    Need help switching to kotlin and also on how to learn unit testing in android.

    Posted: 14 Feb 2021 04:10 AM PST

    Hi guys,do you know any good courses for an android developer who's worked in java his whole career to learn kotlin from? Also any good material on unit testing and stuff would be great too. Thanks in advance.

    Do you trust your CI/CD provider with your app key, user and password?

    Posted: 14 Feb 2021 02:42 AM PST

    I am playing with Codemagic in order to automate the process of deployment of my apps, but I have some concerns regarding the delivery of my app keystore, its username and passwords.

    They definitively need this information to sign the final apk, but they could potentially create new releases with a valid sign at any time.

    In a case of a security breach, this very sensitive information could be used to create trusted versions of the apps.

    So my question is: for any of you that have a CI/CD tool set for deployments, do you trust them and provide the key and access to create signed APKs? Is there any way to provide some kind of 'temporal' access or something that can be made in order to revoke access at any time?

    Is the "Android Basics" course provided by Udacity still relevant?

    Posted: 14 Feb 2021 03:31 AM PST

    Considering the fact that it was made in 2016. Is it still worth taking for a guy who wants to become an android developer.

    Real-time data API calls

    Posted: 14 Feb 2021 02:11 AM PST

    Currently working on NBA live score app and am wondering if making api calls on Android means each device with the app would be making the call, and if so, would this have any effects on using the api such as rate limiting.

    If not, is it good practice to make the api calls from android or from a central server and then send the data to the app?

    Can't find the answer to this on the internet.

    Thank you!

    How do I deal with user problems like this?

    Posted: 13 Feb 2021 01:14 PM PST

    I've just released a new version of my app to the Play Store, later I receive an email from a user saying this:

    Dear sir/madam,

    Digital TV Antennas App updated today, yesterday I used the app and all was correct and normal. Today following the latest update your app doesn't work. At the start when the display appears it is greyed out (screen shot attached) and any attempt to access setup or anything else just closes the app. Please can you look into this issue and resolve the problem I currently have.

    My app does not "gray" the screen, he says the app crashes, yet I haven't seen any crash on Crashlytics or Play Store Console. I don't think I can get the user to install adb and send me a logcat. I hate it, but I can only reply: "I'm sorry, I can't figure out a way of helping you or debug this". Are there better options?

    What would be the *simplest* solution to find a string of text on screen in a running android app ?

    Posted: 14 Feb 2021 04:34 AM PST

    Yes, selenium, yes, openvino... or openCV... i get it.

    But for the problem I have, it's like smashing a nut with the most modern tank in history. All i need to do:

    a) an android app runs

    b) the screen displays words, amongst other things, like images, and drawings

    c) i need a program that isolate the words , and if it match a list of potential words, warn me of the timestamp it was shown at

    You're going to say "why the timestamp" - it's because I'm SO lazy i am just going to record my screen so i don't even have to infer anything else about the meta-data of the app at any given time.

    In other words, I want the tinder swap machine of computer vision/ocr: the dumbest possible implementation, even if it involves pointing another phone at a running app on an emulator. Literally anything, i just need to get it done before the end of the week.

    Thank you!

    Want to hear some opinion and thought about personal and business google account.

    Posted: 14 Feb 2021 07:39 AM PST

    I just getting into registering for the google play console to release my own app but for some reason, I am not sure which one should I use to register either personal or business. I have one google account for personal and one for business but right now. I just want to register under my personal account.

    but I'm not sure if it is good or bad to register it under a personal account because I'm planning to combine it into my business account.

    Can I register it under the personal account and later on if everything works well can I register a business account at the google play console and add on my personal app projects that were launch. Not sure but is it possible or not possible? Sorry guys but I don't know whether this is a dumb question.

    But much appreciate it if you could give me some opinion and thought on this.

    How does the "auxiliary cameras" feature work on Gcam ports?

