After successfully download you can read file with the key that you wrote file to app storage. To do that:
String filePath = fileManager.getFilePath(mp3Key); // filePath returns local url of file
For example, you can do:
mediaPlayer.setDataSource(filePath );

I hope you can fix my problem:
I have got a textureview to takes photos but when he capture photos, the file who need to contain the picture is empty. I don't know where and what is the problem. I just think that the problem is when the file is created. Thank you to help me.

Try with below code:

myDir = new File(root + "/PhotoApp/" + id);
myDir.mkdirs();
count++;
counter.setText(String.valueOf(count));
fname = "" + id + "-" + count + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) file.delete();
This code will create a folder PhotoApp and inside the folder, all the images will store.

I am using Silicompressor library for video compression.
My video size is 15 MB and compressed video size is coming to 500 kb
since the compressed size is very very small and when clicked on play button of compressed video it shows an error as "Failed to play video."
How do I get a compressed size in MB?
Here is my code after compressing
File imageFile = new File(compressedFilePath);
float length = imageFile.length() / 1024f; // Size in KB
System.out.println("length = " + length);
String value;
if (length >= 1024)
value = length / 1024f + " MB";
else
value = length + " KB";
Any other alternative library which works well for video compression ?
you can use LightCompressor library
LightCompressor

Can you go with SiliCompressor. It's nice and simple library and give good result. I have used it.
Try to implement this. If you get any error let me know.
https://github.com/Tourenathan-G5organisation/SiliCompressor
Edit:
This way you can call the async task.
class VideoCompressAsyncTask extends AsyncTask<String, String, String> {
Context mContext;
public VideoCompressAsyncTask(Context context) {
mContext = context;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected String doInBackground(String... paths) {
String filePath = null;
try {
filePath = SiliCompressor.with(mContext).compressVideo(paths[0], paths[1]);
} catch (URISyntaxException e) {
e.printStackTrace();
}
return filePath;
}
#Override
protected void onPostExecute(String compressedFilePath) {
super.onPostExecute(compressedFilePath);
File videoFile = new File(compressedFilePath);
}
}
Then now call it.
new VideoCompressAsyncTask(getActivity()).execute(selectedVideoPath, f.getPath());
selectedVideoPath is the video source path and f.getPath() is the destination path.
Try this way.

if(!ext.equals(".gif")){
name = NoExt + ".jpg";
}
return name;

Toast.makeText(context, "Image saved to " + file.getAbsolutePath(), Toast.LENGTH_SHORT).show();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
For getting GIF using Glide:
Glide.with(MainActivity.this).asFile()
.load(url)
.apply(new RequestOptions()
.format(DecodeFormat.PREFER_ARGB_8888)
.override(Target.SIZE_ORIGINAL))
.into(new Target<File>() {
#Override

}
#Override
public void onResourceReady(#NonNull File resource, #Nullable Transition<? super File> transition) {

}
#Override
public void onLoadCleared(#Nullable Drawable placeholder) {
}
#Override
public void getSize(#NonNull SizeReadyCallback cb) {

public void removeCallback(#NonNull SizeReadyCallback cb) {
}
#Override
public void setRequest(#Nullable Request request) {
}
#Nullable

return null;
}
});
For Saving Image:
private void storeImage(File image) {
File pictureFile = getOutputMediaFile();
if (pictureFile == null) {
return;
}
try {
FileOutputStream output = new FileOutputStream(pictureFile);
FileInputStream input = new FileInputStream(image);
FileChannel inputChannel = input.getChannel();
FileChannel outputChannel = output.getChannel();
inputChannel.transferTo(0, inputChannel.size(), outputChannel);
output.close();
input.close();
Toast.makeText(MainActivity.this, "Image Downloaded", Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private File getOutputMediaFile() {
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/Christmas"); /*getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/Christmas/c");*/
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs())
return null;
}
File mediaFile;
mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_MERRY_CHRISTMAS_"+Calendar.getInstance().getTimeInMillis() +".gif");
return mediaFile;
}
Glide can get File, worked with me:
Glide.with(context).asFile()
.load(url)
.apply(new RequestOptions()
.diskCacheStrategyOf(DiskCacheStrategy.ALL)
.format(DecodeFormat.PREFER_ARGB_8888)
.override(Target.SIZE_ORIGINAL))
.into(new SimpleTarget<File>() {

progressDailog.dismiss();
storeImage(resource);
//Log.d(TAG, "Image : " + resource);
}
});
I'm trying to download a file using an AsyncTask on Android. I want to display a ProgressDialog which should have a progress bar to show the status of the download. I'm using the onProgressUpdate() function for that and implemented a call to publishProgress() in my doInBackground() function. However, the progress dialog only pops up after downloading the file. My code:
protected Long doInBackground(URL...urls) {
for (int i = 0; i < urls.length; i++) {
url = urls[i];
try {
URLConnection conn = url.openConnection();
conn.connect();

