build failing during merge resources with Android Gradle plugin 3.3.0

Question

I have a lot of different flavors for my build that have specific resources and I don't want to clutter my src directory in my project with a bunch of flavor-specific directories, so I add the source sets from another folder in my project prior to the mergeResources task (mergeResources.doFirst). This has always worked for the past several versions of the Android Gradle plug-in (3.1.0-3.2.0 and some of the 3.3.0-alpha versions), but at a certain point, the 3.3.0-alpha AGP started causing build failures during this mergeResources task.

Now I keep getting:

BUILD FAILED in 35s 16 actionable tasks: 15 executed, 1 up-to-date Exception in thread "ForkJoinPool.commonPool-worker-6" java.lang.IllegalStateException: AAPT Process manager cannot be shut down while daemons are in use at com.android.builder.internal.aapt.v2.Aapt2DaemonManager.shutdown(Aapt2DaemonManager.kt:96) at com.android.build.gradle.internal.res.namespaced.RegisteredAaptService.shutdown(Aapt2DaemonManagerService.kt:61) at com.android.build.gradle.internal.workeractions.WorkerActionServiceRegistry$shutdownAllRegisteredServices$1$1.run(WorkerActionServiceRegistry.kt:96) at java.util.concurrent.ForkJoinTask$RunnableExecuteAction.exec(ForkJoinTask.java:1402) at java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:289) at java.util.concurrent.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1056) at java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1692) at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157)

My stacktrace is:

I thought maybe the PNG file was corrupted or incorrectly labeled, but I've run it through a whole bunch of conversions and I get the same error.

During testing, it works fine, but during the release builds is when I get this error. I've resorted to building using AS 3.2 and AGP 3.2.0 for my production builds, which works fine. Also, this is Windows only. It works fine on my Mac.

Oooh this looks super interesting. Would you mind filing an issue on issue tracker so that the Android Studio team can have a look? – Nason

@IzabelaOrlowska I've posted the issue to the tracker. issuetracker.google.com/issues/117900475 – Carving

thanks for filling the issue! – Nason

Got the same after updating to 3.3.0 from 3.2.1. Cleaned everything (cache, Gradle folder) - no luck. Works on Mac but fails on Windows. Which is super sad as I have always done the Android development on Windows, it worked faster there. The resource that fails has size over 2MB. – Antalya

Also, it has nothing to do with Android Studio 3.3 directly. I was able to use AS 3.3 but had to use AGP 3.2.1 for compilation to work on Windows. – Antalya

Answer 1

Updated 19th April, 2019

This issue has been fixed in Android Gradle Plugin 3.4.0.

After upgrading to Android Studio 3.4.0, the temporary fix suggested in the original answer can be removed. Hurray!

Original

This is a bug in AAPT2 in Android Gradle Plugin 3.3.0, when building a project with larger png's (around 2-3 mb and up).

@akong9759 created an issue for this on Googles issue tracker and it has been fixed.

https://issuetracker.google.com/issues/117900475

The problem has been fixed in Android Gradle Plugin 3.5.0-alpha03 and the fix is scheduled to be released in version 3.4.0.

A temporary fix for Android Gradle Plugin 3.3.0 has been suggested on the issue. Add the following to the project build.gradle:

allprojects {
    // Workaround for https://issuetracker.google.com/117900475
    // Remove when upgrading to AGP 3.4 or higher.
    configurations.matching { it.name == '_internal_aapt2_binary' }.all { config ->
        config.resolutionStrategy.eachDependency { details ->
            details.useVersion("3.5.0-alpha03-5252756")
        }
    }
}

Until 3.4.0 comes out this seems to be the best answer, Worked like a charm! – Hypozeuxis

I've tried adding this in my project build.gradle but it doesn't fix anything. I'm curious..does configures.matching need to replace the existing configurations.all part? – Pegram

If you're using nativescript this currently is still the only feasible solution. Thanks for sharing! – Eichmann

Today I updated studio to 3.4.0, gradle plugin to 3.4.0, 5.1.1 in distribution URL. After doing this update, i got an error: "AAPT2 aapt2-3.5.0-alpha03-5252756-windows Daemon #7: Daemon startup failed". Please help. – Lightening

It seems to be the only actual solution for Cordova too – Iotacism

I have Android Studio Version 4.2.2 but I am getting the same error now I added the given code in build.gradle file now I found it is working without any error. – Carltoncarly

Answer 2

I had the same issue. The build would break and mention different png files, like your background_4.png, but only on a Windows PC. The build on a Mac had no problems.

