Early WIP

This is an early WIP to save my place. I created a new interface, nsINativeAppService that has two methods:

jsval getApps(in nsIDOMMozActivityOptions options);
void launch(in jsval appData,
            in nsIDOMMozActivityOptions options,
            in nsIActivityUIGlueCallback onresult);

Still haven't quite figured out how I'll correctly return things to the apps. Android gives us a content provider URI, which can then be used to access the real data. I haven't seen a clear spec for what sort of data apps expect in return, and I imagine there isn't one, so I'll just have to have some special case code to reformat Android apps results into the equivalent Gaia app ones? That sounds painful...

The opposite path will have to be done with synthetic apks, but has similar problems getting the data returned from Gecko into a ContentProvider. Still thinking my way through this....

There's no spec indeed. Each activity is free to define its own data transfer format.

WIP for mapping and launching web activities as intents

A WIP based off of wesj's previous patch. Added a mapping mechanism within NativeAppService to map the Web Activity name, type, and data to the equivalent (or as best as we can) Android intent action, type, and extras. Have not completed the mappings yet, but would like feedback on the way I am doing it.

New WIP with a simplified implementation that uses Android's intent chooser for picking the appropriate activity to handle the WebActivity. This assumes that all webapps will have registered with intent filters with a synthesized APK. 

All that is needed from here is determining rest of the mappings from Web Activities to Intents. wesj / myk, do you know if there is something like this in the synthesized APK work? We need to make sure that the mappings are equal in both (and can share the same code to do it).

I think jhugman has done some work to determine these mappings, or at least a subset of them.  cc:ing him and asking him for info on that.

String#isEmpty() was introduced in Android SDK 9, but we support as low as 8. Instead, use TextUtils#isEmpty (which will also cover the null check for you).

OK, so here is where I start to get confused. A few of these correspond to the Firefox OS activities Wes linked me to (https://developer.mozilla.org/en-US/docs/WebAPI/Web_Activities#Firefox_OS_activities). But most of them -- activity, createShortcut, delete, edit, insert, main, paste, run, search, send, setWallpaper -- are not. How are we choosing the the activities that get listed here?

The list of all ACTIONs at http://developer.android.com/reference/android/content/Intent.html is quite large. The ones here are just a small subset of these, so I'm curious why these were picked. Is there some other list somewhere outlining the functionality we want to support? Or were these picked arbitrarily?

We should probably check `name in activityMap` before doing this, and if that condition evaluates to false, throw an error with a clear message. Since this is an API that web pages will be using, we'll want to avoid cryptic exceptions.

What does FxOS do if multiple MIME types are given? We should probably do our best to make sure behavior matches between platforms as much as possible so apps don't exhibit different behaviors on different platforms. In this case, we might need to iterate through the array, firing a separate request for each, until Android gives us a result back.

From the Android/synthesized APK pov: 

We are able to generate IntentFilters from WebActivities declared in the app's manifest (we don't yet, but it's relatively easy).

Because it is the synthesized APKs that are catching the Android intents, we won't need to provide an Activity chooser of our own – we just use Android's. This is exactly as intended.

However, a couple of things bother me at the moment: 

 * we should provide a standard set of WebActivities, in the same way Android does. Lessons from the Android world would suggest that the community hasn't been very good at adopting community lead standards (see the http://www.openintents.org/intentstable for a repo of intents that no-one uses). My first port of call to find these out would be finding out what use Firefox OS makes of them. WesJ's link is a good start.  
 * WebActivities kinda sorta work like the Intent system in Android, but we'll be unable to support anything but things that invoke a UI. i.e. Android Activities only. AFAIK, headless Gecko doesn't exist yet, and until it does, and is well understood, it's going to be difficult respond to things like ContentResolvers and Broadcast intents. Think: no headless access to data provided by other apps, no responding to phone events, e.g. geo-fencing. The Android Intent docs do provide a bunch of constants, but many of them are not Activity actions.
 * The way we've talked about implementing the synth APK WebActivities mostly depends on the developer registering them in the manifest.json. This does not take into consideration: a) programmatic registration, b) registration by web /sites/. This second point is most difficult, but I don't think this is the right bug to say why.
 * Calling out to WebActivities should not preclude Android Intents: i.e. the mapping should be bi-directional.
 * Whatever mappings we chose should be kept in sync with the APK Factory used to generate APKs from webapp manifests.
 * Especially with this issue, we have an enormous impedance mismatches going on: FirefoxOS/Android. Personally, I think the intents system and putting it at the heart of the OS is one of the few things that Android gets completely right.

More specific feedback for this patch: 
 * I see no reason why the mapping needs to be in Javascript.

Is there code anywhere for where this mapping will happen? If not, is this something that should be worked on in this bug, or are you planning on doing this? I think we could at least propose an idl for this mapping service.

Is there a bug/etherpad/wiki to determine these?

Great, this is what I assumed.

Ideally, we should be able to use the same code to do this, so nothing gets out of sync.

