“缺少调用unregisterReceiver”错误在wifiManager中

Question

我不使用接收器，所以我不注册或取消注册，但是当我多次调用wifiManger方法时，会出现一些错误。这是我的代码：

   WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
    wifiManager.setWifiEnabled(true);
    int res = wifiManager.addNetwork(wc);
    Log.d("WifiPreference", "add Network returned " + res);
    boolean es = wifiManager.saveConfiguration();
    Log.d("WifiPreference", "saveConfiguration returned " + es);
    if (res != -1 && isEdit) {
        wifiManager.removeNetwork(configEdit.networkId);
        wifiManager.saveConfiguration();
        isEdit = false;
    }

非常感谢大家的帮助

泄露了最初在这里注册的IntentReceiver android.net.wifi.WifiManager$1@a517b6e。你错过了打给unregisterReceiver()的电话吗

变化

WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);

至

WifiManager wifiManager = (WifiManager) getApplicationContext.getSystemService(WIFI_SERVICE);

你这样做会泄露记忆
