telephonymanager

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) Is there any

I want to know whether I am in a call. If I am in a call then start the service (service part is clear). How do I do this? While attending the call I need to call the service... I am unaware of how to do this? Any help? You need broadcast receiver ... In manifest declare broadcast receiver ... <receiver android:name=".PhoneStateBroadcastReceiver"> <intent-filter> <action android:name="android.intent.action.PHONE_STATE"/> </intent-filter> </receiver> Also declare uses-permission ... <uses-permission android:name="android.permission.READ_PHONE_STATE" /> The broadcast receiver class ... package x
