Publishing Windows Phone 8 apps with sqlite database - sqlite

Considering that an app using a sqlite db, needs to be build for x86 platforms in order to run on the emulator and under ARM in order to get deployed on a device.
The question is, how does one publish a WP8 app with a sqlite database? Under which active solution platform in the configuration manager menu should the project be build in order to pass the store verification?

When publishing to the store you publish the ARM version, because that is the only version that can work on an actual device.
Just set the Build Configuration to target ARM and set it to Release. Then look in the Bin/ARM/Release folder for the .xap package.

how to publish app to apple store using windows

hi I have been created an app at Xamarin form and I want to publish them to the apps store
on the google play store that was very easy
the problem of how to publish the app on apple store if I have just windows
I know that I have to use Xcode and just on mac
I think there is some way to do that from windows
Well in fact you could do it without a Mac, installing a Virtual machine as shown in this video, after that, you should be able to download the last version of Xcode through the App store within the Virtual machine. Then, within Visual Studio in your Windows, connect with your just created Catalina VM.
After that, you colud use Testflight instead of publishing the app directly on the App store in order to build beta tests.

Build Problems with SQLite-WinRT Wrapper

I am having trouble getting my app to build for ARM target after adding the SQLite-WinRT database wrapper. I could reproduce this with a simple test app as follows:
(This is done in Visual Studio 2013.)
Create an empty Windows 8.1 universal app (WinRT)
Download SQLite for Windows Phone 8.1 and SQLite for Windows Runtime (Windows 8.1) using Tools/Extensions and Updates. Add them to the respective projects' references.
Using NuGet, add SQLite-WinRT package to each project.
Build for x86 (local machine or phone emulator) -> no problems.
Build for ARM (phone device) -> build error shown below (independent of debug or release builds).
There was a mismatch between the processor architecture of the project being built "ARM" and the processor architecture, "x86", of the implementation file "C:\Users\jr\Documents\Visual Studio 2015\Projects\sqlite-test\packages\Sqlite-Winrt.3.8.7.1\lib\wpa81\SQLiteWinRT.dll" for "C:\Users\jr\Documents\Visual Studio 2015\Projects\sqlite-test\packages\Sqlite-Winrt.3.8.7.1\lib\wpa81\SQLiteWinRT.winmd". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and implementation file, or choose a winmd file with an implementation file that has a processor architecture which matches the targeted processor architecture of your project.
I posted a small test project here (Windows Phone 8.1 empty project, added SQLite, added SQLite-WinRT via NuGet).
Go to project properties open build tab and set target platform to ARM
Edit
You have added WinRt sqlite. it is buid on x86 and when you want to build it on ARM process Architecture it cannot build you need to remove WinRTSQlite dll than your project will work fine. Here is Code
Hope this helps
One workaround for the problems with the NuGet package is adding the sqlite-winrt sources to your phone or universal app.
install SQLite for Windows Phone 8.1 (and for universal also Windows Runtime (Windows 8.1)) in Tools -> Extensions and Updates if not done already
add references to the respective projects
download the sources for the sqlite-winrt wrapper
copy the SQLiteWinRTPhone81(RT) (and SQLiteWinRT81 if needed) folders to your solution
add the projects to your solution in Visual Studio (right-click on solution -> Add -> Existing Project)
add references to the respective projects
edit the references for the sqlite-winrt project(s) to point to the correct version of SQLite (right-click project -> Properties -> Common Porperties -> References): add a reference to the current SQLite version in your project and remove the old reference
build your solution
I have downloaded your project and on the references i have found that you are using SQLite-WinRT and sqlite for windows phone 8.1, you don't need both.
as soon as you remove SQLite-WinRT your project start compiling.
EDIT:
inside a universal app you have to add only the right references, if is a phone project just add sqlite for windows phone 8.1, instead on the windows 8.1 app add only the SQLite-WinRT

