04-08 00:17:52.016: DEBUG/SntpClient(67): request time failed: java.net.SocketException: Address family not supported by protocol

alarm.java

public class Alarm extends Activity 
{ 
    DateFormat fmtDateAndTime=DateFormat.getDateTimeInstance(); 
    TextView dateAndTimeLabel; 
    Calendar dateAndTime=Calendar.getInstance(); 
    Button Alarm; 
    Alarm instance; 

    Toast mToast=null; 
    DatePickerDialog.OnDateSetListener d=new DatePickerDialog.OnDateSetListener() { 
     public void onDateSet(DatePicker view, int year, int monthOfYear, 
       int dayOfMonth) { 
      dateAndTime.set(Calendar.YEAR, year); 
      dateAndTime.set(Calendar.MONTH, monthOfYear); 
      dateAndTime.set(Calendar.DAY_OF_MONTH, dayOfMonth);     
     } 
    }; 
TimePickerDialog.OnTimeSetListener t=new TimePickerDialog.OnTimeSetListener() { 
    public void onTimeSet(TimePicker view, int hourOfDay,int minute) { 
     dateAndTime.set(Calendar.HOUR_OF_DAY, hourOfDay); 
     dateAndTime.set(Calendar.MINUTE, minute);   
     view.setCurrentHour(Calendar.HOUR_OF_DAY); 

    } 
}; 
@Override 
public void onCreate(Bundle icicle) {  
    super.onCreate(icicle); 
    setContentView(R.layout.main); 
    instance = this; 
    Button btn=(Button)findViewById(R.id.Date); 
    Alarm = (Button)findViewById(R.id.Alarm); 
    btn.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      new DatePickerDialog(Alarm.this,d, 
        dateAndTime.get(Calendar.YEAR), 
        dateAndTime.get(Calendar.MONTH), 
        dateAndTime.get(Calendar.DAY_OF_MONTH)).show();    } 
    }); 
    btn=(Button)findViewById(R.id.time); 
    btn.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      new TimePickerDialog(Alarm.this,t, 
        dateAndTime.get(Calendar.HOUR_OF_DAY), 
        dateAndTime.get(Calendar.MINUTE), 
        true).show(); 
      } 
    }); 

    Alarm.setOnClickListener(new View.OnClickListener(){ 
     public void onClick(View v) 
     { 
      Intent intent = new Intent(instance, OnetimeAlarmReceiver.class); 
      PendingIntent sender = PendingIntent.getBroadcast(instance,0, intent, 0); 
      dateAndTime.add(Calendar.SECOND, 5); 
      long timeSet = dateAndTime.getTimeInMillis();    
      AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE); 
      am.set(AlarmManager.RTC_WAKEUP, timeSet, sender); 

      if (mToast != null) { 
       mToast.cancel(); 
      } 
      mToast = Toast.makeText(instance, "Alarm Set for " + dateAndTime.getTime(), 
        Toast.LENGTH_LONG); 
      mToast.show(); 
     } 
    }); 
} 
}

OnetimeAlarmReceiver.java

public class OnetimeAlarmReceiver extends Service{ 

    @Override 
    public void onCreate() { 
     super.onCreate(); 
     Builder builder = new Builder(this); 
     builder.setMessage("Started").create().show(); 
     Log.d("Value ", "Service Started"); 
    } 
    @Override 
    public void onStart(Intent intent, int startId) { 
     super.onStart(intent, startId); 
     Builder builder = new Builder(this); 
     builder.setMessage("Started").create().show(); 
     Log.d("Value ", "Service Started"); 
    } 
    @Override 
    public IBinder onBind(Intent intent) { 
     // TODO Auto-generated method stub 
     return null; 
    } 
}

清单：

<application android:icon="@drawable/icon" android:label="@string/app_name"> 
    <activity android:name=".Alarm" 
       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 =".OnetimeAlarmReceiver">

在那里我做了错误任何一个可以帮助谢谢

添加权限，服务于你的清单。使用它它运行没有错误。

<uses-sdk android:minSdkVersion="4" /> 

<uses-permission android:name="com.android.alarm.permission.SET_ALARM" > 
</uses-permission> 

<application 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" > 
    <activity 
     android:name=".Alarm" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

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

    <receiver 
     android:name=".OnetimeAlarmReceiver" 
     android:process=":remote" /> 
</application>
