I m trying to figure out why I keep getting an error when tr | Compose

I’m trying to figure out why I keep getting an error when trying to add compose to my project. Haven’t been able to find an answer from searching online, so maybe y’all can help me. I’ll post the stack trace in thread

java.lang.IllegalStateException: ViewTreeLifecycleOwner not found from androidx.coordinatorlayout.widget.CoordinatorLayout{96763ee V.E...... ......I. 0,0-0,0} at androidx.compose.ui.platform.WindowRecomposer_androidKt.createLifecycleAwareViewTreeRecomposer(WindowRecomposer.android.kt:242) at androidx.compose.ui.platform.WindowRecomposer_androidKt.access$createLifecycleAwareViewTreeRecomposer(WindowRecomposer.android.kt:1) at androidx.compose.ui.platform.WindowRecomposerFactory$Companion$LifecycleAware$1.createRecomposer(WindowRecomposer.android.kt:98) at androidx.compose.ui.platform.WindowRecomposerPolicy.createAndInstallWindowRecomposer$ui_release(WindowRecomposer.android.kt:153) at androidx.compose.ui.platform.WindowRecomposer_androidKt.getWindowRecomposer(WindowRecomposer.android.kt:228) at androidx.compose.ui.platform.AbstractComposeView.ensureCompositionCreated(ComposeView.android.kt:200) at androidx.compose.ui.platform.AbstractComposeView.onAttachedToWindow(ComposeView.android.kt:235) at android.view.View.dispatchAttachedToWindow(View.java:22010) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4291) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:4298) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:3087) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:2575) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:9910) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:1010) at android.view.Choreographer.doCallbacks(Choreographer.java:809) at android.view.Choreographer.doFrame(Choreographer.java:744) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:995) at android.os.Handler.handleCallback(Handler.java:938) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:246) at android.app.ActivityThread.main(ActivityThread.java:8512) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:602) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1130)

I’m thinking is because of some dependency, but not sure which one and nothing I’ve tried has solved it

also I’m trying to add a simple composable to an existing screen with a

ComposeView

in the xml

If you're using

AppCompatActivity

, make sure you're using AppCompat

1.3.0-rc01

- only the 1.3 versions set the

ViewTreeLifecycleOwner

that

ComposeView

requires

thanks! I’ll try that. Is this documented anywhere? I haven’t been able to find which dependencies work with compose, so I’ve been a little lost

Compose should throw an exception telling you to use 1.3+, so I’m curious what code path triggers this - how are you adding

ComposeView

/ how are you calling

setContent

on it?

Ian Lake

(Are you calling

setContent

on your

ComposeView

at all?)

Luis Mierez

The

ComposeView

I’m just adding in the xml, and then in

Fragment

I’m calling the

setContent

which passing in my composable function

<androidx.compose.ui.platform.ComposeView
            android:id="@+id/user_section_header"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

updateInfoComposeView.setContent {
            UserInfoSection()
        }

this is an older screen so just want to move a single section that displays some user info. I’m not even passing in any data and I’m just hardcoding everything in the composable until I get something to show up on the screen

Where in your

Fragment

are you calling

setContent

Luis Mierez

onViewCreated

Ian Lake

Then yeah, unless this was the very first fragment in your app, your

ComposeView

will have gone through

onAttachedToWindow

by that point

Luis Mierez

btw I was using an older version of appcompat, I never got any errors telling me that I was in the wrong version though. Updated and will let you know if that worked

Ian Lake

If you're in a Fragment, you'll need to upgrade your Fragment version to 1.3.X

(for the same reason)

Luis Mierez

yeah that one I’m on 1.3.3, I missed the appcompat one

Ian Lake

I wonder if

ComposeView

could avoid throwing in

onAttachedToWindow

and instead wait for you call

setContent

for the first time? Then you'd get the good error message

Louis Pullen-Freilich [G]

Unless I’m missing something,

ComposeView

shouldn’t create anything until is

setContent

is called, no? Only

AbstractComposeView

allows for extra choices in terms of when to set up the composition

Luis Mierez

updating the appcompat version worked! thanks!

Is there a place where which dependencies work with compose is documented?

Like Louis said, you should be getting this error message: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]tlin/androidx/compose/ui/platform/ComposeView.android.kt;l=34

Luis Mierez

gotcha. Not sure why I wasn’t getting that error though

Louis Pullen-Freilich [G]

If you have a small reproducible sample, it would be helpful if you could file a bug, since this is a very confusing crash when you don’t see this error message 🙂

Luis Mierez

not sure if I can come up with a reproducible sample, but I can compile a list of our apps dependencies (some of which are very old) and try to do something with that

either way, updating appcompat worked. I appreciate all the help!
