meta user

[agungR]

Hi Cubeacon, i stiil newbie on android programming i have a problem putting on script for meta user. i saw on backend it can place #fullname for notification. but when i try running on application it just say "there". i saw this script on cubeacon guide.

CBUser.setUserData("User fullname", "User valid email"); CBUser.currentUser().sendDataInBackground(new Callback() { @Override public void onCompleted(Exception exp) { if (exp == null) // show succesfull message else // show error message by exp.getMessage() } }); where to put this and how to use it.

Hi @agungR ,

You can put that code on your activity. After successfully set your username, you can enable and set your notification text with Personal Notification on Cubeacon Developer

Hi @alann-maulana , i use this in my activity

public class InputActivity extends Activity {
    private EditText name, email;
    private Button save;
    private Context context;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        context = this.getApplicationContext();

        name = (EditText) findViewById(R.id.editName);
        email = (EditText) findViewById(R.id.editEmail);
        save = (Button) findViewById(R.id.saveBtn);

        save.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                CBUser.setUserData("User fullname", "User valid email");
                CBUser.currentUser().sendDataInBackground(new Callback() {
                    @Override
                    public void onCompleted(Exception exp) {
                        if (exp == null) {
                            Intent intent = new Intent(InputActivity.this,
                                    SplashActivity.class);
                            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                            startActivity(intent);
                        } else {
                            Log.e("InputActivity", exp.getMessage());
                            }

                        }
                });

Hi @agungR

First you need to extends your activity class that used to scan beacon to CBActivity class. Read our complete tutorials here. Thanks.
