Default phone call - How to select a number service during a call?

I am making a default phone call. Everything works well till I made a call to the switchboard operator.
In this kind of call, the phone says: "Press 1 to do A, press 2 to do B".
I did some research for hours but couldn't find one...
I did try this code, but it doesn't work.
keyPressed(KeyEvent.KEYCODE_1); // when press key 1
private void keyPressed(int keyCode) {
....
Intent i = new Intent(Intent.ACTION_CALL, Uri.parse("tel://" + keyCode));
startActivity(I);
....
playTone(ToneGenerator.TONE_DTMF_1, TONE_LENGTH_INFINITE);
}
Big thanks for any of your suggestions!
Added 1:
I am using InCallService like this:
class CallService : InCallService() {
private var isShowEnded = true
override fun onCallAdded(call: Call) {
super.onCallAdded(call)
OngoingCall().setCall(call)
CallActivity.getInstance().start(this, call)
isShowEnded = false
}
override fun onCallRemoved(call: Call) {
super.onCallRemoved(call)
OngoingCall().setCall(null)
}
}
and OngoingCall:
public class OngoingCall {
public static BehaviorSubject<Integer> state = BehaviorSubject.create();
private static Call sCall;
public Call getsCall() {
return sCall;
}
#RequiresApi(api = Build.VERSION_CODES.M)
private Object callback = new Call.Callback() {
#Override
public void onStateChanged(Call call, int newState) {
super.onStateChanged(call, newState);
state.onNext(newState);
}
};
#RequiresApi(api = Build.VERSION_CODES.M)
public final void setCall(#Nullable Call value) {
if (sCall != null) {
sCall.unregisterCallback((Call.Callback) callback);
}
if (value != null) {
value.registerCallback((Call.Callback) callback);
state.onNext(value.getState());
}
sCall = value;
}
#RequiresApi(api = Build.VERSION_CODES.M)
public void answer() {
if (sCall != null) {
assert sCall != null;
sCall.answer(VideoProfile.STATE_AUDIO_ONLY);
}
}
#RequiresApi(api = Build.VERSION_CODES.M)
public void hold(boolean hold) {
if (sCall != null) {
if (hold) sCall.hold();
else sCall.unhold();
}
}
#RequiresApi(api = Build.VERSION_CODES.M)
public void addCall(Call call) {
if (sCall != null) {
sCall.conference(call);
}
}
#RequiresApi(api = Build.VERSION_CODES.M)
public void hangup() {
if (sCall != null) {
sCall.disconnect();
}
}
}
And then I tried this when pressing keyboard:
mTrueCallerOngoingCall.getsCall().playDtmfTone((char) tone); // inside playTone()
But it's still not working :(
Update 2:
I have fixed my adding this method:
private char getChar(int tone) {
if (tone == 0) return '0';
else if (tone == 1) return '1';
else if (tone == 2) return '2';
else if (tone == 3) return '3';
else if (tone == 4) return '4';
else if (tone == 5) return '5';
else if (tone == 6) return '6';
else if (tone == 7) return '7';
else if (tone == 8) return '8';
else if (tone == 9) return '9';
else if (tone == 10) return '*';
else return '#';
}
and change from my above code to
mTrueCallerOngoingCall.getsCall().playDtmfTone(getChar(tone));
mTrueCallerOngoingCall.getsCall().stopDtmfTone();

It is .Hope can help you.
call.playDtmfTone(char);
The call PATH:
android.telecom.Call;
From: Any Class extends InCallService.
In Method: onCallAdded(call);

Some time Intent service crash on start service again in Response Receiver

I solve it after doing some debugging startService(servicedriver); servicedriver object is null I start it again if it is null like
if(servicedriver!=null) {
startService(servicedriver);
}
else{
startservice();
}
here is start service
public void startservice() {
if (sharedData.getisSimulation() == true) {
jmode = true;
sharedData.setisRating(false);
servicedriver = new Intent(this, LocationService.class);
this.startService(servicedriver);
sharedData.setJmode(true);
}
if (sharedData.getisSimulation() == false) {
jmode = true;
sharedData.setisRating(false);
servicedriver = new Intent(this, LocationServiceDriver.class);
this.startService(servicedriver);
sharedData.setJmode(true);
}
}

Bluetooth streaming is lagging Android app

I'm writinng Android app that receiving data via bluetooth from another device. Those data as in fact streaming non-stop. After getting about 50 or 70 of them, app slows down and stop showing me received data. App cache is full, but clearing it (deleting context.getCacheDir()) doesn't help. After restarting whole app, I can again get next part of data. WHat can I do for avoiding this "lag"?

