According to play console the day 1,7,30 retention is way over the average, the crash rate is much lower then the average, the rating of the game is stable 4.7+. Do you have any idea why is this happening?

I posted my apps on Amazon several years ago and one of them is ranked number 7 in paid downloads in its niche. Easy money.

Samsung now accepts anyone's apps without their sdk

A lot of posts make it sound impossible to create a lucrative app. What makes generating app revenue so difficult

How can an open source app by me can be more secure than closed source?

Posted: 28 Jun 2020 03:33 AM PDT

Okay simple question, I'm planning making an app and I am debating with myself whether I should make it OS or not. If I make an app now, why should anybody review it, except people doing it to expose it in whatever way? If nobody looks at my source code, except people who are trying to figure out how to get userbased data for exmple, how can open source be more secure?

I understand that something big is reviewed a lot and it makes sense that it's open source, I just don't think anyone with good things in mind would ever bother looking at my source code, because: why?

So I'd like to get some opinions on what you think about this and what I should do. Thanks a lot

Mistakenly made a production release.

Posted: 28 Jun 2020 03:22 AM PDT

Hi guys,

I'm in panic. My app doesn't work yet and I made a production release from alpha in the Google Play Console mistakenly. What can I do to reverse this?

Kotlin Multiplatform vs Flutter

Posted: 28 Jun 2020 06:58 AM PDT

Hello everyone.

These days everyone seems to be on the wrong direction :<

The trend is all about flutter with its custom libraries that are not built based on the native platform api (android or ios) , just mimics it .

While on the other hand , Kotlin multiplatform with it's "cinterop" seems to be the right and logical choice for me . I don't have much experience at all . So i want to hear from the pros .

Thank you .

Hello friends, I hope you are well

So I've been working on a vr archviz project in unreal engine 4.25 and now I am at the point when i should play my project on vr glasses (oculus go), I installed android studio pack (ndk,sdk,jdk) but I need these "distribution signing keys" (key store,key alias,key store password) and I can't seem to find them.

If you can help me I would appreciate so much Thanks

newbie help, how to implement a file picker?

Posted: 28 Jun 2020 06:13 AM PDT

Hi, I'm very new to android development, and I wanna know how to make a file picker or implement something that lets the user pick a file, and returns the path of it, so my application can access it, I've tried a OPEN_DOCUMENT & GET_CONTENT intent method but always get some different path that ends in numbers ,not sure how to work with it

Thanks in advance, I'm working in Kotlin, minimum api android 6

edit: I'm thinking best way to do this is to maybe use GET_DOCUMENT to copy the file to my apps data directory, but still unsure of how I'd copy it after sending the intent

the context of this app is a very simple file uploader

Unsolvable AdMob issue from Google, unfixed for the last three months

Posted: 28 Jun 2020 05:25 AM PDT

Greetings to the AndroidDev community 🖐,

I've been using AdMob for over a year now, but in March 2020, I got this sudden issue. This means that I get around 3-10% match rate for my ads at best, meaning that pretty much none of my ads work. I went through all the Google Forums and saw hundreds that has this issue, but the only solution Google provides is an unhelpful "Continue to develop your app and hope for the best!".

All of my ad traffic has been organic, I tried to reset my ad IDs etc. but nothing seems to work. Is there anyone else that had this issue, and I would be greatful if I can get a more definitive and logical solution other than what is already provided to us by Google.

How compile android applications against aar libraries without gradle?

Posted: 28 Jun 2020 01:05 AM PDT

Hi. I'm following this super article about developing an android application without android-studio + gradle:

https://medium.com/@authmane512/how-to-build-an-apk-from-command-line-without-ide-7260e1e22676

Everything's fine, except one little problem.
If i want to compile my application against an .aar library, what should i do?

In article, writer said that we can compile jar libraries with our application like this:
./dx --dex --output=$PROJ/bin/classes.dex $PROJ/*.jar $PROJ/obj

But it won't works for .aar libraries.

Issue with layout

Posted: 27 Jun 2020 11:40 PM PDT

Hello, I'm having an issue with this design, for some reason the list appears over the top of the screen instead of being matching parent as it should be with the constraint layout. Any clue?

<?xml version="1.0" encoding="utf-8"?>
