    Dagger through your heart

    Posted: 31 Oct 2019 10:40 AM PDT

    Has anyone used Dagger and can say it has significantly changed their dev experience? Or is it just one more library that caught on?

    Android projects junior devs can contribute to?

    Posted: 31 Oct 2019 07:24 AM PDT

    While I could learn a lot by building a whole app by myself, it just takes up so much time and I only plan on doing only 1.

    To save time and learn from other devs, I want to work on other projects online, and learn from other peoples commits. does anyone here know where I could find this? I see some online but they aren't very beginner friendly

    What are the top android libraries/frameworks companies look for?

    Posted: 31 Oct 2019 06:50 AM PDT

    Hi everyone, I'm an aspiring junior Android developer and I'm trying to build my portfolio. I see a lot of Android Developer job postings that prefer candidates with certain experiences with libraries and frameworks. Something like Retrofit, Gson, RxJava, etc. I'm not entirely sure what I need to or should learn and use for my projects.

    What do you guys think are the top android lib/frameworks that companies look for?

    Many thanks

    Icon Tryer Outer - a simple tool I built to try out icons on your mobile device

    Posted: 31 Oct 2019 10:14 AM PDT

    Hi folks,

    In recent months I've been getting into iOS development. An issue I've run into is wanting to try out multiple icon designs on my actual device, which can be pretty cumbersome with just Xcode.

    So to scratch this itch I built Icon Tryer Outer: https://www.icontryerouter.com/

    It takes advantage of the "Add to homescreen" feature to let you quickly test out icon designs. You're also given a shareable link that you can give out to others (designers, other engineers, friends, etc) so they can test the icons, too.

    I'm an iOS dev, but I suspect this is an issue for you Android folks as well (and the "Add to home screen" feature is available in Chrome for Android), so I thought I'd post this here!

    I'd love to hear what you think!

    Using LiveData to cache data in repository

    Posted: 31 Oct 2019 11:30 AM PDT

    Hi, I just started using livedata and viewmodel and need help with implementing repository pattern.

    I need to cache data after fetching it from the remote api to avoid calling it multiple times. I also need to have functionality of force refreshing the data from remote api if needed to.

    Is it okay to use LiveData as data holder in the repository, so that whenever I sync the data with remote api, the viewmodel of current activity is automatically refreshed with latest changes or Livedata should strictly not be used in the data layer?

    Noob Advice needed

    Posted: 31 Oct 2019 02:43 PM PDT

    Hi all,

    Coming from react/react natice space to Android and Kotlin. While im checking out some tutorials, i wanted to ask for some input on some issues that i have on my mind, to get some ideas, before I start researching.

    Our project is a new one, and none of my colleagues have any solid experience in android.

    So, here we go:

    • How is proper navigation implemented in android?
    • Whats the best way to implement and maintain a state container (Singleton?)? Coming from react world, i must say i miss redux!

    Thanks for any input!

    Cloudflare for app server/api

    Posted: 31 Oct 2019 02:57 AM PDT

    Hey, do any of you here use cloudflare or some other service to prevent DDOS on your app server?

    They have a free tier and all, I was wondering whether I should use it or not. Would it be worth the performance loss? Idk how big that is thought.

    If it is like on websites ("checking your browser, please allow up to 5 secs"), but thats only the first time thought. Idk how it works exactly, if your using it with your API you could possible enlighten me of the performance loss?

    Using ViewPager2 with JetPack Compose

    Posted: 31 Oct 2019 12:14 PM PDT

    Was kind of blown away by the Dev Summit. Surprised by the breadth and depth. So I am going through now trying to use a little Compose, but also saw the session about how ViewPager has been reworked in ViewPager2 (there's a micro session about it).

    Has anyone tried to use these things together? I am guessing no. I guess I should look at the Compose samples and see if I see anything in there. When it is possible, I think it will be amazing, for now might just use old style views for the time being.

    Thoughts about coreLibraryDesugaringEnabled on the new Android Studio...

    Posted: 31 Oct 2019 01:39 AM PDT

    I've noticed this cool feature that let you use relatively new Android APIs on old versions of the OS:
    https://developer.android.com/studio/preview/features

    https://youtu.be/XPMrnR1_Biw?t=638

    So I wanted to give it a try.

