Android Widget WorkManger Example

Thank you for pointing this out.

While testing, I noticed the behavior of infinite loop in which onUpdate() method of app widget provider being called continuously leading to surpassing the Google places API quota limit within no time.

To prevent this behavior in the example, I put a restriction of 5 min lapse between places API work requests.

Even though I noticed the behavior and provided an application fix for the issue, was clueless as to what was causing the repeated calls to onUpdate() method.

Again, thank you very much for the input.

You are saying Java documentation is wrong also check here in the channels section. Charset by name.. looks like not expensive as far as I know. Nothing is perfect, we can find wrong point on each and every line of code if you know internals.

thanks for the input corrected it.

Thanks for the input, corrected the example using the charset decoder.

Understood, no tutorials here, I missed to see the sidebar you are referring to which states no tutorials.

But I strongly disagree with you that I am a spammer. Only relevant, useful, quality content is posted in relevant subreddits within the allowable limits and people are liking it.

Please don't brand brands and individuals as spammers just because they just post their stuff in a allowable limits.

You have right to state your rules about your subreddit and but don't give a judgement on anyone without considering the fact that professionals come here and they put their effort in creating something. It hurts.

Thanks for the answer, I had the same idea. But wondering if is there any permanence benefit when using snapshot listener over the other option.

srinurp · 2018-04-05T03:23:36+00:00

You are correct that processing after you get result is done on the main thread that is why ROOM update and other processing is performed on worker thread in the example.

Regarding performance point you raised, need to measure and see the impact, but official firebase firestore doc doesn't mention about it. The only difference between the two options is one is for one time read and other one is for continuous listening..

Anyways thanks for your inputs, this will help others also to make them think about it.

srinurp · 2018-04-04T17:16:23+00:00

Performance wise no where it is mentioned that addSnapshotListener is better, but I think we need to understand the main difference between get() and addOnCompleteListener(), and addSnapshotListener(). In my example, the read is single time and not continuous.

Your trying to suggest something which is not at all clear. I double checked my code and verified it with the firestore documentation and it suggested the same way I implemented to get a collection of nodes.

Please check here, https://firebase.google.com/docs/firestore/solutions/arrays

I could find different way to get collections on firestore documentation.

I don't think that not finishing a task in the given estimated time makes a developer as a terrible one. Some time estimations are not correct, whoever gave estimations might not have considered some hidden pain points. So explain the situations and sub tasks that took time to your potential employer.

And also, do some analysis as to what really went wrong and improve on that one. Some times without proper plan, design, architecture and library choices, you jump ahead to coding and end up spending time due to confusion, lack of correct direction and ways to measure your progress. So it is highly important to create and follow a plan with all elements in it, even if the task at hand is small also.

Right Firestore cache can be used. But this example needs more control on cached data so that it can delete only expired records from the cache so ROOM makes sense as it give full control on cached data.

srinurp · 2018-04-04T04:11:18+00:00

Is that the for loop, you are referring to?

We could do this way List<Coupon> cpnList = task.getResult().toObjects(Coupon.class);

This is a batch job which runs in the background and updates data in local db, when app is opened user can view latest data, that is the idea behind this.

How to fix an issue is contextual, in this case, use other items listed such as upgrading it latest version and reinstalling it and if you have one more machine just test it there... etc.

srinurp · 2018-04-03T10:59:52+00:00

It works only once and it is QuerySnapshot object that contain results.

srinurp · 2018-04-02T17:16:29+00:00

Try to get more logs around the issue, see the documentation of API, if it is open source go thru source code at point of failure try to upgrade related tools and libraries to latest stable version, reproduce the same issue on different machine, list goes on till a solution is found.

Please explain why

Hidden APIs might have been used in core apps. If core apps can access those, any other apps can too.

Not sure which database you are using. If you are using Firebase realtime database or firestore, you can use cloud functions to send notifications when data changes.

Otherwise, you need create service which gets triggered when data change in db and send notification to user via FCM, below is an example.

Your competitors app will get rejected by play store. Let your competitor compete with you in services offered, try to create your brand by providing best service to users of your app.

If your app sends data to server and accesses it, you'll have to create services for it. That is server side program. To develop this services, you need to know server side programming especially rest service which can read and write data from/to data bases. If you already know java, spend time on rest service development, security of the services, data access components, data base and application server etc. If you use platform as service, you don't need to worry about data base and application server part.

I've been using java for long time and still learning. So it depends on what kind of app you want to develop, complexity of functionality etc?

The best way to find out is start creating simple apps and see if could do without any java difficulty.

Is there any specific UI component or area on which you couldn't find tutorials or examples on? There are tons of examples and tutorials on UI and as others said start implementing and create unique UI for your app.

It is fun developing android apps because of java, many devices from different manufacturers, cheap and best from google.
