How can I get my own phone number programmatically in Android?

Question

I tried the following code to get my own number and get a NULL string. What is the problem?

TelephonyManager mTelephonyMgr;     
 mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);     
 String phoneNumber = mTelephonyMgr.getLine1Number();

Permission

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Use TelephonyManager.getLine1Number()

But you need to have stored the phone number on the SIM card, and there´s no other way to get your "own number".

Example:

TelephonyManager tm = (TelephonyManager)this.getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE); 
String myPhoneNumber =  tm.getLine1Number();

and you need this permission into your Manifest.xml

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

See this Question: TelephonyManager.getLine1Number() failing? as describe, you need to evaluate:

if("SIM card present" && "phone number is stored") {
  "get the phone number with TelephonyManager.getLine1Number"
}

Add this to your manifest

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

You need the user's permission to retrieve this data

If it still returns null, that means the data is not available, and you cant use it.
