| Scoped Storage - File Browsing Issue Posted: 20 Apr 2021 07:58 AM PDT Hi everyone, Yet another Scoped Storage Issue! Possibly! My app used to create a folder under "/storage/emulated/0/<myfolder>" to hold files. Now with the scoped storage, I'm forced to migrate the entire thing to "/storage/emulated/0/Android/Data/<my app package>/files/", which is sorta fine, but..... A functionality from my app is to be able to browse and upload files from the system file picker. This included the files that I used to create under "/storage/emulated/0/<myfolder>", which I was able to see on the system file picker UI. But now, since I'll be migrating, I should be able to pick files from " "/storage/emulated/0/Android/Data/<my app package>/files/<myfolder>" which I'm not even able to find in the file picker! All I can see is "/storage/emulated/0/Android/". If I can't browse to MY app specific folder that MY app created, then what is the whole point!?? Am I missing something or is it something everyone is facing ?? Any help/insights would be appreciated! [link] [comments] | ||

| Posted: 20 Apr 2021 08:23 AM PDT I'll try to keep this post as short as possible. Like many here, I did the corporate job for a while but after some time I grew tired of it. In Jan 2020 I made the decision of using all my savings to keep me afloat for one year while building the next version of Memorigi, my todo-list, calendar, and reminder app. I wanted to create something way better than the status quo. So, I gave my two weeks notice, moved back to Costa Rica, and started working on it day and night for the last year and 3 months. No vacations. No holidays. Just work. Fast forward to today. A few weeks ago Memorigi surpassed the 500000 downloads barrier and today I'm officially releasing Memorigi 5.0 on Android and Web. Here are some takeaways that might help other fellow devs trying to do something similar.
I hope you find these useful. Now, for the free 1-year Premium membership I want to do something with a ROI for this sub. Here is the only rule to participate: Make a top comment here asking something Memorigi-Android related that you think the answer could benefit other developers. For instance, you could ask about the architecture, its design, the tech stack, the journey, how I managed to get 500000 downloads, etc. Just, please don't ask about sensitive information. At the end of the day I'll handpick the 10 most valuable comments and DM their Premium memberships. Bests! R TL;DR; Quit my job, used my savings to create the next version of my app, worked day and night for over a year on it, learn some valuable lessons, don't know how it's going to turn out.

| How can I use Firebase Dynamic deeplinks for Facebook ads ? Posted: 20 Apr 2021 05:44 AM PDT I want to run Facebook ads for my app using Firebase Dynamics deeplinks, but when in insert the link I get the following error : App Links Field Invalid:: The described URL doesn't have app links HTML meta tags. Use a different URL or a mobile deep link (eg 'mobileapp://). (#1487904) Is there a workaround so I can still use the current dynamic deeplinks ? [link] [comments] | ||
| A fragment -> auth flow-> bottom navigation w/ Navigation component/jetpack Posted: 20 Apr 2021 04:26 AM PDT I am looking for recommendations to a good resource to code along to such as a tutorial or articles or series of articles. My quest involves building an app that involves landing page, login/register fragments after which I am taken to a bottom navigation screen with 3 tabs. Each tab governs its own back stack. I am already familiar with navigating fragments from one screen to the next. I just want a resource that demonstrates moving from a home fragment to a screen that has tabs with their own navigation stacks. Prefereably also demonstrates conditional navigation(if logged in, skip login fragment) [link] [comments] | ||
| Posted: 19 Apr 2021 10:07 PM PDT I recieved an warning message which says, We've detected that your app contains the requestLegacyExternalStorage flag in the manifest file of 1 or more of your app bundles or APKs. I am targeting android 10 and use requestLegacyExternalStorage = true

| OAuth Verification Request help? Posted: 19 Apr 2021 05:35 PM PDT Hi, I'm trying to add cloud saving to my game with the google play games services. From the google cloud platform I completed all steps and set the publishing status to production. It asked me to verify ownership of my website, and with that done, they sent me an email telling me to make sure I've completed all the rerquired steps. I'm wondering, what OAuth scopes for google APIs do I need for just cloud saving and achievements? And what's all that about I have to make a "... demo video demonstrating the OAuth grant process by users and explaining, in detail, the usage of sensitive and restricted scopes within the app's functionality for each OAuth client belonging to the project."? Any help would be greatly apreciated, I'm kinda stuck. [link] [comments] | ||

| Whats the new app review time? Posted: 19 Apr 2021 02:30 PM PDT I've submitted ever first app over 3 days ago for review. I did a closed testing, open testing and internal testing. They all say active but I cant see it in the play store I also for some reason can't choose a pre register track. Is this normal? This is the first app am releasing so I dunno how this works really. How pong does it now take for an app to be released thanks to covid [link] [comments] | ||
| Premature optimization is the root of all evil Posted: 19 Apr 2021 12:06 PM PDT I was struggling with CameraX for a few hours, wondering why the heck the analyze function was only called once. Yes yes I know, I have to call ImageProxy.close() at the end, and I did. But it still failed to work. Thing is I had a try-catch block right before the ImageProxy.close() call. After trying several things and being incredibly frustrated, I finally put the ImageProxy.close() call within a finally block, right after the try-catch and........it worked. I couldn't figure out why the heck that was required. And then I saw the unnecessary return statement that I had added inside the try as an optimization. Basically I was using MLKit's Barcode Scanner, and if no barcodes were detected, I was returning. And this caused the ImageProxy.close() call to not be invoked. I've made this mistake before, and it cost me a few hours when I should have been done with this task by now. So remember, don't be a smartass, sometimes, optimize later. Does anyone else have stories about premature optimization? [link] [comments] |