I guess the whole file is downloaded when I call new BufferedInputStream(url.openStream()). How can I monitor the download progress?
Wrap URL input stream with you own InputStream that just reads bytes and "monitors" the status, e.g. sends notifications.
It is simple: InputStream is an abstract class with only one abstract method:
public abstract int read() throws IOException;
In your case it should read bytes from stream that it wraps.
public class NotifcationInputStream extends InputStream {
private InputStream in;
private int count;
private Collection<ByteListener> listeners = new ArrayList<ByteListener>();
NotificationInputStream(InputStream in) {
this.in = in;
}
public int read() throws IOException {
int b = in.read();
byteReceived(b);
return b;
}
public void addListener(ByteListener listener) {
listeners.add(listener);
}
private void byteReceived(int b) {
for (ByteListener l : listeners) {
l.byteReceived(b, ++count);
}
}
}
public interface ByteListener extends EventListener {
public void byteReceived(int b, int count);
}
The problem here is how to show the process bar: you have to know total number of bytes. You can get it from HTTP header content-length if your resource is static. Otherwise you need appropriate server support or heuristics.
This code is useful showing download items totol size and downloaded size.
private static final int DOWNLOAD_ONPROGRESS = 1;
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DOWNLOAD_ONPROGRESS:
progressDialog = new ProgressDialog(this);
progressDialog.setMessage("Downloading latest ...");
progressDialog.setCancelable(true);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
try {
progressDialog.show();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return progressDialog;
default:
return null;
}
}
You can use AsyncTask for downloading the version in background.
private class DownLoad extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
logger.info("LoadDataAsync onPreExecute");
showDialog(DOWNLOAD_ONPROGRESS);
}
#Override
protected String doInBackground(String... aurl) {
int count = 0;
try {
URL url = new URL(aurl[0]);
URLConnection urlConnection = url.openConnection();
urlConnection.connect();
int contentlength = urlConnection.getContentLength();
progressDialog.setMax(contentlength);
String PATH = "";
File file = null;
if (android.os.Environment.getExternalStorageState().equals(
android.os.Environment.MEDIA_MOUNTED)) {
PATH = Environment.getExternalStorageDirectory()
+ "/download/";
file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "telfaz.apk");
OutputStream fos = new FileOutputStream(outputFile);
InputStream is = new BufferedInputStream(url.openStream());
byte[] buffer = new byte[1024];
long len1 = 0;
while ((count = is.read(buffer)) != -1
&& !downLoad.isCancelled()) {
len1 += count;
publishProgress("" + len1);
fos.write(buffer, 0, count);
}
fos.flush();
fos.close();
is.close();
}
logger.info("Success -> file downloaded succesfully. returning 'success' code");
return Util.APK_DOWNLOAD_SUCCESS;
} catch (IOException e) {
logger.error("Exception in update process : "
+ Util.getStackTrace(e));
}
logger.info("Failed -> file download failed. returning 'error' code");
return Util.APK_DOWNLOAD_FAILED;
}
#Override
protected void onPostExecute(String result) {
logger.info("on DownLoad onPostExecute. result : " + result);
progressDialog.dismiss();
removeDialog(DOWNLOAD_ONPROGRESS);
if (result.equalsIgnoreCase(Util.APK_DOWNLOAD_SUCCESS)) {
Update();
} else {
Toast.makeText(DownloadAllContentsActivity.this,
getString(R.string.updateApplicationFailed),
Toast.LENGTH_LONG).show();
loadDataAsync.execute();
}
}
#Override
protected void onProgressUpdate(String... values) {
if (values != null && values.length > 0) {
progressDialog.setProgress(Integer.parseInt(values[0]));
}
}
}
