How to get the mobile number of my device programmatically?

Huzaifa Asif :

I have tried using 2 methods for retrieving my phone number but both of them don't work. I used:

1. TelephonyManager
2. SubscriptionManager

I do get Network name, Country iso, and IMEI but whenever I try to return Number it returns nothing.

I have also added all the required permissions for these! My manifest looks like:

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

Code using TelephonyManager:

TelephonyManager phoneMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
phoneMgr.getLine1Number()

Code using SubscriptionManager:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        List<SubscriptionInfo> subscription = SubscriptionManager.from(getApplicationContext()).getActiveSubscriptionInfoList();
        for (int i = 0; i < subscription.size(); i++) {
            SubscriptionInfo info = subscription.get(i);
            Log.e("TAG", "number " + info.getNumber());
            Log.e("TAG", "network name : " + info.getCarrierName());
            Log.e("TAG", "country iso " + info.getCountryIso());
        }
    }

In both attempts I get nothing!

Is there any other way to get phone number or I'm doing something wrong?

Nowadays the TelephonyManager does not help us. Play Services API without permission is good solution for this.

This dependency is useful for this

 implementation 'com.google.android.gms:play-services-auth:16.0.1'

Now inside your Activity.java:

GoogleApiClient  mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(Auth.CREDENTIALS_API)
                .build();

        if (mGoogleApiClient != null) {
            mGoogleApiClient.connect();
        }

After this do request for Phone Number:

 HintRequest hintRequest = new HintRequest.Builder()
                .setPhoneNumberIdentifierSupported(true)
                .build();

        PendingIntent intent = Auth.CredentialsApi.getHintPickerIntent(mGoogleApiClient, hintRequest);
        try {
            startIntentSenderForResult(intent.getIntentSender(), 1008, null, 0, 0, 0, null);
        } catch (IntentSender.SendIntentException e) {
            Log.e("", "Could not start hint picker Intent", e);
        }

Now you need to handle response in your onActivityResult like this:

    @Override
    public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {
            case 1008:
                if (resultCode == RESULT_OK) {
                    Credential cred = data.getParcelableExtra(Credential.EXTRA_KEY);
//                    cred.getId====: ====+919*******
                    Log.e("cred.getId", cred.getId());
                    userMob = cred.getId();


                } else {
                    // Sim Card not found!
                    Log.e("cred.getId", "1008 else");

                    return;
                }


                break;
        }
    }
