importandroid.provider.Settings.Secure;

privateString android_id = Secure.getString(getBaseContext().getContentResolver(), Secure.ANDROID_ID);

或者

import Android.Provider.Settings.System;  

String Android_ID = System.getString(this.getContentResolver(), System.ANDROID_ID);  

或者

1.获取手机设备的唯一码(IMIE )
public void fetch_status(){ 
    TelephonyManager tm = (TelephonyManager) this 
    .getSystemService(Context.TELEPHONY_SERVICE);//     
    String str = ""; 
    str += "DeviceId(IMEI) = " + tm.getDeviceId() + "\n";   
    str += "DeviceSoftwareVersion = " + tm.getDeviceSoftwareVersion() + "\n";   
    str += "Line1Number = " + tm.getLine1Number() + "\n";   
    str += "NetworkCountryIso = " + tm.getNetworkCountryIso() + "\n";   
    str += "NetworkOperator = " + tm.getNetworkOperator() + "\n";   
    str += "NetworkOperatorName = " + tm.getNetworkOperatorName() + "\n";   
    str += "NetworkType = " + tm.getNetworkType() + "\n";   
    str += "PhoneType = " + tm.getPhoneType() + "\n";   
    str += "SimCountryIso = " + tm.getSimCountryIso() + "\n";   
    str += "SimOperator = " + tm.getSimOperator() + "\n";   
    str += "SimOperatorName = " + tm.getSimOperatorName() + "\n";   
    str += "SimSerialNumber = " + tm.getSimSerialNumber() + "\n";   
    str += "SimState = " + tm.getSimState() + "\n";   
    str += "SubscriberId(IMSI) = " + tm.getSubscriberId() + "\n";   
    str += "VoiceMailNumber = " + tm.getVoiceMailNumber() + "\n";   
    TextView sys = (TextView) findViewById(R.id.sys); 
    sys.setText(str); 
} 

2.在AndroidManifest.xml里添加权限

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