    Here's your chance to talk about whatever!

    Although if you're thinking about getting feedback on an app, you should wait until tomorrow's App Feedback thread.

    Remember that while you can talk about any topic, being a jerk is still not allowed.

    PSA: Google survey about Scoped Storage for Android 11

    Posted: 06 Mar 2020 02:47 AM PST

    Aspiring Android developer discouraged from reading about bans - would you still choose Android as a career if you did it over?

    Posted: 05 Mar 2020 10:41 PM PST

    TL;DR at the bottom.

    A bit of background about me: I'm 27 and finishing up a degree in Computer Science. Lately I've been interested in Android development and working through their official code labs and concept chapters. I love Android Studio and enjoy the Android platform with its fun phone sensors and other features to work with. I've been planning on focusing on this and pursuing a career in it.

    However, I'm discouraged after reading about Google's treatment of developers (for example, removing apps without clear instructions and support about policy violations, or even worse, an outright developer ban).

    My biggest fear is if I somehow got permanently banned from the Playstore, that would severely limit my employability as an Android developer - especially as a new one. I'm not planning on making spammy apps, but from what I've read it seems that Google can sometimes be vague and capricious in removing apps and banning developers.

    How likely is a permanent ban if you try to follow their policies? And if worst case scenario you do get banned, would that actually affect your employability as an Android developer? Or am I worrying about this too much?

    I actually have a course at school for Android and need what I've studied so far to pass it, so even if I don't pursue Android development professionally, my studying hasn't been for nought. And I've got front end experience as well as Java, so I may go one of those routes instead. Or possibly learn React Native and try to find a job doing that.

    Am I overthinking this? Would you, a professional Android developer, still choose this as a career if you were in my shoes?

    TL;DR Considering a career in Android development, but worried about being banned from the Playstore even if I try to follow policy. Biggest worry is a ban affecting my employability. Is that a legit worry?

    How do reach out to someone at Google Play? I tried updating the logo for the application I am developing, got rejected saying we are impersonating a brand. I didn't know there was chat support in Google Play, I tried last night and this morning and I see this. What is 12am - 12am (GMT)?

    Facebook punishes my Android game: Your app cannot be installed by new users. ��

    Posted: 06 Mar 2020 01:58 AM PST

    Hello,

    since over 2 years I run a small (150 mobile users, a bit more on desktops) word game, without any IAP or ads (I don't like ads and I haven't implemented IAP yet).

    The mobile version is published at Google Play, Huawei App Gallery, Amazon.

    Users can login through Google, HMS, Amazon Login and - Facebook login.

    Yesterday I have gotten the warning mail by Facebook: "Your app is in violation of our Platform Policies"

    Being an indy dev I live in constant Angst and thus I have immediately updated my app at Google Play (changed the Facebook icon from greyscale to blue-white) and re-entered the base64 hashes in Facebook settings. I haven't fixed anything more because actually the Facebook Login just works in my little app.

    And of course this didn't help and now my app is:

    Your app XXXXX XXXXXX has been restricted for creating a negative user experience in violation of our Platform Policies. Your app XXXXX XXXXXX has been restricted for creating a negative user experience that is in violation of our Platform Policies.

    • Your app cannot be installed by new users.

    I understand many things, been watching devs in this Reddit being banned last year by Google robots, understand that Facebook uses similar robot scripts...

    But how on Earth does Facebook want to forbid new users to install my Android app? What do they mean by the above restriction (and yes the Facebook login still works in my game).

    P.S. My game is super clean: no ads, no IAP, all-native Java, here few screenshots: https://imgur.com/a/2m2X3Pa

    Glide image library being reported as malware by AVG, Avast

    Posted: 05 Mar 2020 02:13 PM PST

    I spent 6 hours paring down this issue, removing one library at a time. Hopefully this information is useful for others who are hitting this issue.

    Starting today, AVG and Avast (they are the same reskinned app and have combined over hundreds of millions of downloads) started reporting my apps that use Glide (4.8.0 and 4.11.0) as malware. I reported it to AVG as a false positive already, but don't expect a quick fix from them.

