    Weekly "anything goes" thread!

    Here's your chance to talk about whatever!

    Although if you're thinking about getting feedback on an app, you should wait until tomorrow's App Feedback thread.

    Remember that while you can talk about any topic, being a jerk is still not allowed.

    What are your thoughts on MoPub?

    Posted: 03 Jan 2020 10:42 AM PST

    Do you have any experience with them? I am looking for a serious ad network for mediation but for some reason they seem shady, and something about them just doesn't feel right. From their policy to how they collect and manage user data.

    Have you worked with MoPub? What are your thoughts on MoPub?

    What are some use-cases for EncryptedSharedPreferences?

    Posted: 03 Jan 2020 07:46 AM PST

    EncryptedSharedPreferences

    What are some practical use-cases for EncryptedSharedPreferences? I originally wanted to use it to store some user credit card information, but there aren't many discussions surrounding if/why this is a good/bad idea.

    Android dev here, what could I use to make a desktop app?

    Posted: 03 Jan 2020 12:50 PM PST

    Hello

    I am an Android developer with decent experience, both using java and kotlin, but now I want to make a desktop app. I use Linux, so that would be my target OS, but it also running on Windows and or Mac would be a nice plus.

    I don't want to run an Android app on my desktop in an emulator (don't know if there is a way to do that with good integration with the desktop, clipboard, that also doesn't swallow all my ram), instead I want to know what I could try that might be more familiar to an Android developer, like some java framework or something high level, not plain java... you get the idea... kotlin native seems too low level and not fully stable, but I don't know, you tell me...

    Thanks!

    EDIT: I rememberd about Ambox, haven't tried it (yet).

    Anyone come across a good real device testing farm which supports Samsung Galaxy S10 Android 10?

    Posted: 03 Jan 2020 08:53 AM PST

    These few days, I have been searching and testing around various real device testing farm, to look for device Samsung Galaxy S10 Android 10. So far, I am not able to find a good one.

    • https://kobiton.com/ - Their testing facility is great. But, they don't come with Samsung Galaxy S10 Android 10. Contact their customer support for few time. No respond at all. Bad!
    • https://www.browserstack.com/ - Their testing facility is great. But, they don't come with Samsung Galaxy S10 Android 10. Contact their customer support. According to them, they do not have ETA to support Samsung Galaxy S10 Android 10. Ok.
    • https://saucelabs.com/ - Their testing facility is slow. However, they come with Samsung Galaxy S10 Android 10. But, their testing facility lack of an important feature. While you are running your old version of app, you cannot upload and install a newer version of app. This is important, as we need to simulate DB migration code as well. Without this feature, such testing is useless for us.

    Have anyone come across a good real device testing farm which supports Samsung Galaxy S10 Android 10?

    Thanks.

    What are the best resources to get back into Android development?

    Posted: 03 Jan 2020 07:58 AM PST

    A few years (pre-Kotlin and Fragments were the new kid on the block) ago I developed a couple Android apps and I would like to get back into it, but a lot has changed since then.

    Can anyone recommend some resources to get familiar with the best practices and what previous patterns need to be avoided?

    What's in your cart?

    Posted: 03 Jan 2020 08:14 AM PST

    I'm collecting opinions on how to implement a shopping cart. In this scenario, the user can only shop from one store at a time, which makes the shopping cart very dynamic and disposable. Therefore, should I store this cart online or have it saved offline, for example using a shared preference?

    Is it normal that mobile games tend to be performing on one platform?

    Posted: 03 Jan 2020 01:48 AM PST

    Hey fellow android devs,

    I have a weird problem. I released two games of mine quite a while ago the first one was Flat Fat Cat Bounce a physic based cat puzzle. I released it on PlayStore and AppStore at almost the same time with some what the same store descriptions, trailer, images etc. Today I have about 81% Android and 19% iOS for that game so far so good.

    But now the weird part I made a second game Space Unicorns, which is actually just a reskinning of Flat Fat Cat Bounce, instead of having cats we have unicorns with the same mechanics and game play. I also released that one on PlayStore and AppStore and the weird thing is for this game I have 91,2% iOS and only 8,8% Android.

    I can't really explain why that is so different and if it is just random or what ever. May be you encountered something similiar? Or is just normal?

    Android studio image filters

    Posted: 03 Jan 2020 07:07 AM PST

    I tried some libraries for image Filters, but all of them caused my app to lag and/or crash, how can I use filters which don't lag? I already tried multi thread but that was just semi good working, eg. the app crashed on some pictures, but I couldn't find why these pictures caused the app to crash, thanks in advance for any Help :)

    EDIT: I tried this library https://github.com/mukeshsolanki/photofilter and this is also currently the library I use in my code, there isnt really a stacktrace, it just times out, its an issue with the memory, this is the code I currently use:

    https://throwbin.io/K1vtEop 

    Then a button starts the thread, this works good for small pictures, but when I use photos from the actuall camera, which takes larger pictures, it wont filter anymore, so how can I achieve that also photos can be used?

    Hi, i have seen some apps in which their developers adds an option for "translate for us"

    They upload their string resources to some website and user can download and translate their strings from that website.

    I don't know about that website can you suggest a good one?

    Posted: 03 Jan 2020 05:16 AM PST

    Recently i started developing an app for play store, which is basically a game. And i wanted to upload it to the play store. Now it turns out you need to pay 25 dollars for a developer account. So, i asked my parents to buy the developer account for me but theu refused to do so. they told me to study and not waste time on making apps. im 15 btw and really interested in app development. Ive written this post to ask for help from you guys, does anyone have a developer account which could be lent to me or something? Or can i publish my app through your account? Thanks in advance.
