Gradle Build Fails When Using Density Splits With MinifyEnabled True and not Excluding xxxhdpi

[Scott Olcott]

I have been trying to enable density splits in my application and have run across an error when I don't exclude xxxhdpi from the density split and minifyEnabled true.  This is happening on the 1.0.0-rc4 version and was also happening on 1.0.0-rc2

Here is the relevant portions of my build.gradle that cause this issue to occur.  Adding xxxhdpi to the exclude in splits{density{exclude}} causes the issue to go away.  I was able to modify the densitySplit sample app to reproduce this issue.

splits {

        density {

            enable true

            exclude "ldpi", "tvdpi"

            compatibleScreens 'small', 'normal', 'large', 'xlarge'

        }

    }

buildTypes {

        release {

            minifyEnabled true

            proguardFiles getDefaultProguardFile('proguard-android.txt')

        }

    }

Here is the error message and stack trace:

:app:proguardRelease

Which build tools are you using?

also, do you have xxxhdpi assets?

Please do not send me questions directly. Thanks!

[Scott Olcott]

I am using build tools 21.1.1.  In my main app I have xxxhdpi resources in mipmap-xxxhdpi.  In my sample project that I used to reproduce this I added resources in drawable-xxxhdpi.  Also appcompat which I am using has a bunch of xxxhdpi resources.

Do you have any resConfig properties?

[Scott Olcott]

In my main app I have resConfigs "en".   In my sample app I don't have any.

[Xavier Ducrohet]

And your sample app has the same issue? Could you send it to me?

[Scott Olcott]

Here it is.

[Scott Olcott]

Also, just in case it helps, I am running gradle with JDK 8.

[Xavier Ducrohet]

I'm not seeing the problem with the sample project? I ran ./gradlew assemble and it worked.

[Scott Olcott]

Looks like it is an issue with running the build with Java 8.  I switched to Java 7 and it works fine.

[Scott Olcott]

This is still an issue with the 1.0.0 release.  I can reproduce it with Java 8 only.  I couldn't find a bug created for this, should I create one?

[Jerome Dochez]

yes please file a bug at http://b.android.com

thx.
