Managing Many Android Phones for Development

Posted: 04 Oct 2020 09:23 AM PDT

Hi there,

We are working on an app and so far we have 4 different Android phones for development. I guess the number will grow to 10-20 handsets within the next 6-9 months.

My question is how do you or other companies manage all these Android phones from the very beginning once you get a new phone (and you need to sign in with a GMail account), do you do one GMail account per phone or do you use one GMail account for all development phones?

I came across Google's cloud identity and Microsoft's Intune for "Endpoint Protection" so you can manage all these devices and you pay per device but I don't know if that's a good option. Here is what I want to do exactly:

Sign in with one email account
Deploy the same apps on all phones remotely instead of doing it manually on each phone.
Locate all phones (through a dashboard for example) to see which is on/off, where is it each phone located, which network is it connected to, ...
In case one phone is lost or stolen, lock it and then wipe it if I can't have it back.
Other features like disabling the installation of more apps won't be necessary at this stage, but it would be good to have.

I guess the main thing that I'm after would be not creating an account for every phone and having a dashboard to remotely control all the phones.

By the way, we are using Office365

Thanks!

Promotion timing

Posted: 04 Oct 2020 03:36 PM PDT

Hello,

Do you usually wait to promote your apps (e.g. ads, promo giveaways) at specific occasions like Black Friday, Xmas, etc? If yes, do you find it worthy?

Thanks!

Problem with items in recyclerview

Posted: 04 Oct 2020 01:28 PM PDT

Can anyone help me? I'm having this problem with items in horizontal scrolling recyclerview. So what happens is the data for the item in the list loads from firebase but doesn't display in the recyclerview but if i go to any other fragment and come back i can see the item displayed. And the blank state is totally random.

Framework to build map related application (about trails, POI and so on...)

Posted: 04 Oct 2020 12:10 PM PDT

Hi! I want to develop a map app about trails, POI and other map related stuff.

It's tempting to use Flutter or React Native, but I'm worried about flexibility of the frameworks.

What would you choose?

Is the default actionbar obsolete?

Posted: 04 Oct 2020 10:19 AM PDT

Are there any advantages of using the default actionbar instead of going with a custom actionbar which offers much more flexibility?

What is the current consensus about Data Binding in the Android Development community?

Posted: 04 Oct 2020 03:57 AM PDT

So I've inherited a two and a half year old codebase which basically implements DataBinding architecture using MVVM architecture almost exactly as laid out in this Youtube video:

https://www.youtube.com/watch?reload=9&v=TW9dSEgJIa8

It doesn't use Android ViewModel classes or LiveData but instead custom ViewModel classes which extend the Databinding Observable interface and LifeCyclerObserver. The Activities and Fragments then observe the ViewModel which basically then propagates changes to the UI Layer or calls methods in the UI layer (all written in xml) using notifyChange() or notifyPropertyChange() methods.

Now my instinct is to not really like this pattern, as I feel that it makes the code a lot less readable and too abstract, and having all the methods written in the xml layer (and all the recycler view adapters attached in the xml layer) makes the code a lot harder to debug. It also seems to require quite a learning curve for the developer, and if we were to hire some junior developers I would worry that it would take quite a while for them to get used to this way of writing code, which is a time and money overhead for the business.

On the other hand, I do appreciate the beauty of having your UI automatically responding to the state of your model, and making booleans etc. observable cuts down a lot of code and makes it more difficult to introduce logical errors. It also means that activities and fragments are about a third of the size in terms of lines of code (although I'd also argue that although there are less lines of code to write, the mental effort of understanding the observable pattern and ensuring your xml and Viewmodel adheres to the class names automatically generated by the Data Binding library doesn't necessarily make it more efficient)

In short- I'm not sure whether to propose a rewrite of the architecture to make it more readable and understandable for new developers, or whether to propose a partial rewrite to utilise LiveData rather than the Databinding Observable (which seems outdated now), or whether I'm just being ignorant, and not appreciating the advantages and the full beauty of Databinding.

Thoughts?

App developing as open or closed source?

Posted: 04 Oct 2020 12:15 AM PDT

Hello everybody,

I started a new android app project. I will develop an application for my university. I have an own gitlab server and all my projects are there stored. But for this project, a fellow student (I hope it's the right word) give me an advice to take the app from the beginning to GitHub and making the project open source.

I do this never before, so, what would me bring this? What do you thing about the idea?
