Re: [android-developers] Re: TelephonyManager.getLine1Number() returns null always

Hi Raghav,

I am also using TelephonyManager.getLine1Number() method to get current mobile number.

But it is returning empty string always as in setting it displayed Unknown for My Phone Number.

I need current mobile number to initiate the call. I have to initiate a call to current number only. 

So please let me know if you have any work around regarding this.

Why do you need this? Are you trying to uniquely identify individual installs? If so, what will you do if your user doesn't have a SIM in his phone, or is  on a tablet? Search the list. Identifying installs uniquely has been discussed before.

FYI, to see if the carrier stores the number on your SIM, go to Settings -> About Phone -> Status -> My phone Number (In ICS. Other versions may vary slightly.) If it displays unknown there, then your number is not stored on the SIM.

Thanks

I had given read phone state permission for this. still i am getting
null not empty string.

In android we can get sim serial number. So, is there any third API to
get the mobile number which is associated with SIM serial number.
