    Where do you like to refresh your OAuth2 tokens?

    Posted: 04 Aug 2020 03:31 AM PDT

    Have seen various advice out there. I've been experimenting for a while with examples of OKHttp interceptors that reauthenticate unauthorized 401 requests. But I kept running into threading issues and had more luck with authenticate-in-advance. Wonder what your experiences have been like.

    How many people uninstall your app/game the same day they download it?

    Posted: 04 Aug 2020 04:02 AM PDT

    My third game for android has been getting a steady increase in active installations for over a month, but I noticed that around 2/3 of new installations end in an uninstallation in the same day. I believe that that number is pretty high, how many people install and then uninstall (in the same day) your app ?

    Am I supposed to mark my beer menu reader app as "promoting alcohol"?

    Posted: 04 Aug 2020 02:38 AM PDT

    1. Am I supposed to mark my beer menu reader app as "promoting alcohol" and thereby getting the "mature" rating? It doesn't really promote alcohol but at the same time it does refer to alcohol because the whole point is to take a picture of a beer menu and see the user ratings.
    2. How would such a rating affect AdMob ad revenue? I tested one ad in real life and it looked very abnormal; a very uncharacteristically plain gray background with no images leading to something that seemed like a dating site (I didn't click on it). It might even be interpreted as part of the UI of my app. I thought ads are supposed to be colorful and more, well, ad-like. Is this because of my "mature" content rating?

    Android Emulator performance issue (Ryzen 16 threads, 32GB RAM)

    Posted: 04 Aug 2020 05:53 AM PDT

    Anyone know how can I improve performance of Android Studio Emulator? It is really laggy and slow, no matter if I manually edit config.ini values and increase ram or cpu cores it can use, it is still slow on onPress events and keeps stuttering while scrolling. I think it is not properly utilizing GPU hw acceleration..

    I have Ryzen 3800X, 32GB 3200MHz RAM and Nvidia GTX 1070 8GB. Windows is clean and freshly installed. Android emulator is up to date also.

    How to do Material Transitions between Fragments in seperate Activities

    Posted: 03 Aug 2020 07:58 PM PDT

    Hello.

    I have been doing a lot of reading / experimenting with shared transitions.

    Specifically for activities using ActivityOptions.makeSceneTransitionAnimation() and for fragments using addSharedElement() on a transaction

    This seems to work fine for Activity -> Activity or within the same Activity (Fragment -> Fragment).

    However the case I cannot get to work is as follows. Activity A has a Fragment B which contains a recycler view. I want to transition when a view in Fragment B recycler view is clicked to new started Activity C which contains Fragment D where Fragment D has the actual content.

    So essentially a Fragment transition between an existing Activity and a new one starting up

    Had anyone had experience with this type of transition and can possibly share a code example? I have read a few posts which have claimed the above is impossible but wanted to check here

    Linux > W10, why and which distro?

    Posted: 04 Aug 2020 04:28 AM PDT

    Except security and its open source philosophy, why using Linux to develop on Android Studio is the best choice? I have seen on Youtube, Linux is faster to build the project (maybe 30% faster) but there is another interest to install Linux? just to save time? Or there is another real reason?

    And of course, what is your best distro only for Android development? (I saw in serveral posts, Ubuntu is the most popular here )

    Thanks.

    Has anyone had an app suspended recently?

    Posted: 03 Aug 2020 04:05 PM PDT

    Hey everyone. I'm a writer over at XDA Developers, working on a piece about the Google Play Store.

    I'm doing some research into Google Play's recent promise to make app suspensions more detailed. After reading that they were doing this, I attempted to get details on one of my older app suspensions, but they were still unable to tell me why it was suspended.

    However, that might be because it was suspended before this new policy, and it doesn't apply retroactively. If you've had an app suspended recently (since July 8), would you mind sharing your suspension notice? It doesn't need to include the app name or the package name. Just the violation and (if it exists) the exact reason for suspension are enough.

    Thanks.

    No POWER OFF on lock screen. [DISCUSSION]

    Posted: 04 Aug 2020 01:04 AM PDT

    For improved security against device theft.

    ​

    • It should be a feature of all android devices to not have POWER OFF & AIRPLANE MODE menu come up when long pressing the power button on lock-screen (if the device has password or pin set-up)
    • Only the REBOOT & SILENT option should be there on pressing button, when on lock-screen.
    • In most of the theft cases, first of all the device is powered off or put to airplane mode or the sim card is removed. (though it requires the ejector tool and in most new devices the battery is inbuilt so it can't be removed to power off directly)
    • Also in most new devices there is a feature to disable notification shade or status bar when on lock-screen.
    • So in this way the "Find my Device" will really be useful to locate the device if it goes missing.
    • After searching, I found a third-party app to do the same, BUT its very old and of-course 3rd-party.
    • So, any suggestions if this will be actually useful or not and the possible demerits of this feature.

    Head First Android Dev *VS* https://developer.android.com/training/

    Posted: 04 Aug 2020 12:47 AM PDT

    Which one do I choose? HF was published in 2015 and Android Studio version is clearly different. Besides that, I find Android Dev a very concrete thing, not like Design Patterns or Java basics that could be more acceptable to learn from an old book (I read those two from HF too).

    Is Android dev abstract enough to rely on a 5 years old book or should I go for the official guide to avoid deprecated practices? Or maybe I should do a different thing?

    Thanks for your help.

    Example of a runtimeOnly dependency

    Posted: 03 Aug 2020 04:51 PM PDT

    I'm reading up on Gradle build configurations and I understand the difference between implementation and compile. I also understand youd use compileOnly for a dependency that is only needed at the compile time. However, I can't seem to find a real life example of a runtimeOnly dependency. If the dependency isn't available at compile time, how do you even compile your project?
