Android Dev - Weekly Who's Hiring Thread - January 18, 2021

I have a layout that have ScrollView with some content. On the bottom of the screen (not below the scrollView), I have WebView with some content loaded. The webView is always visible on screen and it is in front of the scrollView.

What I want to achieve is this:

As the scrollView scrolls down, the webView content should scroll down too. Same thing with scrolling up, the webView content should scroll up.

The webView, itself, should not be scrollable.

On Medium you can find my article on measurement inaccuracies in Profiler:

This time instead of only writing a post I also created for you a video on the same topic 🎥. So if you prefer to listen to me talking about measurement inaccuracies in Profiler, I'll be thrilled if you check it out, but if you prefer reading, this post contains the same content as the video.

Examples of non-phone devices based on AOSP?

Posted: 17 Jan 2021 06:58 PM PST

I'm giving a workshop to college students about being an Android dev. I want to give some examples of AOSP based devices other than phones, to point out that Android knowledge can lead to more than mobile app development. Tonal, Portal, and the Kindle are some examples I thought of. Probably most smart TVs? Any concrete examples are appreciated!

New app with status "In review"

Posted: 18 Jan 2021 02:10 AM PST

Hey there. I am making my first Android App and I created a Google Developer Account to upload it to Google Play. I went with an open testing release since my app is functional but not in the form I want it to be when it goes "public".

I did that 3-4 days ago, and app has a status of "In review" in Google Play Console. Is that timing normal? How long does it take normally for a new app to be reviewed? Also does it matter that it's an open testing release and not a full blown public release?

(I don't have any ads in it and I have selected all ages and countries, followed by the policy and terms links that are required for that.)

Thank you!

Suggestions to learn new technology in 2021

Posted: 17 Jan 2021 01:27 PM PST

Hey folks,

I have around 3 yrs of experience in Android development and have learned almost everything latest in Modern Android Development.

I am not planning a job change and I don't have much responsibilities at my current job. So, I have a lot of free time right now and I don't want to waste it.

Should I learn Backend/iOS or any new programming language/framework which might help me further in my career? Also anything on latest trends such as AI/ML or something advanced in Android?

I am pretty confused here as what would be beneficial for my career. Any help would be great.

Scala 2.13 on Android (an update with a slightly more complex example)

Posted: 17 Jan 2021 10:26 AM PST

Hi all,

Some time ago I wrote how I managed to put together a simple example of how we can write Scala 2.13 on Android with help of GraalVM and Gluon Mobile. (the standard way of simply using Scala in Android projects forces us to use Scala 2.11 and a bunch of hacks on top of that). I decided to reorganize the repo and write more examples, each one testing one of the main features and Android app should have. This one is about JavaFX widgets and it is based on "Fifty States" from Gluon Mobile samples. It's a scrollable list of European Union countries and Scotland. The flags of countries are being downloaded from Wikipedia in the run time and stored in a file cache.

I also added some notes about problems I faced, how you can write this from scratch, and what next I want to do. Here's the link to GitHub: https://github.com/makingthematrix/scalaonandroid/wiki/European-Union-(and-Scotland)-example-example)

Thanks!

Caching strategy for paginated search results (Paging 3)

Posted: 17 Jan 2021 05:17 PM PST

I'm using Paging 3 with RemoteMediator to search news articles from newsapi.org and paginate the results while also caching them for offline use (in Room). The API is paginated by passing a page number starting from 1. I'm unsure about the correct approach to cache the results. I see 2 options:

I could store each query and each article in their own table, create a many-to-many relationship between them in a 3rd table that also contains the next and previous paging key for each article/query combination. Like this:

 | searchQuery | articleUrl | prevkey | prevKey 1 | food | blah.org/a | 1 | 3 2 | dogs | blah.org/a | 4 | 6 3 | dogs | blah.org/b | 4 | 6 4 | money | blub.org/x | 1 | 3 5 | health | blah.org/a | 2 | 4

As you can see, each URL can exist in multiple search queries and each entry contains the corresponding paging keys. When I then run an old search I fetch the results for that exact query from the database (if it exists yet). But this setup is kinda complex.

The other option would be to just let Room query the search keyword in the same fields (i.e. title and description of an article). This would be easier to set up but I am not sure if this will lead to any bugs if the search query/order from the API and DB are not perfectly similar.
