public class Login extends AppCompatActivity {

    private Button loginBtn;
    private TextView textView;
    private String IMEINumber;




    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        loginBtn = (Button) findViewById(R.id.loginBtn);
        textView = (TextView) findViewById(R.id.textView);
        final int reqcode = 1;


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
        {
            String[] per = {Manifest.permission.READ_PHONE_STATE};

                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                            IMEINumber = tm.getImei();
                            textView.setText(IMEINumber);
                        }
                    } else {
                        IMEINumber = tm.getDeviceId();
