How to utilize Android Nougat's Direct Reply feature with a NotificationListener?

My app is using a NotificationListener to read out messages from various 3rd party apps, for example WhatsApp.
So far I was able to send a reply if only one chat is unread, the code is below.
However, in the case with WhatsApp, getNotification().actions returns a null object when more than two chats are unread, as the messages are bundled together. As you can see in the pictures below, if the notifications are extended there is an option to send a direct reply as well, therefore I am certain that it is possible to utilize this, also I think apps like PushBullet are using this method.
How could I access the RemoteInput of that notification?
public static ReplyIntentSender sendReply(StatusBarNotification statusBarNotification, String name) {
Notification.Action actions[] = statusBarNotification.getNotification().actions;
for (Notification.Action act : actions) {
if (act != null && act.getRemoteInputs() != null) {
if (act.title.toString().contains(name)) {
if (act.getRemoteInputs() != null)
return new ReplyIntentSender(act);
}
}
}
return null;
}
public static class ReplyIntentSender {
[...]
public final Notification.Action action;
public ReplyIntentSender(Notification.Action extractedAction) {
action = extractedAction;
[...]
}
private boolean sendNativeIntent(Context context, String message) {
for (android.app.RemoteInput rem : action.getRemoteInputs()) {
Intent intent = new Intent();
Bundle bundle = new Bundle();
bundle.putCharSequence(rem.getResultKey(), message);
android.app.RemoteInput.addResultsToIntent(action.getRemoteInputs(), intent, bundle);
try {
action.actionIntent.send(context, 0, intent);
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
return false;
}
}
Some explanation how the above code works: Once a notification is received the app tries to get the actions and checks if the name is in the title of a remoteInput (normally it is in the format of "Reply to $NAME"), if that is found the Action is saved into a ReplyIntentSender class, which, when triggered by sendNativeIntent, cycles through all RemoteInputs of that Action and adds the message to the intent. If more than one chat is unread, getNotification().actions returns null.
Below are two screenshots, the first one where it is working without any problems and the second one where it doesn't.

You can consider this as my suggestion. I have done bit research on this and come up with following conclusions.(Also it looks like you have done plenty of research on this so it might be possible that you aware about what I wrote below)
Numerous apps send Wear specific notifications, and many of those contain actions accessible from an Android Wear device. We can grab those Wear notifications on the device, extracting the actions, finding the reply action (if one exists), populating it with our own response and then executing the PendingIntent which sends our response back the original app for it to send on to the recipient.
To do so you can refer this link (A nice workaround by Rob J). You can also refer this link in this context (Great research work done by Michał Tajchert).(You might need to work around with NotificationCompat.isGroupSummary)
This is what I feel(Might be I am totally wrong)
.actions method returns Array of all Notification.Action
structures attached to current notification by addAction(int,
CharSequence, PendingIntent), Here addAction method is deprecated
one so it might not working as intended.
I am not able to test this at my end otherwise I will love to provide a working solution with code.
Hope this will help you. Happy Coding!!!

Message specific user in a Phonegap/Cordova app using SignalR 2

I am attempting to create a real-time communication capability for a Phonegap/Cordova app. I am using SignalR 2 to handle the communication.
The thing I am struggling with is getting a message to a particular user. Every single example out there shows saving Context.User.Identity.Name, which is useless to me because the remote site's User.Identity context is not shared by my phonegap app.
In essence, I am not authenticating a user in the traditional sense, so I need another way of linking the SignalR connectionID with the username I pass along.
Taken from the official ASP.NET signalr Examples, I have the following code which overrides the OnConnected event. Unfortunately it takes no parameters and expects User.Identity to be not null:
public override Task OnConnected()
{
using (var db = new UserContext())
{
// Retrieve user.
var user = db.Users
.Include(u => u.Rooms)
.SingleOrDefault(u => u.UserName == Context.User.Identity.Name);
// If user does not exist in database, must add.
if (user == null)
{
user = new User()
{
UserName = Context.User.Identity.Name
};
db.Users.Add(user);
db.SaveChanges();
}
else
{
// Add to each assigned group.
foreach (var item in user.Rooms)
{
Groups.Add(Context.ConnectionId, item.RoomName);
}
}
}
return base.OnConnected();
}
Now, maybe what I'd need is to have a version of this method that takes a string as a parameter and then I'd use that as my user identifier.
But how to go about that?

