in RAM by adding conn.setChunkedStreamingMode(0); after : con.setDoOutput(true);
hope this help :)

I have not been able to trace the source of this problem and StackOverflow has been great at helping me with other issues. Any suggestions appreciated! Thanks.
Update: I removed the download code since that was not causing an issue
