检测在双SIM卡Android手机的两个SIM卡的状态
我想检测两个SIM卡是否存在在我的双SIM卡的android手机编程。我发现一个API（ TelephonyManager.getSIMState（）），但它是正常的单卡手机。是否有任何的API，以检测是否不是两个SIM卡插在我的双SIM卡手机？
I want to detect whether two SIM cards are there in my dual-SIM android phone programmatically. I found one API (TelephonyManager.getSIMState()), but it is for normal single-SIM phones. Are there any APIs to detect whether or not two SIMs are inserted in my dual-SIM phone?
Android不支持多SIM卡，从SDK最少。谁创造多SIM设备设备制造商对自己这样做。欢迎您咨询您的设备制造商，看看他们是否有一个SDK插件或东西，可以让你进入第二个SIM卡。
Android does not support multiple SIMs, at least from the SDK. Device manufacturers who have created multi-SIM devices are doing so on their own. You are welcome to contact your device manufacturer and see if they have an SDK add-on or something that allows you to access the second SIM.

自22 API，您可以检查使用多个SIM卡 SubscriptionManager 的方法 getActiveSubscriptionInfoList（）。在Android文档。
Since API 22, you can check for multiple SIMs using SubscriptionManager's method getActiveSubscriptionInfoList(). More details on Android Docs.
