What steps will reproduce the problem?
1. Open my deck in Anki or Ankidroid
2. Sync it (the first time its working)
3. do some reviews
4. do a Sync in Ankidroid -> Error

What is the expected output? What do you see instead?
A message that sync was not succesfull.

What version of AnkiDroid are you using? On what version of Android?
0.5 beta 20

Please provide any additional information below.

This seems like a major problem but I couldn't find anything in searching.

On AnkiDroid I can use the flashcards fine but the pictures won't load in the flashcards.
The pictures load find on the flashcards on the desktop application. 
I have the .media folder and the .anki file in the same folder that is the pathway
for the AnkiDroid application. 
The image files are .png

Thanks for any help, I just started using Anki and this is a major setback.

Purpose / Description

Issue #5011 was especially thorny because to solve it properly meant to alter the way it handled storage by changing it from speculative persistence of edits to persistence of edits only when the user confirmed it.

Previous work altered related code (Previewer, some libanki APIs) to handle working with unsaved data, as well as tracking changes to it, and now it all comes together in this PR

As mentioned in the commit, it does not implement undo. I've done undo in #5113 so I know how, but this PR is already huge, and I believe this PR is still 100% of the feature profile of the previous code so it's not a regression.

This is based on #5150 (which itself chained to #5149 and #5148) so the commit list will whittle down as those are reviewed and merged, or this can go at once.

Fixes

Fixes #5011, #5600

How Has This Been Tested?

The automated testing is extremely thorough - 90% or higher for the new code - because this is a complicated Activity, and very important. I've also clicked around a bunch in an API28 emulator

Further work should include undo, maybe making the "don't orphan notes on template remove" check async, and investigating whether the pager fragment invalidation workaround is still necessary.

I haven't been too happy with the way the Icon looks right now, compared to other apps.

Part of the problem is that the shape that's supposed to represent a flashcard requires an additional background, which is a neutral white right now. So I took the previous SVG, cleaned it up (SVGs generated by Illustrator are quite the mess) and turned it into a square version without the shape, but maintaining all other elements exactly the way they were.

As an adaptive icon, it looks like this.

Because I thought some people would dislike the cut-off star, I reduced the star size and moved it a bit.

That's fine, but unfortunately the square version, which would still be visible in many launchers and possibly Google Play, doesn't look as attractive anymore in my opinion, because the star seems too small now.

The people I've asked so far actually seemed to prefer the first (unmodified) version with the cut-off star, because it makes the whole thing a bit more visually interesting and dynamic.

What do you think, does something like this have a chance of getting merged?

This is a pull request for a content provider as discussed here: https://groups.google.com/forum/#!msg/anki-android/SitMpj7J6fw/swqcuJKcld8J

It currently supports getting the unprocessed data from the Anki DB using the following URI: content://com.ichi2.anki.flashcard/flashcards

and fields and cards/decks using

content://com.ichi2.anki.flashcard/flashcards/<note_id>/data

The contract is described in FlashCardsContract.java. I release this file into the public domain so that it can be used by any third party software without any attribution or royalty. I.e. this file (and this file only) is not licensed under GPL.

The content provider currently only supports notes/cards, but not models.

It also only supports the query() function, no insert() or update() yet.

For update() on fields I intended to use the same mechanism as NoteEditor, but there is some kind of check that prevents updates from any other Thread than the main thread.

The first intention of this PR is to discuss if the proposed data structure is acceptable/understandable for the AnkiDroid developers and to discuss implementation details such as the above (concerning the main thread problem). Of course, I hope that it will later merged into the main branch.

Reproduction Steps

1. Select deck to review
2. Question page is nearly blank (only note and "show answer" button)
3. Right answer page is also blank

See pictures:

Expected Result

Question and answer page should be as usual, with the buttons there.

This is a major performance improvement for inserting large numbers (hundreds or thousands) of Notes.

Added support for bulkInsert() to the content provider as well as the API (addNewNotes). This will work with existing provider but new provider implementation is much faster.

Added support for inserting a new note into a deck with one provider call (instead of three in existing API implementation) to the provider's insert() method. Again, this will work with existing provider, but new provider implementation is about 39% faster.

Added API support for updating an existing note: updateNote() and updateNoteTags(). (This is already supported by existing provider).

Added API support for counting number of notes (with a certain model id) in a deck: countNotes(). I couldn't see a way to count notes in a deck while ignoring model id. (This is already supported by existing provider).

Added provider support for "count(*)" column in projection.

Added a meta-data key to the provider (in manifest) so that the API can query whether the provider supports these new features.

Here are the stats from my testing on a Nexus 6P (6.0.1):

Insert 2122 notes (same model (three fields), same deck, single card)

Ankidroid v.20600116 (3 provider calls per note): 191secs Rewrote as single provider call per note: 138secs Rewrote as single provider call in total (bulk insert): 119secs

This PR: single provider call in total (bulk insert, single transaction): Ignore duplicates (empty deck): 44secs Ignore duplicates (deck already contains 2122 notes, so none added): 34secs No duplicate check (empty deck): 8.5secs

You can delete the card, deck, etc, but when you use the same expression, it still
fails the same. The generated image is in the sd card as it should be, and everything
is working properly on the desktop client (rc3).

I note that although the below expression fails consistently, I believe I have seen
others fail on occasion, but they appear to work now after deleting, syncing, etc.

For me, it's failing on this expression:
[$$]E_{n} = E_{total} \frac{R_{n}}{R_{total}}[/$$]

Ad Requirements

It must be an advertisement soliciting the participation and contribution of programmers writing actual source code. This is not intended as a general purpose ad for consumer products which just happen to be open source. It's for finding programmers who will help contribute code or other programmery things (documentation, code review, bug fixes, etc.).

Your ad should be an original creation which has not previously appeared on Stack Overflow. Please do not resubmit entries that have appeared as ads on Stack Overflow in previous periods.

In order to work, the answers you post to this question must conform to the following rules.

Image requirements

• The image that you create must be 300 pixels by 250 pixels, or twice that if high DPI.
• Must be hosted through our standard image uploader (imgur)
• Must be GIF or PNG
• No animated GIFs
• Absolute limit on file size of 150 KB
• Must have a 1px border if (part of) the background is white, 2px if the image is high DPI.

The output, which ultimately will be served in an ad slot on Stack Overflow, can be previewed by clicking through to this URL:

I believe that we'll need to ask the authors to release the images under the GNU General Public License, so they can be distributed with the project.

It'd be useful to get a few prospect ads, one for this half of the year, and ideally a backlog so we can register as soon as the next one is out.
