I download audio files from server using
try {
// URL url = new URL("http://commonsware.com/misc/test2.3gp");
URL url = new URL("http://192.168.0.2/supplications/"+fileName);
//URL url = new URL("http://www.msoftech.com/supplications/android/"+fileName);
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
Log.v("log_tag", "PATH: " + PATH);
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, fileName);
FileOutputStream fos = new FileOutputStream(outputFile);
InputStream is = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = is.read(buffer)) != -1)
{
fos.write(buffer, 0, len1);
}
fos.close();
is.close();
} catch (IOException e) {
Log.d("log_tag", "Error: " + e);
}
Log.v("log_tag", "Check: " +cd2);
Here PATH = "/data/data/packagename/sounds/filename
It works fine, audio file downloaded and played successfully, but my problem is when I click the home button and then restart the app means the folder with the downloaded audio was not found, ie, when exit the app means all the downloaded audios were deleted automatically. It throws the exception file not found.
For playing the downloaded file I used the code as below,
public void audioPlayer(String path, String fileName) throw FileNotFoundException
{
//set up MediaPlayer
FileInputStream fileInputStream = new FileInputStream(PATH+"/"+fileName);
//String command = "chmod 666 " + recordFile.toString();
try {
mp.setDataSource(fileInputStream.getFD());
// mp.setDataSource(path+"/"+filename.mp3);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
whats the problem with it what I have to do for saving the audio file permenantly.
There is nothing problem in your code it is a file permission issue.
When you download file into internal file system under application package a security is assigned to it like "-rw------" this means your file is accessible for the same application only.As android is on Linux based so every file have some permission.
Your file would be there but not accessible to other application like media player etc, so these application throws error like file not found.(you can check though DDMS tool).
Just change the file path to external drive.
Accept the answer if it is helpful.

I'm using a desktop app java using swing
I'm using JFilechooser to chose the folder to save my excel file
this 1st part is working,the file is well saved. But I need to open it directly after saving it;
I'm using this code the file is found but not open
File xlsx = new File(path + ".xls");
FileInputStream is = null;
try {
is = new FileInputStream(xlsx);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
HSSFWorkbook workbook2 = new HSSFWorkbook(is);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (xlsx.isFile() && xlsx.exists()) {
System.out.println("hurray! We've just opened a workbook");
} else {
System.out.println("Ahh! there was an error. Please make sure that the file path is correct.");
}
I found this Desktop.getDesktop().open(file); but it works just if I put my file in desktop I need to open it anywhere I save it
thanks for helping
FOUND ANOTHER SOLUTION
UPDATE:
File xlsx = new File(path + ".xls");
try {
Runtime.getRuntime().exec("rundll32 SHELL32.DLL,ShellExec_RunDLL \"" + xlsx + "\"");
} catch (Exception exception) {
exception.printStackTrace();
} // path from JFileChooser();
I'm relatively new to android, and I'm trying to modify an android app such that it downloads a profile picture (preferably in PNG) from a URL, and saves it in the com.companyName.AppName.whatever/files. It should be noted that the app was initially created in Unity, and just built and exported.
Here's my initial code:
URL url = null;
try {
url = new URL(playerDO.getProfileURL());
} catch (MalformedURLException e) {
e.printStackTrace();
}
InputStream input = null;
try {
input = url.openStream();
} catch (IOException e) {
e.printStackTrace();
}
String fileName = playerDO.getId() + ".png";
FileOutputStream outputStream = null;
try {
outputStream = openFileOutput(fileName, Context.MODE_PRIVATE);
byte[] buffer = new byte[256];
int bytesRead = 0;
while ((bytesRead = input.read(buffer, 0, buffer.length)) >= 0) {
outputStream.write(buffer, 0, bytesRead);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
outputStream.close();
input.close();
} catch (IOException e) {
e.printStackTrace();
}
}
EDIT: Here's my other code, as suggested by #Ashutosh Sagar
InputStream input = null;
Bitmap image = null;
try {
input = url.openStream();
image = BitmapFactory.decodeStream(input);
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
String fileName = playerDO.getId() + ".png";
FileOutputStream outputStream = null;
File myDir = getFilesDir();
try {
Log.wtf("DIRECTORY", myDir.toString());
File imageFile = new File(myDir, fileName);
if (!imageFile.exists()){
imageFile.createNewFile();
Log.wtf("ANDROID NATIVE MSG: WARN!", "File does not exist. Writing to: " + imageFile.toString());
}
outputStream = new FileOutputStream(imageFile, false);
image.compress(Bitmap.CompressFormat.PNG, 90, outputStream);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
outputStream.close();
input.close();
} catch (IOException e) {
e.printStackTrace();
Log.wtf("AWWW CRAP", e.toString());
}
}
(It doesn't write either).
