I was coding these past two weeks and it was compiling/running fine. Bear with me on the history as it might be relevant to the final issue.
One morning I start getting modules not found error and gradle warnings, out of nowhere.
I solve it then proceed to have a "Default activity not found". After I made sure I had a launcher activity in the manifest file, I figured I had a much bigger problem :
80% of my layout XML (in the /res folder) Are now containing chunks of my java code, in a completely random manner.
The icing on the cake : when I rollback to previous commit, as old as 2 weeks ago (that where running 100% fine), they also have the "broken xml java layouts"
It's one of the weirdest things that happened to me for a long time, please share anything that might give a clue.

Noob Android Studio 3.6.1 on Mac Mojave developer here. I have a very simple app with a few activities. Every so often, the Kotlin class for one of the activities will complain of an unresolved reference to the corresponding layout XML file.
For example, in the Kotlin Class (TraceActivity.kt), I have the following code:
setContentView(R.layout.activity_trace)
and the corresponding XML file lives at:
MyApp/app/src/main/res/layout/activity_trace.xml
All pretty standard stuff I reckon. But setContentView would complain that it couldn't resolve activity_trace. This has happened on a few occasions, and I discovered that restarting would resolve the problem. But this morning, it isn't helping. And it's also started complaining about some of the strings I've added to strings.xml
I managed to get round the errors by making use of the full names for each of the items e.g.
com.mysite.myapp.R.layout.activity_trace
and
com.mysite.myapp.R.string.my_message
So my guess (as a noob) that somewhere it's losing track of where it is. And yet my other activities are perfectly happy when I omit the full location. Can anyone offer some insight here? Thank you - SO is awesome.
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.
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?
I know this is a rare question. Even if there are people using MyEclipse for Android development is doubted :(
The annoying thing is that after I modified my Android project (like an Activity class of a xml file), the project remained the same as it was when I imported it.
I thought there is an important feature that demonstrates this error: When I run my Android project and the console reported that "Activity not started, its current task has been brought to the front". This line occurs because the project didnt changed while as a matter of fact I did change the project and saved it.
Is there anyone has the same problem like me?

This was what I did: first, I modified one of my activities by commenting out the Toast functions; and then, I ran it however the Toast line still showed on my Genymotion emulator
As the title says, I m having problems with eclipse every now and then. To list few,
Missing R (the most frequent issue)
Conversion to Dalvik format failed with error 1
Cannot find resource
etc..
I tried many solutions already on SO, this and this and this as well. However the issue still persisted.
I checked and ensure that there was no issue with the xml. I must have cleaned my projects more than n number of times. But the only thing that helped (and is now what I have started doing frequently when any of these errors pop up) is restarting Eclipse. Sometime the error goes in one restart, sometimes two.
Even though this restarting has helped me most of the time (almost all), it is at times very frustrating as I loose good amount of time because of it. So I want help to find some solution here.
Note: My Eclipse says version (Android DDMS - 22.6.2.v201403212031-1085508). Also this has occurred for different projects so I do not think that this should be code specific (I may b dumb for this point). (Also the log cat doesn't point to any specific part of the Projects apart from a red highligt error)
