    Should I drop $4K on my game advertisement? Or will it be just money burnt on nothing.

    Posted: 01 Jul 2021 03:57 PM PDT

    I spent about $200 so far on Ads. 8K users 4.8 rating About 20% retention after a month

    50% acquisition for people who land the page. (Organic downloads)

    Numbers seem good BUT..

    Game is not making any income mainly because I'm aiming towards poor countries because of the low cost of Ads.

    My strategy is to get 100k users by dropping $4k on advertisement So that after getting all those users the organic downloads from rich countries start rolling in.

    Is this a good strategy?

    Question about naming my mobile game

    Posted: 01 Jul 2021 05:21 PM PDT

    Hey everyone!

    So I'm developing a game and I was thinking to name it "Don't touch the wall". I know it's not a unique name, but it fits exactly the description of my game. I searched this title on playstore and I found 2-3 games using this name.

    Would that be a problem, legally speaking? Can these type of titles get a trademark? Do I need to contact with google for clarification?

    Thank you in advance!

    Device Verification methods?

    Posted: 01 Jul 2021 03:27 PM PDT

    I'm trying to build something that requires a device an authentic device(not emulator) and not rooted. I know about device attestation by Google and will use it I'm just wondering if there are other methods just to be thorough.

    Were Support libraries e.g. v4 all replaced by AndroidX?

    Posted: 01 Jul 2021 01:57 PM PDT

    I'm working through Head First Android Development, but in one chapter it talks about support libraries and it doesn't seem to work as it says in the book. Is this due to androidx replacing them or something?

    Best way to pass down parameters to Composables?

    Posted: 01 Jul 2021 09:41 AM PDT

    I'm kinda new to Jetpack Compose, still trying to figure out the best practices. At first I saw Google assumed it would be a good idea to pass down parameters encapsulated in custom *ViewState data classes. Unfortunately as my Composable call chains were getting longer and longer, I ran into a problem where about the 4-5 function in the chain suddenly needs a ViewModel instance to call some functions on when i.e. a button click happens.

    How would you counter this? Injecting a ViewModel into every Composable kinda defeats the whole point of ViewState classes in my case and it also smells like bad design to me. I also thought about adding lambdas to the ViewStates, but then it means the "upper level Composables" (the MainScreen for example) will basically know about the "Composables deeper in the call chain" (a list item that needs a lambda for a click action). I wonder if that violates some rules related to data hiding.

    What percentage of you admob revenue is invalid traffic?

    Posted: 01 Jul 2021 06:34 AM PDT

    For the past two month one of my apps has had very good growth, which has made my estimated earning go up.

    I got excited because my record has been broken two month in a row.

    The annoying thing is that my invalid traffic is a significant part of that estimated earnings amount even though I have not been developing or testing any of my apps (I use my own apps once in a blue moon).

    This is how much my invalid traffic has been for the last two months:
    May 2021: 25%
    June 2021: 20%

    What are your average invalid traffic amounts?

    How to inspect http request from phone to server

    Posted: 01 Jul 2021 06:27 AM PDT

    I want to inspect http request made from my phone to my server backend. The reason is, that it takes some unexpected long time to open a website what I have set as startpage in my browser.

    It's the same for Chrome, Samsung Internet and Firefox. I have set the same startpage in all browsers. If the browser is closed and I start them, it takes some seconds to load the page. I would like to know why it takes that long time. If I inspect the access log from the webserver, I can clearly see that from first request to send the result, it takes only 100ms. Something must prevent the browser from sending the request to the webserver.

    I have changed the DNS server on the phone, but this doesn't change the long running request. Also requesting the ip, instead of the domain didn't change the time.

    If the browser is open with a blank page and i request the url, the page opens quickly within 150ms.

    Any ideas?

    I would like advice from the members here on the subject of publishing and having an app searchable in the Google store.

    Posted: 01 Jul 2021 09:59 AM PDT

    If you were a developer and you developed a one page app with minimal functionality for something such as a calculator and called it "MyRedditCalc". If you then push that to the Google store. Assuming it passed the reviews/checks, how long do you think it might take before that app was searchable in the two stores for a person entering "MyRedditCalc" as a search criteria?

    Keeping shared state between items of viewpager

    Posted: 01 Jul 2021 09:04 AM PDT

    Hey guys, I'm trying to build a gallery view similar to the one in Google Maps. Every image has an overlay description that should be hidden when user taps on image. I'm having issues maintaining a consistent state between photos in the viewpager. Basically if a viewpager has already preloaded next item and populate it's viewholder the view doesn't get an update when user taps in an image. So it can go from a picture with hidden overlay, to a picture that's showing the overlay.

    I'm thinking calling notifyDataSetChanged() may solve this but I'm worried about performance impact on this, since it'd need to update every other item in viewpager.

    Any ideas in how can I tackle this?

    Hi everyone,

    Have you ever integrated Google Fit into any app other than the health and fitness category? If yes, did you get approval from Play Store?

    5 best screenshot makers for google play 2021 (Paid + Free)

    Posted: 01 Jul 2021 08:51 AM PDT

    Here, I made a case why you don't need screenshots until at least 4000 downloads per month.

    But if you get more downloads or if you don't want to listen to my advice.
    Screenshots makers are a good way to make some great-looking screenshots.

    Let's get into it!

    Unable to build the project due to androidx.core library mismatch

    Posted: 01 Jul 2021 08:08 AM PDT

    Hey,
    I was trying to make some changes to my existing project this morning but I am unable to generate the build which was working till yesterday.

    I am getting an error that says the following,

    The minCompileSdk (30) specified in a dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties) is greater than this module's compileSdkVersion (android-29).

    Dependency: androidx.core:core-ktx:1.7.0-alpha01.

    I am still using the targetSDK as 29 and haven't configured it to be 30 yet and also, I am using Facebook SDK and Admob SDKs for various reasons. Anybody else facing this issue lately?

    QuiteRoute - navigate to developer options and other activity easily

    Github: https://github.com/Jintin/QuickRoute

    Hi, don't know if there's anyone has the same problem as I have, but as a developer I often need to toggle the config in developer options so I made a tool to open this page quite easily as you can see in the below gif.

    https://i.redd.it/asrrfib6ci871.gif

    And beside of this main feature, the app also provide the functionality to open any exported Activity with the extra you defined, example here:
