    [OPEN-SOURCE] Safe Dot - iOS 14 privacy in Android

    Posted: 13 Oct 2020 04:47 AM PDT

    I've recently built an app that mimics the iOS 14's privacy feature which alerts the user when third-party app uses your device camera or microphone.

    Link to Google Play : https://play.google.com/store/apps/details?id=com.aravi.dot

    So, the thing is I'm not really good at programming yet. I can build things and make them work but I can't make them efficient and 100% bug free. So I need help from you guys.

    I've made the source code open-source feel free to contribute to the app even it can be a translation to your language it really is helpful.

    Here is the link to the repo : https://github.com/kamaravichow/safe-dot-android

    If you have any suggestions or found bugs in the app feel free to use issues section in the repo or the comments of this post. I'll be happy to respond 😃.

    Animating photos using OpenGL ES

    Posted: 13 Oct 2020 05:59 AM PDT

    I made an app which uses OpenGL ES fragment shaders and PyTorch foreground object segmentation to create live photo filters.

    This is my first project working with the GPU.

    Some interesting tech details:

    -The color matching when using live background is achieved by exporting color lookup tables (LUTs) from photoshop and applying them by a custom fragment shader.

    -The foreground object segmentation model is U2Net

    -Some shaders are from Shadertoy (pretty large collection of fragment shaders)

    Is it really that difficult to get app downloads as a new developer on the Play Store?

    Posted: 13 Oct 2020 01:02 AM PDT

    I have heard many developers say that it is very difficult to get downloads on the Google Play store. Especially when people are downloading less apps and keeping fewer apps on their devices, how has the struggle been for new developers?

    I am curious to know this because I am currently developing an app and want to be aware of all of this. I would love to hear thoughts from other Android developers! Thank you for all those who respond!

    DeepLinkDispatch not working in Kotlin

    Posted: 13 Oct 2020 08:21 AM PDT

    Hello, guys. I was using DeepLinkDispatch perfectly with a Java version of my app, but when I migrated to kotlin isn't working. The app is catching the link and it's opening perfectly the activity but the problem is I cannot access to the query parameter, I was watching the URI is parsed to something different I had on the original link. Does anybody how to solve it?

    I attach an example of how it's working:

    Original URL: abc://path/?id=45 Parses URL: abc://path/{id}

    On the activity I tried writing the link as follows:

    abc://path/?id={id} abc://path/{id} abc://parh/

    But no one is working, all give me the same results. If there's another way to use deeplinks I'm glad to try it too.

    Flipper increases release size by more than 10 MB. Alternatives?

    Posted: 13 Oct 2020 08:18 AM PDT

    I added flipper today to my app today but recently i noticed that it's getting attached to release builds too. If I do the following, it will show error while building release builds, giving error related to network plugin and if i just make it api for all then they get included in release builds and increase app size by 10MB. Are there any alternatives or a way around?

    debugApi 'com.facebook.flipper:flipper:0.62.0'
    debugApi 'com.facebook.soloader:soloader:0.9.0'
    debugApi 'com.facebook.flipper:flipper-network-plugin:0.62.0'
    releaseApi 'com.facebook.flipper:flipper-noop:0.62.0'

    Beta Rollout review time?

    Posted: 13 Oct 2020 07:24 AM PDT

    Hey everyone, I uploaded a beta rollout and have updated the version a few times (15 times). I have pushed a new version and now I have been waiting 4 days for review. Usually it only took about half a day for the beta version review. How long might this take?

    Storybook UI component explorer but for Android?

    Posted: 13 Oct 2020 05:52 AM PDT

    I'm looking to visualize my Android component library, and have used a solution called Storybook JS in the past for Javascript component libraries. Is there a similar solution for Android? Specifically Kotlin.

    Has anyone figured out the secure implementation of HostNameVerifier ?

