Comment exécuter un travail d'arrière-plan avec Android-Job

Question

J'ai découvert la bibliothèque this qui semble être très puissante, mais je n'arrive pas à comprendre comment l'utiliser. Je dois faire un travail qui commence quand Internet est connecté, même si mon application n'est pas au premier plan. Mon travail envoie une requête à un serveur Web pour obtenir des données et je souhaite que mon travail stocke ces données localement dans un fichier XML. J'ai vérifié this tutoriel sur Android-Job bibliothèque, mais il planifie le travail dans la méthode onCreateMainActivity, donc mon application devrait être au premier plan.

Alors, est-il possible d'exécuter un travail en arrière-plan lorsqu'une connexion Internet est disponible sur Android N ou est-il obligatoire d'avoir mon application au premier plan en raison de nouvelles restrictions de services d'arrière-plan?

EDIT

Ceci est mon logcat:

Answer 1

Je ne suis pas sûr de cette bibliothèque que vous avez mentionné, mais vous pouvez enregistrer un récepteur de diffusion dans votre manifeste qui va se déclencher pour « CONNECTIVITY_ACTION Diffusions "ici basé sur l'état de connectivité que vous démarrez le service d'intention qui vous effectuera le travail d'arrière-plan.

Notez que cette solution fonctionnera correctement avant Nougat, mais après cela, vous devrez utiliser Job Scheduler. Selon l'documentation, l'API "fournit un mécanisme robuste pour planifier les opérations réseau lorsque des conditions spécifiées, telles que la connexion à un réseau non mesuré, sont satisfaites. Vous pouvez même utiliser JobScheduler pour réagir aux modifications apportées aux fournisseurs de contenu".

Answer 2

Vous devez créer votre propre emploi avec service, que vous voulez appeler, par exemple MyJob avec MyService:

public class MyJob extends Job { 

    public static final String TAG = "my_job_tag"; 

    @Override 
    @NonNull 
    protected Result onRunJob(Params params) { 
     Intent i = new Intent(getContext(), MyService.class); 
     getContext().startService(i); 
     return Result.SUCCESS; 
    } 

    public static void scheduleJob() { 
     new JobRequest.Builder(MyJob.TAG) 
       .setPeriodic(60_000L) // 1 minute 
       .setRequiredNetworkType(JobRequest.NetworkType.ANY) 
       .setPersisted(true) 
       .setUpdateCurrent(true) 
       .setRequirementsEnforced(true) 
       .build() 
       .schedule(); 
    } 
} 

vous devez également MyJobCreator:

public class MyJobCreator implements JobCreator { 

    @Override 
    public Job create(String tag) { 
     if (MyJob.TAG.equals(tag)) { 
      return new MyJob(); 
     } 

     return null; 
    } 
} 

et init votre travail en Application.onCreate() :

JobManager.create(this).addJobCreator(new MyJobCreator()); 
MyJob.scheduleJob(); 

Answer 3

Oui avec evernote/android-job vous pouvez faire un travail lorsque Internet est disponible et si ce n'est pas le travail sera répété après voici la documentation:

/** * Définir une description du genre de type réseau à vos besoins d'emploi avoir. * Le fait de ne pas appeler cette fonction signifie que le réseau n'est pas nécessaire, car la valeur par défaut est * {@link NetworkType # ANY}. * *
*

Et pour l'utiliser juste faire ceci:

int jobId = new JobRequest.Builder(YOUR_JOB_NAME.TAG) 
      .setPeriodic(TimeUnit.MINUTES.toMillis(15), TimeUnit.MINUTES.toMillis(5)) 
      .setPersisted(true) 
      .setRequiredNetworkType(JobRequest.NetworkType.CONNECTED) 
      .setExtras(extras) 
      .build() 
      .schedule(); 

J'ai utilisé le JOBID pour arrêter ce travail dans le futur. Si vous avez besoin de mon exemple complet, il est mon github où je l'ai utilisé: https://github.com/jdagnogo/Alerte-leboncoin-appart/blob/master/app/src/main/java/com/example/jdagnogo/alertlebonsoinappart/services/jobs/GetLastAppartJob.java
