    Looking at options for adding layout files to an installed app, without updating APK

    Posted: 21 Nov 2021 12:53 AM PST

    I'm looking at the various options for adding layouts to an installed app, without updating the app/apk, and would be interested to hear what the best practices are, or any other interesting ideas.

    The problem: an application that downloads courses, then allows the user to work through them. Some of the pages have questions and I am happy generating those dynamically. Other pages are fairly static but hold more content and so I have created layouts for those.

    Being new to android dev I thought I could download and save them into the layout folder, as I figured this would be the best performance, but I've discovered that is impossible.(?)

    These seem to be the available options, using:

    1. my persistent storage, using filesDir. Problem: I get a warning saying that this access is runBlocking, which seems to say that it isn't intended for regular loading?

    2. a local database (Room), holding the layout pages that I generate dynamically for every page in the course

    3. External storage, but this doesn't seem like a good option as it is not reliable/predictable

    4. Is there anything else?

    EDIT: The reason performance is so relevant, is because I'm aiming for the very bottom of the market, the slowest oldest weakest phones possible, and so being able to reload static pages should be faster than generating everything dynamically, especially if the course is reused

    Thank you!

    Google Play strike

    Posted: 21 Nov 2021 05:33 AM PST

    Hello guys!

    So, umm, recently I've got my app suspended because of copyright things.

    And it's not a big deal for me, but there is something I'm really worrying about and I hope if some of you can tell me about this thing.

    I've read about app suspension and in Google Play support page and have found the following sentence:

    (suspension) "Count as strikes against the good standing of your Google Play Developer account."

    What does this even means? Does it works like a YouTube strikes? Will it recude the amount of people that can find my app? Will it somehow have an influence on my eCPM?

    Thanks for your time!

    Recently got hired as an android developer, need some guide/tutorial/book suggestions

    Posted: 21 Nov 2021 06:23 AM PST

    I only need java material for now, to finish a project the guy before me had already started (will learn kotlin in the future). Java has been my main language for 3-4 years, but I feel kinda lost trying to build an app. It seems much more complicated than it needs to be. Fragments, inflaters, and a hundred more concepts I have to understand why they even exist in the first place. I am a mathematician with a minor in computer science, so I could also use some help with how servers/databases/parallel processing etc work, 3rd-4th year cs degree stuff that might be needed for app development. I did take an extra year of cs classes but they were all focused on AI. Any help appreciated :<

    Dear developers, would continue learning XML or start learning Jetpack Compose be more convenient?

    Posted: 20 Nov 2021 04:14 PM PST

    Edit: Looks like most votes insist jetpack, feel free to why along with amy resources that help; from my understanding it's still relatively new.

    Do you use Google Play reviews for marketing?

    Posted: 20 Nov 2021 03:42 PM PST

    After searching the Google Play's terms and conditions, was not able to find any information in this. Do you usually use reviews for marketing and is this permitted?

    App Ranking

    Posted: 20 Nov 2021 08:13 PM PST

    Hi,

    I am planning to release a new app and pay for Google Ads and Facebook ads probably in the area of 10k downloads a day. How do I prepare my app so that when the paid downloads start coming in my app will be in the top 10 of the Top New Free Android app and in the top in its category? Do I have to have a low crash rating or what?

    Where can I download free XML vector icons?

    Posted: 20 Nov 2021 02:29 PM PST

    I am using AIDE because my desktop can't install Android Studio. Has been a great experience writing the app on my phone, and then running it with the phone afterwards. Thus, I can't use Android Studio's Vector Asset Tool.

    I'm making a simple personal app, so I don't mind generic icons. SVGs are super easy to find, but unfortunately I can't convert them without the tool.

    Is there anywhere I can download ready to use xml vectors?

    Viewing Kotlin Code for Layout made in Layout Editor?

    Posted: 20 Nov 2021 02:05 PM PST

    Is there a way to generate or view Kotlin code for a responsive UI made in the editor with a ConstraintLayout? For example, I'm building an activity that is kinda like a page on instagram, where someone can tap pictures and a new activity pops up with that picture. The layout editor is obviously the fastest way to setup and align my ImageViews, but I need to set their content programmatically. Is something like this possible? Or if I want to do stuff programmatically with code do I need to code the whole layout from the ground up?
