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.
The previous attempt to do this by setting the theme to
Theme_Translucent_NoTitleBar was reported to offsetting touch events on
specific Xiaomi devices.
By default alpha is not preserved for the VD's contents.
We make the window translucent as a side effect of doing so is preserving alpha.
There should not be extra performance cost for setting the window to be translucent as there is only a single window within the VD.

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.

With this, plugins can know whether or not their input connection should
be cached. In very rare cases this can be used by plugins to know how to
more properly handle their own input connections, in cases where they're
overriding typical input behavior themselves.
* 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.
Add views that are added directly to a platform view's window as siblings to the platform view's container view, rather than as children of a full screen container.
This prevents a false-negative for a visibility check from a specific ads SDK (Teads), which [reported the following warning](https://github.com/flutter/flutter/issues/12114#issuecomment-500906158):

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.
