After being kicked off of reddit and told to come here, I have some massive questions.
I just started to code, I am trying to release my first app. However, right as I went to submit it, I messed up and everything is crazy now! So I will start at the beginning:
I am making an app that lets you shuffle between ideas on what to build in minecraft. Each tap brings up a new random idea - that is all. It is super simple, I am keeping it that way since it is my first ever app. Now, I had it working, I have every drawing I need for the app. But as I went to submit the app to actually publish it, my .apk file was invalid. I was using the test version, which wasn't allowed to be used in the submission.
I then followed a guide that instructed me to delete my Gradle and .Gradle folders, and apparently android studio was supposed to regenerate them and fix it. Well, that did not happen. What happened was that my 'Android' folder in Android Studio became empty - there is now an app folder with nothing in it, and a Gradle Scripts section with various files that I had not seen before. The majority of my file names are red or orange.
Now, most of if not all of my code is still here. However, it says that the Gradle project sync failed, and I don't know what that means. I can no longer find out the source of these files, as in, there is no manifests or java folder located within my 'Android' heading. I don't know what to do to get it back. I had almost everything taken care of, and I am certain there is a simple way to get it all back. I did not make a VCS at the time, since nobody ever told me I should. Like I said, I am new at making apps. I still have the folder with what appears to be every single bit of code I have made so far.
If you can help me I will be extremely grateful. I have spent almost three weeks working on this, and it would be horrible to see it all go down the drain over one simple mistake.
What about creating a new project and adding your source files, dependencies and resources to it?

Here is the error I'm getting when trying to archive my app for deployment.
This error doesn't show up at any other time. The project builds and runs on emulators and devices without issue. This error has zero context or direction as to where to look to fix it. It also just randomly showed up out of nowhere, last time I built/archived (with zero functional changes) this error did not happen.
Main difference between this archival and the previous one is a newer version of VS 2017. Don't remember exactly the version from before, but am currently on 15.9.4 (stable).
Looking around on the interwebs, I've found that this error seems to have something to do with ObservableCollection's, which there are probably 10-ish in my app. Not really sure what to do here, because this has never been an issue previously, and I'm coming up on a deadline and with the structure of the app, am not in a good position to start making functional changes.
EDIT
I have also cleaned and rebuilt my solution, as well as deleting all bin/obj folders in my xamarin projects. Even tried deleting the .vs folder which can sometimes help. But still no go.
Going to try updating VS to 15.9.5 and see if maybe it was fixed in a release.
EDIT 2
Updating VS 2017 to 15.9.5 made no difference.
EDIT 3
I had my coworker try archiving the exact same project on his machine (running VS 2017: 5.9.3, and it archived fine for him. So far that's the only difference we've been able to find between our environments.
I saw the same problem using VS2017 15.9.9. Even the same code that could be archived a week ago threw the above mentioned error. It seems related to local data in the solution. A "clear" build was not sufficient. However manual deletion of the local obj and bin folders followed by archiving (build is done implicitly) solved the problem for me.
For my part closing Visual studio and deleting the .vs hidden folder did it.
It's actually a fix for many issues using Xamarin.
I had this other issue where I couldn't archive because the build process would just hang and never end. Deleting the .vs folder did it too.

