Sudoku Solver for Android

	Welcome to the project page for the SudokuWiki Solver app for Android. Now on version 1.62 - 3rd of March	Search for "SudokuWiki" $1.99
	Now in stores	Search for "Sudoku Solver" $1.99

3-Mar-2013
I've uploaded version 1.62 today. Responding to user requests, the app now allows candidates to be turned off (which makes it more like a player) and for tablets and large screens you can go to preferences an unlock landscape mode (for the solver page). Some interface touch ups and minor bugs fixed. See more at the end of the development page.

Approved on Google Play (World-wide)
Approved on Amazon.com (seems to be just USA at the moment)
Please leave a review. I'd love to hear your feedback. Any issues email me directly - bugs are easy to fix.
The build log and progress update on the upgrade version has been moved to a new page.

	Sudoku Solver and Grader This App contains the full 9x9 Sudoku Solver as seen on this website. This includes the Grading feature and Solution Counter.
	Smartphone to Tablet Four different layouts have been designed to match the many different Android screen sizes and pixel densities from Smartphones (minimum 480x800) to tablets (1280x800).
	Strategy Guides Included are all the strategy documentation found on this site and each example can be loaded into the solver at a click.
	Puzzle Feed The Daily and Weekly puzzles on this site are now automatically downloaded into the App!
	Customisation The solver board can be set to several color schemes including high contrast colors.
	Favourites Keep track of the puzzles you solve with an almost limitless list entry - each nameable.
	Hints New to our solver - Instead of just "Take Step" use "Hint" to give you the strategy to look for without revealing the whole answer.
	Undo/Redo Better than the website with real 'state' saving - quit, resume any time and a start to end 'back' and 'forward' buttons.

Access to the main fatures from the home page

Note: Screen shots have been taken from a 480x800 device and shrunk by half. Other devices may have higher screen resolutions and marginally different layouts.

Feedback and Wish-List
You feedback will be most welcome. If you have an idea for a new feature or improvement, don't be shy. Often these can be implemented very quickly. Bugs and other issues most gratefully received.

I am not 100% certain the different layouts groups I've designed will perfectly match all screen densities and resolutions. If you think the solver page or main page looks a little odd - either clipping or too much padding - please let me know. I can add more layouts. Please include the screen information found at the end of the Preferences screen.

The next upgrade will contain the Sudoku X and Jigsaw Sudoku puzzles - complete step-by-step solvers including grading and solution count. There will be an editor for entering Jigsaw patterns not found on this site or in my puzzles.

I will explore Camera Capture. This is the only major feature present in the iPhone version that's not in this app. Something I'd like to do but it will require a lot of research.

The 'hint' system could use some more work. I prefer the three levels of hints in the iPhone version and I'll be working towards this in later versions. Currently the hint system reveals the strategy used and colors some cells and candidates, but not the eliminations. This can be too much for some strategies and too little for others.

The app has the ability to call and email program with a link to the website solver and the current puzzle. I'd like to do more and add some kind of Facebook connectivity.

Hi.

I just downloaded sudokuwiki solver for android. I think I discover a bug or funcionality (?)

Go to the Strategy docs and pickup whatever section. Navagate through it and then change the device orientation. The document will go back to the beginning of that section.

It's frustrating that the candidates popup appears sometimes hiding the area of influence of the chosen cell.

Would be nice if the application could read a sudoku printed using the camera of the device.

Mi Phone is a samsung galaxy II with android 4.1.2

Thanks for the app !

Thanks for the helpful feedback.

I'm not sure what to do about the docs resetting to the top when re-orientated. It is a web page embedded in a browser object. When reorientation occurs all objects, even app forms and screens, are thrown away and redrawn. There is code in place to restore the contents so its seamless to the user, but it doesn’t extend to the position the user was last on a web page. But I'll do some research, you never know.

> It's frustrating that the candidates popup appears sometimes hiding the area of influence of the chosen cell.

That shouldn't occur and I've tested it on several sized devices - I also have a Samsung galaxy II. Can you go to the preferences screen and tell me what is written at the bottom? It will be something about screen sizes etc. That will help me identify what to look for. Also, if you are up to it, a screen shot of the overlapping popup would be awesome!

I think you can email from the phone picture library.
I am working on the Camera feature, certainly the last major missing item.

I would love to have the solver available for my Nook tablet from Barnes & Noble. As of now the only apps I can have are from them. HELP!!!

I now got the app from Google play. So far it looks good, but there is one minor annoyance:
The app only allows portrait orientation. However I have an Asus transformer, and with keyboard attached, it is automatically in landscape mode and so I can't use the app when I have the keyboard attached.
It would nice to have the possibility to run the app in portrait mode, even without new screen layout. E.g. I could live with the app wasting screen space on a tablet because of the wrong orientation.

Andrew Stuart writes:

I will do that. I hadn't appreciated the device being used in that way, I assumed each orientation was equally optional.
Edit: Now in the current version

Thanks for the feedback!

I'm happy to see the solver published on Google play!
Now I'm eagerly waiting for and looking forward to an update with Camera Capture included. Until then I'm not buying the app as I have no use for an Android solver without capture. As soon as it's included, I'll wait no more to buy it even if it costs substantially more than the current price then. I'm sure it'll be worth it.

Andrew Stuart writes:

I will be researching Camera stuff very soon. I know Oliver had a lot of difficulty with the iPhone version and not everyone is reporting good success with the capture. But we will see.

It isn't worldwide.
I live in 'Trinidad & Tobago' and also cannot order from Amazon App Store.

However I downloaded the solver from Google Play this morning (about 2 am),
and got it. Will look at it later. I know it will be excellent!

Because of geographical reestrictions, I cannot purchase this app. :(

I am looking at why this is. Peter, below, in South Africa also says the same. It should be world-wide apart from Japan. I'll post a message when I know more about it

Any word on the Android version or has it turned into vaporware? Kind of curious because I would really like the app.

Andrew Stuart writes:

I want the Android app too. Now the plan is for me to go on an android developer course.

Frankly, you could have charged more and I would most likely have no problem with buying it. While I don't have the ability to use the program yet (I am an Android person), the list of features alone makes this something that would warrant a higher cost.

Andrew Stuart writes:

Thanks for the endorsement and the comment. I think it’s a very difficult balance between perception of value and the giveaway prices some apps are set up. I was actually a little worried it was too high. You never know how many decide not to buy. Looking forward to the Android version as well

I would like to beta test the Android version. I have several sudoku apps but none of them really do the job.

If u can do a solver for Android like http://www.angusj.com/sudoku/, please inform. The only drawback I find in https://sourceforge.net/projects/sudokuopensourc/ is that it does not allow you to create a sudoku from print like Simple Sudoku.
