New Api AudioPlaybackCaptureConfiguration (android 10) fails to record voice calls

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?

Update foreground service notification with sensor data

I am developing a pedometer. I have a service which is running fine. I made my service foreground also. But how do I update my notification with sensor data. I am getting steps from sensor. I just want to show it in a notification which is showing usig the foreground service.
public class StepCounterService extends Service {
private static final String LOG_TAG = "ForegroundService";
public static Boolean FLAG = false;
private SensorManager mSensorManager;
private StepDetector detector;

}
#Override
public void onCreate() {

super.onCreate();
new StepCountManager(this);
FLAG = true;
Log.e("Service_Started", "");
detector = new StepDetector(this);
mSensorManager = (SensorManager) this.getSystemService(SENSOR_SERVICE);
mSensorManager.registerListener(detector,
mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_NORMAL);
mPowerManager = (PowerManager) this
.getSystemService(Context.POWER_SERVICE);
mWakeLock = mPowerManager.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK

mWakeLock.acquire();
reloadSettings();
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub

if (detector != null) {
mSensorManager.unregisterListener(detector);
}

//Restart the service once it has been killed android

}
}
I just want to show my steps under this notification which I am getting from sensor.
Here is my step_detector class:
public class StepDetector implements SensorEventListener {
public static UpdateStepCount mStepsUpdater;
public static int CURRENT_SETP = 0;
public static float SENSITIVITY = 0; //SENSITIVITY
private float mLastValues[] = new float[3 * 2];

private float mLimit = 10;
private float mLastDirections[] = new float[3 * 2];
private float mLastExtremes[][] = { new float[3 * 2], new float[3 * 2] };
private float mLastDiff[] = new float[3 * 2];
private int mLastMatch = -1;
public StepDetector(Context context) {
// TODO Auto-generated constructor stub
super();
int h = 480;
mYOffset = h * 0.5f;
mScale[0] = -(h * 0.5f * (1.0f / (SensorManager.STANDARD_GRAVITY * 2)));

}
public void setSensitivity(float sensitivity) {

for (int i = 0; i < 3; i++) {
final float v = mYOffset + event.values[i] * mScale[j];
vSum += v;
}
int k = 0;
float v = vSum / 3;
float direction = (v > mLastValues[k] ? 1: (v < mLastValues[k] ? -1 : 0));
if (direction == -mLastDirections[k]) {

if (end - start > 500) {
Log.i("Step_Detector", "CURRENT_SETP:"
+ CURRENT_SETP);
CURRENT_SETP++;
mLastMatch = extType;
start = end;
}
} else {
mLastMatch = -1;
}
}
mLastDiff[k] = diff;
}
mLastDirections[k] = direction;
mLastValues[k] = v;
}
}
}
Log.d("sensorSteps", String.valueOf(CURRENT_SETP));
if(mStepsUpdater!=null){
mStepsUpdater.UpdateStepCount(CURRENT_SETP);
}
}
#Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// TODO Auto-generated method stub
}
public static void callBackInit(StepCountManager stepCountManager) {
mStepsUpdater= stepCountManager;
}
}

If you want to keep your service running even if the app is killed, make sure to return START_STICKY in onStartCommand() as follows :
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// restart service every hour to get the current step count
((AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE))
.set(AlarmManager.RTC, System.currentTimeMillis() + AlarmManager.INTERVAL_HOUR,
PendingIntent.getService(getApplicationContext(), 2,
new Intent(this, SensorListener.class),
PendingIntent.FLAG_UPDATE_CURRENT));
return START_STICKY;
}

You need to start a Foreground Service.

} else {
backgroundThread.start();
}
Log.i(LOG_TAG, "Received Start Foreground Intent ");

audioPlayed = false;
} else {

audioPlayed = true;
}
Log.i(LOG_TAG, "Clicked Play");
} else if (intent.getAction().equals(Constants.ACTION.NEXT_ACTION)) {

}
return START_STICKY;
}

}
#Override

// Used only in case of bound services.
return null;
}
}

return START_STICKY;
to automatically restart the service when it gets killed for some reasons like low memory.

