查看android.provider.Secure.Settings中的常量ANDROID_ID。

http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID

Android手机上有三种类型的标识符。

IMEI

IMSI

String ts = Context.TELEPHONY_SERVICE; TelephonyManager mTelephonyMgr =（TelephonyManager）getSystemService（ts）; String imsi = mTelephonyMgr.getSubscriberId（）; String imei = mTelephonyMgr.getDeviceId（）;

Android ID它是在设备第一次启动时生成的64位十六进制字符串。 一般情况下，除非出厂重置，否则不会更改。

Secure.getString（getContentResolver（），Secure.ANDROID_ID）;

使用下面的行，

import android.provider.Settings.Secure;

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

试试这个代码：

 Will return the MDN or MEID of the device depending on which radio the
 phone uses (GSM or CDMA). Each device MUST return a unique value here
 (assuming it's a phone). This should work for any Android device with a
  sim slot or CDMA radio. Requires READ_PHONE_STATE permission

public static String getDeviceUID(Context context) {
    TelephonyManager tManager = (TelephonyManager) context
            .getSystemService(Context.TELEPHONY_SERVICE);
    return tManager.getDeviceId();
}


  The Android ID (a unique 64-bit value) as a hex string. Identical to that
  obtained by calling GoogleLoginService.getAndroidId(); it is also placed
  here so you can get it without binding to a service.

public static String getAndroidID(Context context) {
    return Settings.System.getString(context.getContentResolver(),
            Settings.Secure.ANDROID_ID);
}
