在我的应用程序中,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或者可能是错位的权限?
谢谢你的帮助.
码:
接收器的清单条目:
<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; }
我列出的相关权限:
> android.permission.ACCESS_WIFI_STATE
> android.permission.ACCESS_NETWORK_STATE
> android.permission.INTERNET
再次谢谢你!
