I am getting IMEI null in Android Q?

Android Q has restricted to access for both IMEI and serial no. It is available only for platform and apps with special carrier permission. Also the permission READ_PRIVILEGED_PHONE_STATE is not available for non platform apps.

If you try to access it throws below exception

java.lang.SecurityException: getImeiForSlot: The user 10180 does not meet the requirements to access device identifiers.

Please refer documentation: https://developer.android.com/preview/privacy/data-identifiers#device-ids

I am late to post answer. I still believe my answer will help someone. Android 10 Restricted developer to Access IMEI number.

You can have a alternate solution by get Software ID. You can use software id as a unique id. Please find below code as i use in Application.

public static String getDeviceId(Context context) {

 String deviceId;

    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        deviceId = Settings.Secure.getString(
                context.getContentResolver(),
                Settings.Secure.ANDROID_ID);
    } else {
        final TelephonyManager mTelephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (mTelephony.getDeviceId() != null) {
            deviceId = mTelephony.getDeviceId();
        } else {
            deviceId = Settings.Secure.getString(
                    context.getContentResolver(),
                    Settings.Secure.ANDROID_ID);
        }
    }

    return deviceId;
}

This just would not work as of Android Q. Third party apps can not use IMEI nor the serial number of a phone and other non-resettable device identifiers.

The only permissions that are able to use those is READ_PRIVILEGED_PHONE_STATE and that cannot be used by any third party apps - Manufacture and Software Applications. If you use that method you will get an error Security exception or get null .

You can still try to get a unique id by using:

import android.provider.Settings.Secure;

private String android_id = Secure.getString(getContext().getContentResolver(),Secure.ANDROID_ID);

As the best practices suggest. " you can avoid using hardware identifiers, such as SSAID (Android ID) and IMEI, without limiting required functionality."

Rather go for an instance ID such as String uniqueID = UUID.randomUUID().toString(); or FirebaseInstanceId.getInstance().getId();

The best way to get the IMEI number is as follows:

    public static String getIMEIDeviceId(Context context) {

        String deviceId;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q)
        {
            deviceId = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
        } else {
            final TelephonyManager mTelephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if (context.checkSelfPermission(Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
                    return "";
                }
            }
            assert mTelephony != null;
            if (mTelephony.getDeviceId() != null)
            {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
                {
                    deviceId = mTelephony.getImei();
                }else {
                    deviceId = mTelephony.getDeviceId();
                }
            } else {
                deviceId = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
            }
        }
        Log.d("deviceId", deviceId);
        return deviceId;
    }

Just copy the method and use it. It will definitely. However, you might know you can't get IMEI in android Q (version 10). In this code, you can get a unique identifier (alternative id) through any device or any API level. It works 100% Thank You!! And Enjoy Coding :)
