WP8 app crashes after downloaded from store - windows-phone-8

Recently I created an app that uses background agent and live tiles in it. The problem is - the application works perfectly when I straight away deploy the XAP file to device(or emulator) but when I download the same app from store, then the app exits without even navigating to MainPage.
Is this because of background agent or anything else, I don't know am totally confused in this. Can anybody please help with this?

If you're application uses a periodic Background Agent and you are testing it with the LaunchForTest method you should make sure that you are not calling this in your release build of the code.
Protect it with appropriate conditional compile time checks:
#if DEBUG
ScheduledActionService.LaunchForTest(periodicTaskName, TimeSpan.FromSeconds(1));
#endif
Note that DEBUG is defined by default in the "Debug" configuration and not in the "Release" one for situations such as this.

AIR Build Server Setup

I am at the point where I am running into incredibly long build times for my project and more projects to come. I would like to make a build server but I have not had any experience with them aside from downloading files from them as an end user.
My ideal setup is this: A GitHub where I can place my .fla file, classes and ANEs. The server sees this, compiles it, and allows me to test it remotely or hook into some debugger that lets me see stack traces and active variables at breakpoints and errors like Adobe Animate or Flash Builder.
Now I see there are GitHub plugins for Jenkins. I see there are questions referring to how to set one up with Flex/AIR. I come here with a few issues.
I am too far into my project to switch over from using Animate to something like Flash Develop or anything ADT related. The only thing I have found is how to take existing elements from my library in Animate and have them in a .swc for handling. However, this doesn't let me access existing elements in the Timeline and would rather not try to export/position/handle them in code (which is the only workaround that I see if this is not possible)
I run ANEs that are dependent on Google Play services and other Android specific libraries. Thus, I haven't been able to use the standard mobile debug launcher for AIR. I see Jenkins has some specific abilities for Android. Is it possible to somehow use this to give me a proper window for testing? I am thinking that I would need to run their emulator after compiling everything but I am unsure if there is a more efficient method or if it would even work.
I have never worked with Jenkins before or any other tools capable of automating tasks. Any step by step explanations is appreciated if you have the time.

Changes To xaml don't reflect on App Until rebuild - windows phone

I have a weird problem in an windows phone 8 project (Visual Studio Express for windows phone 8) that Changes to xaml( ex:change visibility of control) don't reflect on App until I rebuild the project and deploy it again to emulator or device.
The changes reflect normally in the design window of visual studio but didn't reflect on the running App.
I did many researches and they didn't help, like:
1- Change "Build and Run" to "always build" when projects are out of date.
2- I checked configuration manager as This post suggests but it was selected.
I have the exact same issue. I have a work around at the moment to save the hassle of rebuilding the solution because rebuilding deletes and re-installs the app and changes any saved settings you've made while debugging. The work around is to switch between configurations. So I'll execute the app in Debug, make some changes, then the next time I execute I change config to Release, and the changes are there.
The difference I can see is when it works I can see the Build Output line which says "Updating the application as the manifest file has changed..." take a few moments to complete. When this issue occurs the output line appears for a split second and so you can tell the incremental deployment hasn't actually been deployed to the device/emulator.
This is a little frustrating so hopefully someone has a real answer. I have other projects on the same machine and they don't have this issue. Just the one project so I don't think its a VS2012 problem.
I've also tried suggestions from other sites saying delete bin and obj folders but that didn't work.
I had the same issue for some of my WP8 Silverlight projects in VS 2013. I couldn't understand why it happened only for some projects but not all, but eventually I found this forum thread. The solution is the following: if the name of your app includes spaces, you definitely need to remove them or replace say with the underscore char. This recipe helped to recover my 'problem' projects.
I also noticed that numbers at the beginning of app name cause the same problem. I solved it by removing numbers from solution and app name.

