Apple & Google are about to be weakened, remember when we used to talk about Google's bad practices & some developers here would fight for Google? LOL! However, I have seen that over time, even those devs have understood the terrible behavior of these Tech Giants in respect to App Developers.

I just released my first (open source) app, BootyCrate

Posted: 12 Sep 2021 05:57 AM PDT

Hi all, I just released my first open source free shopping list / inventory app, BootyCrate, on the Play Store. Yes, it's called BootyCrate. Booty as in treasure / loot / stuff :3

I was inspired to make BootyCrate because I didn't know of any grocery shopping list app that also let you keep track of an inventory of frequently bought items. BootyCrate allows you to manage an inventory of items and a shopping list. Items in your inventory can be added to your shopping list manually, or when they fall below a certain amount. For infrequently bought items they can also be added to the shopping list as a one-off item. In the settings there is an option for a one time or repeating reminder notification to be sent to remind you to update your shopping list / inventory.

As of right now it's pretty feature sparse because I spent so long trying to get the UI/UX and animations looking right, but I hope to add more features in the future. If you'd like to look at the code, I added another readme in the Kotlin source directory that gives a brief overview of the subpackages in the project and the inheritance chain of the major components (e.g. the RecyclerViews used to display the shopping list and inventory). While I didn't write documentation for every single function of every single class in the cases where I thought they were fairly self-explanatory, all classes and loose functions have an overview written for them. The app is 100% Kotlin, uses MVVM and Kotlin coroutines (though with no repository at the moment), and has a very small amount of unit testing, and a bit more Espresso testing (but still not complete).

Any feedback is welcome. Hope you all enjoy it.

I don't understand the need for unit tests

Posted: 12 Sep 2021 12:19 AM PDT

Can someone please give me exact examples when tests helped you? Everyone says how important they are but in my experience I don't remember a single time they helped me, they eat around 20% of additional development time + constant maintenance.

Facebook disabled my dating app because I use an age filter

Posted: 11 Sep 2021 06:05 PM PDT

I use Facebook Login for authentication. Recently they asked developers to fill in a Data Check form. One of the questions was asking if your app discriminates based on age, and I said yes because that's basically a necessity in every dating app (to allow users to choose the minimum and maximum age of people they want to match with).

After saying I do discriminate, they immediately disabled my app, saying I'm in breach of:

Platform Terms 3.a.i: Prohibited Practices. You will not perform, or facilitate or support others in performing, any of the following prohibited practices (collectively, "Prohibited Practices"): Processing Platform Data to discriminate or encourage discrimination against people based on personal attributes including race, ethnicity, color, national origin, religion, age, sex, sexual orientation, gender identity, family status, disability, medical or genetic condition, or any other categories prohibited by applicable law, regulation, or Facebook policy.

Is this a serious policy, or did they interpret my app wrong?

Tinder still uses Facebook login and the age filter, so if it was the case, there is a clear discrimination on their end towards smaller developers.

Android EMM - “Android Settings” not visible + zero-touch enrolment questions

Posted: 12 Sep 2021 04:08 AM PDT

Hey guys,

After some help and hoping this community has some experience in this.

I'm currently working through some mobile device management configuration in an effort to work towards a zero-touch enrolment for a mobile fleet of Android devices running an Android app we're currently developing, I'd appreciate if anyone can assist here.

The link here asks to browse to Android Settings, but it is not visible in the menu described, do you have any suggestions as to why?

Ideally the desired state configuration would be to have one Gsuite/Workspace account that all devices in the mobile fleet would initially sign on with, and then as a result I would imagine adopt a zero touch configuration that would push the required app to the device, remove any bloat, manage auto-updating, auto-load our app, and prevent the app from being closed. If there's options for remote control/screen view, that would be amazing too.

Our devices in the fleet will be installed in a customer environment with our app functioning during business hours, I would very much like the client to have little to no maintenance requirements or interaction with the device configuration/administration outside our apps interface.

Would really appreciate any and all suggestions to both the first issue around Android settings and some things that could point me in the right direction to the desired zero-touch enrolment.

Cheers!

Recover data (contacts) from P9 Lite with broken touchscreen

Posted: 12 Sep 2021 07:22 AM PDT

My dad Huawei P9 Lite touchscreen stopped working after 4 years of service. Everything else still seems to work including the side buttons.

Sadly he didn't link his contact to his Google account so it would be great to find a solution to get them out of the phone. Luckily he saved pictures in a microSD so that's not an issue.

I am 99% sure he didn't enable USB debugging so I can't use the basic recovery programs to do it. I am gonna try with a USB mouse tomorrow but I am afraid it won't work with the P9 Lite.

Is there anything else I could try to do?

What is warning 703 and warning 701 in MediaPlayer

Posted: 12 Sep 2021 06:03 AM PDT

After being annoyed with spotify ads I developed my own music system but it often throws these two warning 701 and 703 and the music stops I researched a bit and the sites say the warning occurs when there is not enough cache for the music to play or in simple terms the network is slow but my device is connected to a solid 150mbps network. I would appreciate if someone can explain the warning and also provide a solution or a way around it. Thanks!
