I have two activity, activity 1 and activity 2 . in activity 2 there is something which i want to use from activity 1 button click

       protected void onNext() {

    AuthType authType = getSelectedAuthType();

    if (authType == AuthType.XOAUTH2) {

        Globals.getOAuth2TokenProvider().authorizeAPI(mAccount.getEmail(), this,

                new OAuth2TokenProvider.OAuth2TokenProviderAuthCallback() {

            @Override

            public void success() {

                updateAccountSettings("");

                AccountSetupCheckSettings.actionCheckSettings(

                        AccountSetupIncoming.this, mAccount, CheckDirection.INCOMING);

            }



            @Override

            public void failure(AuthorizationException e) {

                AccountSetupIncoming.this.failure(e);

            }

        });

        return;

    }

    updateAccountSettings(mPasswordView.getText().toString());

    AccountSetupCheckSettings.actionCheckSettings(this, mAccount, CheckDirection.INCOMING);

}

This code is in activity 2 and i want to use this code from activity 1 button click.

I am working on a email application and above code will be use to login with google xoauth2 ,

Bellow is the code from activity 1 which will be use for gmail xoauth if user clicks it will go to activity 2 and use above code

  private void onNext() {

    if (mOAuth2CheckBox.isChecked()) {

        // Auto-setup doesn't support client certificates.

        activity2();

        return;

    }

1:
if you want to jump to the another activity and run the code you mentioned, you can pass a flag in your intent for the second activity.
for example

Intent intent = new Intent(FirstActivity.this,SecondActivity.class);

intent.putExtran("EXECUTE_CODE",true);

startActivity(intent);

further in the oncreate of second activity you can check if the flag is true.

bool executeCode = getIntent().getExtras().getBoolean("EXECUTE_CODE");

   if(executeCode){

         RunCodeYouWantToExecute()

        }

2: if you want to get the result back in the firstActivity you can use

Intent intent = new Intent(FirstActivity.this,SecondActivity.class);

    intent.putExtran("EXECUTE_CODE",true);

startActivityForResults(intent,123)

and in your secondActivity

@Override

            public void success() {

                updateAccountSettings("");

                AccountSetupCheckSettings.actionCheckSettings(

                        AccountSetupIncoming.this, mAccount, 

                        CheckDirection.INCOMING);

                        setResults(RESULTS_OK);

                        finish();

            }

and in your firstactivity you can get the result in the activity's overrided method

@Override

    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent 

    data)

    {

    if(requestCode ==123 && resuldCode==RESULT_OK){

        //do taks

      }

    }
