I have an Objective-C app I wrote roughly 12 months ago, with the iOS Deployment target set to 12.1 . I added the ResearchKit framework to it, and during the time of development the app was working fine. What I do remember is that it only worked on an actual device and not on the simulator.
A year later Im back to make changes, using Xcode 11, and am now getting a familiar error, solution to which I cannot figure out. This is both on real device and simulator.
I have done all that is required to add the library. See attached images below:
TARGETS -> General Tab
TARGETS -> Build Phases
ERROR
Attempting to run on an iOS 12 device fails too. Is there something I'm missing?
I ended up removing the pre-build Research.framework and adding the full Project instead:
Remove the Pre-built ResearchKit.framework file, select Move to Trash when prompted.
Make sure the ResearchKit project is closed (if it's open it wont be added as a project but as a file)
Drag and drop the ResearchKit.xcodeproj project file, into destination project. After this make sure the ResearchKit project has its files under it.
Go to Main project file of your project (not ResearchKit) and select your Target.
Make sure ResearchKit.framework is listed under Embed Frameworks. If not, then add it by selecting the + button and selecting it from the list. If it is not on that list then build the ResearchKit project to create the .framework file.
Under the same Target, go to Build Phases, and make sure ResearchKit.Framework is added under Link Binary with Libraries, and also under Embed Frameworks. If not then add it where absent.
Build and run.
There may be better ways to resolve the issue, but for now this works for me to run the App. App now runs on simulator. However, an initial build takes up-to a minute because the ResearchKit project it pretty big.
Update: I later figured out that the reason why I was encountering the 'Image not found' error is that I was trying to run on simulator while the ResearchKit framework had been build to target arm64 (real device). You will have the same issue the other way around (attempting to run on device-arm64 while app was build for simulator).
So how do the above steps fix this? That fixes the issue because by having the ResearchKit project files included you get to build everything for the currently selected architecture, whether device, or simulator. Happy coding.
When debugging, building, and deploying in debug mode to my Nexus 9, I sometimes see sigsegv 11 and/or my breakpoints not getting hit. I think this is due to my debug code not always getting updated on the actual device. Why, I don't know. I have tried all the following:
turn OFF "use Shared Runtime"
delete all bin and obj directories
full clean of the entire solution
After doing a complete fetch of my entire project in a clean directory to make sure I was starting fresh, I saw that my old log statements were STILL appearing in my output. I finally found the obsolete versions of the DLL files that should have been replaced by VS2015 on the device using ADB shell running on the Nexus:
flounder:/storage/emulated/0/Android/data/com.myproject.debug/files/.__override__
I executed in the ADB shell a rm:
flounder:/storage/emulated/0/Android/data/com.myproject.debug/files/.__override__ $ rm *.*
in the above directory on the Nexus and my debugging starting working after that. I hope this is the end of all my issues but I'm not sure how my code ended up there anyway and why my deploy was failing to get it updated. I now make sure to change my log statements every time I deploy just to make sure that it is actually running the new code. It's been deploying and working well since I deleted those files on the device.
So, I guess my question is, how did my debug DLL files end up in that directory (they haven't come back) and how can I avoid ending up in this situation again?
Thank you.
In addition, please change another device to check whether this issue caused by this device only. If only this device has this issue, I'm afraid this issue related to the device itself, please reboot your device and check whether there has any settings will lead to app file caches.
If other devices also has this issue, I suggest you uninstall the app from your device before you re-deploy it to device, which could make sure the old dlls are removed from your device.
I'm at the point where I'm ready to build, but when I try to archive the project I get the following error in xcode:
app_sign cannot resign
/Users/me/Library/Developer/Xcode/DerivedData/My-App-bzgdaitstcabzpaiygqfnluetfhk/Build/Intermediates/ArchiveIntermediates/App/InstallationBuildProductsLocation/Applications/My-App.app/My
App. Please remove and then build
Does anyone know why this is happening?
In build settings I've tried leaving the code signing identity blank, and tried it with the correct distribution profile.
