GCM: Yet another BIND_JOB_SERVICE permission error — IntentService to JobIntentService



Issue: since I now need to target Oreo to submit apps, I have to change my RegistrationIntentService to inherit from JobIntentService instead of IntentService. I am still using GCM, but that should make no difference. Note that this is Xamarin C# code.



The error is that I always get an exception in my static EnqueueWork method saying:



Scheduled service ComponentInfocom.emergencyuniversity.EUAlert/md58d0653b4094c2dbc798f6d984e1c1386.RegistrationIntentService does not require android.permission.BIND_JOB_SERVICE permission



I've changed OnHandleIntent to OnHandleWork, and I now call the static EnqueueWork convenience method in places where I used to call StartService.


var intent = new Intent (this, typeof (RegistrationIntentService));
RegistrationIntentService.EnqueueWork(this, intent); // instead of StartService(intent)



My EnqueueWork, that gets the exception:


public static void EnqueueWork(Context context, Intent work)

Java.Lang.Class cls = Java.Lang.Class.FromType(typeof(RegistrationIntentService));
try

EnqueueWork(context, cls, GCMEUA_JOB_ID, work);

catch (Exception ex)

Console.WriteLine("Exception: 0", ex.Message);




In the manifest, I added:


<service android:name=".RegistrationIntentService" android:permission="android.permission.BIND_JOB_SERVICE" android:exported="true" />



I've also tried exported false, and putting that permission in a bunch of different places.



One other change I made was removing the following due to compiler errors:


public RegistrationIntentService() : base("RegistrationIntentService")



In addition to the Android docs, I have probably read every post imaginable about this, including:



https://android.jlelse.eu/keep-those-background-services-working-when-targeting-android-oreo-sdk-26-cbf6cc2bdb7f



https://medium.com/til-kotlin/jobintentservice-for-background-processing-on-android-o-39535460e060



JobService does not require android.permission.BIND_JOB_SERVICE permission



Why do I still get this error? Any help would be greatly appreciated. Thanks.





"I am still using GCM, but that should make no difference." - Yes it does. GCM is now officially deprecated. The reason why devs are encouraged to migrate to FCM is simply because it's the latest version. It contains fixes for bugs that existed during GCM. If you still continue to use GCM, then there's no guarantee about it's behavior anymore.

I agree that I need to move to FCM, and I will do that very soon, but even though it was deprecated in April I can't believe Firebase would leave me high and dry. There must be something wrong with my EnqueueWork code.

That being said, the first thing I tried was to bump the priority of the GCM message to high, as that is supposed to whitelist you. That didn't work, however, so I wondered if that only applied to FCM. But I still think it is possible to solve this. I just haven't figured it out yet.

Well -- it's a process. Got past the BIND_JOB_SERVICE error by putting: Service(Name = "MyPackage.RegistrationIntentService", Permission = "android.permission.BIND_JOB_SERVICE", Exported = true)] to the C# file for the service. Next error is android.support.v4.content.ContextCompat being inaccesssible with com.google.android.gms.iid.zzd which means I undoubtedly have to update the GooglePlayServices nuget stuff, etc. Which is not working either. Eventually, I imagine I should be able to get past all this.

OK, this is solved. The last issue was solved by upgrading to a later NuGet package for Xamarin.GooglePlayServices.Gcm, and its associated libraries. Everything now working correctly.

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.

Creating a leaderboard in HTML/JS

Image
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]...
