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.

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")
        }
    }
}

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.

Answer 3

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

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

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

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

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.

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.

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.

Answer 13

Solution:-

Just deleted drawable-xxxhdpi\background_4.png and re-generated android resources by running ionic cordova resources android --force
