    I'm getting sick of third party APK App Stores and piracy uploads of my app. What could I do to remove them? Or should I care at all?

    Posted: 02 Apr 2019 07:27 AM PDT

    Hi,

    ​

    I've been publicated my app 2 months ago to Google Play Store.

    I had some downloads and reviews and even some revenue, the things going well, I update the app very often, it is a wonderful journey, everything is just fine,

    ​

    but:

    ​

    When I google my app I see a lot of random App stores where my app is uploaded. I believe these are script automated stores which hunts down all the apps from Google Play and uploads them there.

    This is bothers me for some reasons:

    ​

    • Every time a user downloads my app from a random app store I lose a potential download from Google Play Store, he or she could download it from the original store too, boosting my download statistics and ASO ranking.
    • These stores almost always lacks the up to date app version, lacks the up to date screenshots and the up to date description.
    • Some users write feedbacks to these random stores and not to Google Play Store, and I cannot/don't want to browse 5-10 random stores for reviews.

    ​

    question:

    ​

    Is this bad for my app? Or should I ignore it?

    As an indie dev I would like to accumulate all the downloads to Google Play Store.

    Thanks in advance,Adam

    View about MvRx for Android is free this week

    Posted: 02 Apr 2019 06:05 AM PDT

    If you like the architecture videos on Caster, there is a new one from Gabriel Peal about MvRx, which looks good. I like to watch these videos - is a good way to level up and stay current (especially the architecture ones).

    https://caster.io/courses/android-mvrx-fundamentals

    MvRx is an Android architecture library built on top of Jetpack that is practical, fun, easy to learn, yet powerful enough to scale to large apps.

    MvRx is simple to learn and integrate into any app no matter how big or old it is. MvRx provides a common structure for you and your team to write consistent code. MvRx has numerous features that reduce boilerplate and eliminate many error-prone areas of development such as managing the Android lifecycle or error states for asynchronous actions. In this course, you will learn how much MvRx simplifies Android development for every use case, simple or complex.

    We will:

    Learn how to integrated MvRx into an existing app Learn how Jetpack's ViewModel architecture solves key lifecycle and data challenges Learn how to model complex state with simple immutable data classes Learn how to integrate MvRx with you dependency injection framework Write unit tests without worrying about lifecycles or robolectric In under one hour, you can go from MvRx Zero to MvRx Hero.

    Publishing a private app

    Posted: 02 Apr 2019 11:49 AM PDT

    I wish to publish a private application to the Play Store, something whose access I can control.

    Google asks for an 'Organization Code'. What is that and how do I get that?

    If someone has something like this, help would be appreciated.

    How to identify Sensor Calibration is required or not?

    Posted: 02 Apr 2019 07:59 AM PDT

    Hi devs,

    I have an app that makes use of sensors a lot and it requires me to show calibration message "Wave in pattern of 8 to calibrate".

    To Identify if calibration is required or not, I use the following callback from the SensorEventListener

    public void onAccuracyChanged(Sensor sensor, int accuracy) { //indicate sensor values accuracy state if (accuracy != SensorManager.SENSOR_STATUS_ACCURACY_HIGH){ //calibration is required } }

    THE PROBLEM: it doesn't seem to work most of the time. How reliable is this information? How do compass app identify if calibration is required or not, using this or something else?

    I have taken care while testing - like being away from magnetic devices and things, and observed multiple times that sensor values were wrong/random, but the accuracy returned by the callback was SensorManager.SENSOR_STATUS_ACCURACY_HIGH

    ​

    So, How to identify Sensor Calibration is required or not? Is there any other way to identify if Calibration is required?

    ​

    Any help will be greatly appreciated. Thanks in advance!

    ​

    Want to make a simple DAW app for Android for my portfolio.

    Posted: 02 Apr 2019 11:43 AM PDT

    Hey,

    I'm trying to land a better Dev job than the one I currently got (it's mostly manual QA, but lately I do nothing at work...). I want to make my first app from scratch for my portfolio. I've been reading Head First Java and came across their midi app section and thought that would be a great project for me to attempt.

