If I try to run a composable @Preview on a device, I get an error of the sort: https://stackoverflow.com/q/68554294

I’ve been able to resolve this by adding these overrides in androidTest/AndroidManifest.xml

<activity
            android:name="androidx.test.core.app.InstrumentationActivityInvoker$BootstrapActivity"
            android:exported="false"
            tools:node="merge"
            tools:overrideLibrary="androidx.test.core"/>
        <activity
            android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyActivity"
            android:exported="false"
            tools:node="merge"
            tools:overrideLibrary="androidx.test.core"/>
        <activity
            android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyFloatingActivity"
            android:exported="false"
            tools:node="merge"
            tools:overrideLibrary="androidx.test.core"/>

But it surprises me that the androidx.test.core package is not setting android:exported on its own.

[Chris Fillmore]

The reason I raise this in #compose is I only have this problem running the @Preview, I don’t have trouble building otherwise

[Chris Fillmore]

Should I file an issue? Any insight here?

[Chris Fillmore]

Btw I have set targetSdk = 33. If I roll back to targetSdk = 30 it avoids this whole issue altogether, as expected.

Sorry for the backwards-ness of this thread, but here is the original error, when I build without the manifest overrides

androidx.test.core has set those flags for over a year now - as of Test Core 1.4.0. What version are you using?

[Chris Fillmore]

Sorry I forgot to mention this. Initially I was using 1.3.0, but tried 1.4.0 and the 1.5.0 alpha.

Next week I'll see if I can isolate a repro

[Chris Fillmore]

I was able to fix this by updating androidx.test.ext:junit from 1.1.2 -> 1.1.3

Thanks for responding
