    Looking for maintainer/contributors for Android PhotoEditor library

    Posted: 17 Feb 2021 03:12 AM PST

    Hello All,

    3 years back I open-source and a photo editing library for android which was inspired by PhotoEditorSDK and Imgly Android App. Since then I am maintaining this project solely in my free time. Along the way, I found few collaborators who help me to fix minor and major bug fixes (Thank you for the fixes :)).
    Since it's been used by a lot of developers with around 200 thousand downloads, a lot of issues, questions are being raised on the repo.

    Currently, I am not able to find an ample amount of time to maintain this project. So now I am looking for a maintainer/collaborator for this project. If anyone who is interested can start the discussion here Or [email me](mailto:burhanrashid5253@gmail.com) for more details.

    Is anyone else bothered by Android Studios' Windows Icon?

    Is anyone else bothered by Android Studios' Windows Icon?

    The icon enclosed in a white circle just really doesn't fit in next to most other apps, and the actual icon is so tiny that I can't even make it out on my taskbar. I was able to find a png of the icon itself and change it myself and it just looks so much more friendly next to my other applications. Why the strange design choice?

    I made a Pokedex in Android with an accompanying back-end in NodeJS!

    I made a Pokedex in Android with an accompanying back-end in NodeJS!

    PokeData

    Recently, I started learning Android. This is the application that I made after about a month and a half of experience, as the culmination for a university course. It is open source with a GitHub repository.

    ​

    Features

    • List of all current Pokemon up to Generation 8.
    • Search Pokemon by name, with ability to find Pokemon with partial search entries such as just "chu".
    • Detailed view of a Pokemon with the Pokedex entry and the evolution line, which can be used to navigate to a member of the evolution line.
    • Pressing on a Pokemon's sprite in the detailed view displays the shiny sprite.
    • Log-in and register with Firebase.
    • Favourite Pokemon tracking with Firebase.
    • Responses from the back-end are cached for speed and online usage. This allows the application to work offline as well, except without favourites.

    Info

    This project was made for a university course during a 14 week long course on Android. I learned a lot while working on practice assignments and had to make a capstone project at the end. A capstone project is a culmination of theory learned during a course that is then applied to create a final project.

    Originally my plan was to use PokeApi to get the data for the Pokedex. However, PokeApi is quite overloaded and it is very slow. I tried to host it on my own computer and use that, but the problem was that this does not provide a permanent solution for the application, as it would need PokeApi every time its ran on a different computer. Furthermore, PokeApi was not very fast even when running it locally. I'm not really sure why but each request took almost 200 ms sometimes. This really stacks up when you are paginating it with even 20 Pokemon per page. Also, the way PokeApi was set up would require me to send 2 requests per Pokemon on the browsing page already. With slow requests, an unreliable API and two requests or more needed per Pokemon it just did not seem like a good solution.

    Therefore, I created my own back-end using NodeJS. It has a tool built-in to populate a local database using PokeApi. What I did was run PokeApi locally, build the database with my tool which takes about 5 minutes but it does not matter since it only has to be done once and the user would not notice this slowness and would instead experience a smooth application once the back-end is running.

    Missing Features

    There were some features I would have liked to add, but did not because I did not have the time for it. In the future I may return to finish these features.

    • The display of Pokemon evolutions currently does not support multiple evolution branches. It only accounts for Pokemon that have a linear evolution line. It would be nice to somehow display this in a different way where the other evolutions of a Pokemon can be seen.
    • Even though the back-end supports filtering on color, weight and height, the application currently does not support filtering using these parameters. The only thing needed to do this should be some UI with logic to send different API requests.
    • It would be nice to view other users' profiles with favourites and have some kind of friend adding system as well as chat. This is not really a necessary feature, but it would be educational to implement this.
    • Not every edge case is handled. A lot of bugs are handled gracefully, but some things are not. For example, there are no notifications about being offline or online. A list of issues could be compiled to fix this.

    Video

    I have also recorded a video that shows the features of the application.

    Feedback

    I would really appreciate some feedback on the code if anyone would like to look through this project. I think I did not use a lot of best practices and some things could have been done better.

    App upgrade failure in Google Play

    Posted: 17 Feb 2021 05:27 AM PST

    Recently I noticed that users of my app have been leaving reviews that they are not able to upgrade the app. They are getting a failure message from google play while update is being installed. Anyone else seeing this issue?

    I am not able to replicate this behavior on any of the test devices with same OS and App version as users have. Users have tried clearing cache, uninstalling the app and still the same issue.

    Can you develop android apps without having to use Android Studio?

    Posted: 17 Feb 2021 08:02 AM PST

    I've been interested in creating a android app for quite some time now. I've been planing on picking up a new language like Java or Kotlin so I can develop android apps, but the need of android studio is crushing that dream. My laptop is very low specs and it can't run Android Studio without dying lol. Any help?