In my case the image size was the problem. Only images bigger than 2MB seamed to break the build. After reducing every image to something lesser than 2MB the build started working again.

Fallacy

Confirmed, also having that issue since I switched to Windows from GNU/Linux. Reducing the size to something lower than 2MB indeed solved the issue. I wonder why that happes though, and maybe if there's a way to tweak it somehow to correctly work with such images – Parody

It's a nice find, but considering that everything worked with 2.2.1 and works just fine with 3.3.0 on Mac with the same project, I certainly am not eager to reduce my file sizes. It looks like a bug on "their" side. – Antalya

Worked for me too. Unbelievable. I just converted all my assets to .webp's and it built just fine. – Galliett

Answer 3

Check your layout xml files carefully in my case issue was duplicate xml

<?xml version="1.0" encoding="utf-8"?>

Mccrea

It's not an issue with XML, but with trying to swap out png files. All my XML resources are fine, otherwise it wouldn't work on my Mac or older versions of AS. – Carving

Answer 4

You need to verify your layout.xml files. There may be something wrong. I got same error and fixed issue on layout file. It worked for me.

Answer 5

i had the same issue while working with android 3.5.3 and the above solution didn't work with me but i found that android studio cant link between the color and vector images my code in vector looked like that

<vector android:height="84dp" android:tint="@color/colorPrimary"
    android:viewportHeight="24.0" android:viewportWidth="24.0"
    android:width="84dp" xmlns:android="http://schemas.android.com/apk/res/android">
    <path android:fillColor="@color/colorPrimary" android:pathData="M8,5v14l11,-7z"/>
</vector>

when i changed @color/colorPrimary to the color code #F44336 it worked fine

<vector android:height="84dp" android:tint="#F44336"
    android:viewportHeight="24.0" android:viewportWidth="24.0"
    android:width="84dp" xmlns:android="http://schemas.android.com/apk/res/android">
    <path android:fillColor="#F44336" android:pathData="M8,5v14l11,-7z"/>
</vector>

i hope this helps

Answer 6

In my case the issue was in Target Level API.

By default API 34 was set.

After changing it to API 33 gradle built my project.

Probably the root cause is API 34 in beta at this moment.

Hope this will help if you are strugging a whole day like I am.

Answer 7

You need to clean up your older caches of gradle and maven dependencies. E.g, try to delete the files under .m2 and .gradle and then Invalidate Caches / Restart ...

Also, can try to disable enableAapt2 by setting it to false inside gradle.properties

android.enableAapt2=false

Undertake

Nope, same issue after clearing .gradle from the project and the .gradle and .m2 from my user directory and invalidating caches /restart – Carving

can post your build.gradle? probably the buildToolsVersion matters. – Undertake

Cleaning out an entire .m2 (1GB+) just because of this? Internet isn't cheap for some people. – Change

Answer 8

From the log It looks like one of your png image might be corrupt, Try replace or remove it and try to build.

\res\drawable-xxxhdpi\background_4.png

Hsining

Is there any way to confirm that it's corrupted or fix the file itself? I've tried opening it in an image editor and exporting as a png, but that didn't fix it. – Carving

Answer 9

If you would change variants it would automatically configure itself... Means if you are going run free(Choose from built Variants) then paid flavor will be red and Vice-Versa.

Thielen

That's not it. I know how build variants work and that wouldn't work for what I need. – Carving

Answer 10

After spending a long day on the issue, I have solved it by simply fetching the GIMP and converting the PNG files into JPG, as suggested by someone in google issue tracking.

It worked miracles, and I did not have to change any other file, package version or setting.

Samal

Answer 11

For me delete all build folders and restart system and reopen Android Studio works in debug mode.

Update:

One of my png was giving error : error: failed to read PNG signature: file does not start with PNG signature I open and export again in png. Now it is working with every build variant. And Delete one zero byte png. Anyone make it beautiful if works/ Thanks

Answer 12

I resolved this problem after reduce the image size.

• noted size difference between the image who caused the problem and other images, you will found it great in size.
