Download File Progress Dialog

Download File Progress Dialog - android

I want to perform a file download and show a dialog. But when I try to show the dialog I get a error, any help?
The problem is at showDialog(DIALOG_DOWNLOAD_PROGRESS);
Here is the error message : The method showDialog(int) from the type Activity is deprecated
Heres my code:
public class download extends Activity {
public static final int DIALOG_DOWNLOAD_PROGRESS = 0;
private Button startBtn;
private ProgressDialog mProgressDialog;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startBtn = (Button)findViewById(R.id.startBtn);
startBtn.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
startDownload();
}
});
}
private void startDownload() {
String url = "http://practicalbuddhist.com/wp-content/uploads/2012/03/Synapses-Image-for-March-17-2010-Blog-Entry.jpg";
new DownloadFileAsync().execute(url);
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_DOWNLOAD_PROGRESS:
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Running Download Test...");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setCancelable(false);
mProgressDialog.show();
return mProgressDialog;
default:
return null;
}
}
class DownloadFileAsync extends AsyncTask {
#SuppressWarnings("deprecation")
#Override
protected void onPreExecute() {
super.onPreExecute();
showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
#Override
protected String doInBackground(String... aurl) {
int count;
try {
URL url = new URL(aurl[0]);
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new FileOutputStream("/sdcard/Downloadtest.jpg");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
publishProgress(""+(int)((total*100)/lenghtOfFile));
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
} catch (Exception e) {}
return null;
}
protected void onProgressUpdate(String... progress) {
Log.d("ANDRO_ASYNC",progress[0]);
mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}
#SuppressWarnings("deprecation")
#Override

}
}
}

Here is the error message: The method showDialog(int) from the type Activity is deprecated
This is a warning, not an error. You can either upgrade to using Fragments or ignore it.

You can also use ProgressDialog and show() method that is not depracated instead of using showDialog. Declare your dialog in AsyncTask:
class DownloadFileAsync extends AsyncTask<String, String, String> {
private ProgressDialog pDialog;
#Override
protected void onPreExecute()
{
super.onPreExecute();
pDialog = new ProgressDialog(context);
pDialog.setMessage("Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
}
and in onPostExecute() use
pDialog.dismiss();

Android Async - Unzip after file download

I'm trying to create a method within my activity that will unzip the downloaded file to a certain directory. I have tried several different ways and haven't had much luck. I've seen some people use a separate class to do this task, I want to avoid doing that, but if it's my only option then I will do it. Here is my activity:
public class lava_parkour extends Activity {
public static final int DIALOG_DOWNLOAD_PROGRESS = 0;
private Button startBtn;
private ProgressDialog mProgressDialog;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.lava_parkour);
startBtn = (Button)findViewById(R.id.button1);
startBtn.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
startDownload(v);
} });
}
private void startDownload(View v) {
String url = "https://www.dropbox.com/s/lxnizie52efq3e8/lava%20parkour.zip?
dl=1";
new DownloadFileAsync().execute(url);
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_DOWNLOAD_PROGRESS:
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Downloading...");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setCancelable(false);
mProgressDialog.show();
return mProgressDialog;
default:
return null;
}
}
class DownloadFileAsync extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
#Override
protected String doInBackground(String... aurl) {
int count;
try {
URL url = new URL(aurl[0]);
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new
FileOutputStream("/sdcard/games/com.mojang/lava_parkour.zip");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
publishProgress(""+(int)((total*100)/lenghtOfFile));
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
} catch (Exception e) {}
return null;
}
protected void onProgressUpdate(String... progress) {
Log.d("ANDRO_ASYNC",progress[0]);
mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}
#Override
protected void onPostExecute(String unused) {
dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
Toast.makeText(lava_parkour.this, "Process completed! THis map has been added

}
}

Any help is appreciated!

