Error loading listview of parse.com

Question

Hi, I’d like to know what I’m doing wrong, because I run the app and it always gives an error, giving a stop.

ListView listview;
List<ParseObject> ob;
ProgressDialog mProgressDialog;
ListViewAdapter adapter;
private List<WorldPopulation> worldpopulationlist = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    ...
new RemoteDataTask().execute();
}

// RemoteDataTask AsyncTask
private class RemoteDataTask extends AsyncTask<Void, Void, Void> {
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // Create a progressdialog
        mProgressDialog = new ProgressDialog(Ofertas.this);
        // Set progressdialog title
        mProgressDialog.setTitle("Carregando Ofertas");
        // Set progressdialog message
        mProgressDialog.setMessage("Aguarde...");
        mProgressDialog.setIndeterminate(false);
        // Show progressdialog
        mProgressDialog.show();
    }

    @Override
    protected Void doInBackground(Void... params) {
        // Create the array

        worldpopulationlist = new ArrayList<WorldPopulation>();
        try {

            // Locate the class table named "Country" in Parse.com
            ParseQuery<ParseObject> query = new ParseQuery<ParseObject>(
                    "Country");
            // Locate the column named "ranknum" in Parse.com and order list
            // by ascending
            query.orderByAscending("ranknum");
            ob = query.find();
            for (ParseObject country : ob) {
                // Locate images in flag column
                ParseFile image = (ParseFile) country.get("flag");


                WorldPopulation map = new WorldPopulation();
                map.setRank((String) country.get("rank"));
                map.setCountry((String) country.get("country"));
                map.setPopulation((String) country.get("population"));
                map.setFlag(image.getUrl());
                worldpopulationlist.add(map);
            }
        } catch (ParseException e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return null;
    }

   @Override

    protected void onPostExecute(Void result) {
        // Locate the listview in listview_main.xml
        listview = (ListView) findViewById(R.id.listView);
        // Pass the results into ListViewAdapter.java
        adapter = new ListViewAdapter(Ofertas.this,
                worldpopulationlist);
        // Binds the Adapter to the ListView
        listview.setAdapter(adapter);
        // Close the progressdialog
        mProgressDialog.dismiss();
    }

Answer 1

By mistake Didn't find class "bolts.Task" is saying that the class does not exist (did not find the class "bolts.Task"), it is likely that the package referring to the class was not added to the application, for that just add the package bolts-android

• Download of the Releases

There is a link called "Artifacts: Maven Central" below each Release, in it you find the version jar.

If you are using the Parse.com, you can follow this link: https://parse.com/apps/quickstart#parse_data/mobile/android/Native/existing

Installing the SDK

• Download and extract the SDK: https://parse.com/downloads/android/Parse/latest
• Be sure to be using Gingerbread (android-9) or higher.

• Add the SDK to your app from Android Studio:

  Drag the Parse-*.jar that you downloaded to your app in the "libs" folder and add to your build.gradle this:

  dependencies {
      compile 'com.parse.bolts:bolts-android:1.+'
      compile fileTree(dir: 'libs', include: 'Parse-*.jar')
  }
  

To the problem failed to make and chown /acct/uid_10063: Read-only file system

This error probably occurs because your virtual android is in read mode, or does not have a virtualized memory card (Sdcard), to resolve do this:

• Go to the woman .android virtual machines and search for the file config.ini, for example ~/.android/avd/adv1.avd/config.ini or on Windows C:\Users\cr\.android\avd\adv1.avd\config.ini

• Open the file with a text editor like Notepad++ or Sublimetext

• Change this line hw.sdCard=no for hw.sdCard=yes

• Save the file and restarted Androidstudio or Eclipse

• Open again and try to run your project

Answer 2

Thank you Guilherme Nascimento for the tips, I am new here and I just wanted to show how I had found the solution. Well, I found that it was necessary to add the name of Class Parseapplication inside Android Manifest.

<application
    android:name="ParseApplication"
    ....
