Below different methods of session login in android.

Session login in Activity:

public class LoginUsingActivityActivity extends Activity {
private static final String URL_PREFIX_FRIENDS = "https://graph.facebook.com/me/friends?access_token=";
private Button buttonLoginLogout;
private Session.StatusCallback statusCallback = new SessionStatusCallback();

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
buttonLoginLogout = (Button)findViewById(R.id.buttonLoginLogout);

Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

Session session = Session.getActiveSession();
if (session == null) {
if (savedInstanceState != null) {
session = Session.restoreSession(this, null, statusCallback, savedInstanceState);
}
if (session == null) {
session = new Session(this);
}
Session.setActiveSession(session);
if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
}
}

updateView();
}

@Override
public void onStart() {
super.onStart();
Session.getActiveSession().addCallback(statusCallback);
}

@Override
public void onStop() {
super.onStop();
Session.getActiveSession().removeCallback(statusCallback);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
Session session = Session.getActiveSession();
Session.saveSession(session, outState);
}

private void updateView() {
Session session = Session.getActiveSession();
if (session.isOpened()) {
buttonLoginLogout.setText(R.string.logout);
buttonLoginLogout.setOnClickListener(new OnClickListener() {
public void onClick(View view) { onClickLogout(); }
});
} else {

buttonLoginLogout.setText(R.string.login);
buttonLoginLogout.setOnClickListener(new OnClickListener() {
public void onClick(View view) { onClickLogin(); }
});
}
}

private void onClickLogin() {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
} else {
Session.openActiveSession(this, true, statusCallback);
}
}

private void onClickLogout() {
Session session = Session.getActiveSession();
if (!session.isClosed()) {
session.closeAndClearTokenInformation();
}
}

private class SessionStatusCallback implements Session.StatusCallback {
@Override
public void call(Session session, SessionState state, Exception exception) {
updateView();
}
}
}

If you are using fragment in your project use below code for Fragment to use Session login.

Session login in Fragment:

public class SessionLoginFragment extends Fragment {
private static final String URL_PREFIX_FRIENDS = "https://graph.facebook.com/me/friends?access_token=";
private Button buttonLoginLogout;
private Session.StatusCallback statusCallback = new SessionStatusCallback();

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment, container, false);

buttonLoginLogout = (Button) view.findViewById(R.id.buttonLoginLogout);

Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

Session session = Session.getActiveSession();
if (session == null) {
if (savedInstanceState != null) {
session = Session.restoreSession(getActivity(), null, statusCallback, savedInstanceState);
}
if (session == null) {
session = new Session(getActivity());
}
Session.setActiveSession(session);
if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
}
}

updateView();

return view;
}

@Override
public void onStart() {
super.onStart();
Session.getActiveSession().addCallback(statusCallback);
}

@Override
public void onStop() {
super.onStop();
Session.getActiveSession().removeCallback(statusCallback);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(getActivity(), requestCode, resultCode, data);
}

@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
Session session = Session.getActiveSession();
Session.saveSession(session, outState);
}

private void updateView() {
Session session = Session.getActiveSession();
if (session.isOpened()) {
buttonLoginLogout.setText(R.string.logout);
buttonLoginLogout.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) { onClickLogout(); }
});
} else {
buttonLoginLogout.setText(R.string.login);
buttonLoginLogout.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) { onClickLogin(); }
});
}
}

private void onClickLogin() {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
} else {
Session.openActiveSession(getActivity(), this, true, statusCallback);
}
}

private void onClickLogout() {
Session session = Session.getActiveSession();
if (!session.isClosed()) {
session.closeAndClearTokenInformation();
}
}

private class SessionStatusCallback implements Session.StatusCallback {
@Override
public void call(Session session, SessionState state, Exception exception) {
updateView();
}
}
}
