    Effectiveness of the Weekly Questions Thread

    Posted: 28 Feb 2018 12:56 PM PST

    The weekly questions thread seems to have some questions that don't get any responses. It seems like StackOverflow's bounty program is one of the few ways to get some kind of response on a question. Another thing that has worked for me is asking questions in the android-united.slack.com and androidchat.slack.com slack communities. Does anyone else have effective places to get help on specific programming questions? I used to use the Google+ community (https://plus.google.com/communities/105153134372062985968) for this purpose but Google+ seems to be plagued with spam and useful responses are hit or miss.

    How to programmatically check if user has increased their display's “zoom” level via the Display/Accessibility settings?

    Posted: 28 Feb 2018 10:15 AM PST

    I am trying to rearrange a layout based on whether or not the user has altered their display "zoom" level in the android Display/Accessibility settings.

    I have tried using the following code:

    float scale = context.getResources().getConfiguration().fontScale; float density = context.getResources().getDisplayMetrics().density; float densityDpi = context.getResources().getDisplayMetrics().densityDpi; float scaledDensity = context.getResources().getDisplayMetrics().scaledDensity; float width = context.getResources().getDisplayMetrics().widthPixels; float height = context.getResources().getDisplayMetrics().heightPixels;

    Although, the above code does return the CURRENT display values, it does not indicate whether or not these values differ from the default values of the device settings.

    As an example, for a Samsung S7 Edge I get these results from the above code:

    Screen Zoom set to Small -

    scale: 1.1 density: 2.625 densityDpi: 420.0 scaledDensity: 2.8875 width: 1080.0 height: 1920.0 Screen Zoom set to Default -

    scale: 1.1 density: 3.0 densityDpi: 480.0 scaledDensity: 3.3000002 width: 1080.0 height: 1920.0 Screen Zoom set to Large -

    scale: 1.1 density: 3.375 densityDpi: 540.0 scaledDensity: 3.7125 width: 1080.0 height: 1920.0

    Let me know if anyone has any information for resources that can help me out. Thanks.

    [Question] Android Alarm APIs

    Posted: 28 Feb 2018 09:51 AM PST

    I had been tasked with developing an alarm app. Something simple which lets users set an alarm at a specific time and select a music file that should play when the alarm goes off. The app works great on phone like Samsung, Motorola, and Nexus but on Xiomi, Oppo, Vivo phones the alarm does not go off at the correct times and sometimes it does not fire at all. I have used Android's AlarmManager APIs. I am wondering if there is something else I need to do to get the alarm to work as expected on devices like xiomi, oppo, and vivo. Most of the solutions on StackOverflow have not worked out for me. If there are devs here in this subreddit who have worked with AlarmManager APIs before or worked on Apps with Alarm features, id really appreciates some more insight into AlarmManager APIs and why they don't work as expected across all phones and if there are any alternatives I should be using.

    How do you build Picasso from source?

    Posted: 28 Feb 2018 01:59 PM PST

    Feels like I'm missing something obvious. I have cloned the Picasso repo and switch to the 2.5.2 commit (6930ff127ed59bb8a51d4fcd9a836514922b8c00). However at that point it does not seem to be using Gradle. What are they using to build?

    What is the difference between the 'Profile' button and 'Run' button in Android Studio?

    Posted: 28 Feb 2018 02:13 AM PST

    The app can still be profiled with Android Studio's profiler even I click the 'Run' button to compile the app, so what is the difference?

    How can I edit my apps and fix bugs without updating it through the google play store?

    Posted: 28 Feb 2018 04:05 PM PST

    I have heard about this, I think it is called hotfix or patching, but i'm not sure how to do it, there is libraries such as Amigo and robust, but no good English documentation for it.

    How do you feel about integrating analytics into more robust architechtures?

    Posted: 28 Feb 2018 05:26 AM PST

    I'm currently using Clean in a project that now needs to have some analytics. I'm following the rules of the architecture, with an AnalyticsRepository and one use case for each tag/event and it works, but now I'm thinking it may do more harm than good. It is common that the customer asks for me to track some pretty unrelated info (in my point of view at least), coming from the view and different repositories and I now have more analytics related use cases than real business logic ones. The effort to maintain them is also bigger. There is never any return value, the calls to the analytics lib look and act a lot more like logging than service calls. I'm thinking maybe for this type of thing it would be smarter to just use functions to group the values and send. Leaves no room for error, nothing to lose. Or am I overlooking something? What are your thoughts? Thanks

    Using Rxjava for Bitmap manipulation

    Posted: 28 Feb 2018 05:26 AM PST

    Hi, I'm relatively new to Rxjava. I'm trying to create a bitmap in a background thread in an Activity so that my onCreate doesn't get blocked for too long. The code I've come up with for doing this goes like this:

    Single.create((SingleOnSubscribe<Bitmap>) emitter -> { try { Bitmap bitmap = Util.getQrCodeBitmap(CryptoWalletActivity.this, cryptoWallet.getAddress()); emitter.onSuccess(bitmap); } catch (WriterException exception) { emitter.onError(exception); } }).subscribeOn(Schedulers.computation()) .observeOn(AndroidSchedulers.mainThread()) .doOnSuccess(bitmap -> qrCode.setImageBitmap(bitmap)) .doOnError(Timber::e) .subscribe();

    This code is called in a function that is called on the main thread, after the Activity's onResume.

    I had hoped that this would cut down the ~3 seconds that it took to open this Activity, but that doesn't seem to be the case. Am I doing something grossly wrong here, or optimising for performance in the wrong place?

    Looking for help identifying where a notification sound is kept in an APK

    Posted: 28 Feb 2018 02:16 PM PST

    Sorry if this doesn't fit with the sub but I don't know where else to ask and I feel as though people here may know how to help.

    I'm trying to replace the default snapchat notification sound with my own and I'm looking through the APK with no luck right now. There's nothing which stands out to me as being the sound file I can replace.

    Any help would be much appreciated.

    Android app screen flickers in Huawei M3

    Posted: 28 Feb 2018 04:00 AM PST

    I am lost. I would really appreciate any ideas regarding my issue.

    Client bought Huawei M3 tablets and set display size to "small" is settings. Because of this my developed application sometimes starts flickering at random moments for a few users. All other applications work just fine. If user sets display size to "normal" then issue disappears.

    Any ideas what could be going wrong? I have no clue at what should I start looking.
