WorkManager Codelab

This repository contains the code for the WorkManager Codelab:

Java version

The Java version of this codelab is available under the Java branch of this repository.

Introduction

At I/O 2018 Google announced Android Jetpack, a collection of libraries, tools and architectural guidance to accelerate and simplify the development of great Android apps. One of those libraries is the WorkManager library. The WorkManager library provides a unified API for deferrable one-off or recurring background tasks that need guaranteed execution. You can learn more by reading the WorkManager Guide, the WorkManager Reference or doing the WorkManager Codelab.

Pre-requisites

• Android Studio 3.6 or later and you know how to use it.

• Make sure Android Studio is updated, as well as your SDK and Gradle. Otherwise, you may have to wait for a while until all the updates are done.

• A device or emulator that runs API level 16+

You need to be solidly familiar with the Kotlin programming language, object-oriented design concepts, and Android Development Fundamentals. In particular:

• Basic layouts, widgets and View Bindings
• Some familiarity with Uris and File I/O
• Familiarity with LiveData and ViewModel

Getting Started

1. Install Android Studio, if you don't already have it.
2. Download the sample.
3. Import the sample into Android Studio.
4. Build and run the sample.

Crash "Apps may not schedule more than 100 distinct jobs"

Hi, I am testing an app since a few days I have been scheduling tasks with workmanager everyday. today I added a new one and I got a crash with the following log (all my tasks of the previous days were already finished).
Now the app can not start anymore, unless I delete all the app's data.

1-Does this mean I had 100 tasks during the last few days?
2-Or does this mean my last task was accidentally launched >100 times?
if 1, why are we limited to 100 tasks

Is it a known issue? any help would be appreciated. thanks

Unit test?

How do we write unit test for WorkManager class?

7. Ensure Unique Work - Wrong URL for REPLACE, KEEP and APPEND docs

There's a typo in the URL the user is sent to when clicking on either REPLACE, KEEP or APPEND.

Currently:
http://d.android.com/eference/androidx/work/ExistingWorkPolicy#replace
Should be:

Not Working in Oppo Devices, when force quit the application

The task is still guaranteed to run, even if your app is force-quit or the device is rebooted. This statement stands false in case of oppo

Is WorkManager ready for production?

Hi (-:
WorkManager looks like a great API that can fit in many use cases. Especially running a work even after an app is closed/restarted.
Is WorkManager ready for use in production apps, and if not, can we get a rough estimation?

Crash when language is Arabic

While running the pre-launch report for our app we ran into a crash which looks to be caused by WorkManager.

I'm guessing the problem is caused by private static String getPruneSQL() using the default locale of the device instead of English.

No tests

There is no tests for this codelab so it seems unfinished. It would be great to add the examples of tests for workers, like in other AAC codelabs.

Notification throwing a RemoteServiceException

Setting a vector as the small notification icon is throwing RemoteServiceException. I ended up using a png drawable, now it works. I know they're other solution but this is the fastest.

SmallIcon caused error

NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_launcher_foreground) --> it will cause error, I change to ic_launcher_background and it works. ic_launcher_foreground is only for api 24, I ran on 23

I am the sprout

Can you add a repeat request column

Didn't find WorkSpec for id **********

When i call the one time request again and again, I get Didn't find WorkSpec for id message for the completed requests.

