When attempting to debug (Run -> Debug), the "waiting for debugger" dialog appears, and subsequently disappears. The simulator starts up to the home screen, I click on my app, and all that happens is a black screen appears. No breakpoints are hit, and the application never appears to do anything. Simply running the application without debugging works as expected. Any ideas?
If you haven't fixed this already - the same thing happened to me. And as Driss says in the comments having a folder called Resources in your project gives the iPhone Simulator a heartattack and crashes it from the looks of things, without even copying your app bundle to the simulator directory.
I think I had a very similar issue. Did this happen with your project "all of a sudden?", did you rename your View's .xib file? did you have a NavigationController then delete it and now have this issue?
Can you also please post your "FinishedLaunching" code from your Main.cs please.
Driss.

I just started learning about Android development, so this one is a serious issue for me: I launch Android Studio (2.2.2, but had the issue since 2.2.1) on Win10, make a New project, just keep clicking Next without changing anything (selecting Empty Activity as the template), Finish, try to Run 'app' on my phone and consistently get this error:
Error while executing: am start -n "com.example.android.myapplication/com.example.android.myapplication.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.android.myapplication/.MainActivity }
Error type 3
Error: Activity class {com.example.android.myapplication/com.example.android.myapplication.MainActivity} does not exist.
Error while Launching activity
Being a complete newbie who was just supposed to change some text in XML and run the app on a phone, I have no idea what to do or edit to make a pregenerated app actually work. I searched StackOverflow for a more general approach to these errors and tried:
Restarting AS/computer
Disabling InstantRun
Messing with Clean/Rebuild/Synchronize/Sync with Gradle
Deleting .gradle and .idea folders and Syncing with Gradle
Some other obscure shenanigans with build.gradle and AndroidManifest
Various combinations of the above.
... None of which worked (or affected the problem in any way, in fact).
Other observations:
The app isn't even installed (checked All apps, there isn't any com.example.android.myapplication or MyApplication app on my device)
On the development course forum, it was suggested that com.example.android.myapplication/com.example.android.myapplication.MainActivity should only read com.example.android.myapplication/MainActivity. So far I haven't been able to figure out how to change that.
Update 1 New attempted fixes (neither of which worked):
Specified activity directy in Run/Debug window.
Specified no activity whatsoever (doesn't show that error, but doesn't run anything either).
Did File/Invalidate Caches
Changed android.intent.category.MAIN to all-lowercase and back.
Added "category android:name="android.intent.category.DEFAULT"/" to Manifest
Update 2 Managed to run the app on emulator. It seems to be working there, so the error will likely be somewhere between AS and the phone (Android 5.1.1, API 22).
Developer options and USB debugging are on (confirmed the pop-up message, too)
Driver is up to date (AS can see the phone without problem)
Phone is on (and not asleep) while I'm trying to run the app
Any suggestions why the phone won't download and run the app?
In your manifest file edit
with android:name="com.example.android.myapplication.MainActivity"
Make sure that your code doesn't mean any nonsense and that it wouldn't cause the app to crash, which is sometimes the problem. Try finding a problem in code which could crash the app. Maybe in your crash log you can find what causes the crash. Good luck fixing that.
According with your error log I suppose you did not delete previously installed app. See my accepted answer on the same question for details.
Writing an android application. It has no errors when I run it on an emulator. But when I tried to build it to an apk file to test on a device, I get the following error.

I seen one similar case raised here which mentions to "Wait till indexing is complete."But I am not sure what I am doing to even interfere with any indexing.
Tried on different computers. Same problem. The only thing I did different before I got this error was to add a dependency at gradle(app) for a RingButton and added that RingButton class to the project to modify it to what I wanted.
As I said it is working fine in emulator.
Just to test if that is indeed the isse, I deleted the class and removed the dependency but the issue is not resolved.
I think this can be solved by creating a new project and moving the files into the new one. Maybe the index is corrupt. But before that can you clear the cache ? in android studio if your prepared to lose some local history then try this:
and then chose invalidate and restart:
I was using Dropbox to constantly backup my project every now and then. So I would click my project and send to Dropbox. I was also instantly clicking run to run the app on my emulator at the same time. During this period, when I mouse over my Dropbox icon, there is an indication that it is "Indexing".
Based on previous answer "Wait till indexing is complete", I can only assume this Dropbox indexing interfered somehow.
Not exactly elegant but I copied each and every file in this project into a New Project and everything is working fine now and able to install the apk file. I didn't change anything so I believe there is some form of corruption in the old project.
We use CFrameWnd in extension DLL for some application, the MFCMenuBar::CreateFromMenu(...) is used to add menu bar. Everything works well.
But if some manipulations with the menu were performed and then main app exited it crashes somewhere in ntdll. Happens only in Debug build.
If menu is not not touched, the app does not have any issues. Any clue what can it be? Some conflict of menus with main app frame?
I have not found a good simple tutorial for this. I just want the app to freeze at the breakpoints so I can explore the contents of the various variables, particularly their json content.
This is a garbage documentation:
http://www.jetbrains.com/webstorm/webhelp/running-and-debugging-node-js.html#d40161e701
I can't even set up breakpoints. Is it so simple to do this in Eclipse...
UPDATE
Using Webstorm 7.0's early access build, the debugger works flawlessly. I just made a new project, added a breakpoint and used Debug. Stopped at that breakpoint with no problems whatsoever, so apparently Webstorm 6.0's debugger sucks :D
You can get it here: http://confluence.jetbrains.com/display/WI/WebStorm+7+EAP Beware, it expires on 8 August.
I use webstorm and it's great. Having looked at that documentation, I agree. If you're just starting out, you don't need all the remote and attach to existing processes options.
The easiest option would be to rightclick on your main js file and choose debug. Setting breakpoints is the same as in most editors these days, just click left of the line.
If you don't get the debug option when you right click then you need to make a run/debug configuration which sounds worse than it is.
Select "Run" -> "Edit configurations".
Click the plus sign.
Choose "Node.js"
Click on the browse ... button on the Path to Node App js file and choose the file you want to debug
Click Ok.

I have an MVC3 app that's been working for quite a while and today began crashing anytime I launch a debugging session with IE as the initial browser. If my initial browser is Chrome or FF - no problem. Further....if I open the site with IE _after it's been launched to one of these other browsers, no problem. The debugger's break points respond just as expected. So that's pretty strange, yes?
I can F10 without hitting any problems until the point where the browser is invoked and, up to this point, haven't been able to catch the last couple lines in VS's output windows - it crashes and restarts without giving opportunity to copy any of that output.
Event viewer shows:
Fault bucket 3561940412, type 5
Event Name: CLR20r3
Exception code: 0xe0434352
(there's more erreta if you'd like deeper details) - searching against those codes looks like it's a fairly general/generic error.
I've stepped out to the file system and deleted the .obj and .bin folders for all the projects in the solution, rebooted a couple times, and am in the process of getting on with my life cuz, as of right now, this is easy enough to work around.
I suppose i could delete windows temp files and check again. Any other thoughts?
