How to find out from code if my Android app runs on emulator or real device?

I have read this stackoverflow thread already and I tried using the code given in that answer to find out if I run my code on the emulator or on a real device:

import android.content.ContentResolver;
import android.provider.Settings.Secure;
...     
mTextView.setText(Secure.getString(getContentResolver(), Secure.ANDROID_ID));

On my real device it returns "2bccce3...", however on the emulator it does not return null, but also a string "bd9f8..."

Ideas how to find out if emulator or real device from code would be highly appreciated

This is the standard google flutter emulator check :

public boolean isEmulator() {
    return (Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic"))
            || Build.FINGERPRINT.startsWith("generic")
            || Build.FINGERPRINT.startsWith("unknown")
            || Build.HARDWARE.contains("goldfish")
            || Build.HARDWARE.contains("ranchu")
            || Build.MODEL.contains("google_sdk")
            || Build.MODEL.contains("Emulator")
            || Build.MODEL.contains("Android SDK built for x86")
            || Build.MANUFACTURER.contains("Genymotion")
            || Build.PRODUCT.contains("sdk_google")
            || Build.PRODUCT.contains("google_sdk")
            || Build.PRODUCT.contains("sdk")
            || Build.PRODUCT.contains("sdk_x86")
            || Build.PRODUCT.contains("vbox86p")
            || Build.PRODUCT.contains("emulator")
            || Build.PRODUCT.contains("simulator");
}

As of writing this, nothing in this thread worked for the Bluestacks 4 emulator except trying to check for sensors. And so I checked the battery temperature using this gist. It should return 0.0 which means it does not have a battery temperature (and therefore it's an emulator).

public float getCpuTemp() {
    Process process;
    try {
        process = Runtime.getRuntime().exec("cat sys/class/thermal/thermal_zone0/temp");
        process.waitFor();
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = reader.readLine();
        float temp = Float.parseFloat(line) / 1000.0f;
        return temp;
    } catch (Exception e) {
        e.printStackTrace();
        return 0.0f;
    }
}
