android - Caused by: java.lang.IllegalStateException: ParsePlugins is already initialized

Question

I quit the app, relaunch it, I am getting an exception.

public void onCreate() {
-->here Parse.initialize(this, "adfsfasdfs",
            "asdfadfsdf");
    ParseInstallation.getCurrentInstallation().saveInBackground();
    ParseInstallation.create(identity == null ? "No Identity Set"
            : identity);

Exception

                <action android:name="com.parse.push.intent.OPEN" />
            </intent-filter>
        </receiver>

Edit :

I wonder why Parse would throw an exception for this. Why not just info and move on. Its initialized, so big deal if I initialized it again.

Solution

I have given up on Parse. Dont like the Application way, just to irritating to maintain.

Answer 1

Parse.initialize() should only be called once for an entire application.

Calling it in an Activity's onCreate function can cause it to be initialized more than once, as an Activity can be created more than once during an app's lifecycle.

Instead, create an Application class (and add an android:name attribute to your your application's manifest).

Application: (Note not an Activity/Service/Reciever)

//Note that this is an android.app.Application class.
public class MyApplication extends android.app.Application {

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

    //This will only be called once in your app's entire lifecycle.
    Parse.initialize(this,
            getResources().getString(R.string.parse_application_id),
            getResources().getString(R.string.parse_client_key));
}

AndroidManifest:

<application
        android:name=".MyApplication">
        ....
        <activity>
            ....
        </activity>
</application>