I've tried with and without the provisioning profile specified.
I've tried deleting the whole file in my DerivedData folder.
It would seem that this is the line in question that causes the problem:
"$TOOL_PATH" app_sign sign "$SHARED_RESOURCE_DIR/developerkey.cert"
"$CORONA_RESOURCE_CAR_PATH/resource.car" "$CORONA_EXECUTABLE_PATH"
little
But I don't know enough about what it's doing here to think of the solution. If I build the sample app that comes with Corona Enterprise still builds fine, but my own app still fails.
It turned out that the problem was to do with the xcode.proj file itself. Not sure what the cause was, it seemed to be keeping a reference to a file which no longer existed, rather than the new build.
I made a new project, copied all of my own source files across but left the new proj files in, and then it built successfully.
I installed a retail version of Windows 8 Pro. I downloaded and installed Visual Studio Express 2012. I asked for and received a developers certificate. Then I tried to create a hello world app.
From there I get a "Unable to Activate Windows Store App" message box when I try to debug the app. Most commentary on the web says delete build directories. This didn't work for me
Does anyone have a solution for how to fix this and debug my app?
This happened to me once too, but the deleting build directories advice fixed it. Specifically, you just need to delete the bin\Debug and bld\Debug folders in your projects. Their contents will be regenerated by Visual Studio when you rebuild. I assume that this is only one project since it's a Hello World app; otherwise I would ask if you deleted build directories from all projects in your solution.
You can also try running "Clean Solution" from the BUILD menu in Visual Studio.
I'm sorry...it's horrible if this is happening on a clean install as you describe.
I ran into the same issue, and tried rebuilding, cleaning, deleting temp files, rebooting the computer, etc... and nothing helped.
Then finally I made a release build then went back to debug. And now it works.
I have no idea what happened, nor if that really helped, but it's worth a try.
For me a RESTART of pc solved this error message.
For me the problem was that I created the app on a TrueCrypt mounted virtual drive and when I moved the project files to a normal drive then everything worked just fine. Weird.
I was getting the exact same error. In my case the culprit was a NuGet package. It had added an app.config file to the project and it was confusing VS. I removed the app.config file and it solved my issue.
I got the solution at Iris Classon's site.
This can be solved by Uninstalling the app from the start screen then again building the app from Visual Studio.
I had a similar problem, and the cause was creating the project on a USB thumb drive. Creating a project on a normal hard drive volume works.
this can happen when the application signing key (.pfx file) is missing.
Try the following:
Open the Package.appxmanifest file in Visual Studio
Go to the register "Packaging"
Select [Choose Certificate…]
Select the test certificate using [Configure Certificate…] [From File…], or create a new one using [Configure Certificate…] [Test Certificate…]
When using a test certificate, ensure that it is in the .gitignore file. There should be an entry like !**\*_TemporaryKey.pfx to include the key in Git.
Note: The certificate for release build should only be available to the build server and not included in Git.
Rebuild the project
This has happened to me in the past and I have always found that deleting the build directories resolves it.
However this time this is not working for me.
I have tried
- Rebooting
- Deleting build directories
- Running Build | Clean Solution in VS
- Renewing Developer Account
The only thing that will work for me is changing my Package name under the Package.appxmanifest
However I am not overly happy with this as a solution. I will keep investigating.
The issue might be caused because NuGet will try to add an app.config with binding redirects to Windows Store apps if it thinks it is needed. However, Windows Store apps don’t need app.config, and will actually fail to start with a very confusing error message if it is present.
And the solution in this case would be to Remove the App.config
This error generally comes when you try to deploy in debug mode.
I would suggest, deploy the app first in release mode and then try in debug mode.
This worked for me.
Making a new certificate works for me. For this, go to Package.manifest->Packaging, and follow the Choose certificate.... Click on Configure certificate and select Create test certificate. Give it a name and press OK.
Increasing the revision number of the package worked for me
Tried so many of the above fixes. Nothing worked (deleting bin, obj dirs, editing the manifest, editing the registry, changing package name, etc, etc.) My Avast antivirus software was running and so I uninstalled it completely. That was it. App now runs fine.
