    How are you binding views in Kotlin?

    Posted: 29 Jan 2018 11:38 AM PST

    I'm finally starting to convert my code to Kotlin, and I'm curious what method people are using for binding their views. Kotlin Android Extensions? Kotter Knife? Something else?

    Searching for: Broadcast audio streaming for network mesh

    Posted: 29 Jan 2018 04:18 PM PST

    Hi, I know it's a little difficult to fulfill my request, anyway I'm searching for a library that could adapt to my goal to have a Push-to-Talk room over a network mesh, so with a network of devices that work as sender/receiver/bridge over WiFi (and if possibile also mixed with bluetooth). The closest thing I found is Bridgefy, but may I could get even closer?

    Sound Match API

    Posted: 29 Jan 2018 01:39 PM PST

    Hi,

    I'm thinking about the possibilities of creating an app that would use the phone's built-in microphone to record sounds and match those with a sound in a database (in whatever the most convenient format is).

    In my understanding this is fairly complicated since an app like Shazam matches the digital signature/fingerprint of already known music and therefore filtering out the ambient sounds is easier (my understanding is very limited).

    Now, I have experience as a developer and was (naturally) wondering if there is an API of some sorts that takes care of the matching since I am not a audio engineer. Is there anything publicly available to match recorded sounds with existing samples? Maybe even deal with background noise and other aspects I am not aware of yet?

    Ideally this would do all the labour and creating a simple app would be left to the developer. Maybe the reason I can't find any API's is that it's insanely difficult?

    Thank you.

    ShieldAuto gradle plugin for better proguard management

    Posted: 29 Jan 2018 01:23 AM PST

    Recently I was about to release a new project and was tired of googling each libraries for proguard configs. Some were outdated, some were overly bloated, and I thought maybe there could be a better way.

    🛡️ ShieldAuto! is a Java based Gradle plugin to manage proguard config for release builds.

    I hope some of you guys might find it helpful. I am planning for much more features and configuration options in the following months.

    Feedback/issues/pull requests are highly appreciated!

    Understanding Firebase Realtime Database Security Rules

    Posted: 29 Jan 2018 12:04 AM PST

    Security Rules in the Realtime Database always seemed daunting to me, mainly because the documentation was just so comprehensive.

    I decided to fix that for other people by making a tutorial that simplifies it greatly! https://www.ericdecanini.com/2018/01/27/understanding-firebase-realtime-database-security-rules/

    Copying a zipped Project from a PC with internet to another PC without internet

    Posted: 28 Jan 2018 07:32 PM PST

    Good day to all.

    I would like to ask if it is possible to open a "zipped project from a PC with internet (which can download the SDK present in google repository and note that the zipped project has the latest support libraries written in its gradle dependencies)", to another PC without internet?

    Is the zipped project will contain all the support libraries that are written in its gradle dependencies? Since Google has opted that the large sdk will no longer be downloaded to the PC.

    I hope that my question makes sense. Any answer will be much appreciated.

    Thank you very much.

    What are lock screen widgets/notifications with buttons called?

    Posted: 28 Jan 2018 06:26 PM PST

    It's been a few years since I developed an android app. I can't remember the name of the widgets/app/notification that exists on the lock screen but has buttons that you can interact with. For example, a podcast player has play/pause/stop buttons on the lock screen, Aquamail has a drop down with options to mark a message as read, etc.

    Basically I want to add a few buttons to a lock screen and log some data.

    What is that called? Is it a widget? a notification? The android version targeted is somewhere around 5.0 and above.

    If you happen to know of any good example code, that is great....but really I just need the name to know where to research.

    Thanks!

    Google Play collects crash information on debug versions too?

    Posted: 28 Jan 2018 10:56 PM PST

    Hey guys,

    I have noticed that when I debug my app and test new versions of it on my physical device, google play thinks that it's a for-release-app that is install on my device and it includes all crash information in Android vitals. Because of that I got greater than bad behavior threshold for Excessive wakeups and Excessive Wi-Fi scans (background), both of which were 0 before that.

    What can I do to prevent it from happening again?

    Can't see any text in AS 3.0.1

    Posted: 28 Jan 2018 10:55 PM PST

    See pics:

    I just downloaded Android Studio 3.0.1 (~750MB) from Google's android development site and installed according to the instructions they gave for Linux.

    I'm running it on Linux Mint XFCE with 4GB ram. I installed all i386 dependencies and also installed the default openjdk 8. I tried restarting the pc and still cannot see any text right from the starting screen. All the dialog boxes, buttons, etc have no text in them like in picture. Tried searching stackoverflow but all I saw was about text fields etc. Also searched Google for bugs etc but did not find anything related to this.

    Edit: I also tried different themes and changing system fonts to see if any of it was the cause and still cannot see any text. Also tried deleting AS 3 folder and running the AS installation script again. No change. :(

    Edit: Solved: I deleted everything, extracted the folder again from the zip/tar file and ran the script. Now i can see the text perfectly.

    Question about Designing Hawaiian Checkers game in Android Studio

    Posted: 28 Jan 2018 08:08 PM PST

    Hi so I've been trying to make the game Konane (hawaiian checkers) In Android Studio with 0 experience in it, and I've come to a bit of a roadblock regarding the movement of pieces.

    Before I get into that here are the rules:

    The game begins with all the counters filling the board in an alternating pattern of black and white. Players then hop over one another's pieces, capturing them similar to checkers. The first player unable to capture is the loser; his opponent is the winner.

    https://gyazo.com/e01443d09f75df1a764842c98a220a09

    The link above is pretty much all I have right now.

    Right now Instead of having pieces I am just using buttons and I want to be able to click them and click on a blank space and execute the move, removing the piece inbetween and moving the original piece to the blank spot.

    I was wondering if anyone could offer any advice on how I can do this; I don't have much experience with Android Studio or Java really and am pretty stumped as to how I should do this.

    Thank you!
