如何在android中获取第二个sim的信息

Question

通过使用以下方法,我获得了sim one的信息

 TelephonyManager telephonyManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
            // Get the SIM country ISO code
            String simCountry = telephonyManager.getSimCountryIso();
            Log.e("Show:", simCountry);
            // Get the operator code of the active SIM (MCC + MNC)
            String simOperatorCode = telephonyManager.getSimOperator();
            Log.e("Show:", simOperatorCode);
            // Get the name of the SIM operator
            String simOperatorName = telephonyManager.getSimOperatorName();
            Log.e("Show:", simOperatorName);
            // Get the SIM’s serial number
            String simSerial = telephonyManager.getSimSerialNumber();
            Log.e("Show:", simSerial);
            // Get the phone number
            String mPhoneNumber = telephonyManager.getLine1Number();
            Log.e("Show:", mPhoneNumber);

如何获取双卡手机的第二个SIM卡的信息？

            // Get the phone number
            String mPhoneNumber = telephonyManager.getLine1Number();
            Log.e("Show:", mPhoneNumber);

在某些设备上工作

允许:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

所以我该怎么做？有错误吗？

从Android API 22开始，SubscriptionMananger可用你只需要调用
