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(fā)"把"USB調(diào)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(wǎng)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

IQ測試

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(fā)送短信相當?shù)暮唵危恍枰獛仔写a，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(shù)phoneNumber和MsgStr均是String類型，表示接收方的電話號碼和短信內(nèi)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(xiàn)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(fā)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(jié)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(jié)點：
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
