Access to standard android settings: PIN code of the SIM card

问题

This is my first question! I'd like to know how to access to standard settings in android, in particular SIM features. On boot, my Samsung i-9000 shows the window for insert the PIN code only for a few seconds, then disappears, so I'd like to develop by myself a widget for the homescreen that launch the standard window to insert the PIN code, but I don't know how can I do it!

Or someway to change the screen timeout of that window...

Thank you very much!

By using the TelephonyManager in Android.
You do not instantiate this class directly; instead, you retrieve a reference to an instance through Context.getSystemService(Context.TELEPHONY_SERVICE)

TelephonyManager manager = (TelephonyManager) Context.getSystemService(Context.TELEPHONY_SERVICE);
int state = manager.getSimState();
if(state == TelephonyManager.SIM_STATE_PIN_REQUIRED || state == TelephonyManager.SIM_STATE_PUK_REQUIRED)
{
         //PIN/PUK is required
}

May this will help you ...

If you would like to apply PIN in Android above 2.3 version, you have to install your app as a system app, in both cases you should use this code:

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
    Class c = Class.forName(tm.getClass().getName());
    Method m = c.getDeclaredMethod("getITelephony");
    m.setAccessible(true);
    ITelephony telephonyService;
    telephonyService = (ITelephony)m.invoke(tm);

    // Supply  SIM PIN
    SharedPreferences prefs = getSharedPreferences(OrangeSignalMeterLoop.class.getCanonicalName()+"x", Context.MODE_PRIVATE);
    if(prefs.getBoolean(context.getString(R.string.whetherAutoCompletePIN), false)) {
        String sim_pin = prefs.getString(context.getString(R.string.pinCode), "1111");  
        telephonyService.supplyPin(sim_pin);
    }

You probably will not be able use Internal class, the best tutorial how to use it you'll find here: https://devmaze.wordpress.com/2011/01/18/using-com-android-internal-part-1-introduction/
