简介

Android双卡双待已经越来越普及了，解决双卡双待管理是广大手机开发人员必须得面对的问题，为实现Android平台的双卡双待操作，笔者研究了Android 应用层操作双卡双待的机制。

机制

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：

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 mSimSlots = new ArrayList();
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 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：

public class MTKDualSim extends AbsSim {// 采用MTK方案的类（根据厂家SDK实现不同的接口）
private Object mMSimTelephonyManager = null;
private Object mTelephonyMSim = null;

public MTKDualSim() {
mCallLogExtraField = "simid";

String str1 = SimManager.getModel();
String str2 = SimManager.getManufaturer();
if ((str1 != null) && (str2 != null)) {
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)) {
mCallLogExtraField = "subtype";
}
}
}

@Override
public boolean directCall(String paramString, int paramInt) {
if (SimManager.isSDKVersionMore4_1()) {
Intent localIntent1 = new Intent("android.intent.action.CALL",
Uri.fromParts("tel", paramString, null));
localIntent1.putExtra("simId", paramInt);
localIntent1.putExtra("com.android.phone.extra.slot", paramInt);
localIntent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
getContext().startActivity(localIntent1);
return true;
} catch (Throwable localThrowable1) {
localThrowable1.printStackTrace();
}
} else if (SimManager.isSDKVersionMore4_0()) {
Intent localIntent2 = new Intent(
"com.android.phone.OutgoingCallReceiver");
localIntent2.putExtra("com.android.phone.extra.slot", paramInt);
localIntent2.putExtra("simId", paramInt);
localIntent2.putExtra("com.android.phone.force.slot", true);
localIntent2.setClassName("com.android.phone",
"com.android.phone.OutgoingCallReceiver");
localIntent2.setData(Uri.fromParts("tel", paramString, null));
try {
getContext().sendBroadcast(localIntent2);
return true;
} catch (Throwable localThrowable2) {
localThrowable2.printStackTrace();
}
}

try {
Intent localIntent3 = new Intent();
localIntent3.setAction("out_going_call_to_phone_app");
localIntent3.putExtra("number", paramString);
localIntent3.putExtra("simId", paramInt);
localIntent3.putExtra("com.android.phone.extra.slot", paramInt);
localIntent3.putExtra("launch_from_dialer", 1);
localIntent3.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getContext().sendBroadcast(localIntent3);
return true;
} catch (Throwable localThrowable3) {
localThrowable3.printStackTrace();
}
return false;
}

@Override
public AbsSim detect() {
String imsi = getIMSI(0);
if (imsi != null && !TextUtils.isEmpty(imsi)) {
return this;
}

return super.detect();
}

@Override
public String getSimPhoneNumber(int paramInt) {
Object[] arrayOfObject2 = new Object[1];
try {
Object localObject = getMSimTelephonyManager(paramInt);
arrayOfObject2[0] = Integer.valueOf(paramInt);
String result = (String) ReflecterHelper.invokeMethod(localObject,
"getLine1NumberGemini", arrayOfObject2);
arrayOfObject2 = null;
return result;
} catch (Throwable localThrowable) {
localThrowable.printStackTrace();
}
return "";
}

@Override
public int getDataState(int paramInt) {

try {

return result;
} catch (Throwable localThrowable) {
localThrowable.printStackTrace();
}
arrayOfObject2 = null;
return null;
}

@Override
public int getPhoneState(int paramInt) {
Object localObject = getMSimTelephonyManager(paramInt);
Object[] arrayOfObject2 = new Object[1];

return 0;
}

@Override
public boolean isServiceAvaliable(int paramInt) {

if (localObject == null)
return false;
Object[] arrayOfObject2 = new Object[1];
try {
arrayOfObject2[0] = Integer.valueOf(paramInt);
boolean result = ((Boolean) ReflecterHelper.invokeMethod(
localObject, "isRadioOnGemini", arrayOfObject2))
.booleanValue();
arrayOfObject2 = null;
return result;
} catch (Throwable localThrowable) {
localThrowable.printStackTrace();
}
arrayOfObject2 = null;
return false;
}

@Override
public boolean isSimStateIsReady(int paramInt) {
Object localObject = getMSimTelephonyManager(paramInt);
if (localObject != null) {

return result == 5;
} catch (Throwable localThrowable) {

}

return false;
}

@Override
public int getSimOperator(int paramInt) { // 注意

return 0;
}

@Override
protected Object getITelephonyMSim(int paramInt) {
if (mTelephonyMSim == null)
mTelephonyMSim = ITelephony.Stub.asInterface(ServiceManager
.getService("phone"));
return mTelephonyMSim;
}

@Override

return null;
}
}

再列举一款单卡的方案：

public class SingleSim extends AbsSim implements IDualDetector {// 单卡方案
private final String TAG = getClass().getSimpleName();
private HashMap<String, Byte> mCallLogExtraFields = new SingleSim$1(this);

@Override
public boolean hasSimPhone() {
return false;
}

@Override
public AbsSim detect() {// 根据某些字段判是否为双卡（有可能误判）
if (mIsDualSimPhone)
return null;

Cursor localSafeCursor = null;
String[] arrayOfString;
try {
localSafeCursor = SimManager
.getInstance()
.getContext()
.getContentResolver()
.query(CallLog.Calls.CONTENT_URI, null, null, null,
"_id limit 0,1");

if (localSafeCursor != null && localSafeCursor.moveToFirst()) {
arrayOfString = localSafeCursor.getColumnNames();

for (int i = 0; i < arrayOfString.length; i++) {
String str = arrayOfString[i];
if (mCallLogExtraFields.containsKey(str.toLowerCase())) {
mIsDualSimPhone = true;
mCallLogExtraField = str;
}
}

}
} catch (Exception e) {
e.printStackTrace();
}

return this;
}

@Override
public boolean isDualSimPhone() {
return mIsDualSimPhone;
}

@Override
public int getSimSlotNum() {
return 1;
}

@Override
public String getSimPhoneNumber(int paramInt) {
return ((TelephonyManager) getMSimTelephonyManager(0)).getLine1Number();
}

@Override
public int getDataState(int paramInt) {
return ((TelephonyManager) getMSimTelephonyManager(0)).getDataState();
}

@Override
public String getIMSI(int paramInt) {
return ((TelephonyManager) getMSimTelephonyManager(0)).getDeviceId();
}

@Override
public String getIMSI(int paramInt, Context paramContext) {
return ((TelephonyManager) getMSimTelephonyManager(0))
.getSubscriberId();
}

@Override
public int getPhoneState(int paramInt) {
return ((TelephonyManager) getMSimTelephonyManager(0)).getCallState();
}

@Override
public boolean isServiceAvaliable(int paramInt) {
ITelephony localITelephony = (ITelephony) getITelephonyMSim(0);
if (localITelephony == null)
return false;
try {
boolean bool = localITelephony.isRadioOn();
return bool;
} catch (Throwable localThrowable) {
localThrowable.printStackTrace();
}
return false;
}

@Override
public boolean isSimStateIsReady(int paramInt) {
return ((TelephonyManager) getMSimTelephonyManager(0)).getSimState() == 5;
}

@Override
public int getSimOperator(int paramInt) {
TelephonyManager localTelephonyManager = (TelephonyManager) getMSimTelephonyManager(paramInt);
return Integer.parseInt(localTelephonyManager.getSimOperator());
}

@Override
protected Object getITelephonyMSim(int paramInt) {
return SimManager.getInstance().getITelephonyByPhone();
}

@Override
protected Object getMSimTelephonyManager(int paramInt) {
return SimManager.getInstance().getTelephonyManagerByPhone();
}
}

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。
