Solved Array Issue, App Disappearance and Force Close Error, but still no videos, where is the flaw in this code??

Question

After having solved every of my previous issues to get the code running for retrieving videos from the sdcard and displaying them in the GridView, I still cannot see the videos. I don't know what I have done wrong that they won't show and the array isn't passed on.

If someone could help me out, please, because I really haven't got a clue what's wrong... :(( Thank you...

This is the java file that tries to retrieve and display the videos from the sdcard in the GridView:

package com.mobilevideoeditor.moved;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.VideoView;




public class EditGalleryView extends Activity {
    Uri[] vidUris;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.videogrid);

        GridView vGrid=(GridView) findViewById(R.id.vgrid);
        vGrid.setAdapter(new VideoAdapter(this));

        Uri uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;

        Log.d("EditGalleryView", "uri:"+uri);
        String[] projection = {
                MediaStore.Video.Media.DESCRIPTION,
                MediaStore.Video.Media.DATA  
    };

        Cursor c = this.managedQuery(uri, projection, null, null,
                MediaStore.Video.Media.DATE_ADDED);
                         Log.d("EditGalleryView", "vids available:" +c.getCount());

                         ArrayList<Uri> experimentVids = new ArrayList<Uri>();


                             if (c.getCount() != 0) {

                                 experimentVids.add(Uri.parse(c.getString(1)));

Answer 1

Make vidUris a member of the EditGalleryView class. Also I think there is a toArray method on ArrayList that will return an array of elements.
