您必须在实例化之前注册此ParseObject子类

Question

I am getting the following error in my Android application using Parse :

You must register this ParseObject subclass before instantiating it.

In my Application object, I am doing the following inside onCreate :

Parse.enableLocalDatastore(this);
Parse.initialize(this, "code", "code");

So why am I still getting this error? It was working fine yesterday but it's all of a sudden stopped working.

This is my Manifest file:

 <application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        ....

LogCat:

 java.lang.IllegalArgumentException: You must register this ParseObject subclass before instantiating it.

Answer 1

You must call ParseObject.registerSubclass(YourClassName.class); before calling Parse.initialize() .

In addition, you need to annotate your custom class like this:

@ParseClassName("YourClassName")
public class YourClassName extends ParseObject
{
}

Finally, your custom class needs a default no-args constructor in order to be registered by ParseObject .

Answer 2

You also have to put it in your Manifest like this:

 <application
        android:name="ParseApplication"
        android:allowBackup="true"
        android:icon="@drawable/logo"
        android:label="@string/app_name"         
        android:theme="@style/AppTheme" >

<activity
YOUR ACTIVITY 1
           />
  <activity
YOUR ACTIVITY 2
           />
</application>

And then try swapping these following lines

Parse.enableLocalDatastore(this);
Parse.initialize(this, "key", "key");

like this:

 Parse.initialize(this, "key", "key");
 Parse.enableLocalDatastore(this);
