    PeriodicWorkRequest (work v1.0.1) is spawning 20 times every 15m instead of just once, not sure why

    Posted: 07 Nov 2020 08:28 AM PST

    In the follow code excerpts, I am utilizing a BroadcastReceiver to start up a Service on device boot and/or package reload. This NotificationService is calling my Worker via PeriodicWorkRequest every fifteen minutes. Everything initially works as it is supposed to, until the NotificationWorker is executed. It seems that, at the point where the Worker is invoked, it runs twenty times instead of just once. I believe that is twenty times exactly, as well. After all of it is said and done, it waits for ~15 minutes, as it should, and then exhibits the same behavior when it again invokes the Worker. Ideally this Worker should only be run once every 15m, especially being as some of the computation that it will be doing is rather expensive.

    I have spent days now, googling for more information (I've partially been hampered in this due to using Work v1.0.1, instead of the more recent, androidx v2.4.0, but I'm not ready to upgrade everything that would be broken in my project with that change) and doing my best to debug this issue. Unfortunately, the debugging has been rather slow and unproductive, due to the fact that I can rarely get my Log.?() messages to even show up, let alone to give me any hints as to where this behavior is coming from. This behavior (Log messages not showing up) has been a problem in BootServiceStart, NotificationWorker, and NotificationService, and I've got no idea why.

    Here is the applicable code for the issue; please note that if you follow the dpaste links you will find the general areas of the problematic code highlighted in order to ease diagnosis a bit (dpasted code will only be available for 6 more days):

    BootServiceStart - also here on dpaste (https://dpaste.org/rLNJ)

    I would be very grateful to anybody who might be able to offer any insight on why this behavior is happening, tips on how to avoid this behavior, where to find API & other documentation on the older, deprecated JetPack work v1.0.1 library, or what I can do in Android Studio to better diagnose this issue, as attempts for debugging with what I know how to do have proven futile.

    Thank you very much for your time and help on this matter!

    Loss motivation and worrying myself for working as a senior android developer.

    Posted: 07 Nov 2020 07:25 AM PST

    Yesterday I took an interview at local top company as a senior android developer and I am worry myself as I have not enough knowledge to work with great people.

    And besides, I think I am not even a senior developer with 2 years of experience.

    So,I have no idea what to do if they offer me. I got imposter syndrome all these days and I am afraid to take challenges.

    Have you guys ever felt like that?

    Is it possible to change password after encrypting database content with Password-Based encryption??

    Posted: 07 Nov 2020 12:22 AM PST

    I am creating an android app where the app would encrypt some user data with AES Password based encryption. The password would be the password which the user used to create an account in the app. I am using Password based encryption because I think it is more secure than storing the Encryption keys somewhere inside the application.

    The problem is that user won't be able to decrypt the data if he changes the password.

    So is there any way to solve this problem??

    Or do I have to use other kind of encryption?

    Feedback for UI/UX & ASO

    Posted: 07 Nov 2020 03:54 AM PST

    Hi guys,

    My app recently has started get organic downloads - 400/500 a day!

    However my conversion rate is low, around 30%.

    How can that be improved?

    Also can you guys give me some feedback about the UI/UX? Is my app easy to understand? :)

    Right now I am fixing the core of the app, to allow users to type in any sentence rather than pre-selected sentences!

    Screenshot generator for Wear application

    Posted: 06 Nov 2020 08:12 PM PST

    I've developed some apps that work along with the Wear application. I've gotten away with not including the smartwatch screenshots. But I'd like for new users to see the Wear app in the Play Store and want to create screenshots for a picture that includes both the phone and the smartwatch in one picture or separate, if possible. There's plenty of sites that are free but are limited when it comes to smartwatch screenshots. Any recommendations are greatly appreciated!

    Android app project( desperately need help)

    Posted: 06 Nov 2020 04:37 PM PST

    Hello everyone,

    I'm really beginner at this Android development and I'm having a graduate thesis on it.

    The project is about sending measured data from arduino to Android app via bluetooth then appyling FFT on that measured data.

    My part is to get measured data from arduino ( probably data will be text file 1024x1) and make data ready for FFT

    We agreed to write everything in Java, but not sure where I should start.

