Android 解决双卡双待的问题 mtk，展讯，高通

目前国内对于双卡智能手机的需求还是很大的，各种复杂的业务会涉及到双卡模块；而android标准的api又不提供对双卡的支持。导致国内双卡模块标准混乱，各个厂商各玩各的。目前我知道的双卡解决方案就有：mtk，展讯，高通，broadcom等。

 

由于公司业务需要，必须要对双卡手机获取各自的imei，imsi，所以也做了一些研究：

 

首先是最为应用广泛的mtk平台，国内山寨手机以及一些低端品牌双卡都是做的mtk的双卡解决方案

 

 

private static void initMtkDoubleSim() {

try {

TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);

Class<?> c = Class.forName("com.android.internal.telephony.Phone");

Field fields1 = c.getField("GEMINI_SIM_1");

fields1.setAccessible(true);

simId_1 = (Integer) fields1.get(null);

Field fields2 = c.getField("GEMINI_SIM_2");

fields2.setAccessible(true);

simId_2 = (Integer) fields2.get(null);

Method m = TelephonyManager.class.getDeclaredMethod(

"getSubscriberIdGemini", int.class);

imsi_1 = (String) m.invoke(tm, simId_1);

imsi_2 = (String) m.invoke(tm, simId_2);

Method m1 = TelephonyManager.class.getDeclaredMethod(

"getDeviceIdGemini", int.class);

imei_1 = (String) m1.invoke(tm, simId_1);

imei_2 = (String) m1.invoke(tm, simId_2);

Method mx = TelephonyManager.class.getDeclaredMethod(

"getPhoneTypeGemini", int.class);

phoneType_1 = (Integer) mx.invoke(tm, simId_1);

phoneType_2 = (Integer) mx.invoke(tm, simId_2);

if (TextUtils.isEmpty(imsi_1) && (!TextUtils.isEmpty(imsi_2))) {

defaultImsi = imsi_2;

}

if (TextUtils.isEmpty(imsi_2) && (!TextUtils.isEmpty(imsi_1))) {

defaultImsi = imsi_1;

}

} catch (Exception e) {

isMtkDoubleSim = false;

return;

}

isMtkDoubleSim = true;

}

 

 

 可见，在TelephonyManager中提供了**Gemini的方法，可以用反射很方便地获取到相应的信息。

 

还有

private static void initMtkSecondDoubleSim() {

try {

TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);

Class<?> c = Class.forName("com.android.internal.telephony.Phone");

Field fields1 = c.getField("GEMINI_SIM_1");

fields1.setAccessible(true);

simId_1 = (Integer) fields1.get(null);

Field fields2 = c.getField("GEMINI_SIM_2");

fields2.setAccessible(true);

simId_2 = (Integer) fields2.get(null);

Method mx = TelephonyManager.class.getMethod("getDefault",

int.class);

TelephonyManager tm1 = (TelephonyManager) mx.invoke(tm, simId_1);

TelephonyManager tm2 = (TelephonyManager) mx.invoke(tm, simId_2);

imsi_1 = tm1.getSubscriberId();

imsi_2 = tm2.getSubscriberId();

imei_1 = tm1.getDeviceId();

imei_2 = tm2.getDeviceId();

phoneType_1 = tm1.getPhoneType();

phoneType_2 = tm2.getPhoneType();

if (TextUtils.isEmpty(imsi_1) && (!TextUtils.isEmpty(imsi_2))) {

defaultImsi = imsi_2;

}

if (TextUtils.isEmpty(imsi_2) && (!TextUtils.isEmpty(imsi_1))) {

defaultImsi = imsi_1;

}

} catch (Exception e) {

isMtkSecondDoubleSim = false;

return;

}

isMtkSecondDoubleSim = true;

}

 

 看样子有似乎也是属于mtk平台的解决方案，因为都有GEMINI_SIM_1属性,这种双卡方案只在联想278t上发现过；有两个TelephonyManager实例，根据getDefault方法获取

下面是展讯平台的（貌似市面上手机不多啊）：

private static void initSpreadDoubleSim() {

try {

Class<?> c = Class

.forName("com.android.internal.telephony.PhoneFactory");

Method m = c.getMethod("getServiceName", String.class, int.class);

spreadTmService = (String) m

.invoke(c, Context.TELEPHONY_SERVICE, 1);

TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);

imsi_1 = tm.getSubscriberId();

imei_1 = tm.getDeviceId();

phoneType_1 = tm.getPhoneType();

TelephonyManager tm1 = (TelephonyManager) mContext.getSystemService(spreadTmService);

imsi_2 = tm1.getSubscriberId();

imei_2 = tm1.getDeviceId();

phoneType_2 = tm1.getPhoneType();

if (TextUtils.isEmpty(imsi_1) && (!TextUtils.isEmpty(imsi_2))) {

defaultImsi = imsi_2;

}

if (TextUtils.isEmpty(imsi_2) && (!TextUtils.isEmpty(imsi_1))) {

defaultImsi = imsi_1;

}

} catch (Exception e) {

isSpreadDoubleSim = false;

return;

}

isSpreadDoubleSim = true;

}

 

 这个没有展讯sdk的话还是很难找的吧？

下面是高通的：（貌似高通做的不咋的有些接口没有双卡实现啊）

public static void initQualcommDoubleSim() {
try {
TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> cx = Class
.forName("android.telephony.MSimTelephonyManager");
Object obj =mContext.getSystemService(
"phone_msim");
simId_1 = 0;
simId_2 = 1;

Method mx = cx.getMethod("getDataState");
// int stateimei_1 = (Integer) mx.invoke(cx.newInstance());
int stateimei_2 = tm.getDataState();
Method mde = cx.getMethod("getDefault");
Method md = cx.getMethod("getDeviceId", int.class);
Method ms = cx.getMethod("getSubscriberId", int.class);
Method mp = cx.getMethod("getPhoneType");

// Object obj = mde.invoke(cx);

imei_1 = (String) md.invoke(obj, simId
4000
_1);
imei_2 = (String) md.invoke(obj, simId_2);

imsi_1 = (String) ms.invoke(obj, simId_1);
imsi_2 = (String) ms.invoke(obj, simId_2);

int statephoneType_1 = tm.getDataState();
int statephoneType_2 = (Integer) mx.invoke(obj);
Log.e("tag", statephoneType_1 +"---"+ statephoneType_2);

// Class<?> msc = Class.forName("android.telephony.MSimSmsManager");
// for (Method m : msc.getMethods()) {
// if (m.getName().equals("sendTextMessage")) {
// m.getParameterTypes();
// }
// Log.e("tag", m.getName());
// }

} catch (Exception e) {
isQualcommDoubleSim = false;
return;
}
isQualcommDoubleSim = true;

}

 

getPhoneType&getDataState 方法看了底层发现没有双卡实现，目前也不知道该咋办...
