    Jetpack Compose 0.1.0-dev09 is released

    Posted: 16 Apr 2020 12:45 AM PDT

    Release notes:

    Other than these, the most interesting stuff is that they also added RxJava and LiveData adapters for Compose. Here are some examples

    There is an open issues for adding Kotlin coroutine Flow support as well so I suppose we can expect an adapter for that soon.

    Why more than two android flavor dimensions don't work properly?

    Posted: 16 Apr 2020 05:50 AM PDT

    There is a powerful mechanism in Gradle for android that allows the developer to create application flavors and split code, configurations and override resources. I use it in more than two years in different applications, but all that time I had only one or two flavor dimensions. Today I tried t add the third dimension to my project and still can't build it.

    Here is a problem, for example, I need the next three dimensions for my app: "brand", "environment", "market". The configuration will look like this:

    flavorDimensions "brand", "environment", "market" productFlavors { // brand nike{ dimension "brand" applicationId "com.android.nike" } adidas{ dimension "brand" applicationId "com.android.adidas" } // environment dev{ dimension "environment" applicationIdSuffix ".dev" } prod { dimension "environment" } // market google { dimension "market" } amazon { dimension "market" } }

    As a result, I can build the next 8 applications (I ignoring build types in this example):

    nikeDevGoogle nikeDevAmazon nikeProdGoogle nikeProdAmazon adidasDevGoogle adidasDevAmazon adidasProdGoogle adidasProdAmazon

    As I understand documentation about flavor dimensions, application nikeDevoogle use files from the next folders: main, nike, dev, google, nikeDev, nikeDevGoogle. But it doesn't work, Android studio sees only files in main, nike, dev, google, and nikeDevGoogle. Files in nikeDev ignored and even doesn't mark as currently active.

    Does anyone know why it happened? Am I missing something?

    P/S/ Sorry for my bad English, I suppose you understand my main thought

    Refactoring an old app

    Posted: 16 Apr 2020 05:57 AM PDT

    I am wondering if there is any solid advice for refactoring android apps. My company inherited a project and the clients app is very very buggy and unstable. The code is in java/MVP - but they didn't use the presenters to do anything other than make HTTP requests and hand that data to the activity/fragment. The activity/fragments are gigantic and have tons of business logic in them. The application class is also bigger than any of the ones I have written with tons of services instantiated and managed there. Dagger present - but not injecting anything. A lot of libraries in the gradle file that aren't being used. Null Pointer Exceptions everywhere due to life cycle stuff. I can't really say more than that - but where do you start for this type of refactor where throwing everything out is not an option.

    Posted: 16 Apr 2020 06:14 AM PDT

    I've been out of touch on multidexing lately, is it still a thing for minSdk above 21? How about methods counting, are we still counting, if yes, how?

    How to keep your app rating in Google Play high ��

    Posted: 16 Apr 2020 08:18 AM PDT

    Why stars matter

    There are a lot of articles about things that affect your app positions in the store. Each one of them has a rating on the list and it's totally logical. The more positive ratings your app has the more potential and trust it gets from algorithms. It automatically seems like a lower risk to suggest it to app store visitors. So it's crucial in ASO to keep it high as it affects your rankings and conversion.

    The question here is how to work with it.

    ❗️Disclaimer ❗️ The major part here is the app itself. If it's objectively bad no ASO, ads, and other out-app activities won't change it.

    Ratings

    Don't forget to request it from your users. The possibility that a user will get back to your app page in a store and leave the rating there is looow. So just add requests to leave the rating right in your app.

    Stores advise you to be careful with it and follow simple rules:

    • Wait for it. Don't ask to soon and give your users time to click-through your app;
    • Hit when it's hot. Find the perfect timing for the request. For example, it can be shown after the completed level in a game or action in an app.
    • Don't spam. Make the pause between two shows so the user won't get bothered.

    ⚡️ Bonus for Google Play. If a user left a low rating you can open the support ticket instead of sending it to the Google Play.

    Reviews

    Things get serious here as everyone can see the reviews to your app and unlike the rating, it's way more detailed. The few things to remember when working with reviews:

    • No ghosting — answer to each and one of them. Use the reply opportunity to make users change their negative review to positive. And ask to recommend your app to friends and colleagues when answering positive ones.
    • Keep it updated. If it was about the bag and you fixed it, mention ii in the answer so your app page visitors wouldn't be worried.
    • Don't tolerate spam. If a review is irrelevant or spammy, make sure to send it to app stores support so they delete it.

    A tool to simplify it

    We at Checkaso understand that rating and reviews analyze is a must. And we just released the Rating and reviews tab to simplify it for you. You can analyze ratings and reviews of your app to find the ways to grow it. It has awesome filters like the app version. data period, and status. You can learn more about it on our blog and please feel free to try it/leave your feedback or share your view on the rating situation. Thanks!

    Open a drawer from a fragment or another fragment?

    Posted: 16 Apr 2020 08:11 AM PDT

    Open a drawer from a fragment or another fragment?

    I have an app that uses a main activity and at the moment 4 fragments, on one of the fragments is a school calendar with events, this also need to have a search function where they can search through all the events of the year. This used to be an another app where the calendar and search where separate activities, but now I have to merge it into a master school app. What is the best way to have the search function belong to the calendar fragment.

