ANDROID_ID

ANDROID_ID

import android.provider.Settings.Secure;

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

The above is from the link @ Is there a unique Android device ID?

以上是来自链接@是否有唯一的Android设备ID?

More specifically, Settings.Secure.ANDROID_ID. This is a 64-bit quantity that is generated and stored when the device first boots. It is reset when the device is wiped.

更具体地说,Settings.Secure.ANDROID_ID。这是一个64位的量，在设备第一次启动时生成并存储。当设备被擦除时重置。

ANDROID_ID seems a good choice for a unique device identifier. There are downsides: First, it is not 100% reliable on releases of Android prior to 2.2 (“Froyo”). Also, there has been at least one widely-observed bug in a popular handset from a major manufacturer, where every instance has the same ANDROID_ID.

android id似乎是唯一设备标识符的好选择。缺点是:首先，在2.2(“Froyo”)之前，Android的发布不是100%可靠的。此外，在一家主要制造商的流行手机中，至少有一个广泛观察到的bug，每个实例都具有相同的ANDROID_ID。

The below solution is not a good one coz the value survives device wipes (“Factory resets”) and thus you could end up making a nasty mistake when one of your customers wipes their device and passes it on to another person.

下面的解决方案不是一个好的解决方案，因为该值在设备擦除(“工厂重置”)之后仍然存在，因此当您的一个客户擦去他们的设备并将其传递给另一个人时，您最终可能会犯严重的错误。

You get the imei number of the device using the below

你可以使用下面的方法得到设备的imei号码。

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

http://developer.android.com/reference/android/telephony/TelephonyManager.html getDeviceId % 29 28%

Add this is manifest

添加这是清单

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

Conclusion For the vast majority of applications, the requirement is to identify a particular installation, not a physical device. Fortunately, doing so is straightforward.

结论对于绝大多数应用来说，需求是确定一个特定的安装，而不是物理设备。幸运的是，这样做很简单。

There are many good reasons for avoiding the attempt to identify a particular device. For those who want to try, the best approach is probably the use of ANDROID_ID on anything reasonably modern, with some fallback heuristics for legacy devices

避免试图识别特定设备的原因有很多。对于那些想要尝试的人来说，最好的方法可能是使用ANDROID_ID在任何合理的现代版本上，并使用一些用于遗留设备的后继启发式方法。
