Answer 1

public static String getThumbnailPath(Context context, String path)
{
  long imageId = -1;

  String[] projection = new String[] { MediaStore.MediaColumns._ID };
  String selection = MediaStore.MediaColumns.DATA + "=?";
  String[] selectionArgs = new String[] { path };
  Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, selection, selectionArgs, null);
  if (cursor != null && cursor.moveToFirst())
  {
    imageId = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
    cursor.close();
  }

  String result = null;
  cursor = MediaStore.Images.Thumbnails.queryMiniThumbnail(context.getContentResolver(), imageId, MediaStore.Images.Thumbnails.MINI_KIND, null);
  if (cursor != null && cursor.getCount() > 0)
  {
    cursor.moveToFirst();
    result = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
    cursor.close();
  }

  return result;
}

Answer 2

Based on @Karan's answer and following comments, just for the people that arrive here (like I did) and need a ready-to-work code:

public String getThumbnailPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media._ID };
    String result = null;
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media._ID);

    cursor.moveToFirst();
    long imageId = cursor.getLong(column_index);
    cursor.close();

    cursor = MediaStore.Images.Thumbnails.queryMiniThumbnail(
            getContentResolver(), imageId,
            MediaStore.Images.Thumbnails.MINI_KIND,
            null);
    if (cursor != null && cursor.getCount() > 0) {
        cursor.moveToFirst();
        result = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
        cursor.close();
    }
    return result;
}

Answer 3

It could be a alternative ways as other had already mentioned in their answer but Easy way i found to get thumbnail is using ExifInterface

ExifInterface exif = new ExifInterface(pictureFile.getPath());
byte[] imageData=exif.getThumbnail();
Bitmap  thumbnail= BitmapFactory.decodeByteArray(imageData,0,imageData.length);

Answer 4

Two variants without depricated methods.

 public String getThumbnailPath(Uri uri) {
    String[] proj = { MediaStore.Images.Media.DATA };

    // This method was deprecated in API level 11
    // Cursor cursor = managedQuery(contentUri, proj, null, null, null);

    CursorLoader cursorLoader = new CursorLoader(activity, uri, proj, null, null, null);
Cursor cursor = cursorLoader.loadInBackground();

    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);

    cursor.moveToFirst();
    long imageId = cursor.getLong(column_index);
    //cursor.close();
    String result="";
    cursor = MediaStore.Images.Thumbnails.queryMiniThumbnail(activity.getContentResolver(), imageId,
            MediaStore.Images.Thumbnails.MINI_KIND, null);
    if (cursor != null && cursor.getCount() > 0) {
        cursor.moveToFirst();
        result = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
        cursor.close();
    }
    return result;
}
public Bitmap getThumbnailBitmap(Uri uri){
    String[] proj = { MediaStore.Images.Media.DATA };

    // This method was deprecated in API level 11
    // Cursor cursor = managedQuery(contentUri, proj, null, null, null);

    CursorLoader cursorLoader = new CursorLoader(activity, uri, proj, null, null, null);
    Cursor cursor = cursorLoader.loadInBackground();

    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);

    cursor.moveToFirst();
    long imageId = cursor.getLong(column_index);
    //cursor.close();

    Bitmap bitmap = MediaStore.Images.Thumbnails.getThumbnail(
            getContentResolver(), imageId,
            MediaStore.Images.Thumbnails.MINI_KIND,
            (BitmapFactory.Options) null );

    return bitmap;
}

Answer 5

Take a look at the following class

Answer 6

The accepted answer is not working for me. I use following method to make it:

    try{
        Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getActivity().getContentResolver(), uri);
        Bitmap thumbBitmap = ThumbnailUtils.extractThumbnail(bitmap,120,120);
        // imageView.setImageBitmap(thumbBitmap);
    }
    catch (IOException ex){
        //......
    }
