android - 如何使用 Oreo 及更高版本上的广播接收器检测 android 中的拨出呼叫状态？

Question

谁能提供我在 Android Oreo 及更高版本上检测拨出呼叫状态的示例代码？

我的代码在 android 6 上运行良好，但不适用于 Android 8.1 和 Android 9。几乎所有关于堆栈溢出的答案都包含不推荐使用的代码。

广播接收器

public class CallReceiver extends BroadcastReceiver{

    private static int lastState = TelephonyManager.CALL_STATE_IDLE;
    private static Date callStartTime;
    private static boolean isIncoming;
    private static String savedNumber;

    @Override
    public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) {
            savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");

        } else {
            String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
            String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
            int state = 0;
            if (stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
                state = TelephonyManager.CALL_STATE_IDLE;
            } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
                state = TelephonyManager.CALL_STATE_OFFHOOK;
            } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
                state = TelephonyManager.CALL_STATE_RINGING;
            }

            onCallStateChanged(context, state, number);
        }
    }
        public void onCallStateChanged(Context context, int state, String number) {
            if(lastState == state){
                //No change, debounce extras
                return;
            }
            switch (state) {
                case TelephonyManager.CALL_STATE_RINGING:
                    isIncoming = true;
                    callStartTime = new Date();
                    savedNumber = number;

                    Toast.makeText(context, "Incoming Call Ringing" , Toast.LENGTH_SHORT).show();
                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    //Transition of ringing->offhook are pickups of incoming calls.  Nothing done on them
                    if(lastState != TelephonyManager.CALL_STATE_RINGING){
                        isIncoming = false;
                        callStartTime = new Date();
                        Toast.makeText(context, "Outgoing Call Started" , Toast.LENGTH_SHORT).show();
                    }

                    break;
                case TelephonyManager.CALL_STATE_IDLE:
                    //Went to idle-  this is the end of a call.  What type depends on previous state(s)
                    if(lastState == TelephonyManager.CALL_STATE_RINGING){
                        //Ring but no pickup-  a miss
                        Toast.makeText(context, "Ringing but no pickup" + savedNumber + " Call time " + callStartTime +" Date " + new Date() , Toast.LENGTH_SHORT).show();
                    }
                    else if(isIncoming){

                        Toast.makeText(context, "Incoming " + savedNumber + " Call time " + callStartTime  , Toast.LENGTH_SHORT).show();
                    }
                    else{
                        Toast.makeText(context, "Outgoing "+ savedNumber + " Call time " + callStartTime +" Date " + new Date() , Toast.LENGTH_SHORT).show();                        
                    }

                    break;
            }
            lastState = state;
        }

}

主要活动

public class MainActivity extends AppCompatActivity {

    private CallReceiver callReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        callReceiver = new CallReceiver();
    }

    @Override
    protected void onResume() {
        super.onResume();

        IntentFilter filter = new IntentFilter();
        filter.addAction("android.intent.action.PHONE_STATE");
        filter.addAction("android.intent.action.NEW_OUTGOING_CALL");
        registerReceiver(callReceiver, filter);
    }

    @Override
    protected void onPause() {
        try {

            unregisterReceiver(callReceiver);
        } catch (Exception e) {
            e.getMessage();
        }

        super.onPause();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
    }

}
