Android Question Phone Number of Device

Intelemarketing · Oct 2, 2020

I have a need to access the phone number of the Phone running my app.
I have found so many, many references to Phone on the forum, but none that tell me what the phone number of the phone is

Any ideas please

B4X:

Dim pi As PhoneId
Log(pi.GetLine1Number)

But you need to check for permission

B4X:

dim rp As RuntimePermissions
rp.PERMISSION_READ_PHONE_STATE

In most case You can't, because it is operator side function.

The Example Worked but displayed BLANK as the phone number

Also Warning:
The recommended value for android:targetSdkVersion is 29 or above (manifest editor). (warning #31)

No worries - Thanks for you help

PhoneId in huawei Y9 android 9

does not show the phone number in dual SIM

Hi oparra - Not happy on my phone - Since the results appear to be random and inconsistent, it appears that the easiest solution is to get the User to key in their phone number. This is akin to what happens when a website asks you to key in your email address to validate that you are who you say you are. This will be fine for what I have in mind.

yes.

if better ask for the phone number.

For security policies, it is with the consent of the user.

In most applications, they ask the user to enter the phone number.