    Posted: 13 Feb 2021 11:03 PM PST

    There are many Gcam ports that have an "auxiliary cameras" feature that, when enabled, usually allow Gcam to access all available cameras on the device, even ones not listed when you run a Camera2API report on the same device.

    OpenCamera, for example, seems to rely almost entirely on Camera2API - if a certain camera isn't shown in Camera2API, it also won't show up in OpenCamera, but Gcam somehow bypass this entirely with "auxiliary cameras." The mcpro24fps video recording app is another app that supports far more cameras on a device than Camera2API indicates is available.

    How does this work? I can't seem to find documentation on this workaround.

    Clarification on AndroidX Nav component

    Posted: 14 Feb 2021 03:29 AM PST

    So I was reading the android devs guide on the Nav component and noticed that 2 of the 3 "key parts" are greyed out. This means that the classes are deprecated right? I should only use NavHostFragment and Navigation graph?

    Ad mediation networks - enhance.co and appodeal

    Posted: 13 Feb 2021 06:26 PM PST

    Thank you for helping me with the last post. I recently discovered ad mediation networks and felt it was a better model and I also note that even admob has their own too.

    Just wondering what people think about enhance.co specifically? I feel like their web tools sounds awesome and simplifies adoption and maintenance vs other systems because they integrate SDKs into their platform so you need to know little coding. and I can see their tutorials on YouTube.

    They do not charge any fees/commission and make their money elsewhere so there is no reason for them to be shady. Your feedback would be appreciated!

    Appodeal is also another model I really admire with their business model and the option to get immediate payout of you want. Plenty of review so not too concerns and this is available on the enhance.co platform too.

    TIA!

    What order do you guys release your apps?

    Posted: 13 Feb 2021 10:49 AM PST

    Hey all!

    I'm working on releasing my first app to the playstore and was hoping for some clarity on different tracks.

    My current understanding of the playstore stores are,

    • internal : I have to manually add people's emails to a list, and from there they can see it on the playstore.
    • alpha : Unclear
    • beta: Unclear
    • release: Free game for everyone to download

    I have 4 branches for my code base master -> alpha -> beta -> release

    Currently, whenever I merge code into alpha, it auto builds the app and I upload it to my personal server, I then send the link to the two people that are helping me test my app.

    Once the app is completely finished and I'm ready to release into production, my ideal scenario would be...

    When I merge into alpha, the people I added to a specific email list will get a notification on their playstore that there is an update for my app. No one else can download this app from the playstore.

    Once the internal people test my app and all goes well, I merge into beta, I would like these to be people anybody that has a link to my app as well as people who are beta users of the playstore. I would like only beta users to be able to search for my app on the playstore and download it.

    When I see everything is good, I then merge into release with a 10% roll out. This is anybody who has access to the playstore. After a week or so, I then set it to 50%, and then 100%.

    Does this sound like it makes sense?

    Is this possible with these current tracks?

    I guess I just want clarification that what I'm saying is correct/possible?

    I especially want to make sure that for builds that go into my alpha branch, it really is as easy as just adding someone's email to a list and if I send them the play store link, they can download it and then they'll get notifications about there being updates within 10ish minutes.

    Thank you all so much!

    Is 128GB RAM an overkill for Android dev?

    Posted: 13 Feb 2021 01:58 PM PST

    I currently have 8GB RAM, 250 GB storage i5 CPU. Build time is pretty slow with big projects and even slower when using emulator. (Windows)

    I found a laptop for 128GB RAM, 2 TB storage, and i7 CPU. Is this an overkill? What specs should I go for, and should I try Linux instead?

    Do you interested in learning web development as a mobile developer?

    Posted: 13 Feb 2021 12:02 PM PST

    Do you interested in/want to learn web development?

    As an iOS and Android developer for a long time, I have learned Next.js, Vue.js etc and it has similar patterns with mobile development. Also somehow you have to do it even if it is for marketing purposes. (This is why I have started learning it). I am considering making a course with this context. Do you want to learn web development by the eyes of a mobile developer?