    When I replaced Glide with Picasso, the apps are no longer marked as malware. I've already received about 10 bad reviews and dozens of e-mails about this issue and have not updated my app recently, which leads me to think they updated their algo very recently. I have tried disabling proguard but it makes no difference.

    Quick fix is to replace Glide with Picasso and the issue goes away. Replace:

    • Glide.with(context).load(uri).into(imageView)

    With:

    • Picasso.get().load(uri).into(imageView)

    In gradle, replace:

    • api "com.github.bumptech.glide:glide:4.8.0"

    With:

    • api 'com.squareup.picasso:picasso:2.71828'

    P.S. Since I linked this post from other places: If you're not familiar with Glide, it is a popular library/toolkit used by Android developers for showing images inside Android apps (such as images in news feeds). It does not have any tracking, malware, or advertising and the code is all open source: https://github.com/bumptech/glide

    Hey guys, I'm trying to install the latest version of the android studio commandline tools on my Ubuntu environment.

    The problem is with the directory structure needed for the installation (from what I, it's different in the latest version from the older ones).

    I always receive a warning that it wasn't able to create settings when I try to use the sdkmanager.

    Any help is appreciated!

    How do I use Authenticator with Coroutines?

    Posted: 06 Mar 2020 06:56 AM PST

    I am using the interceptor class to retrieve a new access token, but I think the problem that occurs is that I am using a coroutine to retrieve it and return it and it returns an empty string.

    Developing your own in-app update system. Best way to avoid random app/account ban?

    Posted: 05 Mar 2020 11:20 PM PST

    I am seeing a lot of horrifying stories of developers whose apps are getting banned for frivolous reasons. An account ban automatically tarnishes your image as an android developer, and people may no longer be ready to work with you. All because you did a silly mistake or there was no mistake at all and Google bots just nuked your account due to false alarm.

    I was thinking this. Once your app does get published on Google Play, you are pretty much safe till you try to upload a next update. At that point of time, your app is scanned again, and you keep your fingers crossed that it won't be rejected/lead to a ban.

    So why not add an in-app updater? It's pretty easy actually. You put a file on GitHub/Gitlab with update definition (current version of the app and url for direct download of the update apk) compare the current version of the app with the update definition and if your current version is outdated, download the new update apk and prompt the user to install it.

    Atleast once your app gets published for the first time, you won't have to deal with unnecessary fears of getting banned in a future update. (Unless Google re-scans the app and finds it violating policies or anything similar)

    How can I count how many times the device was shaken in a given time?

    Posted: 06 Mar 2020 01:23 AM PST

    Hi everyone !

    I'm a real beginner and I need a part of my app to count how many times the user has shaken the device before the end of a given time.

    I've found multiple tutorials explaining how to count the number of time a device was shaken, so I'm currently able to display the number of time the device was shaken, via the code bellow, but I can't stop the count at one count...

    (sorry, I don't know how to display code properly)

    public void onPlayer1BtnClicked(View currentView){ shakeDetector.setOnShakeListener(new OnShakeListener() { @Override public void onShake(int count) { Toast.makeText(getApplicationContext(), "Shaken : " + shakeDetector.getNbShake(), Toast.LENGTH_SHORT).show(); shakeDetector.setNbShakes(count); } }); Toast.makeText(getApplicationContext(), "Times up : " + shakeDetector.getNbShake(), Toast.LENGTH_SHORT).show();}

    ​

    If you can help, thank you very much :)

    So I want to know how to make reddit like effect in Android when we click a image of some post. So image gets open and we are able to zoom it and swipe up and down to dismiss it. Also I like the gradual change of opacity when swiping up amd down. Is there any library or tutorial for doing the same?

    Installing multiple app flavours simultaneously on a device

    Posted: 05 Mar 2020 05:28 PM PST

    I've got an app with multiple app flavours with unique package IDs (different suffix added depending on the flavour).

    ​

    Let's say that's flavours A, B, C, D, E.

    ​

    I'd like to install all five of those flavours to an Android device simultaneously so I can give it to the "Client Relationship Manager" dude in my company who can test the apps before client meetings.

    ​

    I'd like to automate this because I have to reinstall all the flavours for every change in the codebase... How do I go about this? Android Studio can only let me install one flavour's debug version at a time.
