如何监控SIM卡状态变化 [英] How to monitor SIM state change

问题描述

我希望能够做一些东西，当SIM卡状态变化，即播放声音时，SIM卡的PIN是必需的，但我认为没有任何广播的事件，可以由广播接收这个被截获.. 。报名参加的 android.intent.action 的.PHONE_STATE也只能告诉你，当呼叫状态的变化..另一种可启动的注册表服务的 PhoneStateListener 的和在反应一个LISTEN_SERVICE_STATE（当状态是OUT-OF-STATE它可以得到的SIM卡状态下从的 TelephonyManager 的，看看如果状态SIM_STATE_PIN_REQUIRED）。所以，我的问题是：

I'd like to be able to do some stuff when the SIM state change, i.e. play a sound when SIM PIN is required, but I think there are no Broadcast events that can be intercepted by a broadcast receiver for this... registering for android.intent.action.PHONE_STATE does only tell you when the CALL-STATE changes.. An alternative can be starting a service that registers a PhoneStateListener and reacts upon a LISTEN_SERVICE_STATE (when the state is OUT-OF-STATE it can get the SIM state from the TelephonyManager and look if the state is SIM_STATE_PIN_REQUIRED). So, my questions are:

1）有没有广播的意图，我可以用它来拦截SIM卡状态改变或服务状态变化？

1) Is there any broadcast intent that I can use to intercept a SIM state change or a Service State change?

2）这是个坏主意，安装的 PhoneStateListener 的内部服务，并使用它的手机状态的通知后交付意图服务本身改变接收通过的 PhoneStateListener 的？

2) is it a bad idea to install a PhoneStateListener within a Service and use it to deliver intents to the Service itself upon the notification of a phone state changed received by the PhoneStateListener?

推荐答案

意图 android.intent.action.SIM_STATE_CHANGED 是广播，当SIM卡状态的变化。例如，在我的HTC Desire采用了T-Mobile的SIM卡，如果我把设备进入飞行模式下意图是广播：

The Intent android.intent.action.SIM_STATE_CHANGED is broadcast when the SIM state changes. For example, on my HTC Desire with a T-Mobile SIM card, if I put the device into flight mode the following Intent is broadcast:

• 意图：android.intent.action.SIM_STATE_CHANGED与演员：SS = NOT_READY，原因= NULL

如果我再取出来的飞行模式，下面的意图是广播：

If I then take it out of flight mode, the following Intents are broadcast:

• 意图：android.intent.action.SIM_STATE_CHANGED与演员：SS =锁定，原因= PIN
• 意图：android.intent.action.SIM_STATE_CHANGED与演员：SS = READY，原因= NULL
• 意图：android.intent.action.SIM_STATE_CHANGED与演员：SS = IMSI，原因= NULL
• 意图：android.intent.action.SIM_STATE_CHANGED与演员：SS =加载，原因= NULL

有可能的是不同的制造商和型号不同表现不同。正如他们所说，你的情况可能会有所不同。

It is possible that different manufacturers and different models behave differently. As they say, "Your mileage may vary".
