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();
