There are 4 ways of getting HWID:

1. ApplicationID

2. Serial number (obsolete)

3. IMEI (obsolete)

4. MAC address (obsolete)

5. AndroidID

Android versions dependency

Android 8 and above:      Neither Android serial number nor IMEI is accessible since Android 8.X OS.

Android 10 and above:    MAC based licensing is working, but limited, due to MAC randomization (more details below).

Android 13 and above:    MAC based licensing is not working anymore. Only working types are: ApplicationID and AndroidID.

• ApplicationID-based licenses:
  • Binded to Android applicationID parameter of APK. (each different APK needs unique license)
  • Unlimited to number of devices (one license file for N devices)
• MAC-based licenses:
  • Binded to specific MAC address of device's network interface. (each device needs unique license )
  • Unlimited to number of APKs (one license file of device can be used for N different applications)
  • Note: From Android 10 the MAC-based licensing works only for target SDK versions less than 30
  • Warning: MAC-based licensing is not supported since Android 13
• AndroidID licenses:
  • Binded to specific Android device (each device needs unique license)
  • Unlimited to number of APKs (one license file of device can be used for N different applications)

1. ApplicationID based HWID

Returned by IEngine_GetHardwareId function in all Innovatrics' SDKs or by License manager desktop utility using command license_manager -c --appid "<your_aplicationID>".

    Example to get Application based HWID:

String hwid = new String(AnsiIso.getHardwareId());
showMessage("This device's HWID is: " + hwid);

2. Serial number based HWID

Returned by IEngine_GetHardwareId function in old versions of Innovatrics' SDKs (e.g. IDKit SDK v5.3.1, IFace SDK v3.2.2, ANSI&ISO SDK v2.1.0, Segmentation SDK v1.8.0 or older).

3. IMEI based HWID

Returned by IEngine_GetHardwareId function if no serial number is found. You can also find the IMEI of your device in Settings->About phone->Status or by entering a special code *#06# using the device's keypad according to http://www.phonearena.com/news/How-to-find-a-phones-IMEI-number_id62867. Please note that you have to add letter 'M' before the IMEI number and then add it to CRM license generator. For example if the IMEI=123456789012345 then the Hardware ID=M123456789012345. You also have to add following permission to application's manifest file in order to use IMEI as Hardware ID:

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

In case you have decided to use MAC-based license, you also need to make sure the following permissions are in your project's manifest:    

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Since Android 10 you need to disable MAC address randomization to get a static hardware id.

It is only possible to disable MAC address randomization per Wi-Fi connection, so if you connect to another Wi-Fi network, the randomization will be turned on.

    Example to get MAC based HWID:

String macHwid = new String(AnsiIso.getHardwareId(AnsiIso.AnsiIsoHwidMethod.MAC_ADDR));
showMessage("This device's MAC HWID is: " + macHwid);

5. AndroidID based HWID

Implemented in the newest SDKs versions. Returned by getHardwareId function.

    Example

String hwida = new String(AnsiIso.getHardwareId(AnsiIso.AnsiIsoHwidMethod.ANDROID_ID));
showMessage("This device's Android ID HWID is: " + hwida);
