set sdk home windows ->property->android . So it is.

自帶的JoinMe軟件是有撥號功能

把N600連在電腦上,在手機上       選"設置"____ "應用" ____"開發"把"USB調試"打開,就能用了

在進行android-sdk-windows中進行 update all時， 報錯 folder failed to be renamed or moved 2010-05-10 14:56 在進行android-sdk-windows中進行 update all時， 報錯 folder failed to be renamed or moved...,goole了一下，有外國網友解決辦法如下: 1, 復制 tools目錄 為一個新的目錄 tools-copy ,此時在android-sdk-windows 目錄下有兩個目錄 tools 和 tools-copy 2, 在tools-copy目錄運行 android.bat ，這樣就可以正常 update all 了 3，之后，關閉 sdk, 4, 在 android-sdk-windows 目錄運行 SDK Setup.exe， 就可以了

scrollView.scrollTo(0,0);

 Context context = getApplicationContext();
        CharSequence text = "have a toast thank you ,you've got it!";
        int duration = Toast.LENGTH_SHORT;

        Toast toast = Toast.makeText(context, text, duration);
        toast.show();

1. Get a reference to the NotificationManager:

   String ns = Context.NOTIFICATION_SERVICE;
   
       NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

2. Instantiate the Notification:

   int icon = R.drawable.notification_icon;
   
       CharSequence tickerText = "Hello";
   
       long when = System.currentTimeMillis();
   
       
   
       Notification notification = new Notification(icon, tickerText, when);

3. Define the Notification's expanded message and Intent:

   Context context = getApplicationContext();
   
       CharSequence contentTitle = "My notification";
   
       CharSequence contentText = "Hello World!";
   
       Intent notificationIntent = new Intent(this, MyClass.class);
   
       PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
   
       
   
       notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

4. Pass the Notification to the NotificationManager:

   private static final int HELLO_ID = 1;
   
       
   
       mNotificationManager.notify(HELLO_ID, notification);

   That's it. Your user has now been notified.

發送短信相當的簡單，只需要幾行代碼，如下：

import android.telephony.gsm.SmsManager;
import android.app.PendingIntent;
......
SmsManager sms = SmsManager.getDefault();
PendingIntent pi = PendingIntent.getBroadcast(this, 0, new Intent(), 0);
sms.sendTextMessage(phoneNumber, null, MsgStr, pi, null);

其中參數phoneNumber和MsgStr均是String類型，表示接收方的電話號碼和短信內容

接收短信相對而言麻煩一些，需要使用全局的接收類BroadcastReceiver，完整代碼如下：

package com.hello.db;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.gsm.SmsMessage;
import android.widget.Toast;

public class MessageDemo extends BroadcastReceiver {
    private static final String strACT = "android.provider.Telephony.SMS_RECEIVED";
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(strACT)) {
StringBuilder sb = new StringBuilder();
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
SmsMessage[] msg = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
msg[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
for (SmsMessage currMsg : msg) {
sb.append("From:");
sb.append(currMsg.getDisplayOriginatingAddress());
sb.append("\nMessage:");
sb.append(currMsg.getDisplayMessageBody());
}
}
Toast.makeText(context, sb.toString(), Toast.LENGTH_LONG).show();
Intent i = new Intent(context, DBDemo.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
}

此處的接收是收到消息時，彈出一個Toast提示，在此基礎上稍做修改也可以實現將收到的消息放入文本框從而展示出來。注意最后必須將控制權交還給上一個Activity，不然程序會出錯。

好了，收發短信的代碼都有了，下面需要配置權限，只有程序擁有了權限，這些功能才能真正被使用
修改AndroidManifest.xml，在Activity下添加receiver節點：
<receiver android:name="MessageDemo">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
隨后在application下添加節點：
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
