Question

我为android创建了一个jar文件（库），它可以启动wifi并注册广播接收器，当活动停止库用户可以调用该函数并取消注册Receiver时，我已经提供了一个函数。

在库类构造函数中wifi broadcastReceiver注册如下。

broadcastReceiver = new WiFiScanReceiver(mWifiManager,mDesiredActRdrSSID);
        mActivity.registerReceiver(broadcastReceiver, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
        broadcastReceiver.registerActRdrFoundEvent(this);

但是当我调用包含以下代码的断开连接函数时。

public void disconnect()
    {
        try
        {
        Log.e(TAG, "Disconnect....***");
        if(broadcastReceiver!= null)
            mActivity.unregisterReceiver(broadcastReceiver);
        broadcastReceiver = null;
        }
        catch(Exception e)
        {

        }
    }

但是当活动结束时它也会出错。

任何人都可以帮助我吗？我做错了什么？这个函数在“.jar”文件中提供。

你错过了对unregisterreceiver（）的调用吗？