Handling Multiple Downloads With Notifications Using Retrofit Library

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");

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;

.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

// 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();

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();

Android - Passing long array via broadcast intent

I wrote a little android program, there is a main activity with a broadcast listener, and i create another thread. The thread searches for prime numbers, and loading them into a long arraylist, and after every 3 seconds, sends the filled array to the main activity via broadcast. Everythings ok, until i'm trying to get the long array extra from the intent. It causes every time a nullpointerexception.
I tried with a string arraylist, it worked, but i am curious because the intent has an "getlongarrayextra" method.
Here is my code:
public class MainActivity extends Activity {
public static String BROADCAST_THREAD_KEY = "broadcast_key";
public static String EXTRAARRAYID = "primes";
private static long MAXNUM = 2000000;
private PrimeCalculatorThread thread;
TextView textView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.numberstext);
}
private BroadcastReceiver receiver = new BroadcastReceiver() {
public void onReceive(android.content.Context context,
android.content.Intent intent) {
String origitext = textView.getText().toString();
long[] primes = intent.getExtras().getLongArray(EXTRAARRAYID);
Log.d("ASD", "broadcast received" + primes.toString());
StringBuilder builder = new StringBuilder();
if (primes != null) {
for (long prime : primes) {
builder.append(prime + " - ");
}
textView.setText(origitext + "\n" + builder.toString());
}
};
};
#Override
protected void onResume() {
Log.d("ASD", "ONRESUME");
initReceiverAndStartThread();
super.onResume();
}
private void initReceiverAndStartThread() {
IntentFilter filter = new IntentFilter(BROADCAST_THREAD_KEY);
registerReceiver(receiver, filter);
thread = new PrimeCalculatorThread(getBaseContext(), MAXNUM);
thread.start();
Log.d("ASD", "THREAD STARTED");
}
and the second thread:
public class PrimeCalculatorThread extends Thread {
private Context context;
private long maxnum;
List<Long> primes;
boolean isrunning;
public void setIsrunning(boolean isrunning) {
this.isrunning = isrunning;
}
private long counter = 0;
private long DELAYBETWEENBROADCAST = 3000;
public PrimeCalculatorThread(Context c, long maxnum) {
this.context = c;
this.maxnum = maxnum;
primes = new ArrayList<Long>();
}
#Override
public void run() {
long startTime = System.currentTimeMillis();
long estimatedTime;
isrunning = true;
for (long i = 0; i < maxnum; i++) {
Log.d("ASD", Boolean.toString(isrunning));
if (!isrunning)
break;
Log.d("ASD", i + "");
estimatedTime = System.currentTimeMillis() - startTime;
if (isPrime(i)) {
primes.add(i);
Log.d("ASD", i + "is a prime");
} else {
Log.d("ASD", i + "is not a prime");
}
if (estimatedTime > counter * DELAYBETWEENBROADCAST
+ DELAYBETWEENBROADCAST) { // elapsed another period
Log.d("ASD", primes.toString() + " will be sending.");
sendBroadCast();
primes.clear();
counter++;
}
try { //for debug purposes
Thread.sleep(250);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
private void sendBroadCast() {
Intent intent = new Intent(MainActivity.BROADCAST_THREAD_KEY);
intent.putExtra(MainActivity.EXTRAARRAYID, primes.toArray());
context.sendBroadcast(intent);
Log.d("ASD", "BROADCAST SENT" + primes.toString());
}
boolean isPrime(long n) {
if (n < 2)
return false;
if (n == 2 || n == 3)
return true;
if (n % 2 == 0 || n % 3 == 0)
return false;
long sqrtN = (long) Math.sqrt(n) + 1;
for (long i = 6L; i <= sqrtN; i += 6) {
if (n % (i - 1) == 0 || n % (i + 1) == 0)
return false;
}
return true;
}
}

The problem is that you are managing a list of Long objects and passing it in putExtra, which means you are invoking putExtra(String name, Serializable value). Then you try to get that value using getLongArray(), but you haven't put any long array extra, you see! To solve this, replace
intent.putExtra(MainActivity.EXTRAARRAYID, primes.toArray());
with
long[] primesArray = new long[primes.size()];
for (int i = 0; i < primes.size(); i++) {
primesArray[i] = primes.get(i);
}
intent.putExtra(MainActivity.EXTRAARRAYID, primesArray);
This will invoke the correct putExtra(String name, long[] value) method.

Download Manager failed the download

I am using DownloadManager to download the following url:
http://dj-videos.us/Music/XclusiveSinGleTrack/320%20Kbps/November%202013/Yo%20Yo%20Honey%20Singh%20-%20Blue%20Eyes-[DJKANG.Com].mp3

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;
}
