I am trying to implement Disk based image lru cache with jake wharton DiskLruCache library. link to library. I am using a code snippet from here.
Methods i am having trouble with are this
private boolean writeBitmapToFile(Bitmap bitmap, DiskLruCache.Editor editor)
throws IOException, FileNotFoundException {
OutputStream out = null;
try {
out = new BufferedOutputStream(editor.newOutputStream(0), Utils.IO_BUFFER_SIZE);
return bitmap.compress(mCompressFormat, mCompressQuality, out);
} finally {
if (out != null) {
out.close();
}
}
}
where editor.newOutputStream(0) does not exist, and this one
public Bitmap getBitmap(String key) {
Bitmap bitmap = null;
DiskLruCache.Snapshot snapshot = null;
try {
snapshot = mDiskCache.get(key);
if (snapshot == null) {
return null;
}
final InputStream in = snapshot.getInputStream(0);
if (in != null) {
final BufferedInputStream buffIn =
new BufferedInputStream(in, Utils.IO_BUFFER_SIZE);
bitmap = BitmapFactory.decodeStream(buffIn);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (snapshot != null) {
snapshot.close();
}
}
Log.d("cache_test_DISK_", bitmap == null ? "" : "image read from disk " + key);
return bitmap;
}
where snapshot.getInputStream(0) also does not exist.
What am i doing wrong? I have placed the jar with the library and all is well, are these methods deleted from DiskLruCache library? Is there other way to do this now? I can't find any examples or tutorials.
Library version is the latest disklrucache-2.0.2
Make sure you have imported the right class:
import com.jakewharton.disklrucache.DiskLruCache
