I have been working on this app for a while and a couple of days ago i came across this error message when I try to build the project:
Error:java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: Error while executing process C:\Users\USER_NAME\AppData\Local\Android\Sdk\build-tools\26.0.3\aapt.exe.
Also everytime I use R. (for example R.Drawable) it says cannot resolve symbol R.
I already tried to change the buildToolsVersion to the most recent version, added android.enableAapt2=true to the gradle.properties, cleaning and rebuilding the project but nothing seems to help.
I´ve been trying to solve this problem for a while, I've found a lot of similar questions on StackOverflow, but don't seem to be able to fix it despite of the several attempts to do it. If someone were to help me would very much appreciatted.
I'v created a new android project in vs 2013 and installed Android.Support.Library.v7.AppCompat package and dependencies. But when I build the project, I got an error that says
resource directory
'[ProjectPath]\obj\Debug\resourcecache\B81A750477D10031D1844681B0F7EB17\res'
does not exist file: [ProjectPath]\AAPT
I'v cleaned the project
reopen it
rebuild it
but not help me.
I have encountered the same issue as you and have found a solution. I know this has been a long time since your post. Just put the solution here to help someone encounter similar issues.
My project can be built successfully previously, so this error must be caused by some kind of settings. A reasonable explanation and solution can be found in this link: http://smstuebe.de/2016/10/29/fix-android-app-compat/
This is caused by the incomplete Android SDK packages. The normal clean/rebuild won't help. Even if I reinstalled VS2015+Xamarin, I still have this issue.
So try the above solution if you came across similar issues.

"cannot resolve symbol R" in Android Studio
(100 answers)
Closed 7 years ago.
I've been working on an app and all was going well, everything was working fine. Then I modified some code in my main activity, and when I tried to run the app, there was an apparent error in my code and the build failed.
After this, all the references to my layout files were no longer working (i.e., R.layout.) R was red and hover over says "Cannot resolve symbol R".
Searching you will find dozens of posts that propose many fixes, like: Clean Project; Rebuild Project; Sync Project with Gradle Files; Invalidate Cashes / Restart; Check xml for errors, restart Studio, etc... I've tried them all.
NONE OF WHICH WORK IN MY SITUATION.
My code is working and without errors because I can create a new Android Studio project, and add my classes and resources. The new Android Studio project will run the the SAME CODE under a different package name.
I encountered this same problem a while back and I vaguely remember deleting something from my project folder (might have been a folder or file). I don't remember what I deleted, but it did fix the problem.
Thanks for any advice.
I finally got Android Studio to build without errors, but honestly I don't know how this happened. It was very puzzling that I could have a project that worked and several copies that didn't (I must have re-created my project 10 times from scratch) each time I would copy the project to an archive directory and start over. One of my build requirements was I needed to compile on Jelly Bean, and I think Android Studio sets some sort of defaults when you open a new project with a Blank Activity. Anyway, each time the R. error occurred the build warning would display this:
<style name="Base.Widget.AppCompat.Spinner.Underlined" parent="android:Widget.Material.Spinner.Underlined
But my code does not contain a spinner, so I really can't figure out where this is coming from. In fact I've tried to replace files in one of my inoperable saved projects with the files from my working copy (manifests, code, gradle.build, etc.) yet once inoperable, it seems a Studio project will remain that way.
I wish I could reproduce the problem but I cannot.
WTF! After thinking I had resolved this the problem, it is back again. From my working project I did 2 things. Added a very simple activity, and added it's reference to the manifest. Tried to run the project and get the SAME error again, referencing the a spinner. The Gradle build message is:
C:\CargoBay\Android\LandApp\app\build\intermediates\res\merged\debug\values-ldltr-v21\values-ldltr-v21.xml
Error:(3) Error retrieving parent for item: No resource found that
matches the given name 'android:Widget.Material.Spinner.Underlined'.
I removed the new code from my project, and it still won't build.
I don't know what to think now.
In Android Studio select your project folder, go to VCS / Local History / Show History. Show History will list any files that were moved or deleted, and give you an option to restore the file.
If you select your main activity code, it shows the history of code changes, and you can restore to previous code that was working.
I have no Idea what is happening, last time when I finished my app I build its release apk and all was working just fine as expected but now today when I tried to make that pproject again and to make another apk I am getting the following error.
Error:Execution failed for task ':app:mergeDebugResources'.
Crunching Cruncher common_signin_btn_icon_pressed_light.9.png failed, see logs
I have no idea how to resolve it I have serached and found restarting Android studio and clean the project would remove it , doing this many times has no effect on this error. I have even restarted my machine but the condition of error in same.
In the logs I have seen that this png file is from the library I added , so just for testing I removed that library and tried to build then it started to give me same error with different png file name in other library. So how to fix this issue ?
My Questions are :
How can this issue be Solved ?
Have some one faced this problem too ?
Is this problem has been reported to google ?
Why in android we do not have any stable platform for development as IOS have ?
Try to remove "builds" folders and do rebuild. But soon, the whole thing in a long file name. Read this answer. By the way, you looked logs? Maybe this is not the PNG? You have not sent the log and did not specify the version Gradle.
Believe me, iOS developers have own problems.
I am trying to fix a problem in Eclipse for like 3 hours and I haven't made any progress. Tomorrow is the customer coming to look at my app, and I have no time left. This is really frustrating!
This morning when I was coding and I wanted to run my app on my device Eclipse crashed all of a sudden. 'aapt.exe has stopped working'
After this Eclipse wasn't starting anymore. It froze at the splash image.
I looked on the internet and tried different solutions like going back to Java SE 6 update 20, changing .ini file etc. in the end reinstalling Eclipse did the job.
Shortly after that the 'aapt.exe has stopped working' returned. I found a solution by changing my projects target. 1.5, 1.6, 2.2 doesn't matter, as long as it's different than the one before.
Now I get the Error generating final archive: java.io.FileNotFoundException: C:\xxx\bin\resources.ap_ does not exist error.
I tried clean but that doesn't work. Deleting and automatically regenarting R.java also didn't work.
I ran the same code in Netbeans with the Android plugin and there it gives me the 'aapt.exe has stopped working' again :(
Please guys, how can I fix this?
Edit:
I think I may have found the reason. These are the error lines in the console:

