| How long did it take for your first app/game to be downloaded by random people on Google Play? Posted: 06 Apr 2020 03:15 AM PDT My first app, a chess game, has been published two days ago, and it has zero downloads by random people. I know that Google doesn't always recommend apps at the beggining, but I'm just wondering about your experience. How long did it take for your games/apps to be downloaded by random people? Edit: the link to my game is https://play.google.com/store/apps/details?id=com.LMProgramming.Chessbutmess , if you wan't to check it out. [link] [comments] | ||

| How is corona impacting your apps and business? Posted: 06 Apr 2020 12:18 AM PDT Is there a drop in revenue? How are you and your company working? Is your productivity and long term goals somehow affected? On my side, despite increase of installs revenue is dropping due to decreasing fill rates, productivity is gone because of uncertainty of what will happen with economy and ads. [link] [comments] | ||
| What's my best choice for background jobs that occur every 2 minutes regardless of the app's state? Posted: 06 Apr 2020 07:24 AM PDT I tried using WorkManage (JobScheduler) but they only work for > 15 min periods. I also tried using a regular Service with a Timer & TimerTask but i feel like that's not a good idea and my service always gets killed. I need a way to periodically send a POST request (I use OkHttp) every two minutes regardless if the app isn't in foreground - and i would like to start the period on boot. [link] [comments] | ||
| Play Store Appeals are ridiculous Posted: 05 Apr 2020 11:50 PM PDT I recently had an app removed for "impersonation" so I wanted to change the title as well as the description to make it clear that I was not affiliated with the entity. I went to the store listing tab to find it empty, as well as all other tabs; I could not make any changes. I made an appeal saying I agree with their decision and I would like to fix it but I can't. After a week of review I get an email back explaining what impersonation is and telling me to fix it. I can't take the Google team seriously anymore [link] [comments] | ||
| Posted: 06 Apr 2020 07:10 AM PDT So I'm new to Android Development, and trying to get Android Studio (3.6.2) setup on my MacBook Pro running MacOS 10.15.4 (Catalina). Every time I try to set up a device in AVD Manager it crashes. Here is a portion of the report:
I'm looking for any ideas, I tried several options that I've found via Google, but none of them have been the magic I'm after. TIA [link] [comments] | ||
| Posted: 06 Apr 2020 07:02 AM PDT Hi I'm currently testing to see if I can learn best with online courses, tutorials or books. Right now I've got this eBook and everything is going great, that is until he started to use sprites. First a grassy tile and then "Squarey". Nowhere does the author mention where to get these sprites from or how to create them...am I going mad or did I miss something? [link] [comments] | ||

