I'm following a tutorial to download files using the Retrofit library.
My app's UI has several different buttons which download different files using the above method. The problem is when someone presses another button after pressing the first, it's queued and starts after the first finishes. I want it to start right away simultaneously.
Here's the code for the DownloadService:
public class DownloadService extends IntentService {
public DownloadService() {
super("Download Service");
}
private int totalFileSize;
private NotificationCompat.Builder notificationBuilder;
private NotificationManager notificationManager;
#Override
protected void onHandleIntent(Intent intent) {
MyApp x = (MyApp)getApplicationContext();
notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_file_download_deep_orange_a400_18dp)
.setContentTitle("Downloading")
.setContentText("Please wait...")
.setAutoCancel(true);
notificationManager.notify(x.ID, notificationBuilder.build());
Log.i("Paras", "onHandleIntent: " + x.filename + x.url);
initDownload(x.filename,x.url,x.ID);
}
private void initDownload(String filename, String url, int id) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://dl.dropboxusercontent.com/")
.build();
RequestInterface.RetrofitInterface retrofitInterface = retrofit.create(RequestInterface.RetrofitInterface.class);
Call<ResponseBody> request = retrofitInterface.downloadFile(url);
try {
downloadFile(request.execute().body(),filename,id);
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
private void downloadFile(ResponseBody body, String filename,int id) throws IOException {
int count;
byte data[] = new byte[1024 * 4];
long fileSize = body.contentLength();
InputStream bis = new BufferedInputStream(body.byteStream(), 1024 * 8);
File outputFile = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), filename);
OutputStream output = new FileOutputStream(outputFile);
long total = 0;
long startTime = System.currentTimeMillis();
int timeCount = 1;
while ((count = bis.read(data)) != -1) {
total += count;
totalFileSize = (int) (fileSize / (Math.pow(1, 2))) / 1000;
double current = Math.round(total / (Math.pow(1, 2))) / 1000;
int progress = (int) ((total * 100) / fileSize);
long currentTime = System.currentTimeMillis() - startTime;
Download download = new Download();
download.setTotalFileSize(totalFileSize);
if (currentTime > 1000 * timeCount) {
download.setCurrentFileSize((int) current);
download.setProgress(progress);
sendNotification(download,id);
timeCount++;
}
output.write(data, 0, count);
}
onDownloadComplete(filename,id);
output.flush();
output.close();
bis.close();
}
private void sendNotification(Download download, int id) {
sendIntent(download);
notificationBuilder.setProgress(100, download.getProgress(), false);
notificationBuilder.setContentText("Downloading file " + download.getCurrentFileSize() + "/" + totalFileSize + " KB");
notificationManager.notify(id, notificationBuilder.build());
}
private void sendIntent(Download download) {
Intent intent = new Intent(subject.MESSAGE_PROGRESS);
intent.putExtra("download", download);
LocalBroadcastManager.getInstance(DownloadService.this).sendBroadcast(intent);
}
private void onDownloadComplete(String filename,int id) {
try {
Download download = new Download();
download.setProgress(100);
sendIntent(download);
notificationManager.cancel(id);
notificationBuilder.setProgress(0, 0, false);
notificationBuilder.setContentText("Tap to open");
notificationManager.notify(id, notificationBuilder.build());
String path1 = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/" + filename;
File file = new File(path1);
Uri uri_path = Uri.fromFile(file);
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension
(MimeTypeMap.getFileExtensionFromUrl(path1));
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setType(mimeType);
intent.setDataAndType(uri_path, mimeType);
PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);
String string = filename;
notificationBuilder
.setContentIntent(pIntent)
.setAutoCancel(true)
.setContentTitle(string + " Downloaded");
Log.i("Paras", "onDownloadComplete: " + string);
notificationManager.notify(id, notificationBuilder.build());
} catch (Exception ex) {
}
}
#Override
public void onTaskRemoved(Intent rootIntent) {
}
}
Then I read about IntentService and Service classes. Do Service classes allow simultaneous downloads? I tried something like this:
public class DownloadService extends Service {
public DownloadService() {
super();
}
private Looper mServiceLooper;
private ServiceHandler mServiceHandler;
private final class ServiceHandler extends Handler {
public ServiceHandler(Looper looper) {
super(looper);
}
#Override
public void handleMessage(Message msg) {
MyApp x = (MyApp)getApplicationContext();
notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationBuilder = new NotificationCompat.Builder(getBaseContext())
.setSmallIcon(R.drawable.ic_file_download_deep_orange_a400_18dp)
.setContentTitle("Downloading")
.setContentText("Please wait...")
.setAutoCancel(true);
notificationManager.notify(x.ID, notificationBuilder.build());
Log.i("Paras", "onHandleIntent: " + x.filename + x.url);
initDownload(x.filename,x.url,x.ID);
}
}
#Override
public void onCreate() {
// Start up the thread running the service. Note that we create a
// separate thread because the service normally runs in the process's
// main thread, which we don't want to block. We also make it
// background priority so CPU-intensive work will not disrupt our UI.
HandlerThread thread = new HandlerThread("ServiceStartArguments", Process.THREAD_PRIORITY_BACKGROUND);
thread.start();
// Get the HandlerThread's Looper and use it for our Handler
mServiceLooper = thread.getLooper();
mServiceHandler = new ServiceHandler(mServiceLooper);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// For each start request, send a message to start a job and deliver the
// start ID so we know which request we're stopping when we finish the job
MyApp x = (MyApp)getApplicationContext();
Message msg = mServiceHandler.obtainMessage();
msg.arg1 = startId;
msg.obj= intent.putExtra("ID",x.ID);
mServiceHandler.sendMessage(msg);
// If we get killed, after returning from here, restart
return START_STICKY;
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}

