    My personal library of Kotlin extensions that might be useful

    Posted: 18 Mar 2020 04:29 AM PDT

    Hey folks, I'm sharing my personal library that I use in every project of mine, it has things found working from StackOverflow to things I've written personally to take shortcuts, copied some from Github and modified them to work as intended just to make the Android development easier.

    Github Link

    It lacks documentation, feel free to contribute or to use it in your projects, pull requests are welcomed as well as if something doesn't work feel free to open an issue or if you find your code add headers/credits that's yours and make a pull request.

    Google Removed my app without any heads up, they said we were uploading users' contact info but we are not doing this. We use the Contacts API to send SMSs but never storing this data. Have anyone experience this issue before?

    How will location permission changes in android 11 effect my app?

    Posted: 18 Mar 2020 12:41 AM PDT

    I work on a app which collects user data with his permission (we give justification and only collect if user accepts it).

    Location is the most important part of the data i am collecting. It is collected every 2 hrs, only when permission is given and GPS is turned on. Currently, app target SDK is 28, So i have not added BACKGROUND permission yet.

    I read the developer blog and understood things. What i am not able to understand is how google play policy changes and increasing target SDK version to 29 , 30 impact my app separately.

    Will i have to show permission dialog every 2hrs?

    Any other way to get location with reduced accuracy and not going through all this pain of changed policies?

    Is indoor automatic positioning possible with AR?

    Posted: 18 Mar 2020 06:12 AM PDT

    i read a lot of projects about indoor navigation but all of them require to set the start location and every time the user need initially to be in this location, in some cases it is not beneficial such as for blind users, is there a way to detect the position automatically using the available SDK such as ARCore and ARKit or this technology still doesn't exist?!!

    End of Google Play Games Multiplayer

    Posted: 18 Mar 2020 05:01 AM PDT

    A few weeks ago I shared a video about using Firebase to create multiplayer game: https://www.youtube.com/watch?v=nj-trslVFPc

    Now I want to share simple logic to connect devices that can be implemented in your own server: https://www.youtube.com/watch?v=0Pg5s6VJOqI

    Both of these can help you migrate to new multiplayer system by the end of March.

    What should I use to make animations and transitions in android?

    Posted: 18 Mar 2020 04:56 AM PDT

    I looked to the docs and I've found so many long docs talking about making animations from xml resources (sets, translate ... object animator, value animator) to programmatic code (Scenes, Transition's custom animations, ViewAnimationUtils), and there's also MotionLayout which is in beta 4 at the current time.

    I'm kinda lost with all of these, is Motion layout the go to from now on for all animations?

    GitHub App is now officially available on Android

    Posted: 18 Mar 2020 07:27 AM PDT

    Anyone use a CMS?

    Posted: 18 Mar 2020 06:58 AM PDT

    I recently started a new project where one of the requirements is to be able to have some of the content in the app to be dynamically changed by non-developers and without requiring a new release. I've used Contentful and Firebase in the past for frontend and it seems to be doable on Android (and iOS for that matter) but I'm curious if there are issues or limitations of this approach?

    My biggest concern is during the approval process since the content being dynamic means that they would not be able to guarantee the content stays the same.

    Has anybody done this before?

    How do you decide on which devices to support when developing an Android app?

    Posted: 17 Mar 2020 10:11 PM PDT

    I want to ask a question about how you decide which devices to support when developing an app.

    We are developing Unity apps that use sensors like compass, gyroscope, and accelerometer. There are so many cheap Android devices out there that have these sensors but aren't accurate enough. We need to figure out a list of devices that we can support, and it's YMMV for the rest of the devices. We cannot practically buy every device that exists out there and support each and every one of them.

    We think that market share stats by the device (not the manufacturer) will give us a good starting point to limit the number of devices we want to officially support. Since there is no such data available officially from Google or Apple, can anyone recommend a good source for this info? I suppose there are companies built around this kind of thing?

    Or is there a better way of doing this?

    I appreciate your input.

    Best FinTech Apps: Trends in the Mobile Age

    Best FinTech Apps: Trends in the Mobile Age

    https://preview.redd.it/12lublzlqfn41.jpg?width=741&format=pjpg&auto=webp&s=d617c9976e796b4f69a462f0e5ddad88338e92a4

    Along with the increasing growth in mobile phone usage, mobile applications become more and more widespread. As a result, FinTech apps aggressively entered the market. Currently, the best FinTech apps are focused on developing a fast, responsive, and customer-friendly app to use.