    Need help

    Posted: 17 Feb 2021 08:00 AM PST

    So basically i am 16 years old and i have a play store développer account. I have an app with 100k downloads on it. After a long time i recieve a notice saying my payment is on hold and a notice saying:

    "Brazilian law requires payments providers that sell to users in Brazil to verify the identity of their customers and withhold payments to customers until they have completed the verification process. To comply, you are required to complete all of the following steps to verify your account. Failure to provide the requested information will result in your sales being suspended.

    Once all your information has been verified, you will receive an email confirmation. Please bear in mind that we may need to request documents to verify your business type, so be sure to select the option that is legally accurate for your business."

    So basically if i give them my id they'll know that i am under 18. I am doing this with my parents permission but now i am afraid that if i give them my id my account will be suspended so will my app.

    What should I do?

    [UPDATE] App suspended for a reason I cannot understand

    Posted: 17 Feb 2021 01:52 AM PST

    Hello again!

    A mod deleted the post in order to make a new one that provides additional information about the app. Gladly I saw today that the app got activated again! But to be safe I have to put a new icon I guess. Does anyone have a new idea about a new app icon and how to avoid a possible duplicate ?

    The strage thing is that one response from google told me that my app impersonates this app: https://play.google.com/store/apps/details?id=com.falcon.applock

    But the other response told me that app got reinstated (activated) again. I guess this response had more value haha.

    Im attaching the responses aswell. The first one is from an update rejection appeal and the second one is from the suspension appeal

    Gradle decompiling an unrelated file after removing LeakCanary.

    Posted: 17 Feb 2021 07:14 AM PST

    I tried opening a question in SO already, to no help: https://stackoverflow.com/q/66234852/11214643.

    I was trying to clean my code, as the LeakCanary Library was exposing some android annotations that I was inadvertently using "@NotNull" instead of "@NonNull".

    As I finished cleaning the classes (like 30+ classes...), I removed the library entirely (just commenting the line):

    // debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.5'

    Then the main .kt file of an unrelated library (entirely written in Kotlin) called CalendarView.kt https://github.com/kizitonwose/CalendarView.git (a nice customizable calendar) becomes CalendarView.class

    And the bellow message appears on top of the now turned class.

    // IntelliJ API Decompiler stub source generated from a class file // Implementation of methods is not available

    And now the code is not working.

    I have no idea, what's happening here...

    Interstial ad (Admob) between bottom navigation fragments

    Posted: 17 Feb 2021 03:00 AM PST

    Is it against the policy to load interstial ad when BottomNavigation item is selected? I'm making sure that only after 3 clicks the ad is shown, just wanted to get the general idea that if the full screen ad can be shown while switching fragments from bottom navigation.

    Desuguar support java.util.concurrent.Flow?

    Posted: 17 Feb 2021 02:48 AM PST

    I'd like to use java.util.concurrent.Flow for a library i'm creating, it's a fundamental API that Android began using too, but it isn't available until Java9/Android 30.

    Are that class/those interfaces "desuguared" and usable on older Android?

    If not, can i add it to be "desuguared" myself somehow?

    Choosing between library and custom view/code

    Posted: 16 Feb 2021 11:52 PM PST

    Hi. I am not sure if this has been asked before , but i tried to make a google search with these keywords and could not find any significant opinions.

    What are the factors you consider while choosing to use a library in your code over writing a custom view / class/ layout ? What are the advantages and disadvantage of choosing on over the other?

    Some of my personal deciding factors are usually :

    1. Choosing library over writing my own class : if library is getting updated more frequently with respect to changing tech, using latest best practises, has active development and bug solvings, reputed, etc, i will choose library over writing a custom class
    2. Creating a custom code over using library : if library is not compatible with my gradle config/if library is too large/providing more features than required/hasn't active maintenance, etc i will be writing a custom class over library

    What other points are important to consider?

    Configurable Background with widget/seekbar

    Posted: 17 Feb 2021 02:58 AM PST

    I've tried searching Reddit and Google and nothing came close to what I would like to implement. Trying to add a configurable widget with an app I'm building and I would like to be able to change the background opacity using a seek bar. Are there any good open source projects or tutorials that have implemented this feature? Thank you in advance!

    Contact AdMob Account Manager

    Recently I was contacted by Facebook Audience Network in order to discuss switching to App Bidding. They have enabled App Bidding on their side and they told me I have to contact my Admob Account Manager to enable App Bidding for Admob (it's also stated here).

    Does anyone know where can I contact my Account Manager? I searched for it and found literally nothing.

    I assume I have access to an account manager (8M monthly impressions across all apps)

    How to handle NavigationBar Apps: Fragments or Activities?

    Posted: 16 Feb 2021 12:49 PM PST

    I have a quick question regarding apps with BottomNavigationBar: Are Apps with BottomNavigationBar (e.g. Instagram or Reddit App) completely based on Fragments and just one MainActivity ? I want the UI for my App to be similar, with the BottomNavigationBar visible at all time, but I'm not sure If I should use fragments only.

    Thanks in Advance