Unfortunately, I've had several problems with this. My primary issue is that when it (on the cases that it does) runs, it actually doesn't save anything. I'll go and check com.companyName.AppName.whatever/files directory only to find no such .png file. I will also need it to overwrite any existing files of the same name, which is hard to check when it doesn't work.
My secondary issue is that it fails to take into account delays in internet connection. Although I've put in enough try-catch clauses to stop it from crashing (as it used to), the end result is that it also doesn't save.
How can I improve upon this? Anything I'm missing?
EDIT:
Printing out the directory reveals it should be in:
/data/user/0/com.appName/files/5965e9e4a0f0463853016e2b.png
However, using ES File explorer, the only thing remotely close to that is
emulated/0/Android/data/com.appName/files/
Are they the same directory?
try this first get bitmap image from url
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(url).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.d("Error", e.getStackTrace().toString());
}
and to save bitmap image please check the ans of GoCrazy
Try this
void getImage(String string_url)
{
//Generate Bitmap from URL
URL url_value = new URL(string_url);
Bitmap image =
BitmapFactory.decodeStream(url_value.openConnection().getInputStream());
//Export File to local Directory
OutputStream stream = new FileOutputStream("path/file_name.png");
/* Write bitmap to file using JPEG or PNG and 80% quality hint for JPEG. */
bitmap.compress(CompressFormat.PNG, 80, stream);
stream.close();
}
Hi i am trying to upload a file using spring data. When i try to upload file, i get an exception.
My code for file upload is
try {
File file = new File(this.TEMPORARY_FILES_DIRECTORY, Calendar.getInstance().getTimeInMillis() + "_" + fileNameUnderscored);
writeByteArrayToFile(file, form.getFile().getBytes());
FileInputStream inputStream = new FileInputStream(file);
GridFSFile gridFSFile = gridFsTemplate.store(inputStream, "test.png");
PropertyImage img = new PropertyImage();
img.setPropertyUid(gridFSFile.getFilename());
imagesRepository.save(img);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
where TEMPORARY_FILES_DIRECTORY = new File("/home/temp/");
the exception i am getting is
java.io.IOException: File '/home/temp/1392807425028_file' could not be created
on debugging FileUtils class
if (parent.mkdirs() == false) {
throw new IOException("File '" + file + "' could not be created");
}
parent.mkdirs() is false.
Can anyone kindly tell me what is wrong with this code.
Are you sure it's /home/temp and not /home/username/temp? You can't create directories outside your home directory. Try something like Systen.getProperty("user.home") + "/temp", if you'd like to store the files inside your home directory. Anyway, why didn't you choose /tmp to be your temporary directory?

This is the way to load HTML file from assets in WebView
webview.loadUrl("file:///android_asset/Untitled-1.html");
Untitled-1.html---File name that should be save first as .html extension
Edited
try this link
http://developer.android.com/reference/android/content/res/AssetManager.html
there is method from this doc
public final String[] list (String path)
You cat get InputStream by this code:
getResources().getAssets().open("you_file_name_goes_here");
you don't want to use
webview.loadUrl('file:///android_asset/htmlFile.html');
right?
try this i found it in a blog:
static String getHTMLDataBuffer(String url,Context context) {
InputStream htmlStream;
try {
if (Utils.isReferExternalMemory() && url.contains("sdcard")) {
String tempPath = url.substring(7, url.length());//remove file:// from the url
File file = new File(tempPath);
htmlStream = new FileInputStream(file);
}else{
String tempPath = url.replace("file:///android_asset/", "");
htmlStream = context.getAssets().open(tempPath);
}
Reader is = null;
try {
is = new BufferedReader(new InputStreamReader(htmlStream, "UTF8"));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// read string from reader
final char[] buffer = new char[1024];
StringBuilder out = new StringBuilder();
int read;
do {
read = is.read(buffer, 0, buffer.length);
if (read>0) {
out.append(buffer, 0, read);
}
} while (read>=0);
return out.toString();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
usage:
String data = getHTMLDataBuffer("file:///android_asset/yourHtmlFile",this);
webview.loadDataWithBaseURL("http://example.com", data, "text/html", "utf-8", null);
Sorry for my bad english :)