Use the Dialog class methods directly not the Activity helper methods.
In the Dialog API guide at http://developer.android.com/guide/topics/ui/dialogs.html they say explicitly to do not use ProgressDialog but use a custom layout with a ProgressBar.
On the other hand you could just use the DownloadManager to download files asynchrously. Check https://github.com/commonsguy/cw-android/blob/master/Internet/Download/src/com/commonsware/android/download/DownloadDemo.java for a simple example even with notifications.
If you still wants this method check http://www.androidhive.info/2012/04/android-downloading-file-by-showing-progress-bar/ for a simple example using a ProgressDialog-

You are using 2 different instance of DownloadFileAsync in startDownload() and CancelOnClickListener. Try the following code:
public class ExampleActivity extends Activity {
public static final int DIALOG_DOWNLOAD_PROGRESS = 0;
private Button startBtn;
private ProgressDialog mProgressDialog;
DownloadFileAsync dfa = new DownloadFileAsync();
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
startBtn = (Button)findViewById(R.id.startBtn);
startBtn.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
startDownload();
}
});
}
private void startDownload() {
String url = "http://farm1.static.flickr.com/114/298125983_0e4bf66782_b.jpg";
dfa.execute(url);
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_DOWNLOAD_PROGRESS:
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Downloading file..");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setCancelable(true);
mProgressDialog.setButton("Cancel", new CancelOnClickListener());
mProgressDialog.show();
return mProgressDialog;
default:
return null;
}
}
private final class CancelOnClickListener implements DialogInterface.OnClickListener {
public void onClick(DialogInterface dialog, int which) {
ExampleActivity.this.finish();
dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
dfa.cancel(true);
}
}
class DownloadFileAsync extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
#Override
protected String doInBackground(String... aurl) {
int count;
try
{
URL url = new URL(aurl[0]);
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new FileOutputStream("/sdcard/some_photo_from_gdansk_poland.jpg");
byte data[] = new byte[1024];
long total = 0;
if(!isCancelled()){
while (!isCancelled() && (count = input.read(data)) != -1) {
total += count;
publishProgress(""+(int)((total*100)/lenghtOfFile));
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
}
}
catch (Exception e) {
}
return null;
}
protected void onProgressUpdate(String... progress) {
Log.d("ANDRO_ASYNC",progress[0]);
mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}
#Override
protected void onPostExecute(String unused) {
dismissDialog(DIALOG_DOWNLOAD_PROGRESS);

progress dialog for downloading pics

I am downloading roughly 231 pics and would like to have a progress dialog say downloading pics please wait until all the pics are available and then disappear. How would I go about doing this?
protected class DownloadFile extends AsyncTask<String, Integer, String>{
#Override
protected String doInBackground(String... url)
{
int count;
try
{
URL url1 = new URL(url[0]);
URLConnection conexion = url1.openConnection();
conexion.connect();
// this will be useful so that you can show a tipical 0-100% progress bar
int lenghtOfFile = conexion.getContentLength();
// download the file
InputStream input = new BufferedInputStream(url1.openStream());
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1)
{
total += count;
// publishing the progress....
publishProgress((int)(total*100/lenghtOfFile));
}
input.close();
}
catch (Exception e)
{
}
return null;
}
public void onProgressUpdate(Integer... values)
{
super.onProgressUpdate(values);
// here you will have to update the progressbar
// with something like
setProgress(numPokemon);
}
}

I think u have dont wrong thing,
show progress dialog in onpreExecute() , ur logic in doinBackground() and dismiss progress dialog in onPostExecute().
Hope u get it

try this ::
class AddTask extends AsyncTask<Void, Void, Void> {
ProgressDialog pDialog = ProgressDialog.show(Recording.this,"Please wait...", "Retrieving data ...", true);
protected void onPreExecute() {
pDialog.setIndeterminate(true);
pDialog.setCancelable(false);
pDialog.show();
SaxParser(Username,Password);
}
protected Void doInBackground(Void... unused) {
// your code
return(null);
}
protected void onPostExecute(Void unused) {
pDialog.dismiss();
}
}