[2011-01-17 16:37:20 - gegevens.xml] Unable to resolve drawable "com.android.layoutlib.utils.ResourceValue#267e33de" in attribute "background"
The file it's talking about is 'bg.png'. It's a small png file which I repeat in a .xml file.
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/bg" android:tileMode="repeat" />
This file has worked from the first time without any problems.
I deleted it from the drawable folder, waited for an error message, and then added it back. The red x next to the foldername got away, but still nothing different...
A shot in the dark, but if it's just the one PNG file could you delete it from the project and add it back? There must be something breaking the resources file.
I just encountered the same error after performing an SDK update withing Eclipse (Indigo). Normally I would either delete the errors and try to rebuild or clean with success, however this time it didn't fix the problem.
Finally I went to the android sdk folder and manually updated. Upon coming back into eclipse I got the error again, but without rebuilding or cleaning I was able to launch the application onto the device by pressing play for a second time.
EDIT:Apparently this problem is intermittent, as I am now once again unable to run on the device, or export the signed apk.
SOLVED: The problem stems from a corruption in the .metadata folder. I discovered this by re-installing Indigo, but when doing so I didn't remove the original workspace folder. The problem of course showed up again. I deleted the .metadata folder completely, which effectively resets all of your eclipse configuration settings. All deployments and signing work flawlessly now. Just had to setup the environment to my liking again, which takes a few minutes as opposed to the hours I spent troubleshooting this.
I just ran into this same problem after importing my project from another machine, but didn't have any errors in the console like the OP. I unchecked Project->Build Automatically and then did Project->Clean and this solved my problem. I was actually missing several files in the bin/ directory for my project and this fixed them all.
I think this error can come up for a variety of reasons. The following solution is only known to be specific to the same error message appearing when using ADT 14 (released yesterday) with build output set to Verbose:
I ran into the same error using Eclipse 3.7 (Indigo) after upgrading to ADT 14 and SDK 14 on all projects including newly created ones. I found a workaround someone posted on the ADT bug tracker, which is basically to switch Eclipse Settings->Android->Build->Build Output from "Verbose" to "Normal". The post is here.
In my scenario, yesterday upon open Eclipse was trying to download updates and I cancelled it since I was using my cellphone hotspot. I tried the metadata folder delete solution mentioned here and didn't work for me. Going to Window->SDK Manager and updating everything seems to be my solution.
I had the same issue in that I added some images into each resource directory and unfortunately named them .png. There were in fact jpegs and the eclipse plugin was flagging this (unbeknown to me in the console)
The issue I found was that if you clear the console then the logging info is lost and it doesn't log anything again!
Changing the extension from .png to .jpg fixed my issue
Above solution didn't worked for me.
The way I did that is updating not only ADT but SDK as well. To do that just go to Android SDK Manager and just download updates.
IT WORKS!
It's very meaningless but changing build mode from verbose to silent did the trick! Nothing else (cleaning project, re-opening , re-installing) did.
Try running clean, but also uncheck build automatically and click "build project" under the "Project" menu. Once you build manually, you can re-check the "build automatically".
I would also shutdown eclispe, and then kill adb
> adb kill-server
Sometimes this error happens when you create ninepatch with wrong black dots/lines. For example right and bottom lines must be solid with no dashes or empty regions.
Try in
windows-> peferences -> android -> Build -> Build Output
Silent

In some cases, this error will disappear after fixing upstream errors. In my case that was a version incompatibility in 'fullwebview.xml'.
There, 'layout_width'/height was set to a value not supported in my build target, 2.1. Changing the value to 'fill_parent' solved the issue.
I encountered this same error but then I saw that my layout.xml was not catching an error for a TextView whose android:text="#string/my_unmapped_string string resource was not mapped in strings.xml. So when I viewed the graphical layout it was showing:
Couldn't resolve .....
When I mapped the resource properly and ran the project again, it worked fine and that bin\resources.ap_ does not exist error was gone :)
In my case, it was the file add-icon.175x175-75.png (valid file name, but invalid resource name) copied into res/drawable by mistake. After removing this file, Eclipse did (in April 2015) a few successful builds with incorrect sources, and only then began to behave sensibly, showing me missing resources and malformed XML (I changed the layout).