You need to create a new IUserIdProvider for the user and use dependency injection to register your provider and use it.
public interface IUserIdProvider
{
string GetUserId(IRequest request);
}
Register your provider with Global Host
GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => new MyIdProvider());
Usage:
public class MyHub : Hub
{
public void Send(string userId, string message)
{
Clients.User(userId).send(message);
}
}

Login flow for Gigya in mobile app with custom login UI

I'm developing an Android app using Gigya to allow people to register using Facebook and Twitter; in parallel another developer is doing the same thing in iOS. We want to implement custom login UI.
The standard method uses Gigya's own UI and is documented here:
http://developers.gigya.com/035_Mobile_SDKs/020_Android#Logging_in_the_User
Beneath, it simply suggests:
If you wish to implement the graphic design by yourself, use the login method instead.
The standard login method calls a dedicated post-login callback with an onLogin(...) method and all subsequent flows are described as stemming from this event. The other login method calls a standard onGSResponse(...) callback; it's not clear how the response can be used to construct a user so I've set up my implementation to call socialize.getUserInfo. Attempts to call either method have resulted in lots of unusual errors.
As per the Gigya instructions I'm starting up with
mGSAPI = new GSAPI(GIGYA_APP_KEY, this);
mGSAPI.setAPIDomain("eu1.gigya.com");
in onCreate(...) (where GIGYA_APP_KEY is a value copied from our console). I'm calling setAPIDomain because we were getting an invalid data center error (albeit with a 500001 code, not a 301001 code!), which this has fixed.
Facebook login goes through the login flow as I'd expect and then comes back with error 400093 (which the docs tell me is an invalid API parameter, and has the message " Missing parameter: client_id").
Twitter login comes back with 206002, " Account Pending Verification", which seems to make sense; I then call
mGSAPI.sendRequest(
"getUserInfo",
null, //parameters
true, //use HTTPS
this, //the callback
null //a context object
);
and this gives me the error:
Missing required parameter: No secret or signature were provided. Request could not be verified.
The documentation for socialize.getUserInfo suggest a UID is required for web apps, but not for native ones. It mentions no other mandatory fields. I am a bit stuck ... shouldn't the GSAPI object be handling verification, as it's initialized with the API key?

I can give you some direction at a very high level for integrating GIGYA. (Code below is not verbatim) Hopefully it is somewhat helpful.
For a private Android app I had created a Manager object (GigyaManager) that maintained a singleton instance of the GSAPI object.
This singleton GigyaManager was initialized in my application object:
public static GigyaManager getInstance(String apiKey, Context context) {
mGSAPI = new GSAPI(apiKey, context);
}
My GigyaManager class also had a wrapper method for handling the login w/social services:
public void loginWithSocialService(GigyaSocialProvider provider, GSResponseListener listener) throws Exception {
// did the user attempt a social login, and bail out on the registration
// phase?
if (GigyaManager.getInstance().getGSAPI().getSession() != null) {
logout();
}
GSObject providerArgs = new GSObject();
providerArgs.put(GigyaManager.GIGYA_ARG_PROVIDER, provider.name().toLowerCase());
mGSAPI.login(providerArgs, listener, null);
}
This was fired from an onClick listener in a fragment that contained a "login" button:
GigyaManager.getInstance("appKey", getActivity()).loginWithSocialService(GigyaSocialProvider.FACEBOOK, this);
That fragment had to implement GSResponseListener that has the callbacks to deal with whether the login was successful or not:
#Override
public void onGSResponse(String method, GSResponse response, Object context) {
if (!method.equalsIgnoreCase("login") || response.getErrorCode() != 0) {
return;
}
GIGYAResponseWrapper resp = new GIGYAResponseWrapper(response.getResponseText());
// user is attached to login provider?
if (resp.isIsAttached()) {
// start some sort of loader or asynctask to get information about user account
// connected to GIGYA social login
Bundle args = new Bundle();
args.putString(ARG_UID, resp.getUid());
args.putString(ARG_UID_SIGNATURE, resp.getUidSignature());
args.putString(ARG_SIGNATURE_TIMESTAMP, resp.getSignatureTimestamp());
args.putString(ARG_SOCIAL_NICKNAME, resp.getNickname());
} else {
// login success, but this social account is not associated with anything in GIGYA
}
}

