    Android Dev - What to use for specific app

    What to use for specific app

    Posted:

    So i have been coding for about 3 years now, not on a professional level, but in school and privately. In my last year of school you have to code an mobile or a web application together with a company. So far i couldn't find the right answer for my specific app.

    Last year in summer i started to work on this app in my free time, which is for my dads company. I used firebase and android studio. It took me a good while to get started and code an app, which uploads and downloads data to firebase realtime database. Along the way i started to think about, if that database and the environment is the best thing to go for and optimal for the future. So i am asking, what language (and environment) and database is the best for up and downloading data in realtime, creating a web application to also download the data onto the pc with an interface and also designing the UI for mobile to look modern. (It's not a must, but if the database also works with IOS devices its good for future development). Thanks to all the answers and help!

    Love these rich documentation pop-ups in Xcode. Does anyone know a comparable plugin or something in Android Studio?

    Ready to publish my first ad-supported App - do have to worry about the GDPR?

    Posted:

    As the Title says I am currently in the processes of finishing my first Android App which started to develop few months ago as a hobby. The App entirely written in Kotlin to get to know the language better by developing a real project.

    Obviously I also want to publish the thing to the Playstore for others to enjoy it and in order to make at least a bit money back I added two banner ads with ad mob. I am by no means expecting to soon make thousands of € overnight, but some bucks to buy a cup of coffee every few days would be nice.

    The App by itself collect zero data on the user - in fact it doesn't it doesn't even require or ask for any networking or internet related permissions. Really all I do is initialize ad mob and then load two ads to display them.

    Now that I read more in the subject I started to worry about the GDPR. Since I myself life in Europe and the App is likely to be used by at least some Europeans - can I as an individual be sued for not asking for consent or providing legal stuff when publishing my App on the Playstore even if I collect zero data and I am not a corporation and just a single dude who developed an App?

    Help with .keystore file

    Posted:

    This is the first time i've had to request a replacement keystore from google to upload a new version of my app. I made the .jks file and the .pem file, they emailed me back saying everything is good now, but wait 48 hours. I thought (because im a noob to this) that they would email me a .keystore file or upload it to my account, but i have not received one. Maybe i messed up somewhere, but i still have the .jks file and the .pem file, is there additional step that needs to be done in order to create a keystore? I am getting very confused with the google searches i have been looking through, i end up just creating more .jks files.

    Any help with this would be great.

    NetworkBoundResource approach

    Posted:

    Hello.

    I've found this recommended LiveData type from Google and seems a great way when working with single calls from an API. But was wondering how could it be implemented in case of a list of objects instead. Which could be updated or not independently.

    Let's say I have a fragment showing a LiveData<List<Object>>(). Each of these objects might be old enough, or not, to be updated once retrieved from Room. What I can't find how to implement in this case is the 

    protected abstract fun createCall(): Flow<ApiResponse<RequestType>>

    method. Since in my particular case, the API service only accepts single calls for each object.

    Could there be any workaround for such cases?

    Thanks.

    Should we let our mobile app talk directly with S3 storage like Digital Ocean Space?

    Posted:

    Currently, we are using Google Drive, as cloud storage for our note taking app.

    However, Google Drive is not flexible enough to achieve what we want. We would like to offer alternative cloud storage to our users (Bigger storage, more bandwidth efficient, ...)

    We plan to purchase storage either from Amazon S3, or Digital Ocean Space which is S3 compatible.

    ​

    1. I was wondering, should we let our mobile app talk directly (Bucket creation, Batch files uploading, Batch file downloading, ...) to S3 storage service? But, if we want to do so, then we need to embed the API secret key into the mobile app. That doesn't sound like a good idea as far as security is concern.
    2. But, if we want to avoid so, we need to have a web app in between. Mobile app will first perform batch upload to the web app. The web app need to perform authentication (using Google login token), and have a cron job to again perform batch upload to S3 storage service. Having large batch files (We are talking about few GB) to first go to web app server, then only pass them to S3 storage also doesn't seem an efficient solution. As, then will consume a lot of our web app bandwidth quota, besides consuming the bandwidth quota of S3 storage service.

