I am trying to download a image file on the internet by android and I use this code:

}
}
but in LogCat i have an error. it show that: /sdcard/downloadedfile.jpg (Permission denied).
I am using android 3.1, and I don't know how to solve it, please help me!
thank so much.
Add WRITE_EXTERNAL_STORAGE permission to the manifest file.

When i run my code on my phone its running but not working android emulators. What should i do now i am stuck in these things.
D/VideoView: Error: 1,0
E/Error:: /sdcard/4.mp4 (Permission denied)
W/MediaPlayer: Couldn't open /sdcard/4.mp4: java.io.FileNotFoundException: No content provider: /sdcard/4.mp4
W/VideoView: Unable to open content: /sdcard/4.mp4
java.io.FileNotFoundException: /sdcard/4.mp4 (Permission denied)
If your app run correctly on your phone and does not work on emulator,
these can be happen
Your Manifest file should include permissions like a
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Maybe your phone SDK Version and emulator have different sdk try it same sdk version emulator with you phone.

You can use foreground Notification.Here is your Example
project demonstrating the use of startForeground().
i am download some data from URL. and i want to display the number of bytes and the % of bytes download together in the progress dialog.
now i can only show the % of bytes downloads.
here is my code

// Image view to show image after downloading

this code only show the download progress in %. but i want to show the download progress in % as well as total no of bytes download.
You can do this :
publishProgress("" + (int) ((total * 100) / lenghtOfFile)+ "lengthOfFile="+lengthOfFile); //You can use as a thing to split variable.Here, i used the name "lengthOfFile=" and i will get this through publish progress and split it there
#Override
protected void onProgressUpdate(String... values) {
// TODO Auto-generated method stub
super.onProgressUpdate(values);
String str[]=values[0].split("lengthOfFile=");
String percent=str[0];
String bytes=str[1];
}
I am developing an app that downloads files and show 2 progress bars, the first one for the current downloading file, and the 2nd one for total progress based on the number of files.
I am using the DoubleProgressBar library in my app:
I succeeded to update the first ProgressBar, but stuck with the 2nd one.
Here is my code for the AsyncTask class:
private DoubleProgressDialog pDialog;
class DownloadFileFromURL extends AsyncTask<String, Integer, String> {
Context mContext;
public DownloadFileFromURL(Context ctx) {
// TODO Auto-generated constructor stub
this.mContext = ctx;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
showDialog(CUSTOM_PROGRESS_DIALOG);
}
/* Downloading file in background thread */
#Override
protected String doInBackground(String... f_url) {
InputStream input = null;
OutputStream output = null;
HttpURLConnection connection = null;
try {
URL url = new URL(f_url[0]);
connection = (HttpURLConnection) url.openConnection();
connection.connect();
// getting file length
int fileLength = connection.getContentLength();
for (int i = 0; i <= ArrayOfFiles.length; i++){
File f = new File(Environment.getExternalStorageDirectory() + "/Folder/", ArrayOfFiles[i]);
// input stream to read file - with 8k buffer
input = new BufferedInputStream(url.openStream(), 8192);
// Output stream to write file
output = new FileOutputStream(f);
byte data[] = new byte[8192];
long total = 0;
int count;
int EntireProgress = 0;
while ((count = input.read(data)) != -1) {
// allow canceling with back button
if (isCancelled()) {
input.close();
return null;
}
total += count;
// publishing the progress....
if (fileLength > 0) // only if total length is known
publishProgress((int)(total * 100 / fileLength));
output.write(data, 0, count);
/*Here is my trouble, the 2nd ProgressBar is updating as the same of the first one, I need the 2nd one to update itself slowly till all files get downloaded*/
int CurrentProgress = pDialog.getProgress();
pDialog.setSecondaryProgress(CurrentProgress );
publishProgress(CurrentProgress );
}
