通过反射发现sendMultipartTextMessage多了一个phoneType的参数，这个参数就是这只用GMS还是CDMA卡发送的。

phoneType获取方法，iTelephony.getActivePhoneType();//1=GSM,2=CDMA

1. try {  
2.            
3.         Class<?> smsManagerClass = null;   
4.         Class[] divideMessagePamas = { String.class };   
5.         Class[] sendMultipartTextMessagePamas = { String.class,String.class, ArrayList.class, ArrayList.class,ArrayList.class, int.class };   
6.         Method divideMessage = null;   
7.         Method sendMultipartTextMessage = null;   
8.         smsManagerClass = Class.forName("android.telephony.SmsManager");   
9.         Method method = smsManagerClass.getMethod("getDefault", new Class[]{});   
10.         Object smsManager = method.invoke(smsManagerClass, new Object[]{});   
11.         divideMessage = smsManagerClass.getMethod("divideMessage",divideMessagePamas);   
12.         sendMultipartTextMessage = smsManagerClass.getMethod("sendMultipartTextMessage", sendMultipartTextMessagePamas);   
13.         ArrayList<String> magArray = (ArrayList<String>) divideMessage.invoke(smsManager, content);   
14.      
15.         sendMultipartTextMessage.invoke(smsManager,phone, "", magArray, null, null,phoneType);  
16.     } catch (IllegalArgumentException e) {  
17.         // TODO Auto-generated catch block  
18.         e.printStackTrace();  
19.     } catch (IllegalAccessException e) {  
20.         // TODO Auto-generated catch block  
21.         e.printStackTrace();  
22.     } catch (InvocationTargetException e) {  
23.         // TODO Auto-generated catch block  
24.         e.printStackTrace();  
25.     } catch (ClassNotFoundException e) {  
26.         // TODO Auto-generated catch block  
27.         e.printStackTrace();  
28.     } catch (SecurityException e) {  
29.         // TODO Auto-generated catch block  
30.         e.printStackTrace();  
31.     } catch (NoSuchMethodException e) {  
32.         // TODO Auto-generated catch block  
33.         e.printStackTrace();

判断手机是否为双卡：

1. public static void initIsDoubleTelephone(Context context){  
2. boolean isDouble = true;  
3. Method method = null;  
4. Object result_0 = null;  
5. Object result_1 = null;  
6. TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);  
7. try {  
8. //只要在反射getSimStateGemini 这个函数时报了错就是单卡手机（这是我自己的经验，不一定全正确）  
9. method = TelephonyManager.class.getMethod("getSimStateGemini",new Class[] { int.class });  
10. //获取SIM卡1  
11. result_0 = method.invoke(tm, new Object[] { new Integer(0) });  
12. //获取SIM卡1  
13. result_1 = method.invoke(tm, new Object[] { new Integer(1) });  
14. } catch (SecurityException e) {  
15. isDouble = false;  
16. e.printStackTrace();  
17. //System.out.println("1_ISSINGLETELEPHONE:"+e.toString());
