    Need ideas on how to make a basic icon for your app?

    Posted: 01 Dec 2018 08:34 AM PST

    I've been working with my app icons lately (I recently redid the icons for my 6 apps to get them to work with Android 8.0) and wrote about my process: http://www.amandafarrell.com/2018/11/making-basic-app-icons.html

    TLDR is that I use two layers: a background color and then a vector asset on top. Simple, scalable, and looks pretty good for someone like me whose only other graphic design skills involve Microsoft Paint. :P

    Hope that's helpful. If you know a simpler way, let me know!

    Constraint Layout and Magic/Pitfall of "0dp"

    Posted: 01 Dec 2018 12:48 PM PST

    Constraint Layout and Magic/Pitfall of "0dp"

    For only some particular cases, I have to switch back to normal layouts (Linear & Relative....).For a simple case where "ViewPager" is below the TabLayout and all other edges align with parent(screen edges), this "ViewPager" didn't work as it go beyond/above the "TabLayout" & "ToolBar" and same with bottom as it go out of the screen and hide under "NavigationBar" (hardware buttons).

    Why?Because, in ViewPager :- android:layout_height="match_parent", which is understandable as it specifies, but its not. I even trued "wrap_content" but didn't guessed it as IT MAY BE "0dp"(see below how i learnt it)

    ​

    When in a different situation, ScrollView is inside of "ConstraintLayout", same thing happened as "ScrollView" goes out of the screen (behind the hardware buttons, NavigationBar). This time it maintain to get below the "ToolBar".

    The "Lint" tool suggests "wrap_content" for ScrollView" contents, but it didn't worked and going back to "RelativeLayout". But somehow guessed and tried "0dp", and it worked.

    Then same applied to above situation and got success.

    Read somewhere that, for "match_parent" cases use "0dp" but I thought its only for "layout_width".Now, its true for "layout_height".

    State restoration done by Model in an MVP pattern

    Posted: 01 Dec 2018 04:08 PM PST

    I've been reading here about different approaches to model-view-presenter and one method is to let the repository serve up either cached or networked data in the model.
    DrinkRepository.java

    Map<String, Observable<List<Drink>> drinkCache = new HashMap<String, List<Drink>>(); public Observable<List<Drink>> fetchDrinks(String prefix, boolean useCache) { if (useCache) return drinkCache.get(prefix); return restaurantApi.getDrinks(prefix).doOnNext(drinkCache.put(prefix, Observable.just(listOfFetchedDrinks))); }

    BarActivity.java

    if (savedInstanceState != null) dataClient.fetchDrinks(prefix, true) else dataClient.fetchDrinks(prefix, false)

    DataClient.java

    Observable<List<Drink>> fetchDrinks(String prefix, boolean reuseValue) { return drinksRepository.fetchDeinks(prefix, reuseValue); }

    Assume DataClient is a singleton. It passes information from BarActivity to DrinkRepository to fetch cached or network data. If you're wondering why I don't fetch networked data if the cache doesn't have an observable, since DataClient is a singleton the values would be the same unless the user destroys the application.

    Am I understanding this approach? Doesn't this approach still rely on information from our activity (whether or not the device was rotated)

    With all the accounts being deleted, is it safe to move your app to a seperate account?

    Posted: 01 Dec 2018 02:55 AM PST

    I've read a lot of people having their account terminated for some weird reasons, partly because nobody in prison is guilty.

    ​

    Would it be safe to create a new account that would house a more important app? like a standalone account instead of one you use to publish all other apps.

    ​

    Update: so buying an app from another developer is a big NO-NO ? if they mess up their account you're fucked as well?

    Multiple dev accounts for the playstore questions

    Posted: 01 Dec 2018 07:03 AM PST

    I launched an app years ago on the play store. Long story short: I want to launch a number of apps under another name (or company name you could say). I've a few questions if anyone has done this before :

    1) Can you even have different company names for specific apps? Eg. App1 was made by company1, App2 was made by company2.

    2) Do you need to pay Google $25 again for every company name you have?

    A Quick Question

    Posted: 01 Dec 2018 01:45 PM PST

    Hi Guys,

    I'm looking to have an application built on Android & IOS. Let's say it would have simular features to Deliveroo. However I want the overall functionality of the App to be the same as on our future website. As in payment/functions/messaging/bookings/product lists and a few other things.

