检测多 SIM 设备中来电的目标 SimCard

我读过很多帖子并尝试过很多解决方案，但所有帖子的共同点是它们都已经过时了，至少我找不到适用于较新版本的 Android 的解决方案。

Post 1 https://stackoverflow.com/a/21454296/6444297， 结果：intent.getExtras().getInt("simId", -1)总是返回-1

Post 2 https://stackoverflow.com/a/35555668/6444297， 结果：intent.getExtras().getInt("slot", -1)总是返回-1

Post 3 https://stackoverflow.com/a/54166869/6444297， 结果：

String[] array = new String[]{
        "extra_asus_dial_use_dualsim",
        "com.android.phone.extra.slot",
        "slot",
        "simslot",
        "sim_slot",
        "subscription",
        "Subscription",
        "phone",
        "com.android.phone.DialingMode",
        "simSlot",
        "slot_id",
        "simId",
        "simnum",
        "phone_type",
        "slotId",
        "slotIdx"
};

for (String item :
        array) {
    Log.i(TAG, "Sim Card - " + item + " -----> " + intent.getExtras().getInt(item));
}

Logs:

PhoneCallReceiver: Sim Card - extra_asus_dial_use_dualsim -----> 0
PhoneCallReceiver: Sim Card - com.android.phone.extra.slot -----> 0
PhoneCallReceiver: Sim Card - slot -----> 0
PhoneCallReceiver: Sim Card - simslot -----> 0
PhoneCallReceiver: Sim Card - sim_slot -----> 0
PhoneCallReceiver: Sim Card - subscription -----> 0
PhoneCallReceiver: Sim Card - Subscription -----> 0
PhoneCallReceiver: Sim Card - phone -----> 0
PhoneCallReceiver: Sim Card - com.android.phone.DialingMode -----> 0
PhoneCallReceiver: Sim Card - simSlot -----> 0
PhoneCallReceiver: Sim Card - slot_id -----> 0
PhoneCallReceiver: Sim Card - simId -----> 0
PhoneCallReceiver: Sim Card - simnum -----> 0
PhoneCallReceiver: Sim Card - phone_type -----> 0
PhoneCallReceiver: Sim Card - slotId -----> 0
PhoneCallReceiver: Sim Card - slotIdx -----> 0

对于第一个 SimCard 和第二个 SimCard，它显示具有相同值 0 的相同日志。

我也尝试过其他类似的帖子。没有一个适用于新版本的Android！

是否有其他适用于较新版本的 Android（7.0 或更高版本）的解决方案？

正式，唯一记录的值 https://developer.android.com/reference/android/telephony/TelephonyManager.html#EXTRA_INCOMING_NUMBER意图提供的是电话号码。

一些构造函数在意图中添加其他值，例如 sim 插槽号，但这不是强制性的。这就是为什么有这么多可能的槽键名称，就像post 3 https://stackoverflow.com/questions/48868040/how-can-i-detect-the-new-outgoing-call-from-which-sim-in-dual-sim-devices/54166869#54166869，每个构造函数添加自己的实现。

某些构造函数也可能没有在某些模型中添加此值，您的模型肯定就是这种情况。如果构造函数不提供该值，则无法找到该值。