    I have wondering, does anyone here has experience in providing own built cloud storage for your mobile app? May I know how do you design the architecture for your mobile app + cloud storage service?

    Thanks.

    Using data from external website on your app

    Posted:

    I'm trying to make an app that'll show the daily and total coronavirus stats in my country . There's a national website for that with the necessary stats but I couldn't find a link to a dedicated API on their website. How can I take the stats from the website and display them in my app? Also I'm aware several similar apps already exist. I'm making this mainly for practice

    "You're just too junior." What am I supposed to do with this?

    Posted:

    I recently got a call back about a job and was told they were pursuing someone else because I was "just too junior". This job required only 1 year experience and, from what the requirements suggest, a basic understanding of API and Material Design.

    That's it.

    The bar was literally as low as it could be. I've published apps that use everything they were looking for. I'm not trying to say the job was in the bag or anything dumb like that, but what am I supposed to do when, despite evidence to the contrary, I come off as "too junior". There are more interviews coming up and I would love some insight and advice.

    Thanks.

    Is it worth buying downloads?

    Posted:

    Hi all,

    I just recently released a game and I'm trying different marketing/advertising options, mainly to gather real live experience what works best and also in the hope to increase some downloads. ;)

    One thing I came across several times now is to buy downloads. This is suggested mainly for two reasons: 1. The Google algorithm (is supposed to) push your app/game higher in ranks the newer it is and the more downloads it generates in a short time. 2. To increase the number of downloads shown in the Playstore because apparently an app with 10.000 downloads appears more worthy to install than one with 10 Downloads.

    Now I concluded that it makes sense somehow. I also figured that you have to pay attention to a few things:

    • the downloads must be real installs (no script downloads from a PC/Server)
    • it is better to have installs that last at least 3 days before it gets uninstalled again
    • installs should be geographically spread and not just come from one location
    • installs that come after a keyword search are the best

    Assuming all criteria is given, right now I think it isnt a bad idea to pay a little for such a service. However my hesitation lies in the "little".

    Considering/assuming that the top 100 games all have at least 100.000+ downloads will buying, lets say 500 Downloads a day for a week actually help to get to a valuable rank? Or would one have to throw thousands of Dollars into Downloads just to have a glance of glory? :D Or is it all just a scam?

    Anyone has some experience with that? Thank you!

    Best

    Images to use in my gamep

    Posted:

    Hi!

    I'm making a trivia game and it contains around 60 categories. I found all of the images on flaticons by freepik that I want to use in my game. The question is how should I attribute properly for those images on google play store description section. Also, is it risky to use free icons. Although they say on their website you can use them in commercial or personal projects if you attribute the author I'm still very cautious to use them because of google play policies.

    Should I use api or implemetation for my library dependency

    Posted:

    I understand the difference between api and implementation and how they should be used in which circumstances, however I'm struggling to decide which one I should use.

    I'm building a plugin that extends on BottomNavigationView from the material.io package. When use implementation it's not possible to do for example:

    findViewById<BottomNavigationCircles>(R.id.bottomNavigation)

    because the parent class cannot be found until the material dependency is added in the app itself.

    So which one is the better approach:

    1. Change the material dependency to api
    2. Tell users of the library to add the material dependency themselves.

    Alterative to Sceneform for AR? Sceneform Plugin refuses to stay installed.

    Posted:

    I've tried installing the Sceneform plugin for an AR app I'm building at least five times now, over more than one version number. I'll restart the IDE, go to the Plugins page, and it doesn't appear. I have to reinstall it every time and it never sticks.

    I'm aware it's moved to open source and its archived now, but I'm not sure how else to build apps using AR without it, considering all documentation points to Sceneform being the "best" option. Or, rather, how do I build AR apps without it?

    Paid/Fake Reviews

    Posted:

    Hi,

    I see that most apps have fake or paid reviews. Is it worth it? Does it rank your app higher? Are the downloads more important?
