Ads are now able to bypass Google Play to install apps WITHOUT user consent. Digital Turbine DSP seems to be the one enabling it.

We recently received a couple of upvoted reviews from upset users reporting an app had been installed on their device without their consent after watching an ad and tried to close it:

We managed to get in contact with one of the affected users who kindly sent us some screenshots of the ad in question:

A quick check of that app's Google Play reviews (https://play.google.com/store/apps/details?id=com.home.weather.radar&gl=ES&showAllReviews=true) shows lots of users complaining, amongst other ugly stuff, about the app being installed without their consent confirming the reports from our users were genuine.

After talking to a couple of our ad provider Account Managers, we were told this is a technology from DSP Digital Turbine (who recently acquired Fyber) who has managed a way to avoid Google Play interaction to install an app. This may be the patent related to it: https://www.freepatentsonline.com/y2019/0265958.html.

This seems like a serious security vulnerability and the perfect mechanism for unscrupulous advertisers to install malware.

What bug made you give the Patrick Stewart "WTF" gesture?

Posted: 10 Oct 2021 12:50 AM PDT

For reference

https://preview.redd.it/mznnm0nmjks71.png?width=620&format=png&auto=webp&s=ec5792c6f2ce5366c46081b9f2564a9af6d56911

There have been many for me, but my newest one is with FileObserver. Apparently, LG devices (Android 9 and lower) do something weird with this class, and if you call startWatching() on multiple FileObserver objects but in different threads, you get a ConcurrentModificationException. To elaborate, if you do something like this:

runBlocking { repeat(10) { val file = File("somefile-$it").apply { createNewFile() } // Assume these are different files // Create the file observer object in one thread val fileObserver = object : FileObserver(file.path, FileObserver.ALL_EVENTS) { override fun onEvent(event: Int, path: String?) { // Doesn't matter what this is } } // Call startWatching() in a different thread launch(Dispatchers.IO) { fileObserver.startWatching() } } }

This will throw a ConcurrentModificationException. You have to synchronize on startWatching() to prevent it, and only on LG devices with Android 9 and lower... And yes, there is no way to change what files a FileObserver will monitor once it's created.

What about you all? What random Android crap earned the "Picard gesture" from you?

Does anybody else have "Great App" 1-star reviews problem ?

Posted: 10 Oct 2021 03:55 AM PDT

My app rating is 4.6

80% are 5-starts

10% are 4,

2-3 stars are negligible

8% are one star.

My issue is that about half of the 1 star reviews contradict the review body with likes of :"Excellent app" - 1 star. "I want to the thank the dev personally" - 1 star

remainder of the 1 star are without review

How this happens ?

- confusing stars ui widget ,

- My app is in right-to-left language also making the stars widget more confusing

I think google with all it's AI powers should give those reviews less weight or better gently notify user when he enters rating that contradicts his positive review.

In the past I replied to those by-mistake one stars saying "Thanks for the kind words, but you rated with 1 star"

Many fixed their rating but this is tiresome and looks needy and many dont bother if I reply a week later.

PS. There is a HUGE conversion rate between 4.9 and 4.6 apps

Developer Salaries

Posted: 09 Oct 2021 05:23 PM PDT

Hi all. Apologies if this kind of discussion isn't allowed here, please point me to a better venue if so.

Basically, I'm currently being paid £35k as a software engineer in the UK as the primary developer on my project. I've been here for three years, in which time I've taught myself Android and developed from scratch four apps from customer requirements through to design, testing and documentation.

Recently in the past few weeks we've hired two new guys straight out of university who don't know a thing about android or proper software work (neither had ever used git or java/kotlin). Not that it's their fault of course, but it does mean that I am de facto mentoring and training them on basically everything as though I were a senior engineer.

My salary hasn't increased for a good while, so I recently asked for a raise in light of my increased responsibility and they offered me £37k. I was anticipating more like £45k or more, so this was quite underwhelming.

My question is: what kind of salary would you expect for this kind of role/experience? And do you have any advice for career/salary progression in general?

Is anyone facing low impressions in Admob?

Posted: 10 Oct 2021 05:17 AM PDT

Hi, I've been using admob and have been getting around 40-50k impressions per day and it has dropped to less than 100 today. The active users haven't dropped. There was a warning to add app-ads.txt which I fixed today after seeing these low impressions. The ads requests haven't dropped, only the match rate and impressions have gone insanely low Anyone else facing the same issue? Is it due to the missing app-ads.txt?

Android coldstart profiling

Posted: 09 Oct 2021 10:48 PM PDT

Hi,

I want to profile a release version of our android app. Try to use tools such as perfetto and android studio profiler.

However, android studio profiler seems to be working only on debuggable builds. Also, perfetto does provide the flamegraph but provides little insights in the call graph, etc

Does anyone know a good tool for profiling, which also provides the following:

Network time spent during startup
Disk activity
Call graph
Pie chart to present more information on Hot processes and % of time spent in CPU/Network/Disk

Thanks.

AdMob app-ads.txt not being crawled?

Posted: 10 Oct 2021 01:52 AM PDT

The only option Google is giving me to contact them for this issue is a community post that has no responses even after a month of positing hence posting it here.

My app-ads.txt has been live since. I don't know, more than 3 months but AdMob does not seem to crawl it. I also checked robots.txt and it seems fine to me.

I have checked countless times on the Play Console that our website has been properly mentioned in the Store Listing contact details but still no luck.

Over at SO, people have given up and moved on from this issue.

Any help?

Can we parallelize creation of ui object?

Posted: 09 Oct 2021 09:49 AM PDT

In my recent interview i was asked a question if we could make ui from background thread. I was sure that was not possible, but then the reality breaks apart, seems i have travelled to different timeline as interviewer told me yes we can by attaching looper to background thread and make thread always running just like mainthread. Is this true and if yes can guide or cite some examples or tutorial for the same. This keep waking me at night.

Poor Resource Utilization During Build

Posted: 09 Oct 2021 08:04 PM PDT

I'm compiling my app in debug mode using Flutter's SDK. I have an 8c/16t Ryzen 3 5800H, 32GB RAM, and 2TB nVME SSD. CPU isn't throttled and can maintain 4ghz on all cores during 100% load under stress.

While compiling my app, I noticed that there are two main processes involved: OpenJDK Platform Binary, which doesn't exceed 50% in CPU usage, and dart.exe, which appears to only utilize a single thread.

Build time is still around 30 seconds. Not terrible, but it appears to be a software bottleneck.

gradle.properties:

org.gradle.jvmargs=-Xmx4536M android.useAndroidX=true android.enableJetifier=true org.gradle.parallel=true org.gradle.daemon=true android.enableBuildCache=true org.gradle.caching=true org.gradle.workers.max=16

Obviously it's not a huge ordeal, but if there is a way to use 100% of available system resources, as opposed to <50%, that would be ideal.

Thanks

Can we (and how can we) implement ViewModel in Android without extending androidx.lifecycle.ViewModel class since ViewModel is not just a concept in Android but in general software development?

Just asking out of curiosity. Is my question even correct?
