    Hi guys, I am 16 and I created an open-source app that reminds you to wear a mask when you leave home (or any chosen location)!

    Posted: 27 Sep 2020 04:37 AM PDT

    As the title says, I am a 16 year old high-school student that has been developing for android for the past year. I've created an app called wearAmask for android that reminds you to take your mask whenever you leave your home, work or any other location.

    wearAmask works by allowing users to add a location (address) on a map by holding down on the map or typing an address. Once you choose a location, you can select the radius of the region, choose a color and enter a location name.

    Once you enter a location, or even many locations if you'd like, wearAmask will automatically run in the background and will remind you to take your mask whenever you leave that location! (and also reminds you to take necessary precautions).

    The app is currently open to public testing and is 100% free, no ads, completely open source and no BS whatsoever :)

    wearAmask on Google Play and also for anyone that wants to check out the code, it's on GitHub here

    Oh and I also posted this on r/androidapps but wanted more technical advice and suggestions based of the code itself.

    Would really love to hear feedback from you guys! Any code improvements, suggestions and bugs would be really helpful!

    Also here's a cool promo video I made for the app if you'd like to have a look!

    Fragment blink

    Posted: 27 Sep 2020 04:15 AM PDT

    I'm having a problem when I try to show a fragment from an activity. The fragment is showing well, but with a blink effect. I could see the blink effect is because it's showing the fragment and then it's showing it with the transition I set it up before on the activity, it's too fast but I can appreciate it. Is there a way to fix this problem?

    How controversial would it be to have a mobile game that has a person as app icon, but the race of this person being localized for different languages? (i.e. white person = English, Asian person = Korean)

    Posted: 27 Sep 2020 06:21 AM PDT

    Google allows you to localize app icon based on language - what if you localized the race of the person in the app icon based on the majority race that speaks that language?

    Would this be controversial? If data confirms that Asian market would click more on the app icon if it showed a person of their race, as opposed to a race that doesn't speak their language, would there be anything wrong with moving forward with such localization?

    Is it normal for Android Studio to create so many processes?

    Posted: 27 Sep 2020 05:00 AM PDT

    Android studio quickly becomes unusable for me. I don't even have many things in my simple project, it was just started and only has about 3 very simple fragments working now. I built and ran the project three times now on a physical device and as you can see the whole ram has been filled.

    I even switched over to a jdk that uses open j9 thinking it would reduce memory consumption but nope.

    Attaching images since I have no idea how to get a text from this:

    Htop1

    Htop2

    Htop3

    (No other apps were running on the system, it was just Android Studio)

    u/vzzz1, has noticed that there are too many Gradle and kotlin compiler processes

    Redmi 6A Android 9 help needed

    Posted: 27 Sep 2020 03:15 AM PDT

    Hi,

    I had formatted sd card as internal/adoptable storage (ext4 file system format I guess) about a week ago. It was working fine except sometimes it got stuck and I had to reboot the phone and the card storage would work fine again.

    Now the sd card has stopped showing in storage settings and phone's internal storage is also not showing in file mangager. all of my apps are stuck and I am unable to recover data from sd card or access my phone's internal storage. I have tried restarting phones and put the card into other phones but it just won't show up in storage or anywhere else. Even using list-disks and list-volumes commands in adb shell won't show any result. Please help as I have very important data in that card. Regards

    Can android apps send specially-crafted ARP packets?

    Posted: 27 Sep 2020 01:10 AM PDT

    This is probably going to sound very dumb, because I'm fairly new to android development (it's basically just a hobby for me). Regardless, I was wondering: is it possible for my android app to send specially-crafted ARP packets?

    Isn't Google "blocking" the UI in this sample?

    Posted: 27 Sep 2020 12:38 AM PDT

    https://imgur.com/a/YIPJ6tX

    This is from Google's Architecture Blueprints V2 sample. I'm particularly interested in the _taskUpdatedEvent at the bottom, which triggers the back navigation in the fragment. They navigate back from the screen after the insert operation is finished, inside the coroutine. Isn't this pretty similar to blocking the UI thread? It won't freeze the UI, but you can't actually do anything on that screen until the operation is finished and it's not really necessary to not navigate back immediately. I know that this operation will only take a few milliseconds but still, there is a reason why we execute queries on a background thread in the first place. Also, this operation could take longer if something changes behind the scenes.

    Edit: createTask and updateTask are suspending functions

    Where's the option to upload deobfuscation files in the new play console?

    Posted: 26 Sep 2020 01:25 PM PDT

    So I just uploaded a new APK to play store, and it's telling me to upload the deobfuscation files. I know where I can upload those in the old console, but I'm unable to search it in the newer version, and I've spend like 20 minutes searching for it.

    Anyone know where I can find it?

    xmlns:android="http://schemas.android.com/apk/res/android"

    Why does this do? :(

    Totally new to android dev (irdk if this even counts as android dev). Im taking this course on udacity but i cant really ask doubts on the platform cuz im not a member or w/e... N i didn't really understand the reason for the usage of the line... Except for the part where she said something about namespace but i didn't get the significance of it.

    PS. Do tell me if i haven't/have phrased my question well enough or if i need to change something. Thanks a lot!

    When to bring an iOS app to Android?

    Posted: 26 Sep 2020 01:02 PM PDT

    I own an iOS app with a modest userbase and am debating whether to port it to Android. My target demographic is more likely to use iOS. It's tempting to make my app available to Android's much larger audience, but I don't have a compelling reason beyond that. Are there any "rules of thumb" about when it makes sense to create an Android version of an existing iOS app?

    Also, I plan to add in-app purchase functionality to my iOS app. Would this make it more difficult to port my app to Android later on? Would it be best to not implement IAP until I'm on both platforms?

    [Help]

    Posted: 26 Sep 2020 11:42 AM PDT

    Whenever I try to run my app (the emulator is working fine) my event log is getting spammed with the following error messages:

    20:39 'C:\Users\XXXXX\AppData\Local\Android\Sdk\platform-tools\adb.exe start-server' failed -- run manually if necessary 20:39 * daemon not running; starting now at tcp:5037 20:39 adb: CreateFileW 'nul' failed: The system cannot find the file specified. (2) 20:39 * failed to start daemon 20:39 error: cannot connect to daemon 

    I tried downloading new adb kits from adbshell without success. I tried killing all adb processes, no success. Tried reinstalling whole android studio and everything included and restarting my pc, no success.

    The Emulator is working fine though, I just can't get to run my app. I'm running an AMD Ryzen System if that matters.

    GPS App Coding Question

    Posted: 26 Sep 2020 10:01 AM PDT

    Basically I want to track my phones location from my computer by installing an app on my phone that is linked to another one on my computer. How would I go about learning more about this type of software design? I also want the app to be able to turn the gps on and off as a way of "communicating" with the computer.

    I am not to familiar with GPS so if anyone has any input or can point me in the right direction that would be great.
