build failing during merge resources with Android

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:

Execution failed for task ':app:mergeMainReleaseResources'. java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2InternalException: AAPT2 aapt2-3.3.0-alpha13-5013011-windows Daemon #0: Unexpected error during compile 'C:\Users\Alex\Documents\Work\Android\project\app\productio n_resources\categories\fitness\res\drawable-xxxhdpi\background_4.png', attempting to stop daemon.

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

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 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

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 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

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 6

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