    Who has switched from web dev to Android successfully? What's your story?

    Posted: 01 Feb 2018 06:18 AM PST

    I'm currently a web dev (ASP.net) and have been struggling to find an Android position . I have one app on play store and have been getting some interviews. I end up making it to final rounds but end up getting rejected for not having enough experience.

    Has anyone ever gone from web development to Android. What's your story? How many apps (if any) did you have out? What kind if interviews did you do? How many interviews did you do? What kind of obstacles did you face?

    Any insight would be great!

    Google abusing IllegalStateException as always. Here in Google Play Service, and a tad more in core Android.

    App review/rating hub

    Posted: 01 Feb 2018 11:00 AM PST

    I think it would be a good idea to make an app reviwew thread, where we all review each other's apps. If it's a way for each dev on this thread to get 5 genuine reviews, what's the harm right ? No bot, free, organic.

    Here are the rules :

    • Tag the users you reviewed when posting your link

    • Post your link only one time.

    • If you think a user didn't review your app and tagged you, downvote the post.

    Link up !

    RxJava — Schedulers — What, when and how to use it?

    Performance of the layoutinflater

    Posted: 01 Feb 2018 12:24 AM PST

    I'm currently developing a video player app for Android using MVVM, Dagger2, RxJava2, DataBinding.

    For this app I am using my custom implementation of DraggablePanel: https://github.com/pedrovgs/DraggablePanel

    That is, I have a Player window that stays on top and you can drag to minimize while still operating with the rest of the app, in a similar fashion as youtube does.

    This means the app has to consist of a single activity that keeps this view on the root of all views and all navigation happens with fragments. Now if you check the implementation of this library you'll see it accepts two fragments, one on top (the drag view), one on the bottom (the bottom part that goes transparent when dragging). I modified this so that on top theres always a video player, and the bottom fragment is flexible. Depending on the video you click on, you can get a different view (either a recycler view with a playlist, or a recyclerview with the highlight moments of the current video).

    This means every time you click on a video I need to build a fragment and attach it to this view. I did this and it works okay, except for the maximize animation being a bit too jerky cause of the inflating process.

    In order to make sure it was the inflation that was causing the jerkiness, I removed all processing from the fragments except for the view rendering itself, I also checked with GPU profiling and the bars spiking were those of rendering & inflating. I also tried making the bottom fragment be just a textview, and in that case the animation is smooth. I profiled the real layouts to simplify them & remove nested layouts, now I'm mostly using ConstraintLayouts all over the place (which are supposed to be the most performant).

    I tried adding both kinds of fragments to the manager, then showing & hiding when needed, but this brings its own set of problems when dealing with restoring state.

    I have trouble believing inflating is so slow. In parallel an analogous iOS app is under dev and this works fine for that platform.

    Also tried with the example posted here: https://www.reddit.com/r/androiddev/comments/7rfwwx/the_best_architected_android_apps_i_have_come/

    and when you switch tabs on the viewpager, you also get some jerkiness there.

    Is the LayoutInflater really that slow? How can this be improved? Maybe I am missing something? How do apps like Youtube handle this? I saw they do something similar to what I want to achieve.

    Would someone mind critiquing my store listing?

    Posted: 01 Feb 2018 03:26 PM PST

    Although retention for this first week is good, when I run google ads I can't seem to get good conversion rates. I get about 1 conversion for 1500 impressions, while with previous softwares I was getting almost 1 per 250 impressions.

    Somethings obviously wrong with the listing I suppose.

    https://play.google.com/store/apps/details?id=com.ericz.stockvote

    here it is. It's financial software, so It's hard to theme up really, but if anyone knows how I can make this more appealing I would appreciate to know.

    Thanks!

    Apps supporting Storage Access Framework

    Posted: 01 Feb 2018 04:02 AM PST

    I am currently implementing a DocumentsProvider in my app, using the Storage Access Framework. For those who don't know, this lets client apps select files/folders with this standard activity. However, I'm having real trouble finding any apps that support the Storage Access Framework. Duckduckgo/Google weren't really helpful.

    Here are some apps that support it:

    • Firefox (for file uploads)

    • Files (file manager in Lineageos 14.1)

    Other apps that (surprisingly) don't seem to support it:

    • VLC

    • Google Photos

    • Stock Gallery on Android 6/7.1

    • any music player that I tried, including Google Play music

    Do you know any apps that support this? I'm specifically looking for image/video viewers, music players and file managers. Bonus points for any open source apps.

    Good place for App templates

    Posted: 01 Feb 2018 11:48 AM PST

    I'm looking for an app template for a food ordering kiosk\POS\kitchen viewing back-end system. Perhaps a combination of one of those, and I can fill in the blanks later. Essentially, I'm looking for good bare-bones that I can work with... either open source, or open-source with a license, so that I can customize the way I want. I've been looking at some HTML5 options, but I think a full on native app would be best for this, with a php\mySQL back end.

    Thoughts? Links?

    Thanks!