    This is the current design for the calendar fragment, I was thinking a search icon on the toolbar but the thing is since the search used to be a separate activity, and this is now a fragment I don't know how to implement it, can a fragment be called from another fragment? or is there a another thing I could implement that would look nice and be functional?

    ​

    The bottom of the image doesn't reflect all the view, there should be events there it's an emulator so they aren't showing up but it's a RecyclerView with events.

    Calling a fragment's methods from an activity

    Posted: 16 Apr 2020 07:28 AM PDT

    Every time i try to do this, i get the "non-static method cannot be referenced from a static context" error. What is the work around here? How do i access methods from other classes if either of them are static? Feel like i can't do anything...

    My fragment is declared

    public class Frag1 extends Fragment

    And my activity is declared

    public class MainActivity extends AppCompatActivity

    And my viewpager is declared

    public class ViewPagerAdapter extends FragmentPagerAdapter

    I had a similar issue when calling methods from code in Frag1. The workaround there was overriding the onViewCreated() method and writing my onclick listeners etc there.

    Android API version where app shortcuts are required to be supported by launchers?

    Posted: 16 Apr 2020 06:30 AM PDT

    I am developing an app where its main feature is to create pinned shortcuts.

    However, not all launchers support shortcuts. The problem is that since I cannot know this before the user installs the app, some users will get an error message that "Shortcuts are not supported by your launcher".

    Is there an API version (e.g. Android 10 - API 29), where all launchers are required to support shortcuts?

    I have an app idea that solves a common local problem, but I can't code or design. Any ideas? Also discuss what else could be in this app.

    Posted: 16 Apr 2020 06:15 AM PDT

    So my app idea is dependent on Google Maps, and some math.

    So, here's the concept. There is a friend group of X people, and they want to minimize the travel time to go to a gathering. So this app would choose a venue using specifications by the user (cost, type of venue) and mathematical optimization techniques (that I have yet to fully learn)

    It will be a while before I learn these, so I wonder what I should do for now. Should I have this patented or should I try finding people to help in making this idea into a reality?

    I just opened my game to Alpha and even updated it

    Posted: 15 Apr 2020 09:23 PM PDT

    I have spent quarentine building a game. It is going great, but I was getting slightly burnt out with the same project for so long. I especially hated waiting so long for it to be published, but it finally happened. I have received amazing feedback on bugs and insights! This is a huge help with the burnout. I already prepared and submitted an update to some major bugs (compatibility). I feel reinvigorated. I want to add all sorts of features, test them with my alpha team, and get this thing on full production.

    With other coding projects, I struggled with reaching a complete version of the project. I would start things and have lots of good ideas, but burn out made me move on. I won't let that happen with my first app!

    How is everyone else doing during this time?

    MotionLayout - Constraining off the screen

    Posted: 15 Apr 2020 12:34 PM PDT

    Hey guys, I am trying to mave an image resource float in from off the screen, but i am having problems defining the start position as off the screen; no matter what I do, Android Studio wants to make sure it's visible at all times.

    I have tried making a guideline off the screen (at the top) and constraining the bottom of the image to it, but having no luck. Here is my layout(initially doing the layouts in app:layout and then moving to motion:layout later):

    <androidx.constraintlayout.motion.widget.MotionLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/MotionFragment" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" android:paddingStart="10dp" android:paddingEnd="10dp" app:layoutDescription="@xml/motion_scene" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintEnd_toStartOf="parent" tools:context=".MotionFragment" tools:showPaths="true"> <ImageView android:id="@+id/cardView" android:layout_width="100dp" android:layout_height="140dp" android:contentDescription="@string/CardMove" android:elevation="4dp" android:src="@drawable/card_ah" app:layout_constraintBottom_toTopOf="@id/guideline" /> <androidx.constraintlayout.widget.Guideline android:id="@+id/guideline" android:layout_width="wrap_content" android:layout_height="0dp" android:orientation="horizontal" app:layout_constraintGuide_begin="-19dp" /> </androidx.constraintlayout.motion.widget.MotionLayout>

    And my motion xml scene file:

    <MotionScene xmlns:android="http://schemas.android.com/apk/res/android" xmlns:motion="http://schemas.android.com/apk/res-auto"> <Transition motion:constraintSetEnd="@id/end" motion:constraintSetStart="@id/start" motion:duration="1000"> <OnClick motion:clickAction="toggle" motion:targetId="@id/cardView" /> </Transition> <ConstraintSet android:id="@+id/start"> <Constraint android:id="@+id/cardView" android:layout_width="100dp" android:layout_height="140dp" android:layout_marginStart="8dp" /> </ConstraintSet> <ConstraintSet android:id="@+id/end"> <Constraint android:id="@+id/cardView" android:layout_width="@dimen/card_width_finish" android:layout_height="@dimen/card_height_finish" motion:layout_constraintBottom_toBottomOf="parent" motion:layout_constraintEnd_toEndOf="parent" motion:layout_constraintHorizontal_bias="0.24" motion:layout_constraintStart_toStartOf="parent" motion:layout_constraintTop_toTopOf="parent" /> </ConstraintSet> </MotionScene>
