    Flutter vs React Native ?

    Posted: 10 Feb 2020 10:11 AM PST

    Hi all , I'm working on a fresh side project and I'd like to get some opinions about this.

    On one hand , I'm a very experience JS dev. I roughly know exactly how to build what I need with React Native. But I'm getting sick of JavaScript. I stare at it all day. And while React Native is great when it works , some days it feels like a hacked together mess. I still prefer it over native Android though.

    Dart FEELs fresh , and assuming it has good code completion I might try to get something started with it. The big downside with Dart is a lack libraries compared to React Native.

    A third option is typescript. My biggest issue with JS is in any project of scale it's harder to keep things organized. Obviously Typescript was created to address this issue.

    Question: activity memory leaks

    Posted: 10 Feb 2020 02:02 PM PST

    Can passing activity object to any class cause memory leaks?

    Like the comment mentioned here: https://stackoverflow.com/a/59138362/3996989 "any of the code that is keeping reference to an activity it can cause the memory leak"

    Is this statement true?

    Worth learning kotlin or Java first?

    Posted: 10 Feb 2020 10:04 AM PST

    So I was going through google codelabs for Java initially but noticed after AndroidX I'd like to keep up with latest libs. Except newer tutorials are in Kotlin. Should I just skip right ahead to doing it in Kotlin? I did get to section 4.5 of the Java codelabs, so I have an idea of how things work.

    Help with implementing Google Drive API

    Posted: 10 Feb 2020 09:19 AM PST

    Hi, I need my application to be able to upload files to Google Drive.

    I'm still new to Android, so I found on Google for tutorials, but what I found was that Drive has a kinda new API and I don't find anything that helps me understand how it works or helps me build it, I found a couple of tutorials but always ending in errors I don't know how to fix, so if someone can help me out a little would be very nice, otherwise I guess I need to keep searching.

    Thanks!

    Looking for a practical testing tutorial/course

    Posted: 10 Feb 2020 09:17 AM PST

    I know the basic syntax of android testing. I know how to create UI and unit tests. Now I'm looking for some good examples of how you can implement and leverage tests in real app. Free and paid content is ok.

    How effective is PPC to get your app up into the top SERP pages?

    Posted: 10 Feb 2020 09:26 AM PST

    Obviously if you run a PPC campaign that you will get a large number of installs proportional to your ad spend.

    However, I suspect that there's another big win in that the total # of installs means that you're going to place higher up in SERP pages for key terms since Google ranks by the number of reviews and active installs.

    My theory is that there's a sweet spot where you can throw down $1-10k and get into the top ranking apps MUCH faster than you would otherwise.

    Any thoughts here?

    Suggestion on where to begin to develop a navigation system like google maps but for indoors.

    Posted: 10 Feb 2020 09:23 AM PST

    hi,

    i'm new developing apps for android, and i want to know where to start developing a indoor map navigation system, i mean, i want to know how to have navigate trough a map that i upload to my app.

    Neither of the solution online helped me, i mean, i don't need to use maps from the world, i will create the indoor maps with a CAD software or something like that, i want to be able to zoom in, make a pathfinder, etc.

    Looking for a place to earn

    Posted: 10 Feb 2020 08:41 AM PST

    So I'm completely new to this subject (the very basis of Java is all I got) and I finished a simple app today using android studio (basically drag and drop I guess). I got this course from Udemy but I don't understand a thing he types in.

    Is there a place I can learn this? I used MOOC.fi for Java and would appreciate a site like that. Or would it help if I just memorize the stuff in the course I mentioned?

    Is there any image morphing transition library available that i can use in android studio?

    Posted: 10 Feb 2020 04:10 AM PST

    So when i switch from one image to another, the picture should morph itself to the next image by keeping the constant features of the image unchanged and rest of the image just warping to the new one. The two images are pretty much similar to one another (i.e they have mostly have same background or 80% remains same). If it's not available then what's the best way to achieve this?

    LPT : If your minSdk is too low to enable "apply changes", add a new flavour with a higher minSdk and do all the development on it.

    Hardware acceleration for the ARM Android Emulator

    Posted: 10 Feb 2020 02:16 AM PST

    I need to run the app I'm developing on an ARM device and my workflow would be so much easier if I could use a virtual device. I.e. an Android Emulator.

    Is it possible to achieve graphics hardware acceleration on any emulated ARM Android?