| adding a sliding overlay panel in SupportMapFragment Posted: 06 Apr 2020 02:37 AM PDT I'm interested in learning how to implementing an activity UI somewhat similar to this one found in the Uber Driver app. particularly how would you add a panel that slides up and down (not sure of the proper name) over a Google Map? Any codes examples would be helpful. [link] [comments] | ||
| Posted: 06 Apr 2020 05:39 AM PDT Hi All Newbie here. In college I previously used unity to create a side scroller game and found unity great to use. I am now looking to develop an android game. More specifically a 2D multiplayer card game based off of a popular card game here in my country. Is unity the platform to use here or does anyone have any other suggestions? Thanks for your help in advance. [link] [comments] | ||
| I'm making an android app for a client and I don't know how to deal with the pricing Posted: 05 Apr 2020 06:11 PM PDT I just graduated last year October and was hired as an Android Developer on the same year November. I don't have much experience but I am willing to learn on new things. In my current work, there is no android app project yet so they allowed me to help with other teams working on a website. So I don't really count it as an experience. I'm currently working from home due to coronavirus. And I received a project from a restaurant (not client project from my company). This is my first time working on an actual project. I've made projects before but for thesis. Can you help me out? I'm really new to this. Here are my questions: How much should I ask for the price? Thank you so much for your reply. [link] [comments] | ||
| Can you explain me singleTask launch mode in Android? Posted: 06 Apr 2020 04:55 AM PDT Hello, everyone! I've been trying to understand launch modes in Android. I can't understand much singleTask. Can you help me?
I found plenty of articles with such kind of interpretation. Okay, now I have the second question about how to implement this thing (mb, it will depend on the first question). Let's imagine that I have activity A and activity B. In addition to that I have a foreground notification. I want to realize the next thing: when a user clicks the notification it will send the user to Activity A, no matter if activity B was on the focus. I want to destroy automatically activity B, if it needed, and go to activity A with the same state. How to implement this feature? [link] [comments] | ||
| api 29 emulator v30.0 + broken on MacOS? Posted: 06 Apr 2020 04:27 AM PDT Hi all, We run automated tests on the android emulator and recently found that our api 29 builds have started failing. It seems some I think this may have started with version 30.0.5 of the emulator. I tried upgrading to 30.0.6 and now 30..0.7, without any luck. repro: ``` create avdavdmanager create avd -n api-29-bug-emulator-30.0.7 -k "system-images;android-29;google_apis;x86_64" -d pixel run emulatoremulator -verbose -avd api-29-bug-emulator-30.0.7 wait for boot, then in another terminaladb root ``` will hang, or timeout. the logs show the following: ``` emulator: OpenGL Version=[OpenGL ES 3.0 (4.1 ATI-3.5.5)] emulator: VERBOSE: AdbInterface.cpp:385: Found: 3 adb executables emulator: VERBOSE: AdbInterface.cpp:387: Adb: /Users/clem/Library/Android/sdk/platform-tools/adb emulator: VERBOSE: AdbInterface.cpp:387: Adb: /Users/clem/Library/Android/sdk/platform-tools/adb emulator: VERBOSE: AdbInterface.cpp:387: Adb: /Users/clem/Library/Android/sdk/platform-tools/adb emulator: No acpi ini file provided, using default emulator: VERBOSE: AdbInterface.cpp:408: Path:/Users/clem/Library/Android/sdk/platform-tools/adb protocol version: 41 emulator: VERBOSE: AdbInterface.cpp:408: Path:/Users/clem/Library/Android/sdk/platform-tools/adb protocol version: 41 emulator: VERBOSE: AdbInterface.cpp:408: Path:/Users/clem/Library/Android/sdk/platform-tools/adb protocol version: 41 emulator: VERBOSE: winsys-qt.cpp:919: config multidisplay with config.ini 0x0 0x0 0x0 emulator: _hwFingerprint_connect: connect finger print listen is called emulator: got message from guest system fingerprint HAL emulator: onGuestSendCommand: [0x7fd1a7b39c80] Adb connected, start proxing data emulator: INFO: boot completed emulator: INFO: boot time 29931 ms emulator: Increasing screen off timeout, logcat buffer size to 2M. emulator: Revoking microphone permissions for Google App. emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | emulator: VERBOSE: System.cpp:1486: Timed out with running command |/Users/clem/Library/Android/sdk/platform-tools/adb -s emulator-5554 shell settings put system screen_off_timeout 2147483647 | ``` So clearly something is going on with adb... I tried reporting this to google but the Can anyone confirm / deny this? maybe an emulator dev will see this? It affects several employees from my company. Happy to provide more logs if needed of course. [link] [comments] | ||
| Loading animation (custom inderminiate progress bar/custom animation) Posted: 06 Apr 2020 04:20 AM PDT Hello, I just wanna ask, what is the best practice to do this animation (just the animation) for progress in Android (Java). Just like it can be seen here ... I want to do it with my custom image. I am asking because I am not so experienced with animation building and i wanna do it in the best way it is possible. One way would be like that here ... but i think that there could be better way to do that for styling the progress bar. I have done some more research and I did not see anything like that. Eg here (i use preferably Java) Any help would be appreciated. [link] [comments] | ||

| What is Kotlin feature you use in Android that is hard to implement in Java? Posted: 06 Apr 2020 02:59 AM PDT I know one is Data Class, but what else do you think is hard to do in Java? [link] [comments] | ||
| Map<String, List<Item>> inside recyclerView Posted: 06 Apr 2020 02:45 AM PDT Hello. From someone who came from cross-platform development, I have hard time to understand recyclerView in android. I can populate a simple list using recyclerView with no problem now, but i've problem with more complex list. As described in the title, i've Map<String,List<Item>> and want to display it in a recyclerView. the header will be the Key, and underneath that List of all the values of a given key. How can I implement this using kotlin? Of course i'm open to 3rd libaries Thank you for your answer in advance [link] [comments] | ||
| Is it possible to use WorkManager to launch an App? Posted: 06 Apr 2020 02:00 AM PDT I've been struggling with this for days, and I can't find an answer or example of this online. Have you ever tried it? This is how I'm scheduling the Work from MainActivity: This is my AppLauncherWorker class: My understanding from the documentation is that a Work starts a process, does something, and when it's done, the OS kills that process. But if I launch an activity, that should start a new process, right? And when the OS kills the Work process, the activity shouldn't be killed with it... In my tests, it never enters MainActivity's onStart() method. Is it even possible to launch an activity from a Work? Is it possible to launch a Foreground Service from a Work? What am I missing?

| Posted: 06 Apr 2020 01:49 AM PDT I've always been a big advocate of native apps. Proper integration with the platform etc. However the cost of developing two apps (frontends) is more than some clients can afford. What are your experiences with multi platform app development? I don't like the idea of using something like Xamarin. But I could be open to the idea of having a responsive web page which could be packaged in an apk and... Whatever iOS uses.

| Posted: 06 Apr 2020 01:06 AM PDT Hey, there.. I am currently in the process of developing an application and in the contact section, I want to include a email section where people can reach out to me via email. I want to include a from, subject and body section. The recipient portion would be fixed. It would contain my email id. How can I achieve this ? I am very new to android development and any help would be appreciated. [link] [comments] | ||
| Posted: 06 Apr 2020 12:23 AM PDT Hi all, my app is live on Play Store and recently changed the screenshots in Play Store listing, but when I see app details on Mi app market - GetApps , I see old screenshots and old app version. I have never uploaded app on Mi app market and have no idea how apps appear there(need to know that as well). How do i update my app there with new screenshots or does it even make sense to do that!!
