mwdat-core AAR manifest leaks app-level startup initializers

[bddckr]

Summary

The mwdat-core AAR's manifest includes an androidx.startup.InitializationProvider with initializer entries that don't belong in a library:

<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities="${applicationId}.androidx-startup"
    android:exported="false">
    <meta-data
        android:name="androidx.emoji2.text.EmojiCompatInitializer"
        android:value="androidx.startup" />
    <meta-data
        android:name="androidx.lifecycle.ProcessLifecycleInitializer"
        android:value="androidx.startup" />
    <meta-data
        android:name="androidx.profileinstaller.ProfileInstallerInitializer"
        android:value="androidx.startup" />
</provider>

These are app-level initializers that appear to have leaked into the published AAR from the build environment. A library shouldn't be contributing these — they're concerns of the consuming application, not the SDK.

This causes a crash at app startup when emoji2 isn't on the consumer's runtime classpath (which it won't be unless pulled in by another dependency):

java.lang.RuntimeException: Unable to get provider androidx.startup.InitializationProvider:
  androidx.startup.StartupException: java.lang.ClassNotFoundException:
    androidx.emoji2.text.EmojiCompatInitializer

The same risk applies to ProfileInstallerInitializer.

Workaround

Consuming apps can remove the offending entries from the merged manifest:

<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities="${applicationId}.androidx-startup"
    android:exported="false"
    tools:node="merge">
    <meta-data
        android:name="androidx.emoji2.text.EmojiCompatInitializer"
        tools:node="remove" />
</provider>

Affected version

com.meta.wearable:mwdat-core:0.4.0

Still present in 0.5.0. All three leaked initializers remain in the AAR manifest:

<provider
    android:name="androidx.startup.InitializationProvider"
    android:exported="false"
    android:authorities="${applicationId}.androidx-startup">
    <meta-data
        android:name="androidx.emoji2.text.EmojiCompatInitializer"
        android:value="androidx.startup" />
    <meta-data
        android:name="androidx.lifecycle.ProcessLifecycleInitializer"
        android:value="androidx.startup" />
    <meta-data
        android:name="androidx.profileinstaller.ProfileInstallerInitializer"
        android:value="androidx.startup" />
</provider>