    In order for this to happen, does the App and Website need to be built off from the same backbone platform? Or can/should the App be built separately from the Website? E.g. Website on WordPress and App on Appery.io?

    I understand that 3rd party services like Stripe and say calender/schedulers can just plugged and in a synced with both. It's just the main site/app functionality that I want to be sure syncs and works in harmony with each other.

    Any feedback is appreciated. Links to sites with explanations is appreciated!

    How/where do I store a small set (35) of questions using SQL?

    Posted: 01 Dec 2018 05:19 AM PST

    I am creating a simple quiz app where a single layout and activity is used for displaying each question. The questions do not need to be updated/change so its a static set of data. How do I go about this? I was thinking of something like this. Is there any other better way?

    How to go about stacking/listing multiple fragments/frame layouts in linearlayout

    Posted: 01 Dec 2018 12:15 PM PST

    I have created a fragment that has some textviews and some buttons.I have a fragmentManager and a fragmentTransaction to add a fragment to a framelayout, located in main_activity.xml. If I make multiple fragements they stack on the same spot.

    ​

    Ideally I want to have fragment A, then fragment B below, followed by fragment C, etc., to scroll through. Suggestions on how to approach?

    Anyone success in using RoomDatabase.query to update sqlite_sequence table?

    Posted: 01 Dec 2018 11:59 AM PST

    I believe Room might have some undocumented restriction, to restrict us from updating sqlite_sequence table. As, when we tried to use RoomDatabase.query to update sqlite_sequence table, we fail to do so.

    I post the technical details right here - https://stackoverflow.com/questions/53573731/not-able-to-update-sqlite-sequence-table-using-roomdatabase-query

    Anyone has any idea on the correct way to update sqlite_sequence table, using Room? Thanks.

    There is no "Test Ads" label on AdMob ads at the testing devices for the release builds

    Posted: 01 Dec 2018 01:33 AM PST

    I am not seeing the usual "Test Ads" label on top of the AdMob ads at my testing devices anymore in the release builds. "Test Ads" label appears only in the debug builds. I double checked that my code for any changes done to lead this behaviour. But, i didn't find any.

    Is it happening to anyone else? Did AdMob changed it internally for the release builds? or Am i missing something?

    Update: It happens only in my Android 8.1 device. Rest of the devices are behaving normally.

    Does Android use some sort of cache to read MP3 file ID3 tags from?

    Posted: 01 Dec 2018 03:54 AM PST

    Hey there. So I've just come from a question I posted in AndroidQuestions, and the person helping me there had suggested I ask about my issue here.

    This is a link to my original question if you are interested, but I'll summarise it here with the relevant info.

    Basically, I've been having an issue where a certain artist's name tag in an MP3 file is being automatically changed on my phone to something incorrect.

    I used an MP3 tagging application on my PC to ensure the tags are correct beforehand. When I copy one of these songs onto my SD card, I can see in the file explorer that the artist tag has been changed instantly as it was transfered. So now the same file on both the PC and the phone have a different artst tag somehow.

    Any ideas what could be causing this? Does Android have some sort of cache that it is reading this data from, or could this be an SD card issue? It's possible my tags were wrong the first time I moved the files across, and now the old incorrect tags are being read from somewhere and applied. Any help is appreciated.

    I'm looking for some tutorials on how to code simple Android games.

    Posted: 01 Dec 2018 09:43 AM PST

    PSA: Material Design Guidelines have been updated to reflect iOS/Android-specific Bottom Navigation behavior, where on Android, clicking a bottom nav item resets to the top-level screen of that given tab (instead of retaining a backstack per each tab)

    Android Associate Developer Certification - what to focus on?

    Posted: 01 Dec 2018 06:16 AM PST

    I plan on taking the Android Associate Developer Certification Exam soon and I see that they also require now:

    - Paging Library

    - Testing

    - LiveData and Room

    Do they ask you to create an MVVM app with all of the Architecture Components? Also how important is the Paging Library? Thanks in advance

    Making app that interacts with a scale

    Posted: 01 Dec 2018 05:01 AM PST

    Hey,

    Ive been thinking about making my own fitness app lately and most of the features dont seem too daunting to take on. I have a problem though, and I cant seem to google myself to a solution, or find anything on here. So if Im just bad at searching, I apologize!

    What I want to do is, be able to connect my app to a scale, in order to read the input of the scale directly into my own app. I cant seem to find any tutorials on it, or potential scales that would be more open to this than others.

    Thanks in advance!
