Hi there,
I'm writing an podcast playing application. The application has pre-
defined feeds but I want to cache the image of the feed for 30 days.
However, on the initial creation of the podcast I am downloading the
image, and trying to save it to the SD card using the code below:
public long createPodcast(RssFeed feed, String feedUrl) {
ContentValues insertValues = new ContentValues();
insertValues.put(KEY_FEED_TITLE, feed.title);
insertValues.put(KEY_FEED_FEED_URL, feedUrl);
insertValues.put(KEY_FEED_LINK, feed.link);
insertValues.put(KEY_FEED_DESCRIPTION, feed.description);
insertValues.put(KEY_FEED_PUBDATE, feed.pubDate);
insertValues.put(KEY_FEED_IMAGE_URL, feed.imageUrl);
insertValues.put(KEY_FEED_IMAGE_WIDTH, feed.imageWidth);
insertValues.put(KEY_FEED_IMAGE_HEIGHT, feed.imageHeight);
insertValues.put(KEY_FEED_SUBSCRIBED, false);
long rowId = mDb.insert(TABLE_PODCAST_LIST, null,
insertValues);
String storage_state = Environment.getExternalStorageState
();
if (storage_state.contains("mounted")) {
File f = Environment.getExternalStorageDirectory();
File j = new File(f, "twitcast");
try {
URL users_avatar = new URL(feed.imageUrl);
HttpURLConnection conn = (HttpURLConnection)
users_avatar.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
Bitmap bmImg = BitmapFactory.decodeStream(is);
File k = new File(j, rowId + ".jpg");
k.mkdirs();
k.createNewFile();
FileOutputStream fos = new FileOutputStream(k);
bmImg.compress(Bitmap.CompressFormat.JPEG, 100,
fos);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return rowId;
}
However, it keeps failing on the line k.createNewFile(); with the
error:
WARN/System.err(10727): java.io.IOException: Parent of file is not a
directory: /sdcard/twitcast/1.jpg
I've checked and I have write permission and the SD card is mounted,
and I have android.permission.MOUNT_UNMOUNT_FILESYSTEMS included in my
manifest.
Does anyone have any ideas why this keeps failing?
Thanks,
Tane Piper