This sort of problems are common with Windows 8 Visual Studio. Such errors encounters when your developer license of Visual Studio has expired so you may want to renew or get a new developer license here's how you get that. How to get a developer license in Windows 8
And similar problem may also encounter with E_Fail issues here's how to solve Unable to activate Windows Store app E_Fail Issue
For me, the fix was a combination of two of these answers -
Renew the developer license (How to get a developer license in Windows 8)
And deleting the build directories (though I deleted more then the screenshot depicted) Delete the Build directories
NuGet will try to add an app.config with binding redirects to Windows Store apps if it thinks it is needed. However, Windows Store apps don’t need app.config, and will actually fail to start with a very confusing error message if it is present.
Solution:
Remove the App.config
and build again
For those who get a similar error but who are searching for a solution while debugging an IOT background app on a local machine specifically - you can find it here.
Using the search term "unable to activate windows store app the activation request failed with error" brought me here.
Because of Two things i resolved this issue.
Basically, we just need to delete the bin\Debug and bld\Debug folders in our projects. Those contents will be regenerated by Visual Studio when you rebuild project.
Just Restart the Visual Studio. And Clean Build and Rebuild the solution and RUN it.
Hope this helps.,
Playing with this issue for 3 days, tried every suggestions, nothing works. Until now!!!
The solution was this for me:
renew developer licence
build and deploy solution in Release mode (after this step it still not worked, but VS installed some packages in rpi)
start VS remote debugger with default account (http://:8080/#Debug%20settings)
configure remote device with Universal authentication mode (VS2017 -> Project settings -> debug -> target device: remote machine, authentication mode: Universal (unencrypted protocol))
...and now I can sleep.
Hope it helps somebody.
This gift was courtesy of Microsoft's automatic updates for VS2015 which was one of the 2 culprits:
KB3022398
KB3165756
It also broke SourceTree and other apps that draw the GUI - making an outline of the app but not drawing the contents.
For me changing the Package Name in Package.appxmanifest fixed the problem
In my case, the C# UWP app had a native library which failed in the application startup code, and called exit(1). The symptoms were identical to those in the question, though. Visual Studio would throw a message:
Unable to activate Windows Store app '88888888-6666-5555-4444-111111111111_abcdefgh!App'. The Acme.exe process started, but the activation request failed with error 'Operation not supported. Unknown error: 0x80040905'.
In addition, there was a message in the UWP app Windows log under Microsoft\Windows\Apps\Microsoft-Windows-TWinUI/Operational: event ID 5961, message:
Activation for 88888888-6666-5555-4444-111111111111_abcdefgh!App failed. Error code: Unknown HResult Error code: 0x80040905. Activation phase: COM App activation
Internally, the C# part would try to construct a native class instance from the App constructor, the native class constructor would encounter an unrecoverable error and bail. From the UWP subsystem standpoint, and from the debugger standpoint, though, this looked as something distinct from the mere programmatic exit. I'll leave this answer here, 'cause I've spent some time chasing various UWP failure scenarios instead of running under a native debugger.
I've replaced the exit() call with throw ref new Exception(E_INVALIDARG). At least this way the error manifests in the managed debugger, and the message is descriptive.
I've been having this problem a lot with a UWP Windows 10 app on Visual Studio 2019...for me the reliable workaround is to bump the Build number in the Package.appxmanifest file (Packaging tab). It's a huge pain...really hope Microsoft will sort this out soon
Any existing error in the code can also cause this issue. Make sure your previous version of the code is working fine. Compare the difference and make sure all looks good.
I was getting this error and nothing else worked so I had to dissect my program. Turns out I referenced a StaticResource in my App.xaml that didn't exist.
Seems like a silly error but you'd also think Visual Studio would pick up on something like that and throw a different error so if nothing else works, double check your application resources.
As suggested by #Iman in a comment, in the UWP project settings, enable "Compile with .NET Native tool chain".