    I remember I had an issue with the IDE that it offered me to replace a tiny Java code to have "Long.compare()" instead of what I wrote, and it caused a crash on older Android versions:
    https://issuetracker.google.com/issues/130141144

    I tried to do it now again, and... for some reason it didn't crash (tested on API 16 emulator), even though I didn't set the new flag yet. Not only that, but this function/class don't seem to be mentioned on the link about what's supported:

    The following set of APIs is supported in this release:

    Sequential streams (java.util.stream
    )

    A subset of java.time

    java.util.function

    Recent additions to java.util.{Map,Collection,Comparator}

    Optionals (java.util.Optional, java.util.OptionalInt
    and java.util.OptionalDouble
    ) and some other new classes useful with the above APIs

    Some additions to java.util.concurrent.atomic
    (new methods on AtomicInteger
    , AtomicLong
    and AtomicReference
    )

    ConcurrentHashMap
    (with bug fixes for Android 5.0)

    So what's going on here? How could it not crash on API 16 ?

    Even the IDE seems confused about this new situation. On one time, it marked "Long.compare" as an error, and later it removed this error. In both cases it agreed to build and run without issues on API 16...

    I've reported it here, BTW, including sample projects.

    As a bonus, I see "A subset of java.time" being mentioned, but it doesn't say what exactly. Maybe I can finally avoid using libraries that implement Localdatetime and similar classes ?

    Weird, and cool...

    Guidelines for implementing analytics in Apps?

    Posted: 31 Oct 2019 12:01 PM PDT

    I am wondering if there are any guidelines for implementing Analytics in Android apps. Have you guys seen any?

    Couldn't personally find any guidelines to implement analytics in Android apps anywhere, so I decided to summarize a few of my findings here, but it's probably lacking:

    https://medium.com/@prototypemakers/analytics-best-practices-for-xamarin-ios-android-apps-223fcd3634f0

    (If you can't get through because of paywall, try to open in Incognito window, or I cross-posted it here: https://github.com/saamerm/OctoberXamarinChallenge/blob/master/analytics-best-practices-for-xamarin-apps.md . It talks about implementation in Xamarin Android, which is basically Android development done in C#)

    Please let me know if you guys have any useful resources.

    MetaData to CSV

    Posted: 31 Oct 2019 05:38 AM PDT

    I have developed an app for a company which is in Playstore now. For the backend, I have used Firebase.

    As of now, there is no native way to export the database to CSV or Excel format. But one can export the Firestore db to a MetaData format (I think that is some kind of Bigquery format) using Google cloud services. But I don't know what to do with that file or how to access that.

    Do anyone know how to convert the firebase database or MetaData format to Csv or sheet type format?

    AndroidX migration - Why Android Studio is refactor com.android.support:support-v4 to androidx.legacy:legacy-support-v4, instead of androidx.appcompat:appcompat

    Posted: 31 Oct 2019 04:12 AM PDT

    I try to migrate one of the old projects to AndroidX, by using Android Studio/ Refactor/ Migrate to AndroidX...

    However, for some of the library projects, when I went through their build.gradle, I notice Android Studio is changing the line from

    implementation 'com.android.support:support-v4:28.0.0' 

    to

    implementation 'androidx.legacy:legacy-support-v4:1.0.0' 

    I was expecting the migrated line should be

    implementation 'androidx.appcompat:appcompat:1.0.0' 

    May I know why it is so? I have tried both 'androidx.legacy:legacy-support-v4:1.0.0' and 'androidx.appcompat:appcompat:1.0.0'. Both of them compiled and execute well.

    But, which is the correct one? The library is using androidx.viewpager.widget.ViewPager

    How to make MaterialButton "merge" with a horizontal divider ?

    Posted: 31 Oct 2019 06:10 AM PDT

    How to make MaterialButton "merge" with a horizontal divider ?

    I'm trying to do something like that:

    https://i.imgur.com/Wy8AAFM.png

    So far I got the button right, but when I try to put it on top of the divider it has some spacing:

    https://preview.redd.it/qxgyyg4mlvv31.png?width=1920&format=png&auto=webp&s=98707a2d9e4f531e97eacb9e5588327dd702bc14

    Not only that, but if I try to set a larger divider (which I don't want, but just to try it out), I get the extra shadows of the button there (shown on device too, not just on IDE) :

    https://preview.redd.it/7ifk1kjplvv31.png?width=704&format=png&auto=webp&s=e5d6d00c66e6c40796ba88559d612251be7c9214

    I know I can just use a normal TextView with a background that looks rounded in the top corners, but then it will lose the shadows around

    Is there a way to keep shadows of the button around and also have ones for the divider, while also seeing it all together?

    My wireless gamepad doesn't work on my phone(Galaxy A70) with OTG Cable

    Posted: 31 Oct 2019 09:52 AM PDT

    I own the Logitech F710. I bought a new otg cable. When I plug the gamepad receiver into the OTG, the phone detects the gamepad. But none of the buttons I pressed work on the phone. I also have the Logitech F310 and a cheap gamepad, which I tried on both of them, and it worked smoothly. Why am I having this problem with the F710?