    FinTech is a nickname for solutions that bring about financial exchanges. FinTech is the short term for "financial technology". It covers a wide scope, including:

    • Blockchain solutions
    • Digital wallets
    • Trading and securities
    • Payment processing
    • Cross-border payments
    • Lending

    The best FinTech apps are more secure and efficient. Financial information provides users with a security and privacy risk, it poses specific challenges to mobile app and software developers. However, FinTech solutions, in their turn, take this into account by combining features such as blockchain, cryptocurrencies, and other secure channels for exchanging sensitive financial information.

    Another feature of FinTech mobile apps is that they also increase efficiency thanks to the automation of some processes as well as offerings of digital options for traditional time-consuming processes, for instance, obtaining signatures on contracts.

    Probably, the most essential feature of the FinTech applications is to simplify financial exchanges by offering better user experiences for those companies whose financial tasks might involve dealing with clients, paying vendors, or exchanging assets in different currencies. Now we may take into consideration that FinTech has implications that influence a broad range of mobile applications.

    Help a noob keep his sanity

    Posted: 18 Mar 2020 04:50 AM PDT

    New to android development, was playing around with some code and came across a problem thats been driving me insane over the past couple days so I thought why not see if anyone else can make any sense of it.

    There's part of the code that's meant to send the users contact list to firebase when they open the app, and it creates a new child under their user in the real-time db with the list, but for some reason it only updates the list when I use the test accounts in my emulator and when I run the apk on my phone with normal accounts, everything else works, but it just doesn't make the new child with the list in firebase. I've checked the permissions, and they're all set to allow, but it just doesn't want to update the list.

    Does anyone have any suggestions as to why this may be happening? I just don't understand why it sends my emulator contact lists, but not my phone's. All help is appreciated, tia

    Is Unity a good engine to develop multi-platform applications (non games)? Are there better alternatives?

    Posted: 18 Mar 2020 02:55 AM PDT

    I wanted to develop a multi-platform (iOS and Android) quiz/trivia game similar to the Brand Logo games. However, I am confused as to what language/engine to use.

    APK Rejected: Policy Coverage

    Posted: 17 Mar 2020 01:18 PM PDT

    I have an Android app with over 10 million downloads, a little over 6 years on the Play Store, has been featured by Google a few times, it is even on Play Pass.

    Well today I tried to do a quick update because of a fairly critical bug I found and it got rejected. This was a very incremental release, very few changes compared to the last release that worked out fine. I do updates all the time, in fact I did one last night that was just fine.

    This is the policy they say I'm violating https://play.google.com/about/enforcement/policy-coverage/

    I have no idea how I could be doing that? is that even possible on Android without asking for permissions?

    Anyone else here had that issue before? what was the fix?

    The text from the link:

    Policy Coverage

    Our policies apply to any content your app displays or links to, including any ads it shows to users and any user-generated content it hosts or links to. Further, they apply to any content from your developer account which is publicly displayed in Google Play, including your developer name and the landing page of your listed developer website.

    We don't allow apps that let users install other apps to their devices. Apps that provide access to other apps, games, or software without installation, including features and experiences provided by third parties, must ensure that all the content they provide access to adheres to all Google Play policies and may also be subject to additional policy reviews.

    Defined terms used in these policies have the same meaning as in the Developer Distribution Agreement (DDA). In addition to complying with these policies and the DDA, the content of your app must be rated in accordance with our Content Rating Guidelines.

    Apps that may be inappropriate for a broad audience or result in a low quality experience for our end users may not be eligible for promotion on Google Play. Such apps will, however, remain available on Google Play so long as they are in compliance with these policies and the DDA.

    Google reserves the discretion to include or remove apps from Google Play. We may take action based on a number of factors including, but not limited to, a pattern of harmful behavior or high risk of abuse. We identify risk of abuse using various items such as previous violation history, user feedback, and use of popular brands, characters, and other assets.

    Edit: After reading this a few dozen times, I'm actually starting to wonder if it has to do with my content rating. I have a low content rating, E in NA. I got that by answering the questions it asked. I'm wondering if maybe I need to just flip some answers even if not true to force it to give me a higher age rating. They even have a question about being a browser and I answered yes on that one. Everyone single one of my competitors that I check has the same rating, which makes sense since we all went through the same questionnaire.
