In Topic: errors trying to use loaders in android

10 April 2013 - 09:58 AM

Well, I fixed the error on public Loader<OAuthConsumer> onCreateLoader by replacing it with public android.support.v4.content.Loader onCreateLoader.


I also fixed the error on new getCommonsHttpOAuthConsumer(); by replacing private Loader<OAuthConsumer> consumerLoader; with private getCommonsHttpOAuthConsumer consumerLoader;


I don't know if it's right tho

Double-check that import android.app.LoaderManager does not appear in any of your files.  After verifying that it isn't present, rebuild the files.



If the problem still persists, post the relevant updated code.

MainActivity is the only activity present in my app, so import android.app.LoaderManager is not written anywhere else.

Could it be because my target sdk version is 16? My minimum sdk version is 10. I doubt it, since changing those values doesn't fix the errors.


Here's the code for my main activity. I removed anything that didn't have to do with the problem. Tell me if you want the whole thing:

import oauth.signpost.OAuth;
import oauth.signpost.OAuthConsumer;
import oauth.signpost.OAuthProvider;
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;
import oauth.signpost.commonshttp.CommonsHttpOAuthProvider;
import twitter4j.Status;
import twitter4j.Twitter;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import twitter4j.auth.AccessToken;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.Loader;
import android.content.SharedPreferences;
import android.net.Uri;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v4.content.AsyncTaskLoader;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import android.support.v4.app.LoaderManager;
//import android.app.LoaderManager;

public class MainActivity extends Activity implements android.support.v4.app.LoaderManager.LoaderCallbacks{

	final String TAG = getClass().getName();
	private OAuthConsumer consumer;
        private OAuthProvider provider;
        private String token;
        private String secret;
        private Loader<OAuthConsumer> consumerLoader;
        Activity context;
	protected void onCreate(Bundle savedInstanceState) {
	    Button signInButton = (Button) findViewById(R.id.signInButton);
            signInButton.setOnClickListener(new View.OnClickListener() {
	        public void onClick(View v) {
	        	// TODO Auto-generated method stub

	public void sign_in()
    	    try {
    	        this.consumer = (OAuthConsumer) new getCommonsHttpOAuthConsumer(context);    	    
    	    } catch (Exception e) {
    	        Log.e(TAG, "Error creating consumer / provider",e);
	public boolean onCreateOptionsMenu(Menu menu) {
	    // Inflate the menu; this adds items to the action bar if it is present.
	    getMenuInflater().inflate(R.menu.activity_main, menu);
	    return true;
        public Loader<OAuthConsumer> onCreateLoader(int id, Bundle arg1) {
            consumerLoader = new getCommonsHttpOAuthConsumer();
            return consumerLoader;

class getCommonsHttpOAuthConsumer extends AsyncTaskLoader<OAuthConsumer>{

	public getCommonsHttpOAuthConsumer(Context context) {
	    // TODO Auto-generated constructor stub

	public OAuthConsumer loadInBackground() {
	    // TODO Auto-generated method stub
	    return new CommonsHttpOAuthConsumer(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);

For your errors, you need to return the right type.  Make sure your class extends the Loader class that matches the same interface (android.support.v4.content.Loader).  

I'm already doing that: public class MainActivity extends Activity implements LoaderManager.LoaderCallbacks


is that what you mean?
