Prevents NPEs and simplifies the code needed to handle these collections. There doesn't seem to have been a meaningful difference between null and empty collection here. The specific crash was happening when `object.scrollChildren > 0` while `object.childrenInHitTestOrder == null`, which looks like it may be a bug on its own and probably needs further investigation.
The API breaks accessibility highlighting because of
SurfaceView#setZOrderOnTop. Deprecate it since the underlying issue is
an Android SDK one that can't be worked around from within a
SurfaceView.
libapp.so contains compiled application Dart code. On most Android systems,
this library can be loaded by calling dlopen("libapp.so"), which will search
Android's default library directories.
On some Android devices this does not work as expected. As a workaround, this
patch provides a fallback path to libapp.so based on ApplicationInfo.nativeLibraryDir.
Fixes https://github.com/flutter/flutter/issues/35838
* Remove deprecated runBundle APIs
* Remove code related to dynamic patching (including support for multiple
bundle paths)
* Change FlutterRunArugments.bundlePath to be the Android AssetManager path
where the app's assets are located
The previous logic allowed proxying for any view that belonged to one of the platform views' virtual displays which may lead to us allowing proxying for a view that the platform view isn't allowing proxying for, previous logic also didn't account for unattached views.
This change instead delegates the decision to the platform view.
We use the fact that each virtual display has its unique context to associate any view with its relevant virtual display.
A nice side effect of calling the platform view's checkInputConnectionProxy for webviews is that the plugin now has a way to get a handle to the ThreadedInputConnectionProxyView, which may be useful for getting keyboard working on webview's prior to Android N.
The Android embedder had been using a JNI call to get the observatory URI from
DartServiceIsolate. This call was not thread safe and was redundant with the
server status callback mechanism used on iOS.
This patch works around Android's limitations on reflection. With it embedded
platform views that use virtual node hierarchy trees should be accessible on all
Android versions to date.
The workarounds in this PR are brittle. Ideally the methods would be made public
in Android instead so we wouldn't need to employ tactics like these to work
around the missing methods.
`AccessibilityNodeInfo#getChildId` is blocked from any type of reflection
access, but the underlying private member that the getter accesses,
`mChildNodeIds`, can still be reflected on. On Android versions where we can't
access the getter, this patch falls back on reflectively accessing the field
instead. Unfortunately this field is a
[`LongArray`](https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/util/LongArray.java),
a utility data class private to Android. So in this case we're reflecting to
both access the member and actually read data from it, since we need to use
reflection to call `LongArray.get(index)`.
`AccessibilityNodeInfo#getParent()` doesn't have any lucky available underlying
members. However, `AccessibilityNodeInfo` itself is `Parcelable`, and
`mParentNodeId` is one of the pieces of data that's written to a parcel via
`AccessibilityNodeInfo#writeToParcel`. So the fallback for that is to write the
node to a parcel and then read the parcel for the ID in question. This will
break if the implementation details of `AccessibilityNodeInfo#writeToParcel`
ever change. The details have already changed enough in the past to require two
sets of logic for reading from the parcel.
The engine RunBundleAndSnapshotFromLibrary API expects a bundle path directory
containing the application's assets. If the Android embedding is using
AOT ELF library packaging and does not need to extract assets, then create an
empty directory at the bundle path.
Fixes https://github.com/flutter/flutter/issues/34287
Previously AOT compiled Dart code would be packaged as a group of assets
within the APK. This has been replaced by a single ELF library containing
the same data.
#9203 broke the keyboard_resize integration test(see more details in flutter/flutter#34085 (comment)).
This re-lands @9203 and fixes the issue the integration test uncovered by always allowing to hide the keyboard.

Generally what this PR is doing is setting up a delegation mechanism
for Android's onCreateInputConnection.
It works by letting the framework know when an embedded view gets loses
focus(within the virtual display), the framework maintains a focus node
for each Android view that is kept in sync with the focus state of the
embedded view.
The TextInputPlugin is extended to allow for 2 type of text clients a
"framework client"(what we had before) and a "platform view client".
When the AndroidView's focus node in the framework is focused the
framework sets a "platform view text client" for the TextInputPlugin,
which will result in the TextInputPlugin delegating
createInputConnection to the platform view.
When a platform view is resized, we are detaching it from a virtual
display and attaching it to a new one, as a side affect a platform view
might lose an active input connection, to workaround that we "lock" the
connection when resizing(by caching it and forcing the cached copy until
the resize is done).
Additional things worth calling out in this PR:
To properly answer which views are allowed for input connection
proxying we compare a candidate view's root view to the set of root
views of all virtual displays.
We also preserve a view's focus state across resizes.
Note that this PR only wires text for the io.flutter.view.FlutterView
For the new Android embedding some additional plumbing is necessary.

FlutterMain.findAppBundlePath is using the presence of the flutter_assets
directory as a signal that the app is initialized. For consistency,
FlutterMain will run the resource extractor at startup and create
flutter_assets even if no resources need to be extracted.

Since this class implements equals() and hashCode() it should either be
final or handle subclasses in equals(); given this is unlikely to be
subclassed, making it final is the simpler option.
The AccessibilityViewEmbedder was not delegating a11y events coming virtual nodes(of the embedded view) that were not previously traversed by the a11y framework.
It turns out the a11y framework might leave parts of the tree untraversed in some circumstances, changed the behavior to create an originId<-->flutterId mapping on the fly when an event is delegated from a not previously traversed node.
Fixesflutter/flutter#30010.
Delegate a11y events and action to/from embedded Android platfrom views.
This handles delegation of:
* AccessibilityNodeProvider#performAction
* ViewGroup#requestSendAccessibilityEvent
* View#onHoverEvent
Additionally updates the currently input accessibility focused node state that is
tracked by the a11y bridge when an embedded view's node is focused.
