Android 2.3发短信详细流程(2)

3. 第二阶段：IccSmsInterfaceManagerProxy.java(frameworks/base/telephony/java/com/android/internal/telephony/IccSmsInterfaceManagerProxy)

我们看IccSmsInterfaceManagerProxy的sendText()方法核心代码：

view plaincopy to clipboardprint?private IccSmsInterfaceManager mIccSmsInterfaceManager; 
...... 
public void sendText(String destAddr, String scAddr, 
            String text, PendingIntent sentIntent, PendingIntent deliveryIntent) { 
        mIccSmsInterfaceManager.sendText(destAddr, scAddr, text, sentIntent, deliveryIntent); 
    } 
private IccSmsInterfaceManager mIccSmsInterfaceManager;
......
public void sendText(String destAddr, String scAddr,
            String text, PendingIntent sentIntent, PendingIntent deliveryIntent) {
        mIccSmsInterfaceManager.sendText(destAddr, scAddr, text, sentIntent, deliveryIntent);
    }
继续调用，此时调用的是IccSmsInterfaceManager对象的sendText()方法，那IccSmsInterfaceManager是什么玩意？？

4. 第三阶段：IccSmsInterfaceManager.java(frameworks/base/telephony/java/com/android/internal/telephony/IccSmsInterfaceManager.java)

从代码看出IccSmsInterfaceManager是一个继承了ISms.Stub的抽象类，相关核心代码如下：

view plaincopy to clipboardprint?protected SMSDispatcher mDispatcher; 
public void sendText(String destAddr, String scAddr, 
            String text, PendingIntent sentIntent, PendingIntent deliveryIntent) { 
        mPhone.getContext().enforceCallingPermission( 
                "android.permission.SEND_SMS", 
                "Sending SMS message"); 
        if (Log.isLoggable("SMS", Log.VERBOSE)) { 
            log("sendText: destAddr=" + destAddr + " scAddr=" + scAddr + 
                " text='"+ text + "' sentIntent=" + 
                sentIntent + " deliveryIntent=" + deliveryIntent); 
        } 
        mDispatcher.sendText(destAddr, scAddr, text, sentIntent, deliveryIntent); 
    } 
protected SMSDispatcher mDispatcher;
