I have to make an application which shows the Contact no of the SIM card that is being used in the cell. For that I need to use TelephonyManager class. Can i get details on its usage?
You can use the
TelephonyManager to do this:
TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); String number = tm.getLine1Number();
The documentation for
getLine1Number() says this method will return
null if the number is "unavailable", but it does not say when the number might be unavailable.
You'll need to give your application permission to make this query by adding the following to your Manifest:
(You shouldn't use
TelephonyManager.getDefault() to get the
TelephonyManager as that is a private undocumented API call and may change in future.)
