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!
解决方法
仅当启用或禁用WiFi时才会发送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.
