Android auto manifest merger failed: attribute is also present at

Question

I'm currently trying to build a hello world app as my first android auto app. Earlier, when I was trying to run the app it was giving me some minSdk error and I managed to fix that. Now, when I try to run it, it gives me this error:

Manifest merger failed : Attribute meta-data#androidx.car.app.CarAppMetadataHolderService.CAR_HARDWARE_MANAGER@value value=(androidx.car.app.hardware.ProjectedCarHardwareManager) from [androidx.car.app:app-projected:1.1.0] AndroidManifest.xml:34:17-86
    is also present at [androidx.car.app:app-automotive:1.1.0] AndroidManifest.xml:44:17-87 value=(androidx.car.app.hardware.AutomotiveCarHardwareManager).
    Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml to override.

I've been trying to follow the instructions here on how to edit the manifest file and everything looks fine according to the instructions.

Here's the AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

        android:required="true" />

    <application

        android:roundIcon="@mipmap/ic_launcher_round"

                <category android:name="androidx.car.app.category.POI"/>
            </intent-filter>
        </service>

        <meta-data
            android:name="androidx.car.app.minCarApiLevel"
            android:value="1"/>

    </application>



</manifest>

Answer 1

Since you are targeting Android Automotive in your manifest, you can get rid of the following dependency in your gradle file:

    implementation("androidx.car.app:app-projected:1.1.0")

That should fix the conflict you are having.