Using Bluetooth ANE for Android

I'm relatively new to flash, air and AS3 so I'm sorry if this comes of as a beginners question. I have made an application in AIR to run on windows and communicate with my atmega8 chip through serial communication via serproxy.
Now I want to port that application to android to perform the same basic functions but communicate to the atmega8 via bluetooth. So I created a new Air for android file in Flash CS6 copied my code from my previous application excluding the communication through sockets part and created an apk which ran on an android phone:). It did everything except the communication as expected.
Now I have been trying to implement the as3breeze.com/bluetooth-ane and use it to communicate but I'm not too sure how to go about the whole thing. I have imported the ane through actionscript settings and have implemented the classes but when I try to test I get this error.
The content cannot be loaded because there was a problem loading an extension: Error: Extension namespace is invalid for C:\Users\AppData\Local\Temp\Tmp_ANE_File_Unzipped_Packages\AndroidBluetooth.ane
So after some searching I found posts talking about as3 sdk and flash builder. Do I really need all these things or can I make my bluetooth app work some how with just flash cs6? Also what exactly does my error mean and how can I solve it. Thanks in advance for any help. I have been searching so a solution to this for days and I either get an explanation that does not work or I lack the knowledge to understand.
The path that can't be accessed makes me believe you haven't extracted the ANE (basically you're trying to access a temporary directory). Try extracting the ANE file to somewhere, like My Documents or wherever your flash project is, and include (in the actionscript settings) that path instead.
Hope it helps.

How can I determine if I am running a side-loaded app or a Store-installed app?

For the sake of testing, knowing that I am running from Visual Studio would be nice. I could see if the debugger is attached, but that is not sufficient if I am running with CTRL+F5.
Here's how to see if the debugger is attached:
if (Debugger.IsAttached) Foo();
But my question is, I wonder if there is a way to ask if the current app is from the Store. So, I thought about install folder, but they are identical. Then I thought about this:
Windows.ApplicationModel.Package.Current.Id;
But this appears to be completely implemented even for apps that are being debugged. So, I am stumped. Does anyone know if we can determine if the app is from the Store?
While certainly not the most elegant solution and there's probably a better one, you can check Package.Current.InstalledLocation.Path
If you are running a debug build developed on your local machine and not side loaded, you'll have /debug/ in your folder path.
In Windows 10 apps (this also should be available in 8.1), you can check the IsDevelopmentMode property on the current package.
Package.Current.IsDevelopmentMode
That should tell you whether the package was installed in development mode (which I believe is synonymous with 'side-loaded').
See https://msdn.microsoft.com/en-us/library/windows/apps/windows.applicationmodel.package.isdevelopmentmode.aspx

Flash Builder 4 changes not compiled

Im using Flash Builder 4 on the Mac and I have a worrisome problem: The compiler is sometimes not detecting my code changes.
For example I might write some code, compile and run, then add some logging statements, but they will not print. After a clean compile everything runs as expected.
I cannot see a pattern to the exclusion of changes. I'm wondering if anyone else is having the same problem?
Details:
Flash Bulider 4
Pure AS3 project targetting Flex3.5 SDK
Max OS X Snow Leopard
My code does not use semicolons to terminate statements
The problem is with the SDK settings selected for the Compiler.
Try going to 'Project' > 'Properties' > 'ActionScript Compiler'.
Now, in the 'Flex SDK section', try changing the SDK. Click on 'Apply'.
This will force FB to rebuild all settings for the project.
You can try again. FB should now have started compiling with latest code changes again.
Please Note: This is not a permanent fix though!
In case the problem re-occurs, you'll need to again perform the steps mentioned above to get FB back on track.
As bad as it sounds, I am now used to this behavior, I use FB4 on a Mac , but remember having the same issue with Flex.
Practically, I keep clearing the browser cache and cleaning the project. I have thought about adding some random number after the swf url so that it never gets cached but haven't implemented it yet. Force of habit I guess, clearing the cache & cleaning the project has become such a routine!
