android 获取手机设备的唯一码(IMIE ) 注册用

 private void getAndroidId(){
 String androidId = System.getString(getContentResolver(), System.ANDROID_ID);
 Log.e("ANDROID_ID", androidId + " ");
 }

AndroidManifest.xml必须以下设置
<!-- 读取手机信息 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

import Android.Provider.Settings.System;  

android.provider.Settings.System.ANDROID_ID

tm.getDeviceId()表示唯一的设备ID，例如对于GSM 手机返回IMEI，对于CDMA 手机返回MEID,如果设备不可用则返回NULL，比如在模拟器上。

System.getString(getContentResolver(), System.ANDROID_ID)表示一个64位的数字，在设备第一次启动的时候随机生成并在设备的整个生命周期中不变。（如果重新进行出厂设置可能会改变）
