Make the GeckoAppShell.cameraCallbackBridge callback use the new native
JNI bindings. Also refactor the relevant code in GeckoAppShell and
CameraStreamImpl.
The ANativeWindow methods in AndroidBridge are just wrappers around
ANativeWindow calls in the NDK. We should just use those calls instead
of going through the wrappers.
Remove the presentation methods from nsWindow/AndroidBridge now that
they are not used. This also eliminates gGeckoViewWindow from nsWindow.
NS_PRESENTATION_WINDOW and NS_PRESENTATION_SURFACE constants are added
for GetNativeData/SetNativeData to provide replacements that support
multiple GeckoViews/nsWindows.
Replace old flags in WrapForJNI usages with new flags. The calledFrom
and dispatchTo flags are set based on whether the method is native or
non-native, and how the method is used.
Also fix testEventDipatcher to respect NativeJSObject's calledFrom =
"gekco" flag, by moving a test to Gecko thread.
We need to register the Java UI thread in native code very early in the
startup process, before libxul registers its JNI entry points. So it
makes sense to register the Java UI thread in mozglue.
Refactor the notification-related methods in GeckoAppShell. In
particular, combine showPersistentAlertNotification into
showAlertNotification, and move code out of AndroidBridge.
Add a native method in ZoomedView to request zoomed view data. The
native method is implemented in the ThumbnailHelper class on the C++
side because it shares a lot of code with the thumbnailing code.
Add proper synchronization to the UI thread task queue so we don't run
into race conditions. Also use UniquePtr to manage the contained task,
to fix a previous memory leak.
When we have a Java exception in native code, the Java stack in the
exception will not be very useful because the top frame is the native
entry point. In this case, the native stack is more useful. However,
currently we don't get a good native stack in this situation because we
go through Java when handling the exception, and the native stack we get
will have a lot of unknown frames inside libdvm or libart. This patch
makes us stay in native code when handling an uncaught exception from
native code, so that we get a good native stack.
When getting nsAppShell from another thread, there could be a race with
nsAppShell being destroyed on the main thread. This patch makes the raw
nsAppShell pointer only accessible from the main thread, and use a
static mutex to coordinate accessing nsAppShell from other threads.
This patch makes GLContextProviderEGL create EGL surfaces through
nsWindow/nsIWidget on Android. nsWindow then calls GLController in Java
to actually create the surface.