    So, is there any documentation or tutorials out there to help guide me? If anyone has any advice on where to look or even how to get started, I'd greatly appreciate it.

    Thanks!

    Optimizing recyclerView containing a thumbnail which is taken from the internet and a videoView which also loads a video from the internet

    Posted: 02 Apr 2019 07:31 AM PDT

    So, this is a bit complicated, but I'll break it down. So I need to make a recyclerView which contains a thumbnails and a videoView, although these are optional, i.e, there are Boolean values which are checked to which will mark these views as visible or invisible depending on the Boolean.

    Here are the problems I'm facing:-

    1. The feed is kinda laggy, I mean this could just be my device but when it's loading thumbnails it is laggy, but when I scroll back up it's smooth as the images are cached.

    2. The default videoView library in Android seems kinda not for this job, as I want autoplay when the user has that particular card in front and autopause when the card goes out.

    Any suggestions? Thank you.

    Colornote showing alert about new app they made with only "install" button

    Posted: 02 Apr 2019 04:43 AM PDT

    So I opened colornote last night (an app that's usually editor's choice) and got a popup saying something like "hey, we made a new text editor called xyz, check it out." with a picture and one button "install". i thought this was against the tos?

    App Links in a multi-app ecosystem

    Selectively mark views as redacted / secure

    Posted: 02 Apr 2019 01:53 PM PDT

    At the moment I mark an entire window with FLAG_SECURE to prevent my app appearing in the recent a menu and to prevent screenshots on sensitive screens. This works great until users have a bug and resort to photocopying their phone because they can't take screenshots. (I'm not joking in the photocopying btw).

    On the one hand I want the same functionality that this flag brings, but on the other hand I want users to be able to take screenshots without exposing their sensitive data. For context this would be bank account balances.

    I know I could simply take the view that I shouldn't use the flag in this case but is there a way I can selectively mark views in the xml layout to be redacted upon taking a screenshot?

    Using a database with a recyclerview

    Posted: 02 Apr 2019 10:22 AM PDT

    Why is this so difficult! I have made a content provider which successfully writes / reads to and from the database. After - for example - my insert I call `getContext().getContentResolver().notifyChange(newUri, null);`. I have a recyclerview adapter which contains a cursor adapter as a member. I'm setting this up using a cursor passed in at construction time.

    ​

    The recycler view shows the items all well and good, but when I add a new item (using a dialog as it's a simple todo mess around), the new item is not added to the recyclerview.

    ​

    How do I deal with this. Everything I find has been a few years out of date. If the recyclerview is to replace the ListView surely Android would have the necessary means to do basic things like work with a database!

    New app, Newb customer, Outsourced dev

    Posted: 02 Apr 2019 10:02 AM PDT

    I'm going through the process of outsourcing the development work for a new app and am running into several issues and lots of concern...the freelance pool (Upwork, Freelancer) seems to be a cesspool of fakes and would be scammers. I'm not exactly going straight for lowest cost, but I can't afford an agency either. I do my best to weed out the phonies by dicing deep on their profiles and conducting interviews. If anything at all seems out of place, I move on to the next. I've found one developer the appears legit from what I can tell, but my spidy senses are still tingling.

    What are some suggestions for things to keep in mind as I cautiously wade through this process? I've found some boilerplate contractual language to use. I haven't yet found a way to validate the code and most importantly to me, do a security check on. I'm not looking forward to getting the final product as an app I'm going to have to lower defenses and side load.

    Ideally of course I'd do all the development myself. I just don't have the skills.

    Content curation legal in app?

    Posted: 02 Apr 2019 12:38 AM PDT

    Hi guys,

    To which extend is it legal and free to create an app that curates content? For example, the app is about penguins and you show various articles about penguins written by other people including their pictures.
