사용하는 앱은 ActivityGroup으로 구성되어있습니다.

네트워크의 변화를 체크해서

네트워크 연결이 끊어지면 다이얼로그를 띄우는 걸 하려고 합니다.

그래서

BroadcastReceiver를 상속받은 클래스를 receiver에 등록시켜서 확인 중입니다.

근데 문제점은 Dialog가 뜨지않고 강제종료가 되어버립니다.

public class ConnReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
            ConnectivityManager connectivityManager = (ConnectivityManager) context
                    .getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo mobile = connectivityManager
                    .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
            NetworkInfo wifi = connectivityManager
                    .getNetworkInfo(ConnectivityManager.TYPE_WIFI);
            NetworkInfo mobile4g = connectivityManager
                    .getNetworkInfo(ConnectivityManager.TYPE_WIMAX);
            boolean lte_4g = false;
            if (mobile4g != null) {
                lte_4g = mobile4g.isConnected();
            }

            if (wifi.isConnected() || mobile.isConnected() || lte_4g) {
                // Do Something
            } else {
                System.out.println("끊김");
                AlertDialog alert = new AlertDialog.Builder(context)
                        .setTitle("안내").setMessage("끊김")
                        .setPositiveButton("확인", null).show();

            }

        }
    }
}

이유가 뭘까요

보통 context를 넘기면 되던데

예제에도 그렇게 되어있고...ㅠㅠ

ActivityGroup에선 dialog를 띄울 때 context값에 getParent()를 넣거든요

근데 위의 클래스에선 getParent()도 안써지구요

ㅠ이유가 뭘까요

ActivityGroup을 안쓴 액티비티 창에서 네트워크변화체크해서 다이얼로그를 띄워도 같은 에러를 보여주네요 ㅠㅠ
