Android Question Get the phone number and serial number of the device

[vecino]

Hi, so that's it, with "new" Android versions you can't get it anymore?
Thank you very much.

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

Everything important is listed there

Most of the device unique ids are not exposed. Two are available:
Advertising id: https://www.b4x.com/android/forum/threads/101050/#content
Phone.GetSettings ("android_id") - https://www.b4x.com/android/forum/threads/get-unique-id-for-user.124396/#content

 

[vecino]

The id that is most similar to mac address, phone number, IMEI and other no longer accessible ids, is the advertising identifier. This is a global id.

So, for example, from "settings", how is the IMEI displayed?

 

[vecino]

It seems that in the google play store there are applications to read the phone number, the IMEI, the serial number, etc..
There must be some way to read it.

You can get it with PhoneId from the Phone library, after you request the android.permission.READ_PHONE_STATE permission at runtime.

Once you see that it works, you need to:
1. Remove this permission with RemovePermission.
2. Add it with maxSdkVersion. Example here: https://www.b4x.com/android/forum/threads/runtime-permissions-android-6-0-permissions.67689/#content
3. Add the READ_PHONE_NUMBERS permission.

Request the correct permission based on Phone.SdkVersion.

I'm not sure I understand the steps given, I only get errors like the one that says READ_PHONE_NUMBERS permission does not exist.

Post the relevant code and the error message from the logs.

wow!

that's exactly what i was looking for very long time
i was told it is impossible
glad to see it is possible - will it pass google store ?
not sure i got the idea of the permissions change - will it be possible to load a short sample?

thanks

That's my problem, I don't understand how to follow the steps.

 

[Zeev Goldstein]

Anyone can help here please?
A short basic sample will be highly appreciated
Thanks

I have tried several times but have not been able to get anything because I do not understand the steps to follow.
I don't know how to remove a permission that is in the manifest, or add it, from runtime code.

Permission: READ_PHONE_NUMBERS

My app reads device's phone number, if any, so that user doesn't have to type it manually, which I also hope would deter abuse. All I need is just the phone number, no more, no less. My app doesn't make or manage phone calls. I make it clear by specifying "READ_PHONE_NUMBERS" permission in...

I have already tried this program, but in my case it does nothing, it does not show any message of any kind.

that's exactly why i asked for a simple example
we may have an error or something in what we try

Let's see if someone with more experience can help us.

no one?

It seems that no one is interested

In #7 you got told

Post the relevant code and the error message from the logs.

There is no such answer from you. What do you expect?

Hi, DonManfred, the problem is that I don't have any code because I don't understand the steps to follow with the permissions issue.
I just don't know where to start.