Lets say if i call onetimerequest and its id is 475c853c-09b8-4d38-9074-0b373f60c1b7. It gets completed and then if i call the method again it creates new onetime request with id 564a7af4-f871-48a2-9737-ab000c4098e7 and enqueue it but give me error message Didn't find WorkSpec for id 475c853c-09b8-4d38-9074-0b373f60c1b7

Does this mean i shouldn't be creating new instance of OneTimeWorkRequest every time but only one instance throughout the app for that specific worker class.

public static void runOneTimeRequest() {
   Constraints mConstraints = new Constraints.Builder()
    .setRequiredNetworkType(NetworkType.CONNECTED)
    .build();
   OneTimeWorkRequest oneTimeWorkRequest = new OneTimeWorkRequest.Builder(OneTimeWorker.class)
    .setConstraints(mConstraints)
    .addTag("one_time")
    .build();
   WorkManager.getInstance().beginUniqueWork(TAG_ONETIME_REQUEST, ExistingWorkPolicy.KEEP, oneTimeWorkRequest)
    .enqueue();

Stable version

At the moment the library is at version 1.0.0-alpha08, I would like to use it in an app on the production channel but I do not think it's a good idea as long as it remains in the apha version.
Is it possible to know when it will be released in a stable version?
There is a roadmap?

PeriodicWorkRequest not working properly in API 23

I am working on an application in which I have to increase day counter by 1 after completion of 24 hours.
My PeriodicWorkRequest code is as follow:

build.gradle (app):

ext {
    workVersion = "1.0.0-alpha02"
}
dependencies {
    ...
    // WorkManager for background service
    implementation "android.arch.work:work-runtime:$workVersion"
    // optional - Firebase JobDispatcher support
    implementation "android.arch.work:work-firebase:$workVersion"
    ...
}

Below code is in ViewModel Class which extends AndroidViewModel:

PeriodicWorkRequest.Builder dayWorkBuilder =
                new PeriodicWorkRequest.Builder(DayIncrementWorker.class, 24, TimeUnit.HOURS, 5,
                        TimeUnit.MINUTES);
      
        // Add Tag to workBuilder
        dayWorkBuilder.addTag(AppConstants.DAY_INCREMENT_WORK_NAME);
        // Create the actual work object:
        PeriodicWorkRequest dayWork = dayWorkBuilder.build();
        // Then enqueue the recurring task:
        mWorkManager.enqueue(dayWork);

I have noticed two issues when I get message "Flex duration is currently not supported before API 24. Ignoring." in Logcat.

Issue1: In API 23 devices as well as emulator with API 23, Worker executes two times when it schedules PeriodicWorkRequest and it increase my day counter twice. At that time I got bellow log message in Logcat.

06-19 11:26:09.606 23494-23605/com.packagename D/SystemJobInfoConverter: Flex duration is currently not supported before API 24. Ignoring.

Issue2: In API 23 devices as well as emulator with API 23, Worker executes randomly. Though I set PeriodicWorkRequest for 24 hour, when I close and kill app from the background and launch again, it increase my counter.
I was facing same issue(b/79660657) in version '1.0.0-alpha01' in 'Samsung (Galaxy On7 Pro Model SM-G600FY, Android 6.0.1, API 23)' device but after updating to version '1.0.0-alpha02' it get resolved in that 'Samsung' device but it still exist in 'OnePlus2 (Model ONE A2003, Android 6.0.1, API 23)' device. The only difference is that in version '1.0.0-alpha01' it was updating value everytime I close app and launch app again and in '1.0.0-alpha02' it is happening randomly not everytime I close and launch app again. Don't know why!

Above mentioned Issue1 still exists in 'Samsung' Device. It increase day counter twice very first time when job is schedule via Worker.

I have Noticed one thing that these two issues exist only in API 23 devices where I got 'Flex duration is currently not supported before API 24. Ignoring.' message in Logcat. Except API 23, it works fine. I have tested in LG-G2 (Model LG-D800, Android 5.0.2, API 21) as well as different emulators it is working fine.

java.lang.NullPointerException

 Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void androidx.work.WorkManager.enqueue(androidx.work.WorkRequest[])' on a null object reference

// Create a Constraints that defines when the task should run if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) { PeriodicWorkRequest.Builder photoCheckBuilder = new PeriodicWorkRequest.Builder(AppInitManager.class, 15, TimeUnit.MINUTES); PeriodicWorkRequest photoCheckWork = photoCheckBuilder.build(); WorkManager.getInstance().enqueue(photoCheckWork); }

Sending Uri.toString() in Bundle.

