在清单中声明的​​android – BroadcastReceiver不接收广播

概述我尝试注册一个Wifi BroadcastReceiver以获取WiFi状态,当它改变.但到目前为止,我没有收到广播的运气. <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <receiver android:name=".WifiReceiver" > 我尝试注册一个Wifi broadcastReceiver以获取WiFi状态,当它改变.但到目前为止,我没有收到广播的运气.

<application    androID:icon="@drawable/ic_launcher"    androID:label="@string/app_name" >    <receiver androID:name=".WifiReceiver" >        <intent-filter>            <action androID:name="androID.net.wifi.WifiManager.WIFI_STATE_CHANGED_ACTION" />            <action androID:name="androID.intent.action.PHONE_STATE" />        </intent-filter>    </receiver>    //activity declaration here...</application>

你们知道如何在清单中注册BraodcastReceiver？

我不想在活动中注册,因为当WiFi状态发生变化时,我想监控wifi,无论我的应用程序是否正在运行.

这是我的broadcastReceiver类：

public class WifiReceiver extends broadcastReceiver {    private final String TAG = "WifiReceiver";    @OverrIDe    public voID onReceive(Context context,Intent intent) {        int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE,WifiManager.WIFI_STATE_UNKNowN);        String wifiStateText = "No State";        switch (wifiState) {        case WifiManager.WIFI_STATE_disABliNG:            wifiStateText = "WIFI_STATE_disABliNG";            break;        case WifiManager.WIFI_STATE_Disabled:            wifiStateText = "WIFI_STATE_Disabled";            break;        case WifiManager.WIFI_STATE_ENABliNG:            wifiStateText = "WIFI_STATE_ENABliNG";            break;        case WifiManager.WIFI_STATE_ENABLED:            wifiStateText = "WIFI_STATE_ENABLED";            break;        case WifiManager.WIFI_STATE_UNKNowN:            wifiStateText = "WIFI_STATE_UNKNowN";            break;        default:            break;        }        MyLog.d(TAG,"onReceive broadcast > WiFiState: " + wifiStateText);        MyLog.d(TAG,"onReceive broadcast > Time: " + new Date());    }}

我真的希望得到一些帮助.提前致谢.

解决方法 清单中的接收者应该看起来像这样

<receiver androID:name=".WifiReceiver" >    <intent-filter>       <action androID:name="androID.net.wifi.WIFI_STATE_CHANGED" />    </intent-filter></receiver>

还可能需要以下许可

<uses-permission androID:name="androID.permission.ACCESS_NETWORK_STATE" />