} catch (Exception e) {
return e.toString();
} finally {
try {
if (output != null)
output.close();
if (input != null)
input.close();
}
} catch (IOException ignored) {
}
if (connection != null)
connection.disconnect();
}
return null;
}
#Override
protected void onPostExecute(String result) {
// dismiss the dialog after the file was downloaded
dismissDialog(CUSTOM_PROGRESS_DIALOG);
if (result != null)
Toast.makeText(mContext,"Download error: " + result, Toast.LENGTH_LONG).show();
else
Toast.makeText(mContext,"File downloaded", Toast.LENGTH_SHORT).show();
}
#Override
protected void onProgressUpdate(Integer... progress) {
super.onProgressUpdate(progress);
// if we get here, length is known, now set indeterminate to false
pDialog.setIndeterminate(false);
pDialog.setMax(100);
pDialog.setProgress(progress[0]);
}
}
I also used this method in my activity class:
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case CUSTOM_PROGRESS_DIALOG:
pDialog = new DoubleProgressDialog(NetworkActivity.this);
pDialog.setMessage("Downloading file. Please wait...");
pDialog.setMax(100);
pDialog.setIndeterminate(true);
pDialog.setCancelable(false);
pDialog.setButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.cancel();
}
});
pDialog.show();
return pDialog;
default:
return null;
}
}
Any idea?
First part is to move pDialog.setSecondaryProgress to the onProgressUpdate(Integer... progress) method.
You are also resetting the secondary progress in each download task by setting it to CurrentProgress which is set to pDialog.getProgress();. Hence the second progress will always be reset after the download is finished.
Edit:
// publishing the progress....
if (fileLength > 0) // only if total length is known
publishProgress((int)(total * 100 / fileLength), pDialog.getSecondaryProgress());
(...)
int CurrentProgress = pDialog.getProgress();
// do not update secondary progress here
// pDialog.setSecondaryProgress(CurrentProgress );
int secondaryProgress = (CurrentProgress + 100 * i)/ArrayOfFiles.length;
publishProgress(CurrentProgress, secondaryProgress);
And the onProgressUpdate
#Override
protected void onProgressUpdate(Integer... progress) {
super.onProgressUpdate(progress);
(...)
pDialog.setProgress(progress[0]);
pDialog.setSecondaryProgress(progress[1]);
}
If you are not setting your DownloadFileFromUrl outside your main class I would suggest something like this
int CurrentProgress = pDialog.getProgress();
int secondaryProgress = (CurrentProgress + 100 * id_treated_file)/number_of_files;
// id_treated_file - 0, 1, 2, ... , number_of_files - 1
pDialog.setSecondaryProgress(CurrentProgress);
// secondaryProgress will be progress[1] in your onProgressUpdate method
publishProgress(CurrentProgress, secondaryProgress);
your onProgressUpdate method should look like this :
#Override
protected void onProgressUpdate(Integer... progress) {
super.onProgressUpdate(progress);
// if we get here, length is known, now set indeterminate to false
pDialog.setIndeterminate(false);
pDialog.setMax(100);
pDialog.setProgress(progress[0]);
pDialog.setSecondaryProgress(progress[1]);
}
EDIT
or you can try
pDialog.setSecondaryProgress((progress[0] + 100 * id_treated_file)/number_of_files);

I wanna create download app from url using android code like download manager
but really I don't know how to start
thanks for any help or any video tuts
Thats quite easy
http://developer.android.com/reference/android/app/DownloadManager.html
Example: http://androidtrainningcenter.blogspot.co.at/2013/05/android-download-manager-example.html
/**
* Start Download
*/
public void startDownload() {
DownloadManager mManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
Request mRqRequest = new Request(
Uri.parse("http://androidtrainningcenter.blogspot.in/2012/11/android-webview-loading-custom-html-and.html"));
mRqRequest.setDescription("This is Test File");
// mRqRequest.setDestinationUri(Uri.parse("give your local path"));
long idDownLoad=mManager.enqueue(mRqRequest);
}
But be sure you are min. on API 9
this code will download any file from url just replace the url and location..
