Weekly Questions Thread - December 05, 2016

Posted: 05 Dec 2016 04:13 AM PST

This thread is for simple questions that don't warrant their own thread (although we suggest checking the sidebar, the wiki, or Stack Overflow before posting). Examples of questions:

  • How do I pass data between my Activities?
  • Does anyone have a link to the source for the AOSP messaging app?
  • Is it possible to programmatically change the color of the status bar without targeting API 21?

Important: Downvotes are strongly discouraged in this thread. Sorting by new is strongly encouraged.

Large code snippets don't read well on reddit and take up a lot of space, so please don't paste them in your comments. Consider linking Gists instead.

Have a question about the subreddit or otherwise for /r/androiddev mods? We welcome your mod mail!

Also, please don't link to Play Store pages or ask for feedback on this thread. Save those for the App Feedback threads we host on Saturdays.

Did widgets die out?

Posted: 05 Dec 2016 01:00 PM PST

I've been thinking of adding an accompanying widget to my app, but it seems that widgets are not as hot as they were before, currently if I check my list of available widgets for all my installed apps, it is a very humble list, and usually are just icons that lead to the app, which is confusing as I find widgets can be very powerful tools if done right, is there a reason for this? Did devs face issues when trying to write a "good" widget?

Revealing personal information when releasing an app?

Posted: 05 Dec 2016 07:32 AM PST

Is it absolutely necessary to have your address public when you release your app?

I want to release my work, but I hesitate because of the security concerns.

With Async data fetching, how do you avoid flicker?

Posted: 05 Dec 2016 04:39 AM PST

We all know that it's bad to do expensive stuff such as database access on the main thread. We all know that RxJava and any one of the cool MVP libraries make it easy to fetch data asynchronously before passing it to your Activity/Fragment/View for display.

What do you do about that short delay after your View is shown, but before the data has arrived? No matter how fast the data access is, the very fact that it's asynchronous means that there is an annoying flicker.

Possible solutions:

  • To hell with it. Just grab the data on the main thread.
  • Make sure the view looks good with no data, to make the flicker less jarring.
  • Use slow fades and transitions, so the data is fetched before the view is fully visible.
  • Fire up the presenter before showing the view, so the data is already there. (Do any of the current MVP libraries support this?)

Any other options?

Apache 2 License Question

Posted: 05 Dec 2016 07:09 PM PST

I'm creating a library for which I intend to apply the apache 2 license to.

  • Do I need to add the header to every source file to comply with the license?

  • I copy/pasted then heavily modified a few files from another apache 2 licensed library. How do I ensure I respect the original authors?

I understand the usual this does not constitute legal advice, etc.

How to get 1 star reviewers to try the app again?

Posted: 05 Dec 2016 11:56 AM PST

Unfortunately just a couple of days after we started advertising for our app, we had a fluke Heroku error that prevented new users from signing up for our app (I believe the database was full or something). During that time we had a sizable number of users download and try to use the app, then rate it one star because they couldn't sign up. Is there a way to get these users to try the app again beyond replying to their Play Store reviews?

What are some good Java servlet hosting options for the backend of your app?

Posted: 05 Dec 2016 11:23 AM PST

So I'm currently using Google App Engine, mostly because it's so convenient to deploy from Android Studio. But it just seems like it's very expensive even now when I'm doing closed Alpha testing, and it's not very suitable for work with Firebase (issues with the background thread shutting down etc.), so I'm looking for alternatives.

Does anyone have experience with some cheaper (but still easy to use) options for hosting ~15 Java Servlets? My database and a lot of the backend functionality is in Firebase.

Prolific open source devs, what advice do you have for open-source beginners?

Posted: 05 Dec 2016 04:54 AM PST

I've been working on android since 4+ without ever contributing to open source. I'm guessing neither have most developers. I want to change that. This recent post got me started.

What are some things that devs looking to start contributing should know about? Common bugs and gotchas? General best practices? Where to find ideas?

Also, what is the difference between: Maven, Bintray, Jcenter, Jitpack? Which one do I want?

I want to make an app that acts like a live feed for my family so they feel more connected/up to date whilst i'm away.

Posted: 05 Dec 2016 02:54 PM PST

Hi guys,

I study computer science and i know how to program in java and c, but have never made an app before. My family uses android, ios and windowsphone.

My app idea is that if they open the app all they see is a message/text by me with what im currently doing and what i have done before (timestamps) and i want to update this feed via pc (or if its easier with my windowsphone).

I would like them to be able to switch on/off a notificator (if that's a word) so when i update my status they get a notification in their top bar.

I don't know if a have to do 3 seperate apps for each os, but if that's the easiest/only way to do it it would be fine with me.

I would really happy if someone could send me some links or tutorials so i can make this app as a christmas present.

Thank you! :)

Where do you start when developing MVP projects with tests? Presenter -> Test Presenter -> Interactor -> Test Rest calls -> View -> Test View?

Posted: 05 Dec 2016 08:50 AM PST

Once I read about that flow:

Presenter -> Test Presenter -> Interactor -> Test Rest calls -> View -> Test View

How to increase productivity?

I personally do as follow:

  • 1) Layout
  • 2) Map components to activity
  • 3) Presenter + Interface.
  • 4) Implement Interface methods in Activity.
  • 5) Create button events calling presenter public methods
  • 6) Implement presenter public methods
  • 7) Create Presenter Test
  • 8) Interactor
  • 9) Mock and test calls

What are you tips to get visibility ?

Posted: 05 Dec 2016 08:41 AM PST

Hello everyone, I'm starting doing dev on my free time and really enjoying it, I have a long list of projects ideas i'm looking forward to work on. Yet on my curents apps the numbers are not raising at all, i have like twenty download on one, and exactly three on an other. I get it that i wasnt going to get thousands and thousands but maibe wasnt expecting that literally no one stumble upon my apps. Whithout talking about paid ads, what are the ways for my apps to reach their potential users ?

TL;DR: How to get visibility ?

Testing websites on multiple Android versions

Posted: 05 Dec 2016 12:56 PM PST

Hi, I'm developing a small website and I noticed that it wasn't working as expected on older versions of Android (i.e. 4.1). Is there a way I can test, ideally visually, on many Android versions at once? Thanks

I wanna write a blog. Part 2.

Posted: 05 Dec 2016 12:41 PM PST

The previous post https://www.reddit.com/r/androiddev/comments/5gba4b/i_wanna_write_a_blog/?st=iwcjfm0e&sh=fced2d48

In this post number 2 http://slaverygames.somee.com/Views/Post2.html I wrote about my first app that I published to Google play. About that how I was searching for an idea for an app. How I promoted an application. How I was playing in SEO (Search Engine Optimization). How many I earned for two months. That was fail but still gives experience :)

I created a new thread to separate comments between blog posts. I don't have comments on my site so if you have any comments write it here.