I don't either, but whatever we build should be easily used by both Fennec and the APK synthesizer.

No. The IntentFilters can either be registered programmatically in Java (but would need to be done in the synthesized APK), or via the APK's AndroidManifest.xml, in, ahem, XML.

That's JS => XML, Java, defining the /filter/.

Not that I know of. Would suggest a Wiki page.

Yes, that would be nice. 

Conceptually this is: 
/Intent/ => WebActivityHandler

From an implementation details p.o.v. I'd be wary of premature code sharing – it isn't clear to me that it's possible in the general case: if we see that the two systems are both systems of locks and keys, then we are mapping lock1->lock2, key2->lock1, key1->key2 i.e.

 * in APK-Factory we're mapping WebActivity filters (lock1) to IntentFilters (lock2).
 * in SynthesizedAPK, we're mapping WebActivity filters to IntentFilters again, but this time we must use Java.
 * for incoming intents, in Fennec, we're mapping Intents (key2) that match IntentFilters (lock2) to WebActivity filters (lock1). It's not immediately obvious that Android can tell us which IntentFilter a received Intent matched.
 * for outgoing webactivities, in Fennec, we're mapping MozActivity (key1) to Intent (key2)
 
It should be noted that none of the behaviour described in this comment is implemented.

Talked to josh about this, and I agree that trying to share this is probably premature. I think we're just going to do the initial mapping here. We should try to make it easy to extend/change. A wiki page to detail things would be nice as well. You can just start one somewhere inside https://wiki.mozilla.org/Mobile/Fennec/ . Once we got some basics checked in and the WebApps/Android team are both happy, we can move it over to somewhere near https://developer.mozilla.org/en-US/docs/Web/API/MozActivity.

A mappings table has been added to the project wiki page at [1]. This will serve as a reference spec and place for discussion on:
  1) which actions should be supported
  2) how they (and their associated data) should be translated to Android

I think we need to move this up into the "find" function above:
http://mxr.mozilla.org/mozilla-central/source/dom/activities/src/ActivitiesService.jsm#124

but that's a bit tricky since its using an indexedDB herlper to send results back. However, with the new Synth APK's stuff, we might not need to use the IndexedDB stuff at all. i.e. Any webapps that handle intents will register for them in their APK's, so this whole thing is now un-necessary. We just replace the ActivitiesDB on Android with our own implementation and not use the WebApp DB at all...

The enum isn't really that helpful if you do things this way. You could remove the name and then use:

WebActivityMapping mapping = Enum.valueOf(Mapping.class, name.toUpperCase()).mapping;

or a HashTable of some sort would probably work just as well:

Still need advice on this part. It seems to me that it would make more sense to override Activities so that all startActivity() did was send the MozActivity options to Java.

I looked at the different web activities used by Gaia and found that 'type' and 'uri'/'url' were used quite often, so I made a BaseMapping class to handle these situations which I used to add more mappings really easily. Having base classes like this was the motivation for doing a less generic method like getIntent(JSONObject).

Let me know what you think!

This result will have a bunch of things in it that content probably shouldn't know about. We should clean it up, or maybe it should just contain data that we'll send to the page in a separate object. i.e Java returns:

{ guid: something, type: "Prompt:Return", data: results }

and you'd just pass the data back to the page.

Sorry to go back and forth here. I think we should wait to get some feedback from fabrice, but after thinking about this a bit, I think we should do this inside the sucessCb, and pass the results we found there to the nativeAppService.

I want to make this a bit general so that it could work on other platforms. Those platforms might not have something like the synthetic APK, so this would let them choose to use or ignore the webapps that were found. Right now they basically have to ignore them (or duplicate this database code...)

It's not 100% clear to me how all this works, but by doing that you remove all chances to use activities registered from manifests. Is that what we want on Android? Are you converting them to native intents while building the apks?

02 - Pass activity options instead of name through nsIActivityUIGlue

Some background on how this works with synth-APKs on Android:

All open web apps are packaged up as native APKs (installable Android apps) that have all of their web activities translated into Android intents (this work is separate from this bug). Because of this, we do not use the ActivitiesDB that B2G uses to find eligible apps, so all of our inter-app communications happen via Android's native intent system. This also allows webapps to talk to regular native Android apps as well (yay!).

What's going on in these patches:

My strategy with the modifications to nsIActivitiesUIGlue is to allow an implementer of the interface to have the option to handle the activity by providing all of MozActivity options (rather than just the name) to the implementer as well as a callback to deliver the results (if applicable). This is great for Android and could be applicable to Windows too [1] in the future. Of course for B2G we can safely ignore this new callback.

I tried to comment as much as possible, but definitely point out any areas where it's unclear what I am doing.

Pull this out of the synth-apks ifdef and instead lets wrap it in a #ifdef NIGHTLY_BUILD. I think we'll eventually want to ensure that (at least for the web, maybe not apps), this shows a prompt to the user.
