解决 Android 双卡双待识别

Android开发的问题 其实很好狠。今天看到一篇解决android 机型 双卡 管理的问题。看到一篇比较好的文章就转载过来了 = =

获取基于ITelephony接口实现phone应用中的“phone服务”，通过TelephonyManager接口获取不同的卡（GSMPhone /CDMAPhone）进行不同的操作（拨号、接通、挂断、保持通话等）。

Android平台是一个多样型的平台，不同的手机获取ITelephony接口不同，用一种方法实现双卡双待管理是不可取的。那怎么办呢？只有针对不同的手机分析出一套管理的方案，该方案实现难度大，因为需要各个厂家的SDK的资料。为了实现该功能，笔者做了大量工作，整合各个厂家的SDK的资料。

实现

为了更好的管理双卡双待的问题，新建一个双卡双待模块静态库，其它项目引用便是，项目如图：

效果如图：

AbsSim是抽象类，负责实现手机操作的类。不同的厂家继承该类实现各自的接口。AbsSim信息如下：

 public abstract class AbsSim implements IDualDetector { //抽象基类
     protected final String TAG = getClass().getSimpleName();
     protected ArrayList<SimSlot> mSimSlots = new ArrayList<SimSlot>();
     protected boolean mIsDualSimPhone = false;
     protected String mCallLogExtraField = "";

     public abstract String getSimPhoneNumber(int paramInt); // 返回手机号码

     public abstract int getDataState(int paramInt);// 返回数据状态

     public abstract String getIMSI(int paramInt);// 返回手机标识

     public abstract String getIMSI(int paramInt, Context paramContext);// 返回手机标识

     public abstract int getPhoneState(int paramInt);// 返回手机状态

     public abstract boolean isServiceAvaliable(int paramInt);// 服务是否可用

     public abstract boolean isSimStateIsReady(int paramInt);// 卡是否在使用

     public abstract int getSimOperator(int paramInt);// 服务商（电信、移动、联通）

     protected abstract Object getITelephonyMSim(int paramInt);// 获取操作接口

     protected abstract Object getMSimTelephonyManager(int paramInt);// 获取操作接口

     @Override
     public AbsSim detect() { // 根据手机信息匹配
         if ((getITelephonyMSim(0) != null) && (getITelephonyMSim(1) != null)
         // && (getmMSimSmsManager(0) != null)
         // && (getmMSimSmsManager(1) != null)
         // && (detectSms(paramContext, paramBoolean))
         // && (detectCallLog(paramContext, paramBoolean))
         )
             return this;
         return null;
     }

     public boolean directCall(String paramString, int paramInt) { // 拨打电话（根据不同卡拨打电话）
         Intent localIntent = new Intent("android.intent.action.CALL",
                 Uri.fromParts("tel", paramString, null));
         localIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         try {
             getContext().startActivity(localIntent);
             return true;
         } catch (Throwable localThrowable) {
             localThrowable.printStackTrace();
         }
         return false;
     }

     protected boolean detectCallLog() { // 通过通话记录信息匹配
         return false;
     }

     protected boolean detectSms() {// 通过短信记录信息匹配
         return false;
     }

     protected Context getContext() { // 返回句柄
         return SimManager.getInstance().getContext();
     }

     protected int getSimSlotNum() { // 返回插槽个数(默认2)
         return 2;
     }

     public void init() { // 初始化
         for (int i = 0; i < getSimSlotNum(); i++) {
             try {
                 String imsi = getIMSI(i);
                 boolean isUsing = isSimStateIsReady(i);
                 if (imsi != null || isUsing) {
                     if (imsi == null || hasSimSlotByIMSI(imsi))
                         continue;

                     SimSlot simSlot = new SimSlot();
                     mSimSlots.add(simSlot);
                     simSlot.setUsing(isUsing);
                     simSlot.setIMSI(imsi);
                     simSlot.setSimOperator(getSimOperator(i));
                 }
             } catch (Exception e) {
                 e.printStackTrace();
             }
         }
     }

     public boolean hasSimPhone() {// 是否有sd卡在使用
         if (mSimSlots.isEmpty())
             return false;

         for (SimSlot simslot : mSimSlots) {
             if (simslot.isUsing())
                 return true;
         }

         return false;
     }

     public boolean isDualSimPhone() {// 是否为双卡
         if (getSimSlots().isEmpty() || getSimSlots().size() < 2)
             return false;

         for (SimSlot simSlot : getSimSlots()) {
             if (!simSlot.isUsing())
                 return false;
         }

         return true;
     }

     public ArrayList<SimSlot> getSimSlots() { // 返回已确认的卡
         return mSimSlots;
     }

     protected boolean delSimSlotByIMSI(String imsi) { // 删除相同的卡的信息
         for (SimSlot simSlot : getSimSlots()) {
             if (simSlot.getIMSI() != null && simSlot.getIMSI().equals(imsi)) {
                 getSimSlots().remove(simSlot);
             }
         }

         return false;
     }

     protected boolean hasSimSlotByIMSI(String imsi) {
         for (SimSlot simSlot : getSimSlots()) {
             if (simSlot.getIMSI() != null && simSlot.getIMSI().equals(imsi)) {
                 return true;
             }
         }

         return false;
     }
 }

现在列举一款实现MTK方案：

             String str3 = str1.toLowerCase();
             String str4 = str2.toLowerCase();
             if ((str4.indexOf("huawei") > -1) && (str3.indexOf("h30-t00") > -1))
                 mCallLogExtraField = "subscription";
             if ((str4.indexOf("hisense") > -1)
                     && (str3.indexOf("hs-u970") > -1)) {

             }
         }
     }

     @Override

                 return true;
             } catch (Throwable localThrowable1) {

         } else if (SimManager.isSDKVersionMore4_0()) {

总结

利用java 反射机制操作Android隐藏的类，很好的解决了双卡双待的问题。
Java反射是Java被视为动态（或准动态）语言的一个关键性质。这个机制允许程序在运行时透过Reflection APIs取得任何一个已知名称的class的内部信息，包括其modifiers（诸如public, static 等）、superclass（例如Object）、实现之interfaces（例如Cloneable），也包括fields和methods的所有信息，并可于运行时改变fields内容或唤起methods。
