    Google human support where is it now?

    Posted: 21 Feb 2021 01:25 AM PST

    how do you contact google support on Chat??? i can't talk to them since they moved to the new Play Console platform! why they are hidding behind support questions, they removed one of our Apps for a very old version on closed track, couldn't remove that version what was easy to do on the classic Console.

    Is animation smooth on Android 11 AVD on your computer?

    Posted: 20 Feb 2021 05:50 PM PST

    I had installed Android 11 AVD when it had just come out. I noticed stuttering/flickering animations, which did not happen in previous versions of AVD (10, 9, 8...). I thought it was an early issue and would be fixed soon. Unfortunately, to this date when Android 12 Beta AVD has been released, it is the same.

    Here are the screen recordings of Android 11 and 10 AVD's: https://filebin.net/7pj5klu15xalpvj8 These two AVD's are just created and I have not changed any settings. Both are x86 (64-bit) Google Play.

    What has changed in Android 11 to make this difference? And why it has not been fixed? Most people don't have this issue, and am I one of the minorities who are experiencing this? For what it's worth, the graphics card is RTX 2060, and I am using the latest Studio driver (which is supposed to have passed more rigorous tests and thus stabler...).

    How do you come up with ideas?

    Posted: 21 Feb 2021 07:29 AM PST

    I am looking to start a project and go full time into it but I just can't find any ideas for apps how do you come app with your next project? Maybe silly question but I burned my self from continues session on python (currently learning) and I really want to upload an android app sometime in the near future but I don't want to be something stupid.

    Current state of the art for polling in the background?

    Posted: 21 Feb 2021 06:23 AM PST

    In my current personal project, I want the App to poll a REST service roughly twice a day and send out notifications depending on if there is new content available. The timing does not have to be exact and can really heavily vary.

    Some years ago I used the AlarmManager + a BroadcastReceiver for notifications which have to be exactly on time. With all the background task restrictions in the last three years I really lost track of the current state of the art and now searched through the documentation and am still left with uncertainty.

    I only need someone to point my in the right direction here. Is it the JobIntentService or is the AlarmManager + BroadcastReceiver still the way to go?

    Room Database in IntelliJ IDEA Apple Silicon

    Posted: 21 Feb 2021 01:22 AM PST

    First time I will post a bug around here. I have been implementing Room Database in a project and I got this error:

    Caused by: java.lang.Exception: No native library is found for os.name=Mac and os.arch=aarch64. path=/org/sqlite/native/Mac/aarch64

    I will report it on YouTrack but I wanted to know if someone else has happened to him and how they have solved it. Yes I have replaced the JDBC in Contents/lib to version 3.34.0 but the error is recurring.

    I used IntelliJ IDEA 2021 EAP 3 and 2020.3.2. Both with the same problem.

    AOSP Flame Kernel Compiled Sucessfully, but it "failed to find device default fstab"

    Posted: 21 Feb 2021 04:33 AM PST

    I tried looking for a solution a lot, but all I managed to get are threads that do relate to development boards: https://community.nxp.com/t5/i-MX-Processors/Android-9-Filesystem-not-Mounted-on-imx6q/m-p/1034102

    Or threads that I don't understand: https://github.com/danielfullmer/robotnix/issues/4 ¯\_(ツ)_/¯

    Ok, so I did the following to to build the AOSP Flame kernel:

    mkdir AOSP cd AOSP repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r41 repo sync -j`nproc` source ./build/envsetup.sh lunch aosp_flame-userdebug m #### build completed successfully (09:45 (mm:ss)) #### 

    And... All of that worked like a charm. However, when I type emulator, I get a black screen on the emulator window:

    The emulator window showing black screen

    So, I tried emulator -show-kernel -wipe-data -no-snapshot, which gave me more info in regards to why this isn't working:

    Posted: 21 Feb 2021 05:34 AM PST

    Whenever I think about my app UI (layout) I found it worse but when I actually look at it it's only bad (better than worse) ........ and this thing keep happening in loop so how can I truly self-review my app UI ?

    Are the in-app purchases in my app working?

    Posted: 21 Feb 2021 04:52 AM PST

    Hi ever since the last update to my app I've been getting zero in-app purchases which has gotten me worried.

    Can I get some help? Just open the app and tell me if the pizza icon (which when pressed should show the option to buy premium) is working. Thanks 👍

    RecyclerView: Show "Favourite" items on top

    Posted: 20 Feb 2021 03:45 PM PST

    I am loading some texts from XML file to recyclerView. Each of recyclerview item will have favourites button.

    Firstly, I was planning to store selected item index (on favourites click) in a List, store it in preferences/db, and then on next init move favourites indexes on top of list. But the problem is, if I move the item in recyclerView to top, new indexes of items wont match Texts in XML file (if you know what i mean).

    So I need any other options for saving favourites texts. I could just save list of string and then compare each of them, but I think this is not the most efficient way, heh

    Android 11, is it possible to install apps outside data folders/vmos

    Posted: 20 Feb 2021 12:36 PM PST

    Android 11 or one UI3 are making virtual root functions impossible. All i can figure is that its detecting the app-within-the-app trying to access the apps system files. So is there a way to install an apk into a folder that isn't "protected"

    If all you had was an unrooted Android 11, what tools would you need to work on your apps?

    Posted: 20 Feb 2021 12:51 PM PST

    Android 11 has made virtual machine root useless. Apps think they have superuser privilege but can't access anything.
