在我的應用程序中,如果連接了網絡更改,我需要重新啓動服務。目前它只適用於一種方式(無線網絡到移動數據),但它不能以另一種方式工作(移動數據到無線網絡)。這是爲什麼?是因爲我的廣播接收器沒有收到android.net.wifi.WIFI_STATE_CHANGED
,或者可能是錯誤的許可?android.net.wifi.WIFI_STATE_CHANGED未被廣播
感謝您的任何幫助。
代碼:
<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>
接收機本身:我列出
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;
}
相關權限:
- android.permission.ACCESS_WIFI_STATE
- 接收機 Manifest條目android.permi ssion.ACCESS_NETWORK_STATE
- android.permission.INTERNET對
再次感謝您!
謝謝!有效! –
