Android - ParseObject Id is Null

Question

Could anyone please help me with this issue. I have 2 activities for user to register their profile. I created a ParseObject user then pass this user object to the second activity. I used user.getObjectId() to get the ID of user object, but the ID is always null. I wonder if anyone could help me find the ParseObject's user ID. Please see my code below. Thank you

public class RegisterActivity extends Activity {

protected EditText mFirstName;
protected EditText mMiddleName;
protected EditText mLastName;
protected EditText mUserEmail;
protected EditText mPhoneNumber;
protected EditText mAddressLine1;
protected EditText mAddressLine2;
protected EditText mEmergencyName;
protected EditText mEmergencyPhone;
protected EditText mEmergencyRelationship;
protected EditText mEmergencyOtherInfo;
protected Button mNextPageButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_register);

    //Parse.enableLocalDatastore(this);
    Parse.initialize(this, "XXXXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXX");

    //Initialize
    mFirstName = (EditText)findViewById(R.id.firstNameRegisterEditText);
    mMiddleName = (EditText)findViewById(R.id.middleNameRegisterEditText);
    mLastName = (EditText)findViewById(R.id.lastNameRegisterEditText);
    mUserEmail = (EditText)findViewById(R.id.emailRegisterEditText);
    mPhoneNumber = (EditText)findViewById(R.id.phoneRegisterEditText);
    mAddressLine1 = (EditText)findViewById(R.id.addressRegisterText);
    mAddressLine2 = (EditText)findViewById(R.id.address2RegisterText);
    mEmergencyName = (EditText)findViewById(R.id.emergencyNameEditText);
    mEmergencyPhone = (EditText)findViewById(R.id.emergencyPhoneEditText);
    mEmergencyRelationship = (EditText)findViewById(R.id.emergencyRelationshipEditText);
    mEmergencyOtherInfo = (EditText)findViewById(R.id.medicalInfoEditText);
    mNextPageButton = (Button)findViewById(R.id.nextPageButton);

    //Listen to register button click
    mNextPageButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Get first name, middle name, last name, user email, phone number, address line 1, address line 2,
            //emergency name, emergency phone, emergency relationship, emergency other info and convert them to string
            String firstName = mFirstName.getText().toString().trim();
            String middleName = mMiddleName.getText().toString().trim();
            String lastName = mLastName.getText().toString().trim();
            String userEmail = mUserEmail.getText().toString().trim();
            String phoneNumber = mPhoneNumber.getText().toString().trim();
            String addressLine1 = mAddressLine1.getText().toString().trim();
            String addressLine2 = mAddressLine2.getText().toString().trim();
            String emergencyName = mEmergencyName.getText().toString().trim();
            String emergencyPhone = mEmergencyPhone.getText().toString().trim();
            String emergencyRelationship = mEmergencyRelationship.getText().toString().trim();
            String emergencyOtherInfo = mEmergencyOtherInfo.getText().toString().trim();

            //String password = mUserPassword.getText().toString().trim();

            ParseObject user = new ParseObject("User");

            //Store user in parse
            user.put("firstName", firstName);
            user.put("middleName", middleName);
            user.put("lastName", lastName);
            user.put("email", userEmail);
            user.put("phoneNumber", phoneNumber);
            user.put("addressLine1", addressLine1);
            user.put("addressLine2", addressLine2);
            user.put("emergencyName", emergencyName);
            user.put("emergencyPhone", emergencyPhone);
            user.put("emergencyRelationship", emergencyRelationship);
            user.put("otherInfo", emergencyOtherInfo);
            user.put("username", userEmail);

            user.saveInBackground();

            //Passing user object to AppearanceActivity and take user to appearance register page
            Intent intent = new Intent(RegisterActivity.this, AppearanceActivity.class);
            intent.putExtra("user_id", user.getObjectId());
            startActivity(intent);
        }
    });
}

String firstName = mFirstName.getText().toString().trim();
        String middleName = mMiddleName.getText().toString().trim();
        String lastName = mLastName.getText().toString().trim();
        String userEmail = mUserEmail.getText().toString().trim();
        String phoneNumber = mPhoneNumber.getText().toString().trim();
        String addressLine1 = mAddressLine1.getText().toString().trim();
        String addressLine2 = mAddressLine2.getText().toString().trim();
        String emergencyName = mEmergencyName.getText().toString().trim();
        String emergencyPhone = mEmergencyPhone.getText().toString().trim();
        String emergencyRelationship = mEmergencyRelationship.getText().toString().trim();
        String emergencyOtherInfo = mEmergencyOtherInfo.getText().toString().trim();

        //String password = mUserPassword.getText().toString().trim();

        final ParseObject user = new ParseObject("User");

        //Store user in parse
        user.put("firstName", firstName);
        user.put("middleName", middleName);
        user.put("lastName", lastName);
        user.put("email", userEmail);
        user.put("phoneNumber", phoneNumber);
        user.put("addressLine1", addressLine1);
        user.put("addressLine2", addressLine2);
        user.put("emergencyName", emergencyName);
        user.put("emergencyPhone", emergencyPhone);
        user.put("emergencyRelationship", emergencyRelationship);
        user.put("otherInfo", emergencyOtherInfo);
        user.put("username", userEmail);

        user.saveInBackground(new SaveCallback() {
            public void done(ParseException e) {
                if (e == null) {
                    // Saved successfully.
                    //Passing user object to AppearanceActivity and take user to appearance register page
                    Intent intent = new Intent(RegisterActivity.this, AppearanceActivity.class);
                    intent.putExtra("user_id", user.getObjectId());
                    startActivity(intent);
                } else {
                    // The save failed.
                    Log.d("", "User update error: " + e);
                }
            }
        });

First some general remarks when working with Parse :

Parse.initialize(this, "XXXXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXX");

Should happen in the OnCreate hook of your Application not an Activity instance.

ParseObject#saveInBackground is asynchronous. Thus it renders waiting for the objectId to update useless. You can provide a Callback function to your save call which will be called when the saving has finished!

Nonetheless I am pretty sure you want to Register a user (since the Name of the RegisterActivity indicates that), so why don't you simply use this example :

ParseUser user = new ParseUser();
user.setUsername("my name");
user.setPassword("my pass");
user.setEmail("email@example.com");

// other fields can be set just like with ParseObject
user.put("phone", "650-253-0000");

user.signUpInBackground(new SignUpCallback() {
  public void done(ParseException e) {
    if (e == null) {
      // Hooray! Let them use the app now.
    } else {
      // Sign up didn't succeed. Look at the ParseException
      // to figure out what went wrong
    }
  }
});

Please also make sure to read the official docs before getting to code something which may already have been taken care off. Especially for your use case you might find this useful !

I don't know for sure if this will fix your problem, but I think you need to use ParseUser to work with users, not ParseObject.
