Pixel phones running Android 14 QPR2/3 stop drawing platform views on resume #142978
Description
Steps to reproduce
I've created a new project with flutter create and integrated a simple test view on Android side as per https://docs.flutter.dev/platform-integration/android/platform-views.
The issue seems to be happening exclusively on Pixel devices running the latest Android 14 QPR2 Beta 3/3.1, as well as QPR 3 Beta 1, with confirmed device/build number:
- Pixel 6 running AP11.231215.009 (QPR2 Beta 3.1)
- Pixel 7 running AP11.231215.009 (QPR2 Beta 3.1)
- Pixel 7 running AP11.231215.007 (QPR2 Beta 3)
- Pixel 6 running AP21.240119.009 (QPR3 Beta 1)
Steps to reproduce:
- Launch the app
- Switch to Home Screen
- Open an app or two(camera, phone app etc.)
- Go back to the sample app
Sample project:
platform_view_test.zip
Expected results
The platform view hosted by Flutter app is displayed.
Actual results
The platform view is not displayed, instead the place it used to occupy is rendered solid black.

}
}
class MyHomePage extends StatelessWidget {
const MyHomePage({super.key});
@override
Widget build(BuildContext context) {
final Map<String, dynamic> creationParams = <String, dynamic>{};
return Scaffold(
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: Text("App"),
),
body: AndroidView(
viewType: "nativeView",
layoutDirection: TextDirection.ltr,
creationParams: creationParams,
creationParamsCodec: const StandardMessageCodec(),
),
);
}
}Platform side:
package com.example.platform_view_test
import android.annotation.SuppressLint
import android.content.Context
import android.view.View
import android.widget.TextView
import io.flutter.plugin.common.StandardMessageCodec
import io.flutter.plugin.platform.PlatformView
import io.flutter.plugin.platform.PlatformViewFactory
class NativeView(context: Context, id: Int, creationParams: Map<String?, Any?>?) : PlatformView {
private val textView: TextView
init {
textView = TextView(context)
textView.text = "Hello, world!"
textView.textSize = 42.0F
}
override fun getView(): View {
return textView
}
override fun dispose() { }
}
class NativeViewFactory : PlatformViewFactory(StandardMessageCodec.INSTANCE) {
override fun create(context: Context, viewId: Int, args: Any?): PlatformView {
val creationParams = args as Map<String?, Any?>?
return NativeView(context, viewId, creationParams)
}
