How to obtain the IMEI code in Android

Core code:
Imei = (TelephonyManager) getSystemService (TELEPHONY_SERVICE ))
. GetDeviceId ();
1. Add Permissions
In the manifest. xml file, add <uses-permission android: name = "android. permission. READ_PHONE_STATE"/>
2. Code
Copy codeThe Code is as follows: package net. sunniwell. app;
Import android. app. Activity;
Import android. OS. Bundle;
Import android. telephony. CellLocation;
Import android. telephony. PhoneStateListener;
Import android. telephony. TelephonyManager;
Public class TelManager extends Activity {

@ Override
Protected void onCreate (Bundle savedInstanceState ){
Super. onCreate (savedInstanceState );
TelephonyManager tm = (TelephonyManager) this. getSystemService (TELEPHONY_SERVICE );
