Android 解决双卡双待手机解析短信异常

开发中，难免会遇到各种各样的适配问题，尤其是经过深度修改定制过的系统，有的无论是软硬件上都有很大的区别,这里不得不提到一种奇葩的机型，没错，那就是双卡双待的手机（比如XT800， A60， S8600 ， Lenovo A750，中兴V889D等）.由于是双SIM卡，而且两个卡槽支持的运营商或者网络制式不一定相同,比如一个卡槽支持WCDMA,另一个却只支持GSM ,导致用正常方法解析短信很容易遇到异常

想深入了解双卡双待手机短信发送与接收流程的话，请看我之前关于 MMS的分析：

这里先看下解决方案,这里需要以反射的方式解析不同类型的短信，并且对于不同机型，需对应地进行调整适配:

获取短信信息，注意：为解决双卡双待手机解析短信异常问题，使用Java反射机制，优先解析GSM类型的短信，假如解析失败才按CDMA类型的短信进行解析）

public static SmsMessage[] getSmsMessage(Intent intent) {         SmsMessage[] msgs = null;         Object messages[] = (Object[]) intent.getSerializableExtra(pdus);         int len = 0;         if (null != messages && (len = messages.length) > 0) {             msgs = new SmsMessage[len];             try {                 for (int i = 0; i < len; i++) {                     SmsMessage message = null;                     if (GSM.equals(intent.getStringExtra(from))) { // 适配MOTO XT800双卡双待手机                         message = createFromPduGsm((byte[]) messages[i]);                     } else if (CDMA.equals(intent.getStringExtra(from))) { // 适配MOTO XT800双卡双待手机                         message = createFromPduCdma((byte[]) messages[i]);                     } else {                         message = SmsMessage.createFromPdu((byte[]) messages[i]); // 系统默认的解析短信方式                     }                     if (null == message) { // 解决双卡双待类型手机解析短信异常问题                         message = createFromPduGsm((byte[]) messages[i]);                         if (null == message) {                             message = createFromPduCdma((byte[]) messages[i]);                         }                     }                     if (null != message) {                         msgs[i] = message;                     }                 }             } catch (Exception e) {                 e.printStackTrace();                 msgs = getSmsMessageByReflect(intent); // 解决双卡双待手机解析短信异常问题             } catch (Error er) {                 er.printStackTrace();                 msgs = getSmsMessageByReflect(intent); // 解决双卡双待手机解析短信异常问题             }         }         return msgs;     }

反射方式获取短信

通过Java反射机制解析GSM类型的短信:

private static SmsMessage createFromPduGsm(byte[] pdu) throws SecurityException, IllegalArgumentException, ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException {         return createFromPdu(pdu, com.android.internal.telephony.gsm.SmsMessage);     }

解析CDMA类型的短信

1 2 3

private static SmsMessage createFromPduCdma(byte[] pdu) throws SecurityException, IllegalArgumentException, ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException {     return createFromPdu(pdu, com.android.internal.telephony.cdma.SmsMessage); }

解析GSM或者CDMA类型的短信

private static SmsMessage createFromPdu(byte[] pdu, String className) throws ClassNotFoundException, SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException, InstantiationException {         Class<!--?--> clazz = Class.forName(className);         Object object = clazz.getMethod(createFromPdu, byte[].class).invoke(clazz.newInstance(), pdu);         if (null != object) {             Constructor<!--?--> constructor = SmsMessage.class.getDeclaredConstructor(Class.forName(com.android.internal.telephony.SmsMessageBase));             constructor.setAccessible(true);             return (SmsMessage) constructor.newInstance(object);         } else {             return null;         }     }