    Posted: 13 Oct 2020 05:40 AM PDT

    This is my current implementation:

    private HostnameVerifier getHostnameVerifier(final URL url) {

    return new HostnameVerifier() {

    public boolean verify(String hostname, SSLSession session) {

    String host_name = "examplesomething.com"

    if(url.getHost().equals(host_name) && session.getPeerHost().equals(host_name)){

    return true;

    }else{

    return false;

    }

    }

    };

    ​

    Even the official google support page here gives the same advice:

    If you are using the HostnameVerifier interface, change the implementation of the verify) method to return false whenever the hostname of the server does not meet your expectations.

    ​

    Even then i still get insecure implementation of HostnameVerifier Error. Any ideas why? Thank you

    How to get back into shared Play Console account?

    Posted: 13 Oct 2020 05:12 AM PDT

    A few months ago an organization invited me into their account to deploy an App, I logged in and created some of the info for the App, images etc.

    Today I logged back into my console account and cant find how to get back into the other shared account, would I receive any notification if I get removed or access expires?

    On the top right profile/dropdown thing there is "manage dev accounts" but they only lead to a screen to select my own gmail accounts.

    C++ Programmer here, where to learn Kotlin ?

    Posted: 12 Oct 2020 11:32 PM PDT

    I'm a C++ programmer and I've knowledge of OOPs concepts and data structures.

    Now I've decided to learn how to create apps. So that I can put some projects in my resume and publish my ideas to play store.

    I've decided to learn Kotlin over Java (hope this is a good decision), is there any book or course or online tutorial to get started?

    I'm sorry if this type of question is not allowed here, I thought you real developers will give honest advice from your experience rather than selling me a course.

    Thanks in advance.

    Anybody know where the Android Version distribution chart is on the new Play Console?

    Posted: 12 Oct 2020 10:30 AM PDT

    The old play console had a page where you could see a distribution of installed devices' Android version. I can't find it anywhere on the new play console.

    EDIT: To clarify, I'm talking about the distribution of Android device versions that has your app installed on it. For example, this is to find out how many of your users are still on API Level 19 (Android 4.0) and how many are on Level 21.

    Websockets and repository pattern - where to initialize connection

    Posted: 12 Oct 2020 08:01 AM PDT

    Recently I have been playing around with a multiplatform, text-based, chat application. I have a repository class which is meant to abstract data accessing for messages. Ideally this will also abstract away the websocket connection I have to my server.

    One of the things that I am not sure about is where to initialize this websocket connection. I don't usually think of repositories as having a lifecycle, but it seems if I initialize the connection there, it inherently must have one.

    If I choose to injection route for the websocket connection, still the question remains of where do I initialize it. Does my view model initialize it and then pass it to a repository? What happens when the connections drops and I need to try and reconnect?

    Looking for general input on this question

    Remote compilation for instant builds.

    Posted: 12 Oct 2020 11:34 AM PDT

    Hi,

    I have created a small project which speeds the local build by compiling the code on a remote extremely powerful server. It can reduce the compile/build time by about 50%.

    What do you think about it?

    Securing Mobile Apps... Any resources?

    Posted: 12 Oct 2020 11:21 AM PDT

    I am looking to learn about securing mobile apps. Not just Android but I figure many of the same ideas would apply across platforms. Are there any good resources to get started that this group can recommend? I am interested in everything from network protocols, certificates, UX design, memory protection, etc.

    Backend Python and frontend Java?

    Posted: 12 Oct 2020 02:41 PM PDT

    Hey people, I'm new in programming and my friend and I have graduate project for next term.

    Project's goal is to have Android App which runs FFT functions( already have in Scipy) and shows the plots of frequency.

    We will collect frequency data from sensors on the pump via bluetooth then apply FFT on it.

    How is it possible to get data via bluetooth on Android phone and make it on python?

    ​

    I've heard about kivy framework but kivy doesn't support scipy library.

    is it possible that frontend java and backend python for this kind of application?

    what do you suggest?

    ​

    Thanks :)
