Why Custom ArrayAdapter of my android application is not showing image?

Question

I have made an android application where image will save to local database when the network is unavailable. I am keeping image uri inside database table and retrieving image from image uri and showing that image on imageView of a listView using Custom array adapter. When I am running my application with emulator, it is working well. However while using an android mobile phone it showing Forced Close error.

The error log is given below:

MY Custom adapter is given below:

public class NoteListAdapter extends  ArrayAdapter<ImageFromDB> {
Context c;

ArrayList<ImageFromDB> image = null;
ArrayList<String> uriImage = null;
ArrayList<Integer> ID = null;

private AllId allid = null;
DBAdapter db = null;

WatchListAllEntity watchListAllEntity=null;
int flagVariable=1;
private ArrayList<ImageFromDB> items;

public NoteListAdapter(Context context, int textViewResourceId,
        ArrayList<ImageFromDB> items) {

    super(context, textViewResourceId, items);
    Log.e("sf","123");
    this.items = items;
    c=context;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;

    final int myPosition = position;
    if (v == null) {
        LayoutInflater vi = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.listitempict2, null);
    }
    ImageFromDB re = items.get(position);
    Log.e("re", re+"");
    if (re != null) {
        ImageView tt = (ImageView) v.findViewById(R.id.imageviewproduct);
        String imageUri = re.getImageuri();
        Log.e("imageUri", imageUri+"");
        tt.setImageURI(Uri.parse(imageUri));

        final CheckBox checkBox = (CheckBox) v.findViewById(R.id.checkboxproduct);
        checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {

                if (isChecked) {
                    if(flagVariable==1)
                    {
                        String ImUri = items.get(myPosition).getImageuri();
                        allid.setImageUri(ImUri);
                        allid.setId(items.get(myPosition).getId());
                        flagVariable++;
                        Log.e("flagVariable  : " , flagVariable+"");
                    }
                    else
                    {
                        checkBox.setChecked(false);
                        //Toast.makeText(Syncho2.this,"正しく選んでください。",Toast.LENGTH_SHORT).show();
                    }
                } else {
                    flagVariable=1;
                    Log.e("flagVariable  : " , flagVariable+"");
                }
            }
        });
    }
    return v;
}
}

I am calling this Adapter from a activity like this:

noteListAdapter = new NoteListAdapter(this, R.layout.listitempict, image);

I noticed from debug, the Adapter is being called six times when the image is only two . Five times it's returning a view but on the sixth time it is showing that error.

Read this: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html and you'll be able to load your image without any error!

i'm sure that compressing the bitmap will not fully help in this case - the app will forceclose not on the sixs' time but on the 16s' (for exmaple) =)

It's not about the compressing, it's about loading a scaled down version of the image. On the scree you don't need to display a 8Mp image. Just load the image scaled down to your screen size.

"I noticed from debug ,the Adapter is calling six times when the image is only two" - as you see even if he make this images smaller the problem is not only in scaled image, it will help only not to fall on the sixs' step - but it will forceclose after some time.

 public View getView(int position, View convertView, ViewGroup parent) {        

        View row = convertView;
     // if it's not recycled, initialize some attributes
        if (row == null) {  
            LayoutInflater li = (LayoutInflater)   mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
            row = li.inflate(R.layout.menucategory, null);          
            //imageView.setLayoutParams(new GridView.LayoutParams(85, 85));         
        }
            // getCategoryItem          
            Category  category = (Category) getItem(position);
            // Get reference to ImageView
            categoryIcon = (ImageView) row.findViewById(R.id.category_image);
            //categoryIcon.setLayoutParams(new GridView.LayoutParams(85, 85));
            categoryIcon.setScaleType(ImageView.ScaleType.CENTER_CROP);
            categoryIcon.setPadding(5, 5, 5, 5);

            categoryName = (TextView) row.findViewById(R.id.category_name);
            //Set category name
            categoryName.setText(category.getCategoryName());           


            if(category.getCategoryPath() != null){             
                    Bitmap bitmap = BitmapFactory.decodeFile(category.getCategoryPath());
                    System.out.println("bitmap2::  "+ bitmap);
                    if(bitmap != null){
                     categoryIcon.setImageBitmap(bitmap);
                    }               
            }                              

        return row;
    }

I have found a solution . I thing everybody should know about memory management of android application. http://www.youtube.com/watch?v=_CruQY55HOk . When I am trying to show image Uri directly on ImageView then the problem is creating . I thing everybody should avoid code like this ImageView.setImageURI(Uri.parse(imageUri)) . Instead of that, try to load bitmap or drawable on imageview.
