    Weekly Questions Thread - July 27, 2020

    Posted: 27 Jul 2020 03:57 AM PDT

    This thread is for simple questions that don't warrant their own thread (although we suggest checking the sidebar, the wiki, our Discord, or Stack Overflow before posting). Examples of questions:

    • How do I pass data between my Activities?
    • Does anyone have a link to the source for the AOSP messaging app?
    • Is it possible to programmatically change the color of the status bar without targeting API 21?

    Important: Downvotes are strongly discouraged in this thread. Sorting by new is strongly encouraged.

    Large code snippets don't read well on reddit and take up a lot of space, so please don't paste them in your comments. Consider linking Gists instead.

    Have a question about the subreddit or otherwise for /r/androiddev mods? We welcome your mod mail!

    Also, please don't link to Play Store pages or ask for feedback on this thread. Save those for the App Feedback threads we host on Saturdays.

    Anyone received reviews like these that says the game/app is nice but vote 1 star? I'm just curious, are they bots or are they just being sarcastic? None of them reply when I tried replying to them. Flagging them or contacting support will not work as they didn't violate the comment policy

    For all who use Admob, don't target Android 11 (API 30) just yet

    Posted: 27 Jul 2020 04:08 AM PDT

    Why? Because it doesn't support it yet.

    I've tried to target Android API 30, and tested on my Pixel 4 R beta 2.5, and I can't see native ads, can't see interstitial ads, and probably also banner ads (this I didn't test yet).

    This is true at least for this version:

     implementation 'com.google.android.gms:play-services-ads:19.3.0' 

    You can try it for yourself if you wish. It will happen even with Admob's sample projects:

    https://github.com/googleads/googleads-mobile-android-examples/tree/master/kotlin/admob

    The error you will get when trying it out :

    0 - Internal error 

    I remember I saw similar issues on older versions of Android when they were on beta/preview, too.

    ¯_(ツ)_/¯

    Kotlin 1.4.0-RC Released – Kotlin Blog

    Posted: 27 Jul 2020 06:58 AM PDT

    Is there a reason that there's no native version of a collapsing/expandable layout?

    Posted: 27 Jul 2020 02:25 AM PDT

    And no, DrawerLayout and CollapsingToolbarLayout don't count, these are hard-wired to be window-related and toolbar-related (which is also window-related) respectively.

    While I use this version and it works fine, it doesn't really makes any sense to not have a native control/view for this since it's such a trivial functionality...

    How do I beat the '4+ years experience' requirement in job posting with building my own apps?

    Posted: 27 Jul 2020 02:37 AM PDT

    What sort of demo or published apps must I develop to beat this requirement? I am facing this situation where nobody wants to hire me if I don't have work experience, and the only way to have work experience is to work.

    I have a feeling that those tutorial apps I see online just won't cut it.

    How are some apps getting away with reward based ads allowing the user to cash out for real money?

    Posted: 27 Jul 2020 07:55 AM PDT

    So I've built an app that allows users to play digital scratch cards and lottery similar to Lucky Day and many others but with it's own twist that makes it unique. The problem I'm seeing is most ad networks seem to have something along the lines of the following in their terms of service:

    "Content, features or functionality that involve or promote transfers of in-game content or in-game currency into anything of monetary value, including cash, gift cards, etc."

    For example Unity Ads and Facebook Audience network both say something along these lines. Our application with Facebook Audience network got denied because of this. However I am using/testing many apps that allow a cash out for real money / gift cards that are showing ads from Unity Ads and Facebook Audience network amongst other networks that also prohibit this.

    I've gone through these apps, went to their developer page and looked up their app-ads.txt file to see what direct relationships they have to compile a list of ad networks to contact. I've sent many emails out waiting response, so far a few have responded not allowing this type of activity.

    So my question is, how does Lucky Day and others get away with this??

    [Google Play Console] Do crashes in Pre-launch report prevent publication ?