This is dangerous way to place an Uri to a Bundle by means of toString() if it contains non-latin characters:

private Data createInputDataForUri() {
    Data.Builder builder = new Data.Builder();
    if (mImageUri != null) {
        builder.putString(KEY_IMAGE_URI, mImageUri.toString());
    }
    return builder.build();
}

It should be changed to:

private Data createInputDataForUri() {
    Data.Builder builder = new Data.Builder();
    if (mImageUri != null) {
        builder.putParcelable(KEY_IMAGE_URI, mImageUri);
    }
    return builder.build();
}

I suppose. And correspondent getParcelable(KEY_IMAGE_URI) on the other side.

Immediate work will not run if another periodic work can run during this period

I have this periodic work scheduled like this:

val expireNotificationWork = PeriodicWorkRequestBuilder<ShoppingListNotificationWorker>(1, TimeUnit.DAYS) // This will default to flex 1 day
                    .addTag(TAG_1)
                    .build()

            WorkManager.getInstance()?.enqueueUniquePeriodicWork(
                    jobName,
                    ExistingPeriodicWorkPolicy.REPLACE,
                    expireNotificationWork)

And an immediate work enqueued like this

val connectedConstraints = Constraints.Builder()
                    .setRequiredNetworkType(NetworkType.CONNECTED)
                    .build()

            val immediateWork = OneTimeWorkRequestBuilder<UpdateGeofencesWorker>()
                    .setBackoffCriteria(BackoffPolicy.EXPONENTIAL, 2, TimeUnit.SECONDS)
                    .setConstraints(connectedConstraints)
                    .addTag(ONETIME_TAG)
                    .build()

WorkManager.getInstance()?.enqueue(immediateWork)

Every time I enqueue the immediate work only the periodic work will run and not any one time work.
So the periodic work will run multiple times per day but the one time work never.

Add the intent data type

Intent actionView = new Intent(Intent.ACTION_VIEW, uri);
actionView.setDataAndType(uri,"image/*"); <-- add this will make the function works!

Unable to recreate the unique work after canceling the previous in Android O

Reproduce :

1. Run the final app
2. Click Cancel Button immediately (within 2 or 3 seconds)
3. Click Go Button and it would be endless loop.
   in the log : 07-04 19:44:26.243 30225-30289/com.example.background E/WorkerWrapper: Status for 70a1791e-e62c-4d5a-90a0-8f109bc5dcc6 is BLOCKED; not doing any work

It is only happens in Android O. When I try in Android M and Android N it works smoothly.

Suggestion : it should recreate the unique which is the ExistingWorkPolicyStrategy is REPLACED

CodeLabs Note : The WorkManager documentation link is not correct

Hi,

In the note, the link to the WorkManager documentation is the one for AlarmManager.

The correct link is : https://developer.android.com/reference/androidx/work/WorkManager

Best regards.

WorkManager create every time new thread?

I am calling this code every 5 seconds

OneTimeWorkRequest  checkConn =
                new OneTimeWorkRequest
                        .Builder(ConnectionHelper.class)
                        .build();

WorkManager.getInstance().enqueue(checkConn);

And i see i the profiler that the number of thread increase every 5 seconds, does it create new thread? it is not run the task on the same thread?

Emulator: Nexus 5, API 23

android.app.RemoteServiceException: Bad notification posted from package com.xxx.xxx: Couldn't create icon: StatusBarIcon(pkg=com.example.background=0 id=0x7f020082 level=0 visible=true num=0)

If we use png drawable like android.R.drawable.ic_menu_add is working

Check WorkerUtils.java line 83 ".setSmallIcon(R.drawable.ic_launcher_foreground)"

Need I call WorkManager.initialize in My Application onCreate?

and some user occur the SQLException.
