如何获得Android设备唯一ID？

Question

可能重复:
是否有唯一的Android设备ID？

我使用下面的代码来获取Android设备IMEI,我如何更改下面的代码来获取Android设备唯一ID.

String getDeviceID1(TelephonyManager phonyManager){
    String id = phonyManager.getDeviceId();
    if (id == null){
        id = "not available";
    }
    int phoneType = phonyManager.getPhoneType();
    switch(phoneType){
        case TelephonyManager.PHONE_TYPE_NONE:
            return "" + id;

        case TelephonyManager.PHONE_TYPE_GSM:
            return "" + id;

        case TelephonyManager.PHONE_TYPE_CDMA:
            return "" + id;

        /*
        *  for API Level 11 or above
        *  case TelephonyManager.PHONE_TYPE_SIP:
        *   return "SIP";
        */

        default:
            return "" + id;
    }

    //I used to show IMEI 

    TextView textDeviceID = (TextView)findViewById(R.id.deviceid);
    //retrieve a reference to an instance of TelephonyManager
    TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    textDeviceID.setText(getDeviceID1(telephonyManager));
}

在Android中,您可以获得三种不同的唯一ID.

• IMEI(你的代码中已有)

  TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
  String id =  (getDeviceID1(telephonyManager));
  

• 设备编号

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

• 蓝牙地址(这对每个设备也是唯一的)

  private BluetoothAdapter mBtAdapter;
  
  // Get the local Bluetooth adapter
  mBtAdapter = BluetoothAdapter.getDefaultAdapter();
  String deviceMacAddress = mBtAdapter.getAddress();
