unable to find com.android.camera.CropImage activity in android

Question

I am trying to run PhotoStream sample from following link

Answer 1

Actually there are quite a few apps, which offer the CROP action in Android 2.x: the standard Gallery, or Flikie Wallpapers just to name a couple. Why resolving the intents successfully fails, is that Google changed the components which provide the API. In Android 1.x that might have been com.android.gallery, but since (I think) API9/Android 2.3.x the default gallery is provided by Cooliris, so it is something like com.cooliris.gallery, etc.

The correct way to resolve the intent on any phone is (code, which I use):

// this is something to keep our information
class CropOption
{
    CharSequence TITLE;
    Drawable ICON;
    Intent CROP_APP;
}

// we will present the available selection in a list dialog, so we need an adapter
class CropOptionAdapter extends ArrayAdapter
{
    private List _items;
    private Context _ctx;

    CropOptionAdapter(Context ctx, List items)
    {
        super(ctx, R.layout.crop_option, items);
        _items = items;
        _ctx = ctx;
    }

    @Override
    public View getView( int position, View convertView, ViewGroup parent )
    {
        if ( convertView == null )
            convertView = LayoutInflater.from( _ctx ).inflate( R.layout.crop_option, null );

        CropOption item = _items.get( position );
        if ( item != null )
        {
            ( ( ImageView ) convertView.findViewById( R.id.crop_icon ) ).setImageDrawable( item.ICON );
            ( ( TextView ) convertView.findViewById( R.id.crop_name ) ).setText( item.TITLE );
            return convertView;
        }
        return null;
    }
}

The layout for the item should be a horizontal linear layout with an IconView and a TextView. I will skip it for brevity's sake, by now you most probably know how to do it :-)

Now for the part where we find the intents and present them for selection (this is only the relevant part of the function, onActivityResult):

try
{
    final List cropOptions = new ArrayList();

    // this 2 lines are all you need to find the intent!!!
    Intent intent = new Intent( "com.android.camera.action.CROP" );
    intent.setType( "image/*" );

    List list = getPackageManager().queryIntentActivities( intent, 0 );
    if ( list.size() == 0 )
    {
        // I tend to put any kind of text to be presented to the user as a resource for easier translation (if it ever comes to that...)
        Toast.makeText( this, getText( R.string.error_crop_option ), Toast.LENGTH_LONG );
        // this is the URI returned from the camera, it could be a file or a content URI, the crop app will take any
        _captureUri = null; // leave the picture there
        break; // leave this switch case...
    }

    intent.setData( _captureUri );
    intent.putExtra( "outputX", 128 );
    intent.putExtra( "outputY", 128 );
    intent.putExtra( "aspectX", 1 );
    intent.putExtra( "aspectY", 1 );
    intent.putExtra( "scale", true );
    //intent.putExtra( "", true ); // I seem to have lost the option to have the crop app auto rotate the image, any takers?
    intent.putExtra( "return-data", true );

    for ( ResolveInfo res : list )
    {
        final CropOption co = new CropOption();
        co.TITLE = getPackageManager().getApplicationLabel( res.activityInfo.applicationInfo );
        co.ICON = getPackageManager().getApplicationIcon( res.activityInfo.applicationInfo );
        co.CROP_APP = new Intent( intent );
        co.CROP_APP.setComponent( new ComponentName( res.activityInfo.packageName, res.activityInfo.name ) );
        cropOptions.add( co );
    }

    // set up the chooser dialog
    CropOptionAdapter adapter = new CropOptionAdapter( this, cropOptions );
    AlertDialog.Builder builder = new AlertDialog.Builder( this );
    builder.setTitle( R.string.choose_crop_title );
    builder.setAdapter( adapter, new DialogInterface.OnClickListener() {
        public void onClick( DialogInterface dialog, int item )
        {
            startActivityForResult( cropOptions.get( item ).CROP_APP, ACTIVITY_CROP );
        }
    } );
    builder.setOnCancelListener( new DialogInterface.OnCancelListener() {
        @Override
        public void onCancel( DialogInterface dialog )
        {
            // we don't want to keep the capture around if we cancel the crop because we don't want it anymore
            if ( _captureUri != null )
            {
                getContentResolver().delete( _captureUri, null, null );
                _captureUri = null;
            }
        }
    } );
    AlertDialog alert = builder.create();
    alert.show();
}
catch ( Exception e )
{
    Log.e( TAG, "processing capture", e );
}

And there you have it... Hope that helps, I lost 2 days trying to figure it out...
