android

Bluetooth 関連にてぬるぽな例外が云々との相談あり。
以下な属性が定義されてて

    private BroadcastReceiver mybcr;

onCreate のいっちゃんケツで以下なナニ。

        mybcr = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String act = intent.getAction();
                if (BluetoothDevice.ACTION_FOUND.equals(act)) {
                    BluetoothDevice device = intent
                            .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                }
            }
        };

上記の intent.getAction() の呼び出しの中で、ぬるぽな例外を吐いている模様。これは正に sixth sense なナニだな (わら
ぬるぽを吐いてるあたりのログが以下。

上記の 73 行目が

                String act = intent.getAction();

って事なんですが、この onReceive ってメソドは onCreate では呼び出されないはずなんですがねぇ。てか stacktrace 的に getAction も呼び出されてないし onReceive も無いんですが。
とりあえず返信入れて思考停止。
