我有一个适用于 Android 6 的应用程序，但在 Android 7 上冻结。我所拥有的只是 LG 添加的 ConnectSDK（http://www.svlconnectsdk.com/docs/1-6-0/android/）。一旦我在 DiscoveryManager 的对象上调用 start，应用程序就会冻结。我得到以下堆栈跟踪：

10-26 13:32:51.678：W/System(7569)：ClassLoader 引用未知路径：/data/app/com.testconnectsdk.test-1/lib/arm64 10-26 13:32:51.774：W/System。错误（7569）：java.net.SocketException：套接字关闭 10-26 13:32:51.774：W/System.err（7569）：在 java.net.PlainDatagramSocketImpl.receive0（本机方法）10-26 13:32： 51.774: W/System.err(7569): 在 java.net.AbstractPlainDatagramSocketImpl.receive(AbstractPlainDatagramSocketImpl.java:147) 10-26 13:32:51.774: W/System.err(7569): 在 java.net.DatagramSocket .receive(DatagramSocket.java:808) 10-26 13:32:51.774: W/System.err(7569): 在 com.connectsdk.discovery.provider.ssdp.SSDPClient.multicastReceive(SSDPClient.java:109) 10- 26 13:32:51.774：W/System.err(7569)：在 com.connectsdk.discovery.provider.SSDPDiscoveryProvider$2。运行（SSDPDiscoveryProvider.java:271）10-26 13:32:51.774：W/System.err（7569）：在 java.lang.Thread.run（Thread.java:761）

代码很简单：

public class MainActivity extends Activity implements DiscoveryManagerListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        DiscoveryManager.init(getApplicationContext(), null);
        final DiscoveryManager dm = DiscoveryManager.getInstance();

        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                dm.addListener(MainActivity.this);
            }
        }, 2000);

        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                dm.start();
            }
        }, 4000);



        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                Intent i = new Intent(MainActivity.this, OtherActivity.class);
                startActivity(i);
            }
        }, 6000);

    }

    private static final String TAG = MainActivity.class.getName();

    @Override
    public void onDeviceAdded(DiscoveryManager manager, ConnectableDevice device) {
        // TODO Auto-generated method stub
        Log.d(TAG, "onDeviceAdded");

    }

    @Override
    public void onDeviceUpdated(DiscoveryManager manager, ConnectableDevice device) {
        // TODO Auto-generated method stub
        Log.d(TAG, "onDeviceUpdated");
    }

    @Override
    public void onDeviceRemoved(DiscoveryManager manager, ConnectableDevice device) {
        // TODO Auto-generated method stub
        Log.d(TAG, "onDeviceRemoved");
    }

    @Override
    public void onDiscoveryFailed(DiscoveryManager manager, ServiceCommandError error) {
        // TODO Auto-generated method stub
        Log.d(TAG, "onDiscoveryFailed");
    }
}

知道为什么会崩溃吗？粘贴我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.testconnectsdk.test"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="15"
        android:targetSdkVersion="15" />

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE"/>
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="OtherActivity"></activity>
    </application>

</manifest>

请帮忙。非常需要它。谢谢
