    Securing Data Storage in Preparation for Pentesting

    Posted: 13 Mar 2020 05:01 AM PDT

    Someone stole my app and modified the code a little bit and uploaded it to the PlayStore. What action should I take? In order to take that app down?

    Posted: 12 Mar 2020 10:20 AM PDT

    Admob and Play store will not disable or terminate your account if your app makes more money for Google

    Posted: 13 Mar 2020 08:10 AM PDT

    This app and their store are strong violent Play store policy and so greedy when showing Ads when you click back button to exit the app. But I don't know why it isn't removed on Play store and Admob doesn't handle this. Seems no fair between developers here.

    How do you manage app updates that rely on new web service versions with breaking database changes?

    Posted: 13 Mar 2020 05:44 AM PDT

    So we have app version A which relies on web service version 1 and the new app version B which should use the new web service version 2. No problem so far, both can run parallel.

    But what do you do if version 2 of the web service has breaking database changes which won't allow web service 1 to work anymore.

    Why did we choose two different parallel web service versions anyway? Because we want to make sure, that users who haven't updated from app A to app B can still use the app, even if web service endpoints have changed in the meantime.

    So, is this a common problem? How do you manage it? Or what alternative approaches do you use in order to not break old versions of your app?

    Should I abandon ObjectAnimator for Motionlayout

    Is it possible to create a Custom View Base class? Especially when a custom view inherits either View, Button, ConstraintLayout etc.

    Posted: 13 Mar 2020 04:20 AM PDT

    Seems hard to do as the custom view class would have to be a abstract class to get rid of the constructors.
    So when we previously had class CustomView: ConstraintLayout
    I now want to have something like:
    class CustomView: BaseView<ConstraintLayout>

    unfortunately it seems like Kotlin doesn't allow extending generic types, which would have been the solution here so
    abstract class BaseView<V: ViewGroup> : V

    Is not possible, any other way that you can achieve something like this?
    As I said the constructors and inflating are always the same, but the subclasses still need to inherit from other classes as well.
    I know multiple inheritance isn't supported but there should be a solution to this :/

I see behaviour issues, I never had on any of the Pixels.Yeah, I could buy multiple devices from different brands, but well how should I fix specific issues, with some device name/brand checks in my app?I would appreciate any help on this topic.

    Mastering UI development

    Posted: 12 Mar 2020 01:15 PM PDT

    Through my professional mobile developer journey I always had some kind of UI / UX designer as a part of a team, or designs were already provided by client. I barely develop UI myself. For personal projects I usually use built-in material components and adjust colors. Still, apps looks very generic.

    Additionally, some time ago, during pair programming session (which was part of recruitment process) I had to draw triangle on canvas. I just copy-pasted code from SO and adjusted it for some obvious performance reasons such as "don't allocate stuff in onDraw() method". However, for me that was the most challenging part of recruitment assignement.

    I feel preety comfortable creating all kinds of Android SDK agnostic app logic, debugging weird Android issues or using standard APIs. I'm not sure how I should develop myself in UI field. Sometimes I feel, that I should re-learn everything and start from scratch.

    Do you have any experiences in similar situations? What are your recommendations? Maybe I should take some graphic design classes?

    How to Sign BUNDLE to upload

    Posted: 12 Mar 2020 11:33 AM PDT

    Hi!

    I always worked with APKS, never with BUNDLES, and I always used the same file to sign the APK and upload it to the store. Currently, I think, I have to upload a BUNDLE. I do the same signing process as the APK, with the same file that I used to sign the APKS but when uploading it to the store it tells me that it is not signed.

    ​

    Any idea?

    Has anyone been able to get their AS 3.5 debugging on device to not totally suck?

    Posted: 12 Mar 2020 11:06 AM PDT

    I'm just finding it to be barely usable performance-wise. Are there any settings to tweak that would improve this? I'm apprehensive to go to 3.6 as each release it's been getting worse.