Just go to project property then go to Android options-> Select Advanced then increase the Java Max heap size to 2G/3G -> it's working for me.
Leon Lu's suggestion worked. I don't particularly like it, as it took forever and repairing basically restores you to a base install (no extensions or personalizations). Took about 1.2 hours to complete, but once done I was able to again archive my android application. I guess something went wrong in vs at some point, perhaps during an update. There's no way to tell.
I tried ALL of the ideas above, but had no consistent reliable luck with any of them.
I found that Microsoft has had the problem reported to them (see link below). After a ton of time burn on this, I posted at the link below one way that I've been able to get around this archive-build issue.
Like the other fixes, it's not exactly logical, and nothing that you would think would work, but I've found the process to be repeatable, which is golden for me with tight timelines and having no time for this.
MS Visual Studio Developer Community Problem 507708
Posted on a Saturday morning, a sign of really needing to get around this urgently. I hope it helps you too.
i recently started the android tutorial from android.com, after downloading and installing Android Studio and the sdk. I made the first app and all, working directory is on a Flashdrive, Android Studio and sdk are on the HDD.
I'm currently stuck at the "Adding action bar buttons" tutorial, as android studio doesnt find "#drawable/ic_action_search".
I understand that it should be in the MyfirstApp/app/src/res/drawable- folders, but those are practically empty (see picture below).
I did find an answer on here that states to simply copy the required drawables from sdk/platforms/android-/data/res/drawables-.
Another one states, I can adress "standard" pictures (like the search action icon in my case) by using "#android:drawable/ic_action_search", but that doesnt work at all.
Is there a good workaround, easier then putting every icon in every corresponding folder, every time i need one? The tutorial doesnt have that, it seems the guy writing the tutorial relied on the icons just being there?
(May solve itself with 1.)
In that other folder, there are many, many drawables, but the one folder I searched (drawable-hdpi) doesnt even have an icon called ic_action_search.png so...where do I usually get that?
Thanks for helping, I'm still hoping this is a common mistake so there's an easy solution here^^
Edit: manually starting the gradle build task doesn't work either, same problem.

Does your project build? Try running the gradle build task manually.

