How do I get an unique ID from an Android phone?

如何从 Android 手机获取唯一 ID？

Whenever I try to get the unique ID from the phone as a string it always shows android idand no other unique hex values.

每当我尝试从手机中获取唯一 ID 作为字符串时，它总是显示android id而没有其他唯一的十六进制值。

How do I get that one?

我怎么得到那个？

This is the code I use to get the ID until now:

这是迄今为止我用来获取 ID 的代码：

String id=Settings.Secure.getString(contentResolver,Settings.Secure.ANDROID_ID);
Log.i("Android is is:",id);

the output which I get looks like this:

我得到的输出如下所示：

Android id is: android id

I am using a Nexus One for testing.

For detailed instructions on how to get a Unique Identifier for each Android device your application is installed from, see this official Android Developers Blog posting:

有关如何为安装应用程序的每个 Android 设备获取唯一标识符的详细说明，请参阅此官方 Android 开发人员博客帖子：

It seems the best way is for you to generate one your self upon installation and subsequently read it when the application is re-launched.

似乎最好的方法是在安装时自己生成一个，然后在重新启动应用程序时阅读它。

I personally find this acceptable but not ideal. No one identifier provided by Android works in all instances as most are dependent on the phone's radio states (wifi on/off, cellular on/off, bluetooth on/off). The others like Settings.Secure.ANDROID_ID must be implemented by the manufacturer and are not guaranteed to be unique.

我个人认为这可以接受但并不理想。Android 提供的任何标识符都不能在所有情况下都有效，因为大多数标识符取决于手机的无线电状态（wifi 开/关、蜂窝网络开/关、蓝牙开/关）。其他如 Settings.Secure.ANDROID_ID 必须由制造商实施，并且不保证是唯一的。

The following is an example of writing data to an INSTALLATION file that would be stored along with any other data the application saves locally.

以下是将数据写入 INSTALLATION 文件的示例，该文件将与应用程序在本地保存的任何其他数据一起存储。

public class Installation {
    private static String sID = null;
    private static final String INSTALLATION = "INSTALLATION";

    public synchronized static String id(Context context) {
        if (sID == null) {  
            File installation = new File(context.getFilesDir(), INSTALLATION);
            try {
                if (!installation.exists())
                    writeInstallationFile(installation);
                sID = readInstallationFile(installation);
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
        return sID;
    }

    private static String readInstallationFile(File installation) throws IOException {
        RandomAccessFile f = new RandomAccessFile(installation, "r");
        byte[] bytes = new byte[(int) f.length()];
        f.readFully(bytes);
        f.close();
        return new String(bytes);
    }

    private static void writeInstallationFile(File installation) throws IOException {
        FileOutputStream out = new FileOutputStream(installation);
        String id = UUID.randomUUID().toString();
        out.write(id.getBytes());
        out.close();
    }
}

((TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId();

with manifest

有清单

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

Try setting it to something other than 'android id' and see if you read the new value.

尝试将其设置为“android id”以外的其他内容，看看您是否读取了新值。

Here is code segment how to get androidId, unique DeviceId and Serial Number for your android phone may be it helps you.

以下是如何为您的 android 手机获取 androidId、唯一 DeviceId 和序列号的代码段可能对您有所帮助。

TelephonyManager tm = (TelephonyManager)getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);
           final String DeviceId, SerialNum, androidId;
            DeviceId = tm.getDeviceId();
            SerialNum = tm.getSimSerialNumber();
            androidId = Secure.getString(getContentResolver(),Secure.ANDROID_ID);

            UUID deviceUuid = new UUID(androidId.hashCode(), ((long)DeviceId.hashCode() << 32) | SerialNum.hashCode());
            String mydeviceId = deviceUuid.toString();
            Log.v("My Id", "Android DeviceId is: " +DeviceId); 
            Log.v("My Id", "Android SerialNum is: " +SerialNum); 
            Log.v("My Id", "Android androidId is: " +androidId);

Wireless MAC address is more unique than IMEI, because the later gets spoofed on stolen devices. Drawback is that it only works on WiFi enabled devices. WifiInfo

无线 MAC 地址比 IMEI 更独特，因为后者会在被盗设备上被欺骗。缺点是它只适用于支持 WiFi 的设备。无线上网信息

Settings.Secure.getString(contentResolver,Settings.Secure.ANDROID_ID);

this is not a good method it will return null in some cases.

这不是一个好方法，它在某些情况下会返回 null。
