    Android 11 scoped storage - MediaStore can create sub-directories, delete - but are rename-file/move-file instantaneous as before ?

    Posted: 26 Oct 2020 01:50 AM PDT

    The first video in the references below has a good (non-Google) overview of the issues with MediaStore for Android 11 - and how some apps are having to use a mixture of SAF and MediaStore to cobble things together.

    In this video they suggest keeping your files in your own folder - this way you avoid the 128 persistent permissions issue, as all the files within that folder get permission (if you have permission for that one folder).

    Still some issues with System Picker - as varies by manufacturer.

    They also resolve one question I had - whether one can create a folder within Music and other "shared storage" areas.

    They mention you can delete as well.

    We have had experience with MediaStore from some years ago - when it was really kludgy - sometimes a file would appear in MediaStore, sometimes not.

    Perhaps it has improved by now.

    Questions:

    • how easy is it to move a file from your own folder (within Music etc.) - and move it to a further sub-folder there. Is that instantaneous (as it used to be earlier when both source and destination were on internal storage) ?

    • when the Android 11 FAQ by Google on medium - https://medium.com/androiddevelopers/android-11-storage-faq-78cefea52b7c - Android 11 storage FAQ - suggests that fopen() can be used now - does that mean you can programmatically deal with file paths strings, adding on a suffix to point to a sub-folder (as you used to do before) ? That is, can one extract a file path from a Uri that MediaStore returns ? And then add on a sub-folder to the file path string and use that with fopen() ?

    rough transcript:

    2:19:30 minute mark

    128 persistent URIs ..

    when ask for 129 will have issue ..

    2:21:00 minute mark

    suggest keep documents inside own folder

    (so means can do sub-folder etc. !?)

    can hold permission to directory .. which easier ..

    can create directory

    can delete files

    2:25:00 minute mark

    migration ..

    2:28:00 minute mark

    major problems with SAF

    system picker provided by manufacturer ..

    problems with cloud based providers

    FileProvider for sharing with other apps ..

    they had issues with files ..

    migrated to MediaStore .. still have issues ..

    so still requesting legacy storage ..

    barrier is getting less ..

    also using SAF .. still using legacy storage sometimes (!?)

    1:09:00 - users not found user-friendly

    so had to use legacy ..

    Firebase Crashlytics Integration With Github

    Posted: 26 Oct 2020 06:03 AM PDT

    Good day guys,

    Hope you are safe and in good health.

    Can anyone here guild this fellow android developer on how to integrate firebase Crashlytics with Github.

    The idea is if there's any major crash on app, it should automatically get issued on our github repository.

    Thank you.

    Can't start rollout of an app due to app permissions error

    Posted: 25 Oct 2020 06:51 PM PDT

    I'm rolling out a new version of an app but for the first time needed to submit a declaration regarding the location permissions I'm requesting.

    I've submitted my declaration (as "no, I'm not accessing location in the background") and the page shows a green tick with a "Submitted" label, but my "Review and release" page is still showing it as an error, and the "Start rollout to production" button is disabled.

    I thought the review process was supposed to start by clicking "Start rollout to production"? Or is Google still reviewing the declaration, even though this release is still only a draft? It's been like this since last Friday.

    application publication deadline

    Posted: 26 Oct 2020 08:00 AM PDT

    Hello guys!

    About 2 years ago I published my apps / versions and it took a few hours. Today I need to make an app available, but it seems that the deadline has changed. Has anyone recently published any apps? What was the period of analysis?

    In-App subscription

    Posted: 26 Oct 2020 09:06 AM PDT

    Am I allowed to add subscription to the users as "Donation" feature. So, users will not get extra benefits, but rather, if they want, they can subscribe and support my work. App would still be the same for both subscribed and non-subscribed users.

    Is this allowed?

    What is READ_EXTERNAL_STORAGE permission needed for?

    Posted: 26 Oct 2020 03:04 AM PDT

    I noticed that an app is able to access any audio file on a device without having been granted the READ_EXTERNAL_STORAGE permission.