But it didn't work. Any clues what I should do? I'm ready to give more details if required.
Edit 1: DownloadService runs on a function "startDownload" which is executed by various buttons. As you can see in 2nd code, class Extends Service. There is one thread which handles all those button clicks. If you look in comments, it's suggested that I should use Service and different threads for all those clicks. Now how can I make so many threads programmatically. There are almost 40 buttons which make use of DownloadService.
Thanks to #Lxu, I have got it working. So IntentServiceis meant to do one task at a time and can't do multiple tasks simultaneously. We should use Serviceinstead. It allows multiple tasks to be performed simultaneously. We can create multiple threads inside the Service which will be executed simultaneously. My problem got solved by putting all the code of onCreate() to onStartCommand(). When a service is called for the first time, onCreate() is called and after that, it's not called anymore no matter how many times service is called. On every service call, onStartCommand() is executed which creates new thread every time. That's it.
Here's the complete code:
public class DownloadService extends Service {
public DownloadService() {
super();
}
private Looper mServiceLooper;
private ServiceHandler mServiceHandler;
int id1;
int id2;
private final class ServiceHandler extends Handler {

I tried to use new AudioPlaybackCapture method to record some media in an android 10 device.
I managed to record all media sounds such as youtube videos, music etc. But my goal is to check weather we can use this in recording incoming voice calls. I tried to set various values for the usage parameter but with no luck. Always no voice from call is recorded in either case, even with speaker phone on.
I used the following service to record calls. Tried to set
AudioAttributes.USAGE_MEDIA
AudioAttributes.USAGE_VOICE_COMMUNICATION and most other parameters but did not manage to record calls. Other media can be perfectly recorded using this code.
Here's my service, Broadcast massages from an activity is used to invoke start and stop recording functionalities.

This was tested in google pixel device with android 10. Just wanted to know weather this new api can be used in recording calls or media only. Here is the documentation of this new API.
Playback capture.
What would be the possible mistake im doing here?
I'm using the library bitcoinj to create a Android wallet. The case is that I want the blockchain to be downloaded in the background so that the user can start using the other features of the app, but when it starts the download and opens a new activity, the application freezes, you can't use anything, not even return to the previous screen. This is part of the code:

I used part of the code of the official project of the Android wallet
Service in android runs in UI thread. You need to put all the job into different thread inside your Service
You need to use IntentService for downloading process.

Calling my Intent service simply
Intent intentservice = new Intent(MainActivity.this, UIIntentService.class);
startService(intentservice);
This code is working fine and I am receiving progress updates of single download operation.
Now, I want to use this IntentService to perform multiple download operations with progress update of each operation. can you please check whether is it possible through this code or provide some other alternative solution.
Thanks in advance.
Using Handler you can achieve the result.
Please see here.
I am using DownloadManager to download the following url:

But I still need to know which format to use to parse url for DownloadManager.
The IllegalArgumentException occurs when the URL contains illegal characters such as [ ]. As mentioned in the comments, you need to encode such characters using URLEncoder.
I implemented it this way in my code -
private String checkUrl(String url) {
if(url.contains("[")) {
String[] a = url.split("\\[");
String b = "[" + a[1]; //contains text after [ e.g. [DJKANG.Com].mp3
url = a[0] + URLEncoder.encode(b, "UTF-8"); // encodes illegal characters
}
return url;
}
I am using .net web services and I am able to download the file in sd card, But I want to show progress bar when particular file start download and complete and then I want to show options like view and cancel.

