我想提一下,这是复制副本的副本,我从来没有得到任何答案。我已经有这个问题超过2个月了,同时我不得不继续这个项目而忽略了问题但是,如果不解决这个问题,我就无法继续前进。

所以,我有一个UDP连接,如下所示:

final Runnable r = new Runnable() {
         public void run() {


    try {
     if(host != null){
         byte [] data = "lista_categorii".getBytes();
         byte[] buf = new byte[1024];

         host = InetAddress.getByName(//IPGOESHERE;
         socket = new DatagramSocket(55901);


         DatagramPacket packet = new DatagramPacket(data, data.length, host, 55901);             
         socket.send(packet);
         socket.setSoTimeout(1000);


         /*
         packet = new DatagramPacket(buf, buf.length);
         socket.receive(packet);    
         //String modifiedSentence = new String(packet.getData()); 
         modifiedSentence = new String(packet.getData(), 0, packet.getLength());*/

     }

} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
finally{
    if(socket != null){
        socket.close();
    }
}
         }
     };

一切正常,直到我按下调用我刚刚链接的代码的按钮。一旦我这样做,我得到了这个地狱产生的错误:

07-04 15:11:44.199: E/DatabaseUtils(2344): Writing exception to parcel

我的Android Manifest看起来像这样(我相信人们会这么问......):

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

    <uses-sdk
        android:minSdkVersion="17"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="INTERACT_ACROSS_USERS_FULL" />
    <uses-permission android:name="INTERACT_ACROSS_USERS" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar" >
        <activity
            android:name="com.restaurant.main.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="com.restaurant.main.Categories" >
        </activity>
        <activity android:name="com.restaurant.main.Produse" >
        </activity>
        <activity android:name="com.restaurant.main.ScreenComanda" >
        </activity>
        <activity android:name="com.restaurant.main.OfertaZilei" >
        </activity>
        <activity android:name="com.restaurant.main.CeAmComandat" >
        </activity>
    </application>

</manifest>

如果需要任何其他信息,请告诉我,我会马上和你在一起。

注意:我在三星Galaxy S3上测试它。
