Android obtains carrier information (full version)-solves dual-card problems such as Qualcomm and MTK

Due to carrier problems in China, the problem of getting IMSI numbers from dual-card mobile phones should be implemented according to the manufacturer's API.

Next we will do a complete set of analysis operators to obtain the IMSI logic.

1. First, we need to determine the mobile phone platform.

1.1. Determine whether the mobile phone is MTK Platform

public static MtkDoubleInfo initMtkDoubleSim(Context mContext) {MtkDoubleInfo mtkDoubleInfo = new MtkDoubleInfo();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);mtkDoubleInfo.setSimId_1((Integer) fields1.get(null));Field fields2 = c.getField("GEMINI_SIM_2");fields2.setAccessible(true);mtkDoubleInfo.setSimId_2((Integer) fields2.get(null));Method m = TelephonyManager.class.getDeclaredMethod("getSubscriberIdGemini", int.class);mtkDoubleInfo.setImsi_1((String) m.invoke(tm,mtkDoubleInfo.getSimId_1()));mtkDoubleInfo.setImsi_2((String) m.invoke(tm,mtkDoubleInfo.getSimId_2()));Method m1 = TelephonyManager.class.getDeclaredMethod("getDeviceIdGemini", int.class);mtkDoubleInfo.setImei_1((String) m1.invoke(tm,mtkDoubleInfo.getSimId_1()));mtkDoubleInfo.setImei_2((String) m1.invoke(tm,mtkDoubleInfo.getSimId_2()));Method mx = TelephonyManager.class.getDeclaredMethod("getPhoneTypeGemini", int.class);mtkDoubleInfo.setPhoneType_1((Integer) mx.invoke(tm,mtkDoubleInfo.getSimId_1()));mtkDoubleInfo.setPhoneType_2((Integer) mx.invoke(tm,mtkDoubleInfo.getSimId_2()));if (TextUtils.isEmpty(mtkDoubleInfo.getImsi_1())&& (!TextUtils.isEmpty(mtkDoubleInfo.getImsi_2()))) {mtkDoubleInfo.setDefaultImsi(mtkDoubleInfo.getImsi_2());}if (TextUtils.isEmpty(mtkDoubleInfo.getImsi_2())&& (!TextUtils.isEmpty(mtkDoubleInfo.getImsi_1()))) {mtkDoubleInfo.setDefaultImsi(mtkDoubleInfo.getImsi_1());}} catch (Exception e) {mtkDoubleInfo.setMtkDoubleSim(false);return mtkDoubleInfo;}mtkDoubleInfo.setMtkDoubleSim(true);return mtkDoubleInfo;}

Identify exceptions directly. If an exception occurs, the MTK platform is not used.

1.2 determine whether the mobile phone is a Qualcomm Platform

public static GaotongDoubleInfo initQualcommDoubleSim(Context mContext) {GaotongDoubleInfo gaotongDoubleInfo = new GaotongDoubleInfo();gaotongDoubleInfo.setSimId_1(0);gaotongDoubleInfo.setSimId_2(1);try {Class
  cx = Class.forName("android.telephony.MSimTelephonyManager");Object obj = mContext.getSystemService("phone_msim");Method md = cx.getMethod("getDeviceId", int.class);Method ms = cx.getMethod("getSubscriberId", int.class);gaotongDoubleInfo.setImei_1((String) md.invoke(obj,gaotongDoubleInfo.getSimId_1()));gaotongDoubleInfo.setImei_2((String) md.invoke(obj,gaotongDoubleInfo.getSimId_2()));gaotongDoubleInfo.setImsi_1((String) ms.invoke(obj,gaotongDoubleInfo.getSimId_1()));gaotongDoubleInfo.setImsi_2((String) ms.invoke(obj,gaotongDoubleInfo.getSimId_2()));} catch (Exception e) {e.printStackTrace();gaotongDoubleInfo.setGaotongDoubleSim(false);return gaotongDoubleInfo;}return gaotongDoubleInfo;}

If an exception occurs, it is not the Qualcomm dual-card platform.

Then we sorted out the logic.

/*** @ Param c * @ return returns Platform Data */public Object isDoubleSim (Context c) {GaotongDoubleInfo gaotongDoubleInfo = MultiSimUtility. initQualcommDoubleSim (c); MtkDoubleInfo mtkDoubleInfo = MultiSimUtility. initMtkDoubleSim (c); boolean isGaoTongCpu = gaotongDoubleInfo. isGaotongDoubleSim (); boolean isMtkCpu = mtkDoubleInfo. isMtkDoubleSim (); if (isGaoTongCpu) {// Qualcomm chip dual-card return gaotongDoubleInfo;} else if (isMtkCpu) {// MTK chip dual-card return mtkDoubleInfo ;} else {// normal single-card mobile phone return null ;}}

At this time, we basically got information about the mobile phone platform and each card. A single-card mobile phone will not post code for obtaining information.
