Unable to merge resources, duplicate attr/scaleType error

[lgrimes]

Description

When trying to build our existing app after integrating com.twilio:video-android:5.2.0, the build will fail at mergeStagingDebugResources task with the following errors:

AAPT: error: duplicate value for resource 'attr/scaleType' with config ''.
AAPT: error: resource previously defined here.

We are also using androidx.camera:camera-view:1.0.0-alpha03 which is also declaring a scaleType attribute. This is the error when trying to merge the 2 resources. Have tried updating this to alpha08 and issue persists

.gradle/caches/transforms-2/files-2.1/c7a0ee02aa85f6263deaf25d70997022/camera-view-1.0.0-alpha03/res/values/values.xml:3:5-25:25: AAPT: error: duplicate value for resource 'attr/scaleType' with config ''.

The values.xml file of the video-android

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr format="boolean" name="mirror"/>
    <attr format="enum" name="scaleType">
        <enum name="fit" value="0"/>
        <enum name="fill" value="1"/>
        <enum name="balanced" value="2"/>
    </attr>
    <declare-styleable name="VideoTextureView">
        <attr name="mirror"/>
        <attr name="scaleType"/>
    </declare-styleable>
    <declare-styleable name="VideoView">
        <attr name="mirror"/>
        <attr name="scaleType"/>
        <attr name="overlaySurface"/>
    </declare-styleable>
</resources>

Notes

• We have android.useAndroidX=true
• We also have android.enableJetifier=true
• Tested with both video-android:5.2.0, video-android:5.1.0

Expected Behaviour

The build would succeed and merging resources would complete

Actual Behaviour

The build fails and resources are not able to be merged

Reproduces how Often

Every build. Removing dependency resolves issue

Hey @lgrimes

Thank you for filing the issue. I have reproduced locally. I'll see if I can put together a workaround. The issue seems to be related to clashing resource names between our SDK and the CameraX library.

Thanks!

Hi @aaalaniz, thanks for confirming the issue, any updates by any chance? :)

Hey @lgrimes @fredwu

I was trying to put together a workaround for this issue, but I cannot find any recommended ways of merging attributes with the same name. I did fix the issue by prefixing our VideoView/VideoTextureView attributes, but it does require an update to the SDK itself.

We will ship a fix for this in 5.4.0 and I will update the ticket when the version is released.

Thank everyone!

Fixed in Video Android 5.4.0.

Thanks for filing the issue!

Duplicate value for resource 'attr/scaleType' with config 'DEFAULT' and product ''.
