Android : Issue while Caching the image in Disk

Am currently developing a custom gallery where am using DiskLruCache ..Unfortunately, while am running am getting the following error

java.lang.IllegalStateException: edit didn't create file 1

here is my code for caching image to disk

public void addBitmapToCache(String data, BitmapDrawable value) {
            //BEGIN_INCLUDE(add_bitmap_to_cache)
            if (data == null || value == null) {
                return;
            }

            // Add to memory cache
            if (mMemCache != null) {
                if (RecyclingBitmapDrawable.class.isInstance(value)) {
                    // The removed entry is a recycling drawable, so notify it
                    // that it has been added into the memory cache
                    ((RecyclingBitmapDrawable) value).setIsCached(true);
                }
                mMemCache.put(data, value);
            }

            synchronized (mDiskCacheLock) {
                // Add to disk cache
                if (mDiskLruCache != null) {
                    final String key = DiskLruCache.hashKeyForDisk(data);
                    OutputStream out = null;
                    try {
                        DiskLruCache.Snapshot snapshot = mDiskLruCache.get(key);
                        if (snapshot == null) {
                            final DiskLruCache.Editor editor = mDiskLruCache.edit(key);
                            if (editor != null) {
                                out = editor.newOutputStream(0);
                                value.getBitmap().compress(CompressFormat.JPEG, 100, out);
                                editor.commit();
                                out.close();
                            }
                        } else {
                            snapshot.getInputStream(0).close();
                        }
                    } catch (final IOException e) {
                        Log.e("disk", "addBitmapToCache - " + e);
                    } catch (Exception e) {
                        Log.e("disk", "addBitmapToCache - " + e);
                    } finally {
                        try {
                            if (out != null) {
                                out.close();
                            }
                        } catch (IOException e) {}
                    }
                }
            }

     }

why am getting this error and what is the solution for this?
