Receive Drive content notifications in an Android app without a backend



I have to use Google Drive REST API due to the limitation of Android Drive API for my android app. Everything works properly until registering for change notification. From the API docs, the workflow is:


example.com


https://example.com/notifications



Is it possible to receive push notification from Google Drive on an android app without my own backend server?





you'll need an http server running on your phone. There is code on Github that will allow you to embed the server in your app. Dynamic DNS will handle the routing. However, a simple backend to convert the notifications to Firebase Cloud Messaging would probably be simpler.

@pinoyyid thanks for the solution, but if so, my app only receives notification when running that is not practical

Well you could run it as a Service, but nevertheless I agree which is why I steered you towards a simple FCM server.

you'd have define that push notification URL as a Cloud Function HTTP Trigger's URL - which then pushes a Firebase Cloud Messaging notification to an Android client, whenever it is being triggered.
basically, this would be a HTTP push notification sending out a subsequent FCM push notification.





sound complicated, do you have kind of tutorial for this, I am not familiar with backend stuff

@thanhbinh84 have linked some of the documentation, while it obviously would need that one Cloud Function scripted. the GSuite Admin SDK is not even useful here, because one can only pull this information; updated my answer to the least required.

@thanhbinh84 here would be one relevant tutorial: android.jlelse.eu/… while for Drive, one needs an HTTP trigger, instead of changes to a Firebase database, in order to know when to run the cloud function.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

Creating a leaderboard in HTML/JS

Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]&g