    Posted: 27 Jul 2020 07:00 AM PDT

    App has "pending publication" status (internal test track) and pre-launch report shows crashes on 3 devices over 11 tested.

    Do these crashes block the app in "pending publication" status or will it eventually get published ?

    AdMob vs Facebook Ads, which is better?

    Posted: 27 Jul 2020 06:13 AM PDT

    I know this has been asked a lot, but I've heard FB ads can only show ads to people that have facebook installed? Is this true?

    Also which do you think has the potential to earn more profit? And which network is more strict and tight? I don't want to go to a network that would get me banned for some stupid reasons.

    Beta users not able to review production release?

    Posted: 27 Jul 2020 04:07 AM PDT

    Anybody know why beta users can't review the game on play store after it's fully released on production? I removed all testers from beta, but none of my users seem to be able to review? Is this a policy on google's side?

    A way to call out PS4 controller buttons command using on-Screen buttons on Android

    Posted: 27 Jul 2020 04:01 AM PDT

    Sorry if I post it in wrong sub-reddit, but to be honest Idon't where else to post this. Soas title says I'm trying to find out is it posiible and if how to call out DUALSHOCK4 button command with on-screen button. For example I connect PS4 conntroller to my Android and press a one button on a controller (may be any △ or O )and then controller send specific command to device and device act it out how it can,so would it be possible to have a on screen button that when pressed device would think that same specific controller button command was send and would react the same way? The reason for asking is that there is a game that has specific command it can do but there's is no on screen button for that and it can only be called out with PS4 controller buttons I don't wanna pay tons of cash for a genuine PS4 controller just for two button on it.I you know where this kind of question would belong in another sub-reddit please link it in reply.

    I've created a small script to drop columns from the sqlite database

    Posted: 27 Jul 2020 12:06 AM PDT

    Hi guys,

    i stumbled over some limitations in the sqlite database and the alter table statement. So i decided to write a small abstraction layer for the Room Migration framework where you can drop columns and keep all your constraints and indices.

    Feedback is appreciated!

    How can i achieve "slidedown" fragment/activity with pull button?

    Posted: 27 Jul 2020 03:51 AM PDT

    How can i achieve "slidedown" fragment/activity with pull button?

    Hello, I do not even know how to google this kind of thing. I would like to implement in my App.. the "slide down" fragment/activity. I would like to drag some sort of button which would be visible at all times in main activity and which when dragged would come down with whole fragment/activity in which a lot of other options would be visible. What would be my possibilities in this case?

    Any help appreciated. Hopefully it is question about the design itself and it's not against the rules.

    State - Dragging in progress

    I'm struggling to resolve the conflict in having both:

    implementation 'com.android.support:appcompat-v7:23.4.0'

    and

    implementation 'com.google.android.gms:play-services-ads:19.3.0'

    does anyone have any ideas on how to overcome this?

    I plan on creating a simple app everyday for 30 days, in hopes of filling up my GitHub and becoming an aspired Android developer. My question is, what are some good resources to learn app development in Java?

    Creating reactive ui components with ReactiveComponents

    Posted: 26 Jul 2020 07:55 AM PDT

    Hey, my name is Max Gierlachowski and i am currently 21 Years old, attending university of technology of vienna.

    As I started android development I wrote big xml files that were hard to read and impossible to manage. After some time I realized that you could create custom/compound views and split up your ui into smaller reusable "Components". That introduced new problems, like managing the state of these "Components", rendering the state and so on. Today I present you my library "ReactiveComponents" which makes it easy to create these "Components", manage their state, listen to actions and render them.

    You can check it out on Github at the following link and read a little bit more about my design decisions and how to use it:

    https://github.com/MaxGierlachowski/ReactiveComponents

    P.S. I am developing android applications since I am 18 but this is one of my first libraries, if you have some suggestions and want to improve it feel free to contact me :P