How does Skiller send info in multiplayer games [Android]

I am thinking of using Skiller to manage my multiplayer game and had some questions. I was hoping to find some tutorials on how to use it, but I'll have to look through the code and the examples to figure it out. From what I understand, the data sent back and forth in a turn based game (payload) is going to be a string. This means all my information will need to be condensed into a string and then extracted out on the other end?
For example, Pikachu wants to use Thundershock on Pidgey.
Info to send: MoveName("Thundershock"), movePower("40"), specialAttack("55")
(I could put a key at the beginning to help me figure out what is being sent.)
String payload = "Move;Thundershock; 40; 55";
Then the other player's game would take that info and figure out the damage done and send that info back
payload = "Damage; Super Effective; 23"
How does this sound?
SKApplication.getInstance().getGameManager().getTurnBasedTools().makeMove(gameId, event, payload, chatline,
new SKListenerInterface<SKGameMoveResponse>(){
#Override
public void onResponse(SKGameMoveResponse response){
String gameId = response.getGameId();
eTBGameState state = response.getGameState();
String payload = response.getPayload();
String chatline = response.getChatline();
// handle opponent's move – explained in the next section
}
#Override
public void onError(SKStatusResponse response) {
// failed to send the move
}
});

Android Jtwitter, authentication issues

Hello I am having difficulty using the JTwitter functions to authenticate with my twitter application. I always get a "TwitterException"
Here is my method
OAuthSignpostClient oauthClient = new OAuthSignpostClient(consumerKey,
privateKey, "oob");
a) I don't know what the "oob" value SHOULD be, it is the "callbackURL" and in my application on twitter it says "callBack URL: none" so I have tried putting "none", "None", and null where "oob" with no differing results.
then the rest is boilerplate
Intent i = new Intent(Intent.ACTION_VIEW,
Uri.parse(oauthClient.authorizeUrl().toString()));
startActivity(i);
// get the pin
String v = oauthClient.askUser("Please enter the verification PIN from Twitter");
oauthClient.setAuthorizationCode(v);
// Store the authorisation token details for future use
String[] accessToken = oauthClient.getAccessToken();
// Next time we can use new OAuthSignpostClient(OAUTH_KEY, OAUTH_SECRET,
// accessToken[0], accessToken[1]) to avoid authenticating again.
EditText twitterText = (EditText)findViewById(R.id.twitterText);
twitterText.getText();
// Make a Twitter object
Twitter twitter = new Twitter(null, oauthClient);
// Print Daniel Winterstein's status
//System.out.println(twitter.getStatus("winterstein"));
// Set my status
twitter.setStatus(twitterText.getText());
at this point, I'm simply not sure on how to make this work. Wish I could be more verbose about it, but it has something to do with the authentication. Online things I've seen haven't been helpful

Try this as your callback url:
OAuthSignpostClient oauthClient =
new OAuthSignpostClient(consumerKey, privateKey, "callback://twitter");
Remember! After:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
Do the following
override onResume() to get the verification code
protected void onResume() {
super.onResume();
if (this.getIntent()!=null && this.getIntent().getData()!=null){
Uri uri = this.getIntent().getData();
if (uri != null && uri.toString().startsWith("callback://twitter")) {
//Do whatever you want
//usually use uri.getQueryParameter(someString);
//test what could be someString using Log.v("",uri.toString());
//you want the Authorization code which is a couple of numbers
//so you could use oauthClient.setAuthorizationCode(v);
//and finally initialise Twitter
}
}
}
You can use uri.getQueryParameterNames() to get the parameter String names.
#BobVork
I'd just like to add that you'll need to have a callback URL set in the Settings tab for your Twitter app (on twitter.com).
It doesn't even matter what you put in the field, but if it's empty, callback urls will not work.

I'm not sure that's the problem, but it seems like you never set the user name for the twitter object.

Well, I don't know how it is with the Jtwitter API and I don't know enough Java at this point to really understand the inner workings of this code, but have you tried, instead of NULL or None, to try ? instead. That is the callback used with the restful API when making calls from Javascript. Try it out.