OK, I have been wanting to try the new ActionBarCompat, however, I am not able to run my programs in the emulator.
I have been trying to implement the following: http://antonioleiva.com/actionbarcompat-how-to-use.
and have been stuck on basically the first part. However, working with the author of that content, I was able to get further as I was not adding the project under sdk\extras\android\support\v7\appcompat folder like stated. However, I still think that might be the reason I cannot do this...
More detail can be found here: http://antonioleiva.com/actionbarcompat-how-to-use/#comment-43
Basically, on my first attempt, I just created an Android project, and changed the source code as indicated. Code would not run on the emulator. So I went back to the original code, and that ran on the emulator.
Checked online, found out I might need to add the \extras\android\support\v7\appcompat folder as a library to the project I am building. So I added that and a new android project was created. There were build errors from the start, but I failed at trying to add it as a library to my project, and deleted it....thinking this was way overboard.
After back and forth chats with author of linked website, I found out I had to do that overboard thing.
So I tried the following link to the T: (I cannot post more than 2 links due to low repuation...I will add this link as a comment below)
However, Eclipse would not allow me to add the appcompat Existing Android Project...but it did allow me to add the appcompat Existing (General) Project. I think this may be some of the problems??
Right now, I cannot run the project at all. Eclipse is showing a red exclamation mark on the project folder, but all the code seems to be fine. So I don't know what to do now...I recreated this project several times over, and this one was the one where I knew what to do...and I am still getting problems
So...
I decided to move to Android Studio...updated the IDE, updated the SDK manager to include the new support library, and other things. Created a new project, added to the build.gradle file as shown in the link provided below in the comment. I ran the ant build, and then built the project...tried to import the right things to allow ActionBarActivity, but I could not get that far.
I can import
"android.support.v7.*"
"android.support.vy.R" // and all folders within
but nothing allows me to add ActionBarActivity, and I don't know why.
FYI, I guess I would prefer a solution to Ecplise, as it seems like I actually got somewhere with it.
The best example to use is from here, and I would follow it closely. I had similiar issues when I first came across this. Problem was I misunderstood what I needed to do
http://developer.android.com/tools/support-library/setup.html#libs-with-res
UPDATE 2
I posted an answer that fixes my original problem. See that for more information.
UPDATE
FYI for anyone wondering, in the end I found this: http://github.com/commonsguy/zxingdemo/tree/master Exactly what I needed to get it rolling was a simple demo that worked! Also, thanks to Sean for pointing me in the right direction for my googling.
I am currently trying to build a simple android app that can scan in a barcode. I have looked through multiple tutorials, tried everything to a T, and re-tried and re-tried. Nothing worked. So now I am going to ask for assistance to see where I went wrong.
To list the tutorials I have followed:
https://github.com/phonegap/phonegap-plugins/tree/master/Android/BarcodeScanner
Tried this one first.
http://www.mobiledevelopersolutions.com/home/start/twominutetutorials/tmt3
http://simonmacdonald.blogspot.com/2011/12/installing-barcode-plugin-for-phonegap.html
Plus a couple others, but more or less hit the point to the same process. Some key points, when I add the LibraryProject to my project as a Library, the app will not compile until I create an AndroidManifest.xml I tried using the one found in the LibraryProject and tried creating a bare mininmal one, both would allow to compile, but the app ForceCloses.
When I load up the App and click "Scan" it ForceCloses and in the debug log of LogCat in Eclipse I get:
java.lang.RuntimeException: Unable to instantiate activity
ComponentInfo{com.myapp/com.google.zxing.client.android.CaptureActivity}: java.lang.ClassNotFoundException:
com.google.com.zxing.client.android.CaptureActivity in loader dalvik.system.PathClassLoader[/data/app/com.myapp-1.apk]
I have tried googling, found a few issues, but no real clear or solid answers, most just point to the tutorials above. I am not sure if the tutorials are just outdated or I am being stupid and am missing something key. Been working on this for a few days now and am at my wits end.
If you can help I would appreciate it. To avoid answers regarding if I have done X or X, here is what I have done.
When I test the application, I do briefly see it trying to load BarcodeScanner, but right after I see that it ForceCloses. I am not sure what I am missing, but for references I will post the code I currently have setup to test:
AndroidManifest.xml - http://pastebin.com/qq9q0ZU7
Plugins.xml - http://pastebin.com/dZ5eKPSU
index.html - http://pastebin.com/wvht4ken
If I need to post any other items let me know.
On Android, it is much much simpler than all this you're trying to do. Throw this out and restart from http://code.google.com/p/zxing/wiki/ScanningViaIntent
Ok, so for anyone having this problem, you have two choices. You can use the ScanningViaIntent, as Sean pointed out. It works great, if you need an example look at CommonsGuy. As for the tutorials I posted above to get this working with PhoneGap, my whole problem was, after I imported the LibraryProject I did not go back through and add the files. I am not sure if a setting in my Eclipse is bad. But I basically just right clicked on the LibraryProject, went to Import -> File Structure -> Library Project's original project path, and loaded all of it back in there.
There is probably something wrong with my Eclipse setup, but yea. I now have the BarcodeScanner plugin for PhoneGap working!
I have a minor issue with the way IntelliJ caches files or builds (not sure about terminology here).
Situation Abstract:
Library module
DrawableA
DrawableB
App module
DrawableA
Assume library images are black and white, App ones are color.
The app shows (correctly) the colorful A.
The app shows (correctly) the black and white B (means its missing).
Now I add an image to App project, Drawable B, in color.
If you simply press "run" he will keep using black and white B
If you "rebuild project" he will use the correct one
If you try "Make" and "Compile" manually on Lib and App NO EFFECT
To clarify, this issue is really special. It only occurs if the DrawableB is NOT present in the App module. If you have it, but the WRONG one, and you update it, it works. I assume its an internal caching of IntelliJ, and he does not recognize that I added a drawable (and he has to use it from the App now, not the LIB). Perhaps its something in the google build of Android projects, not enough info about the internal here...
I know, the obvious tip is "do a rebuild of the whole project" - that said, I have 18 App modules, each for one App. The rebuild takes forever (on one of our machines without SSD), and its not neccessary. If I change something in e.g. AppX, I only need to rebuild AppX and the Library. But there seems to be no option for it.
Does anyone know a workaround, like deleting BIN or other cache folders via script? Cant split up the modules in different "projects", would loose refactoring capabilities.
Crosspost here, check before wasting time to answer (this site here is more frequented and faster, but this issue is so specific, cant hurt to ask the developers too)

Try to rebuild project. Smtm i have same problem and it helps me.
Can you try it with the new IntelliJ Idea version 12? It seems to handle cached resources pretty well.
