Parse crash on creating user

Question

I am using Parse as my backend for my Android app. I have a crash report for only some android devices when I try to create a User object. The error on the crash is:

Caused by: java.lang.IllegalArgumentException: 
You must register this ParseObject subclass before instantiating it.
at com.parse.ParseObject.<init>(ParseObject.java:184)

The devices that submitted the crash report are:

HTC Desire 510 (htc_a11ul)  2   33.3% Android 4.4
Xperia E3 (D2203)   1   16.7%  Android 4.4
Galaxy S4 (jflte)   1   16.7%  Android 4.4
Galaxy S5 (klte)    1   16.7%  Android 4.4

This is extremely odd as I currently have tested my code on the Samsung Note 4, Galaxy S4, S5, and Nexus 5 without any issues. I am not sure why Parse is asking me to subclass out of nowhere as I am not trying to use the subclass functionality offered by Parse. Again, I've tested this code on other devices without any issues.

Can someone please tell me how to fix this? I have included the code below where I create the User and it crashes.

Thank you!

    Parse.initialize(this, "XXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXX");
    ParseUser user = new ParseUser();
    user.setUsername(email);
    user.setPassword(confirmPassword);
    user.setEmail(email);
    user.put("deviceID", deviceID);
    user.put("name", fullName);

    progress = new ProgressDialog(Register.this);
    progress.setMessage("Creating Account... Please Wait");
    progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    progress.setIndeterminate(true);
    progress.setCanceledOnTouchOutside(false);
    progress.setCancelable(false);
    progress.show();


    user.signUpInBackground(new SignUpCallback() {
        public void done(ParseException e) {
            if (e == null) {
                // Hooray! Let them use the app now.
                Intent i = new Intent(Register.this, DeviceSettingsIntro.class);
                startActivity(i);
                progress.hide();
                btnRegister.setEnabled(true);
            } else {
                // Sign up didn't succeed. Look at the ParseException
                // to figure out what went wrong
                progress.hide();
                checkParseError(e);
                btnRegister.setEnabled(true);
            }
        }
    });

Answer 1

Have you tried initializing Parse using an Application class as described by Parse quick start guide? Maybe Parse wasn't initialized successfully

Create a class that extends Application, and for the content:

@Override
public void onCreate() {
    super.onCreate();

    Parse.enableLocalDatastore(this); //might not be needed
    Parse.initialize(this, "xxxxxxxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxx");
}

Edit your manifest < application > tag, add this:

    android:name="com.yourpackage.applicationclass"

//so it should look like (for example) : 
<application
    android:name="com.yourpackage.yourapplicationclass"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    //put activities here

</application>

This way, Parse will always be initialized when your Application launches, regardless of Activity.

You can try register the ParseUser class before calling Parse.initialize(), like this:

ParseObject.registerSubclass(ParseUser.class);
Parse.initialize();

I know you don't need to do this, but may be a work around for your problem. You can test and post the results!

Otherwise you can always look for more info with the parse team.