Please suggest how to use download manager into it??? thanks
You could use a ProgressBar to accomplish this.
First, add a progressbar to your interface like this:
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#android:style/Widget.ProgressBar.Small"/>
Then in your code update your method like this:
protected ProgressBar mProgressBar;
protected long downloadId;
protected DownloadManager manager;
public void startdownload() {
//<SET UP DOWNLOAD MANAGER HERE>
downloadId = manager.enqueue(request);
mProgressBar = findViewById(R.id.progress_bar);
Timer myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
DownloadManager.Query q = new DownloadManager.Query();
q.setFilterById(downloadId);
Cursor cursor = manager.query(q);
cursor.moveToFirst();
int bytes_downloaded = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
int bytes_total = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES));
cursor.close();
int dl_progress = (bytesDownloaded * 1f / bytesTotal) * 100;
runOnUiThread(new Runnable(){
#Override
public void run(){
mProgressbar.setProgress((int) dl_progress);
}
});
}
}, 0, 10);
}
Use Follow Method
private NotificationManager mNotifyManager;
case R.id.btnSubmit:
mNotifyManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mBuilder = new NotificationCompat.Builder(context);
mBuilder.setContentTitle("BuyMixTapes")
.setContentText("Download in progress")
.setSmallIcon(R.drawable.appiconmain);
new DownloadFile().execute(vv);
public class DownloadFile extends AsyncTask<String, String, String> {
/**

* Show Progress Bar Dialog
*/
#Override
protected void onPreExecute() {
super.onPreExecute();
//context.showDialog(progress_bar_type);
mBuilder.setProgress(100, 0, false);
mNotifyManager.notify(id, mBuilder.build());
}
protected String doInBackground(String... f_url) {
int count;
try {
for (int i = 0; i < f_url.length; i++) {
Log.e("0url",""+f_url[0]);
Log.e("1url",""+f_url[1]);
// Log.e("1url",""+f_url[1]);
URL url = new URL(f_url[i]);
URLConnection conection = url.openConnection();
conection.connect();
// getting file length
int lenghtOfFile = conection.getContentLength();
// input stream to read file - with 8k buffer
InputStream input = new BufferedInputStream(url.openStream(), 8192);
// Output stream to write file
// OutputStream output = new FileOutputStream("/sdcard/"+f_url[i]);
OutputStream output = new FileOutputStream(
"/sdcard/" +i + "buymix.mp3");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
publishProgress("" + (int) ((total * 100) / lenghtOfFile));
// writing data to file
output.write(data, 0, count);
}
// flushing output
output.flush();
// closing streams
output.close();
input.close();
}
} catch (Exception e) {
Log.e("Error: ", e.getMessage());
}
return null;
}
/**

/**

#Override
protected void onProgressUpdate(String... values) {
// Update progress
mBuilder.setProgress(100, Integer.parseInt(values[0]), false);
mNotifyManager.notify(id, mBuilder.build());

Update 2021:
Add a ProgressBar in your layout (TextView is just for showing more information):
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/progressBar"
android:text="Hello World!" />
Then before onCreate:
DownloadManager downloadManager;
long downloadReference;
TextView text1;
ProgressBar progressBar;
Timer progressTimer;
Afterwards, in onCreate:
text1 = (TextView) findViewById(R.id.textView1);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
Then after setting up download manager:
// <Some codes which setup download manager>
downloadReference = downloadManager.enqueue(request); // enqueue a new download
// update progressbar
progressTimer = new Timer();
progressTimer.schedule(new TimerTask() {
#Override
public void run() {
DownloadManager.Query downloadQuery = new DownloadManager.Query();
downloadQuery.setFilterById(downloadReference);
Cursor cursor = downloadManager.query(downloadQuery);
if (cursor.moveToFirst()) { // this "if" is crucial to prevent a kind of error
final int downloadedBytes = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
final int totalBytes = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES)); // integer is enough for files under 2GB
cursor.close();
final float downloadProgress = downloadedBytes * 100f / totalBytes;
if(downloadProgress > 99.9) // stop repeating timer (it's also useful for error prevention)
progressTimer.cancel();
runOnUiThread(new Runnable() {
#Override
public void run() {
text1.setText(downloadedBytes + "\n" + totalBytes + "\n" + downloadProgress + "%");
progressBar.setProgress((int) downloadProgress);
}
});
}
}
}, 0, 1000);
Some tips:
If your file is larger than 2GB, you should use another type instead of int such as double etc.
You can stop timer somewhere else for example, in BroadcastReceiver if you have.
Task executions is every 1000 milliseconds (every 1 second) which is obviously changable.
