在我的应用中,如果连接了网络更改,我需要重新启动服务。目前它只能以一种方式工作(wifi到移动数据),但它不能以其他方式工作(移动数据到wifi。)为什么会这样?是因为我没有在我的广播接收器中获得android.net.wifi.WIFI_STATE_CHANGED
或者可能是错位的许可?
感谢您的帮助。
代码: 收件人的清单条目:
<receiver
android:name="LiveForever"
android:label="NetworkChangeReceiver" >
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
<action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
</intent-filter>
</receiver>
接收器本身:
public static final int TYPE_WIFI = 1;
public static final int TYPE_MOBILE = 2;
public static final int TYPE_NOT_CONNECTED = 0;
public static final String PREFS_NAME = "cakecloudpreferences";
@Override
public void onReceive(Context context, Intent intent) {
SharedPreferences settings = context.getSharedPreferences(PREFS_NAME, 0);
if (getConnectivityStatus(context)!=0&&!settings.getBoolean("osmframerunning",false)) {
context.stopService(new Intent(context, OSMFrame.class));
settings.edit().putBoolean("osmframerunning",false).commit();
Intent frameintent = new Intent(context,OSMFrame.class);
frameintent.putExtra("username",settings.getString("usr",""));
frameintent.putExtra("password",settings.getString("pswd",""));
frameintent.putExtra("uid",settings.getString("uid",""));
context.startService(frameintent);
Log.i("CCLiveForever","LiveForever Triggered, OSMFrame restarted.");
}
}
public int getConnectivityStatus(Context context) {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (null != activeNetwork) {
if(activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) return TYPE_WIFI;
if(activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) return TYPE_MOBILE;
}
return TYPE_NOT_CONNECTED;
}

再次,谢谢!
答案 0 :(得分:13)
android.net.wifi.WIFI_STATE_CHANGED
。如果您希望在连接到WiFi网络或从WiFi网络断开连接时接收广播事件,则还需要捕获android.net.wifi.STATE_CHANGE
。
