如何找出EMULATOR的電話號碼

Nothing is easier to be done, if you know where to search for it
The SystemProperties provide a bunch of data of the current Phone-'Properties', like:

• the operator-Name (i.e.: "T-Mobile" or "AT&T"
  
• the ISO-Country-Name (i.e.: "us" or "de")
  
• and of course your Phone-Number

This is how to get these Strings into your Java-Code:

Java:

String phoneNumber = android.os.SystemProperties.get( android.telephony.TelephonyProperties.PROPERTY_LINE1_NUMBER); String operatorISOCountry = android.os.SystemProperties.get( android.telephony.TelephonyProperties.PROPERTY_OPERATOR_ISO_COUNTRY); String operatorName =android.os.SystemProperties.get( android.telephony.TelephonyProperties.PROPERTY_OPERATOR_ALPHA);;

On the emulator this will return: "15555218135", "us" and "Android".
