Android JobScheduler Won't Stop With JobFinished(params, False)


Answer :

You have specified that a job is run periodically (every 60 seconds), so every 60~ seconds a new job is created and executed. jobFinished() is specific to a job, and simply indicates that it is done executing. You haven't cancelled anything.

Your (currently) accepted answer works for cancelling your scheduled job, but if all you want is a job that executes within 60 seconds and then stops, you should ommit setPeriodic() and use setOverrideDeadline(60000) instead. The job will run within 60 seconds and no more will be scheduled after it.


Well I figured it out if anyone else has this problem.

jobFinished() won't stop the periodic time you set from continuing. It just tells the job that you are finished, to release the wakelock, so Android doesn't have to kill the job off forcefully.

What I had to do was recreate the jobScheduler in my service and call cancelAll(). You could also apparently call cancel(job_id).

jobScheduler = (JobScheduler)this.getSystemService(Context.JOB_SCHEDULER_SERVICE ); jobScheduler.cancelAll();

I was using multiple JobService, and to stop one specific Job, I used the id of job to cancel the job.

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP) public static void stopMyJob(Context context, int jobId) {     JobScheduler scheduler = (JobScheduler) context.getSystemService(JOB_SCHEDULER_SERVICE);     scheduler.cancel(jobId); }

First I checked if the current job is active by or not, using the following function

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP) public static boolean isJobActive(Context context, int jobId) {     JobScheduler scheduler = (JobScheduler) context.getSystemService(JOB_SCHEDULER_SERVICE);     boolean hasBeenScheduled = false;     for (JobInfo jobInfo : scheduler.getAllPendingJobs()) {         if (jobInfo.getId() == jobId) {             hasBeenScheduled = true;             break;         }     }     return hasBeenScheduled; }

While starting the job, I have the id passed to jobInfo as:

JobInfo jobInfo = new JobInfo.Builder(jobId, componentName);

The same jobid I used to stop the job by calling my function stopMyJob(context, jobID).

In most of cases, it's important to stop the current job and start the job again from beginning, if it's already running, for thais I used my both functions mentioned above as:

if (isJobActive(activity, ANNOUNCEMENT_JOB_ID)) {     Log.d(TAG, "Job will cancel as already exist");     stopMessagingJob(activity, ANNOUNCEMENT_JOB_ID);     }     startMyJob(activity, ANNOUNCEMENT_JOB_ID);

My startMyJob(context, jobId) looks like:

    private static void startMyJob(final Context context, final int jobId) {             ComponentName componentName = new ComponentName(context, MyJobService.class);                 JobInfo jobInfo = new JobInfo.Builder(jobId, componentName)                         .setPersisted(true).setPeriodic(TWENTY_MINUTES).build();                 JobScheduler scheduler = (JobScheduler) context.getSystemService(JOB_SCHEDULER_SERVICE);                 int resultCode = scheduler.schedule(jobInfo);                 if (JobScheduler.RESULT_SUCCESS != resultCode) {                  Log.d(TAG, "Job failed to start");                 } }

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
