    Android 10: “tile memory limits exceeded, some content may not draw” Multiple WebViews inside my app

    Posted: 02 Aug 2020 02:58 AM PDT

    Since one or two weeks some ads inside my app wont show up and would just flicker! Its random when this happens, and it flickers continuously

    I have banner ads and video ads in my app and thats the way i call them:

    holder.wv.setInitialScale(1); holder.wv.setLayerType(View.LAYER_TYPE_SOFTWARE, null); //i call that on banner ads, stackoverflow fix holder.wv.getSettings().setJavaScriptEnabled(true); holder.wv.setBackgroundColor(Color.argb(1, 0, 0, 0)); //stackoverflow fix holder.wv.getSettings().setUseWideViewPort(true); holder.wv.getSettings().setLoadWithOverviewMode(true); holder.wv.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY); holder.wv.setScrollbarFadingEnabled(false); //loadurl etc

    I already googled a lot and found out that the hardware acceleration might be problem so I am turning it off for the banner ads but for my video ads i cant because otherwise they wouldnt work

    My ads are integrated in a Recyclerview that loads a CardView with the Webview inside. I have 4-5 on each site but there were no problems with the amount of ads, never. There must be kind of issue with the Webview or the Chrome Driver itself? Thats what came up when I searched for my problem

    Does anyone encountered this problem?

    E/chromium: [ERROR:tile_manager.cc(793)] WARNING: tile memory limits exceeded, some content may not draw

    Any issues with Android Studio/native NDK development workflows if one updates to MacOS Catalina (which only allows 64-bit code to run)

    Posted: 02 Aug 2020 01:29 AM PDT

    MacOS Catalina is the first mac os version that is going to stop supporting 32-bit code - only 64-bit programs/libraries will run.

    My question is whether any of the android developer (Android Studio/NDK compilation) workflows are going to be affected by this ?

    Are there any components there that are still 32-bit and may fail on MacOS Catalina?

    Is Android development difficult to learn?

    Posted: 02 Aug 2020 08:16 AM PDT

    I plan on starting 30 days of code challenge!

    1. Would I be best off learning Java or Kotlin? (Kotlin looks interesting to me)

    2. What are some of the best resources for app development? If I'm going to do the 30 day challenge, should I build a small app everyday? In addition, is it worth getting the Google Associate developer certificate?

    Don't use email magic link for auth...

    Posted: 02 Aug 2020 12:17 AM PDT

    When we considered user auth methods, we first looked at using only using "Sign in with Google/Facebook". However, App Store guidelines now require that any "app that use a social login service ... must also offer Sign in With Apple as an equivalent option" -- which means you won't be given the true email of most users (given Hide My Email) ... so if you're developing X-Platform, simply using Google & Facebook is no longer viable.

    Given we wanted to allow users to find other users on the app, we needed a unique user identifier per user, giving us 4 options:

    1. Email + Password ... requires forgot password and users to prove email ownership
    2. Support all third-party (Apple, Google, Facebook) ... and add a new unique identifier to allow friends to find each other, given email will not be sufficient
    3. Phone number magic link ... we were relying on Expo (previously did not support phone-number auth), and we also felt emails would be a good/cheap tool for communication
    4. Email magic link

    Email magic link felt... perfect, but it was pretty much a disaster, and you should be pretty wary of doing it without implementing safeguards. I imagine email + login code is a better option.

    Here are the various safeguards we tried with metrics and graphs: https://snaphabit.app/blog/password-less-login/. Happy to answer any additional questions!

    ViewSwapper: a new library for single activity architecture fans

    Posted: 01 Aug 2020 10:31 PM PDT

    Self plugging here for a recent library I made:

    ViewSwapper is a simple view container (think like FrameLayout) that supports transitions (API level 19+) and can be used to swap out screens without having to bother with fragments: https://github.com/grant-park/ViewSwapper

    it's meant to be a convenient basis for UI in any MVU/MVI apps, but also great for anyone who needs some flexible and lightweight view replacement

    would love to start some discussion and answer any questions regarding this or single activity

    As senior Android dev, how hard/time consuming is it to learn Spring/Hibernate for BE development?

    Posted: 01 Aug 2020 10:36 AM PDT

    Just something that's been on my mind for some time. I'm sure I'm not the first one.

    I've been doing Android development for nearly 5 years now, currently working as platform lead. I actually still like the platform (although it's not perfect) and write code regularly but was thinking about broadening my skill set.

    Anybody here who's gone through this? And if you switched to a BE job, do you prefer it now?

    DIY gesture detection with DTWarp

    Posted: 01 Aug 2020 02:43 PM PDT

    I initially set out to write an app that required knock detection. From there the usual thing happened. I wasn't satisfied with what I found, so I decided to read up on dynamic time warping and write my own library:

    https://github.com/xep426/DTWarp-Android

    The project includes an example app that is available on google play. I wanted to make everything as intuitive as possible in order to get anyone up to speed and warping themselves within minutes.

    Since I haven't done anything similar before I 'm hoping to receive some feedback before I expand the scope to sensor management, classification, assisted learning and so on.

    Playing a Video with Jetpack Compose

    Posted: 01 Aug 2020 11:12 PM PDT

    Subscriptions getting declined every time after trial ends. Anybody facing similar issues?

    Posted: 01 Aug 2020 04:58 PM PDT

    Most of my subscribers, after trial ends, go into "Payment pending" and then "Payment declined". Those are mostly USA users. Anybody knows why this is happening? Is so frustrating, on trial it says that the payment method has been verified, but then it always fails. Any idea why this is happening? Solutions?

    Kotlin way of building RecyclerView Adapter �� `Kiel`

    Posted: 01 Aug 2020 12:14 PM PDT

    Most of time:

    • We found ourselves repeating same boiler plate codes for RecyclerView.Adapter
    • We have difficulty in handling RecyclerView.Adapter
      when there are many viewTypes

    But now, Kiel may help us to get rid of these problems.

    https://github.com/ibrahimyilmaz/kiel

    Kiel is a `RecyclerView.Adapter` Library with with a minimalist and convenient Kotlin DSL which provides utility on top of Android's normal `RecyclerView.Adapter`

    All of feedbacks and reviews are greatly appreciated!
