안드로이드 자바 개발: CallReceiver

통화 수신 시 동작을 처리하는 클래스입니다.

public class CallReceiver extends BroadcastReceiver {
private String previousState = "";

	@Override
	public void onReceive(Context context, Intent intent) {
	    if (intent.getAction().equals("android.intent.action.PHONE_STATE")) {
	        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
	
	        if (state != null && !state.equals(previousState)) {
	            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
	                handleRingingCall(context, intent);
	            } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
	                handleActiveCall(context, intent);
	            } else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
	                handleIdleCall(context, intent);
	            }
	            previousState = state;
	        }
	    }
	}

	private void handleRingingCall(Context context, Intent intent) {
	    String phone = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
	    if (phone != null) {
	        System.out.println("통화 수신 확인");
	        // 수신 번호 가져옴
	        phoneNumtoReport = phone;
	
	    }
	}

	private void handleActiveCall(Context context,Intent intent) {
	    String phone = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
	    if (phone != null) {
	        System.out.println("통화 중 확인");
	
	    }
	}

	private void handleIdleCall(Context context, Intent intent) {
	    String phone = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
	    if (phone != null) {
	        System.out.println("통화 종료 확인");
	        phoneNumtoReport = phone;
	    }
	}
}

Manifest 파일에 다음 코드를 추가하여 완성합니다.

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CALL_LOG"/>

<application
	<receiver
        android:name=".CallReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
	</receiver>
</application>