FileNotFoundException in xamarin.forms in sqlite implementation

In my project where i am using sqlite i get this error.
An exception of type System.IO.FileNotFoundException occurred in SQLite.Net.Platform.WindowsPhone8.DLL but was not handled in user code
Here is a screenshot.
P.S. i got value in variable path as C:\Data\Users\DefApps\AppData{F8267584-1051-4816-8195-EE018BA5155E}\local\Student.db3
Thanks
You're missing Sqlite for Windows Phone. iOS and Android have Sqlite "build in", meaning it is available directly on the platform. Windows Phone ships without Sqlite.
To add it, first prepare your development machine by using Tools -> Extensions and Updates in Visual Studio. Search online for "sqlite windows phone". You must install the one for WP8 (not 8.1). When done, your machine is ready to deploy Sqlite with a WP project.
Next, add a reference to Sqlite to your WP app. Right click References in your WP project. Select Add references and in the menu select Windows Phone SDK -> Extensions and select Sqlite for Windows Phone.

cant use store test kit while Working with SQLite in Windows Phone 8

I am using SQLite.WP80 version=3.7.16 in Windows phone 8 project.
Now when I tried to test with store test kit it says:
"the application package(XAP) is not up to date,recompile and try again.
change the solution configuration to release and platform to any cpu and rebuild the app"
But as I am using sqllite i cannot change to any cpu.
Can anyone tell possible solution?
You should target just one CPU during development (depending on what machine you will be testing/debugging on). When it's time to publish your app, you can select multiple packages, one for each CPU architecture. Visual Studio will then create several packages, which you can upload to the dev portal.

Is sqlite db file available under any platform?

For example, can I generate a SQLite db file and put it as a resource in the project. When the project first launches, copy the db into isolated storage without worrying this db file may be unavailable in the phone. Furthermore, can I copy this empty db file into another platform, like android or iPhone, and operate this db by in SQLite api of the platform.
From the SQLite web site:
A database in SQLite is a single disk file. Furthermore, the file format is cross-platform. A database that is created on one machine can be copied and used on a different machine with a different architecture. SQLite databases are portable across 32-bit and 64-bit machines and between big-endian and little-endian architectures.
So yes, when you've validated that the SQLite API is available everywhere you want to use it, that should be fine as a storage format.
EDIT: And yes, SQLite does work on Windows Phone 7, using this Codeplex project or this one.
Yes. We are using the same SQLite database in an iOS, Android and WP7 app. I've written a quick start guide here: http://wirebear.com/blog/2010/11/12/using-sqlite-in-your-wp7-app
The above blog post covers copying your database from your resources to isolated storage and correctly configuring SQLite to work on your device.
The SQLite version is compatible with Android - iOS - WindowsPhone as far I have experimented. I have created SQLite DB on a Mac Desktop and copied it into projects along with data into each of these platforms. Everything worked fine no issues.
Ref:
http://www.sqlite.org/download.html
Precompiled Binaries for Windows Phone 8
sqlite-wp80-winrt-3071502.vsix (2.72 MiB)
A complete VSIX package with an extension SDK and all other components

The download page itself lists the entire code and binaries for different platforms. Using a PC/Mac for creating a DB is convenient option.
You can use SQLite manager for doing so on a Windows or Linux PC.
SQLite Manager (Preferred by Myself)

There are also extensions for Chrome and Firefox, which makes SQLite Available for almost any platform to Manage them.
Firefox Plugin for managing those files.
https://code.google.com/p/sqlite-manager/
codev.it also allows to enable editing SQLite Files.
As far as DB is concerned, Exporting them from the device is as described by #Jon Skeet
SQLite 3.7 is more compatible with Windows Phone. Since SQLite DBs are backward compatible, there isn't any need to worry weather your DB works on older 2.x version or 3.x..
Hope this helps.
#Bhuro As you want a detailed procedure for using SQLite db in a Windows Phone 7 app, Here is a good post Native Database Programming via Sqlite Client for Windows Phone.
I have successfully followed the same process in my WP app. Try that and let me know if you get any doubt.
Good luck !!