    Your help and advices are more than welcome. Thanks

    Looking for creative ways to organize/store test devices

    Posted: 06 Nov 2020 08:08 PM PST

    Hey guys, new to posting here, not new to Android. I have a bunch of test devices (comes with the territory of supporting a million devices as we all know) and I was wondering if my fellow devs had any advice on how they keep their stuff nicely organized. What storage containers, chests, etc do you use?

    License testers VS LicenseD testers VS Public license VS Custom Android Studio license

    Posted: 06 Nov 2020 11:29 AM PST

    I would like to do Internal test of InApp purchases.

    What I did until now:

    -I have created developer account and merchant account.

    -I have compiled the code by using "Generate Signed Bundle/Apk" where I created the new Key

    -I have created the new listing for a test app in Internal test, uploaded file, and status is:

    "Available to internal testers "

    -I have added my test email in list with testers

    -I have added my email in the list with License testers and set option "Licensed"

    ​

    -I got url for downloading test app... which at the moment shows

    " We're sorry, the requested URL was not found on this server. "

    but ok, i guess that it is as stated... that it can take up to 48h for first time published app to become available to testers...

    ​

    What I dont understand now is this:

    ​

    I am reading google docs, and on this link:

    https://developer.android.com/google/play/billing/test

    ​

    " Ordinarily, the Google Play Billing Library is blocked for apps that aren't signed and uploaded to Google Play. License testers can bypass this check, meaning you can sideload apps for testing, even for apps using debug builds with debug signatures without the need to upload to the new version of your app. Note that the package name must match that of the app that is configured for Google Play, and the Google account must be a license tester for the Google Play Console account. "

    ----------------

    License testers can bypass this check, meaning you can sideload apps for testing, even for apps using debug builds with debug signatures without the need to upload to the new version of your app.

    This means that, for the purpose of internal test, I can just compile the code with my custom key and upload to google play?

    ​

    Ordinarily, the Google Play Billing Library is blocked for apps that aren't signed and uploaded to Google Play.

    If i compile my final app with my custom key and i upload to Google play as a final product then it satisfies this criteria that "it must be signed and uploaded to google play" ...or not?

    ​

    Or I have to use some public key as described here:

    https://developer.android.com/google/play/licensing/setting-up?fbclid=IwAR1o3EqaNO2RKOhtTEtjEFe3AW8NmBRxQ6VtZHHJXBr6ZRfx89pk7LnqnTI#runtime-setup

    ​

    TL:DR

    My app has in app purchases

    Can I use my custom key when compile app for purpose of internal test? Or I have to use public key?

    Can I use my custom key when compile final app for purpose of publishing in production? Or I have to use public key?

    Can I get some advice on moving forward with an app idea?

    Posted: 06 Nov 2020 10:14 AM PST

    The app's main function is to allow doctors and staff be able to quickly find contact information (phone, fax, email) for other doctors of the same specialty in our state. I will add a search function for the names and other doctors close to the user's location. There is a public excel spreadsheet on the website of the Board of Examiners with all this public information. My main questions are:

    1. Is it legal to have the doctors' contact information in my app without their consent given it is public information on a .gov site?
    2. What is the best option for creating the database? I have an excel spreadsheet with about 800 names and contact information. I've worked with SQLite, Room and Firebase in the past on small projects, but I want to use the best approach.
    3. If you were building this app as a solo dev, what approach would you take (tech wise)?

    A question about developing recommender sysems

    Posted: 06 Nov 2020 03:24 PM PST

    I have an android app with Rest java spring boot server, a virtual machine for server with 2 GB ram, which collects some user data and stores it in the database. I need to build a recommender system that uses those data to personalize a set of recommendations. I am new to backend development.

    ​

    I figured that I probably need to build a recommendation engine. I prototype with python locally and for example, I know I will implement bandit-based, content-based, and hybrid recommendation algorithms for three different use-cases. I mostly have prototyped with python.

    ​

    1. Which platforms or technology should I use for having the algorithms work online? since there are similarity matrix calculations etc.

    ​

    1. Can I use somehow python that accesses the same database and after calculating user-profiles update top-n for each user? or will it crash with java app accessing the same db?

    2. Or can I just do everything in my server java spring boot app, if so how? wouldn't it be too heavy since the server at the same time collects lots of user data, manual and sensor?

    3. Perhaps I should build a separate recommender engine. That way I would need an adapter for my java server app. How these could work together? What should I use?