Android: update UI from thread

To update a seekbar, I am using the following code:
My problem is that anytime the seekBar.setProgress() is call, other element on the UI become freezed, so I would like to have a different thread that update the seekBar in the main thread.
How to proceed ?
private Handler mHandler = new Handler() {
#Override
public void handleMessage(Message msg) {
try {
int pos;
switch (msg.what) {
case SHOW_PROGRESS:
pos = setProgress();
if (!mDragging && mBoundService.isPlaying()) {
msg = obtainMessage(SHOW_PROGRESS);
sendMessageDelayed(msg, 100 - (pos % 1000));
}
break;
}
} catch (Exception e) {
}
}
};
private int setProgress() {
if (mBoundService == null || mDragging) {
return 0;
}
int position = mBoundService.getCurrentPosition();
int duration = mBoundService.getDuration();
if (sliderSeekBar != null) {
if (duration > 0) {
// use long to avoid overflow
long pos = 1000L * position / duration;
sliderSeekBar.setProgress((int) pos);
}
}
if (sliderTimerStop != null)
sliderTimerStop.setText(stringForTime(duration));
if (sliderTimerStart != null)
sliderTimerStart.setText(stringForTime(position));
return position;
}

Activities have a runOnUiThread method that allows separate threads to update UI components. Your setProgress method would end up looking like:
private int setProgress() {
if (mBoundService == null || mDragging) {
return 0;
}
final int position = mBoundService.getCurrentPosition();
final int duration = mBoundService.getDuration();
runOnUiThread(new Runnable(){
#Override
public void run(){
if (sliderSeekBar != null) {
if (duration > 0) {
// use long to avoid overflow
long pos = 1000L * position / duration;
sliderSeekBar.setProgress((int) pos);
}
}
if (sliderTimerStop != null)
sliderTimerStop.setText(stringForTime(duration));
if (sliderTimerStart != null)
sliderTimerStart.setText(stringForTime(position));
}
});
return position;
}

Android, Handler's error

This is a bit weird, but I have no idea where the problem is.
In my onCreate() I have this code:
GameRunningNotesTimer().start();
and then out of onCreate I have this code:
Thread GameRunningNotesTimer = new Thread(new Runnable() {
public void run() {
int sleepingTime;
try {
if (r_settings.getGameOver() == 0) {
sleepingTime = 1000 - (r_settings.getInternalLevel() * 100);
if (r_settings.getInternalLevel() == 0) {
Thread.sleep(1000);
} else {
if (sleepingTime <= 399)
{
sleepingTime = 350;
}
Thread.sleep(sleepingTime);
}
if (r_settings.getGameOver() == 1){ gameOver(); }
myHandler2.sendEmptyMessage(0);
} // End of if (r_settings.getGameOver()
} catch (Exception e) { Log.e("MUSIC!!!!!", "Error in activity", e); }
}// End of run
}); // End of GameRunningNotesTimer()
final Handler myHandler2 = new Handler() {
#Override
public void handleMessage(Message msg) {
//text2.setText(""+item[0]);
int z = 1;
if (r_settings.getGameStarted() == true)
{
changeNoteFromTimer();
} else {
startingCountdown(z);
}
} // end of handleMessage()
};
but this GameRunningNotesTimer().start(); is underlined in red (in Eclipse) and when I mouseover it it says: The method GameRunningNotesTimer() is undefined for the type GameScr
What am I doing wrong? another thread/handler in the same class is not giving me this problem.
Thanks!

It should be GameRunningNotesTimer.start(); not GameRunningNotesTimer().start();
