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_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...
未完待续....
