Merhaba tech bak şöyle birşey yapmıştm telefon arandığında çağrı cevaplandığında konuşmayı kaydetmesi için yapmştm. işine yarar sende ona göre modifiye et
2 class dan oluşyr:
bak burada telefona çağrı geldiği durumlar var ona göre start yada stop ediyorm
CustomPhoneStateListener
[code]
package com.example.flashlightexample;
import android.content.Context;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.widget.Toast;
public class CustomPhoneStateListener extends PhoneStateListener {
//private static final String TAG = "PhoneStateChanged";
Context context; //Context to make Toast if required
public CustomPhoneStateListener(Context context) {
super();
this.context = context;
}
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
//when Idle i.e no call
Toast.makeText(context, "Phone state Idle", Toast.LENGTH_SHORT).show();
CagrıAudioRecording.stopRecording();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
//when Off hook i.e in call
//Make intent and start your service here
Toast.makeText(context, "Phone state Off hook", Toast.LENGTH_SHORT).show();
CagrıAudioRecording.startRecording();
break;
case TelephonyManager.CALL_STATE_RINGING:
//when Ringing
Toast.makeText(context, "Phone state Ringing", Toast.LENGTH_SHORT).show();
break;
default:
