How to Change Android Device Unique ID - Simplest Method, 100% works

Hello Guys here I am going to tell you that how you can change your Android Device Unique ID...!!!

But before that you need to know that :

WHAT IS ANDROID  UNIQUE ID ?
Each Android devices allow to read the device settings via the
class “Secure”. Especially for C2DM you have a need to uniquely identify the Android device so that you do not register the device several times for Cloud-to-device-messaging. From the Javadoc of “android.provider.Settings.Secure.ANDROID_ID”:

A 64-bit number (as a hex string) that is randomly generated on the device’s first boot and should remain constant for the lifetime of the device. (The value may change if a factory reset is performed on the device.)

Android ID which we retrieve using  Secure.getString(getContentResolver(), Secure.ANDROID_ID);

Here is a little Activity which read this device identifier and shows it as a Toast.


1 package de.vogella.android.deviceinfo;
2
3 import android.app.Activity;
4 import android.os.Bundle;
5 import android.provider.Settings.Secure;
6 import android.widget.Toast;
7
8 public class ShowDeviceInfo extends Activity {
9      /** Called when the activity is first created. */
10@Override
11 public void onCreate(Bundle savedInstanceState) {
12         super.onCreate(savedInstanceState);
13       setContentView(R.layout.main);
14      String deviceId = Secure.getString(this.getContentResolver(),
15               Secure.ANDROID_ID);
16       Toast.makeText(this, deviceId, Toast.LENGTH_SHORT).show();
17   }
18}

This way you can make sure that certain thing a uniquely defined for your device.

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.

But Guy's leave all these knowledgy stuff :)
