如何监控wifi ap状态的变化

Question

我想找到一种方法来监控WiFi接入点的状态变化，但我发现隐藏了常量WIFI_AP_STATE_CHANGED_ACTION。有没有其他方法来监控这些状态变化？

这是某人的解决方案，但我担心它并不会在所有手机中得到支持。有人能给我一些建议吗？非常感谢。

    public class BroadCastSampleActivity extends Activity {
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    this.registerReceiver(this.mConnReceiver,
            new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
}
private BroadcastReceiver mConnReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        boolean noConnectivity = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);
        String reason = intent.getStringExtra(ConnectivityManager.EXTRA_REASON);
        boolean isFailover = intent.getBooleanExtra(ConnectivityManager.EXTRA_IS_FAILOVER, false);

        NetworkInfo currentNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
        NetworkInfo otherNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_OTHER_NETWORK_INFO);

        if(currentNetworkInfo.isConnected()){
            Toast.makeText(getApplicationContext(), "Connected", Toast.LENGTH_LONG).show();
        }else{
            Toast.makeText(getApplicationContext(), "Not Connected", Toast.LENGTH_LONG).show();


          }
        }
    };
}
