Android-job: JobStatus.getUid()' on a null object reference

[tobiasschuerg]

Not sure if actually an issue with this lib or maybe gcm.

Cant't reproduce but seems to happen after JobManager.instance().cancelAllForTag.
Up to now only appeared three times (2x Samsung 5.0, 1x Huawai 6.0) within the last week (having a few thousand active users per day).

I haven't seen this before. Looks more like an issue with the JobScheduler and you could file a ticket at AOSP. I don't think we can do anything here.

[tobiasschuerg]

Might be related to this one: JobScheduler: Calling jobFinished from onStartJob makes the app crash randomly

[vRallev]

I'm not sure. The library calls jobFinished() asynchronously on a background thread. That's different than what the bug report states.

[vRallev]

Maybe it was already fixed? https://code.google.com/p/android/issues/detail?id=170814 Do you use the JobScheduler at other places?

[tobiasschuerg]

I don't think so as I only added this library about ten days ago, already using the latest available version.

[vRallev]

It looks like I can't do anything. This is a platform bug and there is no way to catch it. Do you have an idea?

[vRallev]

Closing because of inactivity

[NiaNingXue]

I have the same issues

[hkllzh]

I have the same issues

[vRallev]

That's a bug in the Android platform. You better file a bug here: https://code.google.com/p/android/issues/list I'm also not aware of any workaround :(

[varunasingh]

Is the explaination mentioned here relevant ? : https://github.com/yigit/android-priority-jobqueue/issues/157#issuecomment-222320643

[vRallev]

No, that's a completely different project.

[varunasingh]

different project, but same android issue and bug. I'm wondering if their workaround (mentioned in the comment) can be applied as a workaround here.

[yeduRaghav]

Has anyone found a resolution for this ?

I am also still getting this crash with com.evernote:android-job:1.2.6 and Android 6

[chuks]

Has anyone found a work around for this? It looks like Google is not fixing this, as several people have reported this bug, but they've closed it.

[ghost]

I am too facing the same issue. Is it fixed ?

[Codyfjm]

I am facing this project nearly, How to fix it

[ghost]

Handling that NPE was only option that I found. So surround it with try-catch.

[VladislavNikolaev]

Handling that NPE was only option that I found. So surround it with try-catch.

How did you syrround it with try-catch, could you show your implementation, please?

[ghost]

I did it as follows.

@Override
    public boolean onStartJob(JobParameters jobParameters) {
        // TODO Add your task

        // Should be protected to avoid crash in a device where call to jobId() results in NPE. Seems platform error
        try {
            jobFinished(jobParameters, true);
        } catch (NullPointerException ignored) {
        }
}

Same here

[BryanSharp]

I did it as follows.

@Override
    public boolean onStartJob(JobParameters jobParameters) {
        // TODO Add your task

        // Should be protected to avoid crash in a device where call to jobId() results in NPE. Seems platform error
        try {
            jobFinished(jobParameters, true);
        } catch (NullPointerException ignored) {
        }
}

did this work for you?

No. It did not.

I'm also facing the same issue on Android version 5 and 6 only. Did anyone find any sound solution?
