    copied!<p>i am trying to get the images into a gridview from the sdcard, but i just want to get ONLY the CAMERA files. So this is my code:</p> <pre><code>public class GrillaActivity extends Activity { private Cursor imagecursor, actualimagecursor; private int image_column_index, actual_image_column_index; GridView imagegrid; private int count; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.grid_view); init_phone_image_grid(); } private void init_phone_image_grid() { String[] img = { MediaStore.Images.Thumbnails._ID }; imagecursor = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, MediaStore.Images.Thumbnails.DATA + "='/sdcard/DCIM/Camera/*.*'", null, MediaStore.Images.Thumbnails.IMAGE_ID + ""); image_column_index = imagecursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID); count = imagecursor.getCount(); imagegrid = (GridView)findViewById(R.id.PhoneImageGrid); imagegrid.setAdapter(new ImageAdapter(getApplicationContext())); imagegrid.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { System.gc(); String[] proj = { MediaStore.Images.Media.DATA }; actualimagecursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj, MediaStore.Images.Media.DATA + "='/sdcard/DCIM/Camera/*.*'", null, null); actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); actualimagecursor.moveToPosition(position); String i = actualimagecursor.getString(actual_image_column_index); System.gc(); Intent objI = getIntent(); objI.putExtra("clickedFile", i); setResult(100, objI); finish(); } }); } public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return count; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position,View convertView,ViewGroup parent) { System.gc(); ImageView i = new ImageView(mContext.getApplicationContext()); if (convertView == null) { imagecursor.moveToPosition(position); int id = imagecursor.getInt(image_column_index); i.setImageURI(Uri.withAppendedPath( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + id)); i.setScaleType(ImageView.ScaleType.CENTER_CROP); i.setLayoutParams(new GridView.LayoutParams(92, 92)); } else{ i = (ImageView) convertView; } return i; } } </code></pre> <p>}</p> <p>I had added a SELECTION in the managedQuery function, but i'm getting an error. So please help me, maybe i'm doing something wrong. Thanks in advance.</p>
