我需要扫描未知SSID列表,并使用几个预定义密码登录接入点。如果成功,则继续下一个任务。如果失败,则尝试登录下一个SSID。
我会尽可能多地注册,看看哪一个是有效的:
receiverWifi = new WifiReceiver();
registerReceiver(receiverWifi, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
registerReceiver(receiverWifi, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION)
我在我的register.class开始时初始化了两个公共接收变量
public RegisterReceiver rReceiver;
public ConvertAddressToLatLongReceiver catllReceiver;
然后在onCreate()中,我将它们定义为
rReceiver = new RegisterReceiver(new Handler());
rReceiver.setReceiver(this);
catllReceiver = new ConvertAddressToLatLongReceiver(new Handler());
catllRe
我得到以下错误:
“您是否错过了取消注册接收方的呼叫”

我有一个Fragment Tabs寻呼机,用的是sherlockFragment,我需要在里面搜索其他蓝牙设备。但我不能registerReceiver,因为它是必要的。我得到以下错误:未为类型Fragment_Bluetooth定义方法registerReceiver(BroadcastReceiver,IntentFilter)。我想知道我是否应该在另一个作用域中使用registerReceiver?在哪里,怎么做到的?下面是我的代码:

final TileWriter tileWriter = new TileWr