    I checked the official Android documentation and it's written in poor English:

    https://developer.android.com/reference/android/Manifest.permission#READ_EXTERNAL_STORAGE

    I was under the assumption that "External Storage" in Android is any storage that is not specific to your app. Am I wrong in that? Perhaps this permission is only needed to access sd cards?

    [DEV] Just launched my second diet app. It helps you lose weight every week

    Posted: 26 Oct 2020 07:53 AM PDT

    4 years ago I launched a diet app on Android that got me, the developer, these results: Before and After, in addition to working out as well of course. It is a calorie counter that focuses on losing weight over a week and updates your nutrition targets to keep you on track to lose 1 pound every week. That app has had some success on Android, so I wanted to launch it on iOS as well. Since I had to build the app from scratch for iOS anyway, I decided to build a new app using a cross platform solution (Flutter) instead. This worked out great, 99% of the code is the same between the Android and iOS releases.

    ​

    It's called Autopilot Diet and the key differences between this calorie counter app and the others are:

    ​

    • It focuses on your week as a whole. So if you over eat one day you can gradually make it up during the remainder of your week and still lose weight.

    • Your calorie targets are automatically updated at the end of every week based on what you ate, your activity and the weight you lost so that you don't plateau and continue losing weight.

    • You only need to weigh in once a week. The body does a lot of weird things over the course of a week, water retention, bloating, etc that can make you unmotivated if you step on the scale everyday, but if you look at your weight trends over the same day at the same time every week you will be a lot happier which will keep you motivated.

    • You can search for foods right from the home screen. As soon as you open the app you can start searching for food that you ate to log it. This sounds basic but is lacking from the major competition.

    • You can take a 24 hour diet assessment where you log what you normally eat, then your targets for your first week are based on that assessment. This provides a very accurate and realistic method for starting a diet.

    ​

    I just launched it on Google Play and would be happy to respond to your feedback and any questions in the comments below, thanks.

    ​

    tl:dr

    Launched my second calorie counter app that auto adjusts your calorie targets every week based on what you ate, your activity and the weight you lost so you don't plateau and continue losing weight. You can download it for free on Google Play

    apps supporting the full screen size/shape of the pixel 4 and 5

    Posted: 25 Oct 2020 10:33 AM PDT

    apps supporting the full screen size/shape of the pixel 4 and 5

    hi

    what do app developers need to do to fully support the screen size/shape of the pixel 5 (and partially the pixel 4)?

    i have a pixel 5 (and previously the pixel 4), and some, but not all, apps support using all of the screen, however some apps don't use the very bottom part, and others don't support both the bottom and the top?

    this is very jarring when an app ends up with a black section at the top and bottom of the screen.
    it's even worse when apps that play video don't support it. prime example being the plex app. i play a video, in landscape mode, and you end up with a black section on the left.

    see examples of two apps that have either one or both the "issues".

    Resume ideas for CS student to get internship or work as junior developer

    Posted: 25 Oct 2020 11:03 AM PDT

    Hello, first of all sorry, I know that there is subreddit for resumes. But I wanted get ideas from android developers. Anyway, rn I'm 3rd year software engineering student. I'm currently "working" as intern for my university but I'm not really happy with it plus I fell like it doesn't sound as serious as working for a company. I put 2 of my personal project on my resume. I thought adding university project would be bad idea , since my university is project based , I mean in order to pass you have to do projects on almost every subject and we have deadlines so the code is really messy and buggy to meet deadlines. And I also think of adding that I consulted other students about assingments , how to do some things etc. But since I have no proof, I didn't add.

    So basically, I know that my resume sucks and doesn't stand out. My personal projects not really usefull. I have no star on github(Idk how important it is for companies). Plus I already have HUGE disadvantage to work or be an intern on different countries since nobody would hire intern that isn't citizen.

    So here is my resume . I want to get internship for summer or get junior job in best case.

    I want to know what should I add to my resume?

    What kind of project would be cool to put on resume?

    What should I remove from my resume?
