| Prevent an app being abused by UI Automator? Posted: 19 Jan 2021 07:39 AM PST Today I got banned in AdMob for "Invalid traffic concerns", and first I thought it's just Google being Google, however I also noticed a crash in Firebase Crashlytics with the UI Automator in stacktrace. Coincidentally, this crash pretty much matches with the time of ban, just about 1 day or even hours before it. I've never used the UI Automator, so that's definitely not me. All this made me think there's some malicious bot or competition trying to "DDOS" my ads. So I'm wondering if anyone knows how to detect that the app is being run from the UI Automator, so I can disable ads for example? Judging by the stacktrace, I thought maybe there's some way to hook into Does anyone have any experience with this kind of situations?

| Overlaying API data on GoogleMaps as animation Posted: 19 Jan 2021 08:42 AM PST What would be the best way, or is it even possible, to present API data - say weather or air quality/pollution data - as a real time overlay on a Google Maps map view. I'm hoping to build a route planner that will inform the user of any air quality or weather issues on their route. I've built a few route trackers with Google Maps by itself from tutorials, just wondering how I could go about augmenting in the next stage Many thanks [link] [comments] | ||
| What do YOU personally do to learn outside of work? Posted: 18 Jan 2021 11:26 PM PST I'm a junior dev and I'm currently doing google udacity courses to hone my android basics down. I'm wondering what do more experienced devs do to practice and keep their skills sharp. Should I really be expecting to code every day outside of work for at least an hour.. or is that overkill? Appreciate any advice! [link] [comments] | ||
| Use FFT and iFFT on real-time input audio and output the audio Posted: 19 Jan 2021 05:09 AM PST Hi everyone, I'm currently working on an app in which I'd like to do some FFT on audio input, then apply iFFT on it to be able to output back the same sound. This isn't the goal of the app, but it'd act as a test to see if the latency is acceptable to later on do some frequency or amplitude changes in real time. So far I have a little prototype which uses the Noise FFT library. The FFT seems to work great, but I'm a bit lost on what I would need to do to output the same audio I've got in the input after applying FFT then iFFT on it. Does anyone has an idea on how to proceed or been there already please? Thanks for your help. [link] [comments] | ||
| AdWords + AdMob is profitable in the long run? Posted: 19 Jan 2021 02:16 AM PST I started promoting my apps with AdWords and then monetize them with AdMob, I (almost obviously) end up earning less than what I spend. Is this always gonna be this why or optimizing well the campaigns and earning more users going to be ever profitable? [link] [comments] | ||
| Posted: 19 Jan 2021 08:26 AM PST Hi! I am creating a new web app to read data off of Google Fit API. Is there an easy way to load the Fitness database with some sample data, just to get off the ground? Any advice on that front is appreciated. Thank you. [link] [comments] | ||
| I have question on Facebook Audience Network's ad placement ID Posted: 19 Jan 2021 07:03 AM PST I have total 10 apps applied for Facebook Audience Network, and 9 of them been approved by Facebook. Can I use the approved apps' placement ID on the unapproved apps? [link] [comments] | ||
| How to know the store listing language of a certain app on playstore? Posted: 19 Jan 2021 06:37 AM PST Hi, As you may know Playstore offers to list an app in many languages. There are 7 English language options (En-US, En-GB, En-AU, En- IN etc.). [link] [comments] | ||
| Play Console app, error reply review Posted: 19 Jan 2021 05:08 AM PST I haven't been able to respond to reviews since this morning. Does that happen to you? [link] [comments] | ||
| Posted: 19 Jan 2021 01:12 AM PST I have recently been developing a middleware library that helps you to develop mobile applications, faster and easier than before. Finally it is live at https://topping.dev . This project started in 2012 to reduce time developing applications on android and ios platforms by creating a topping layer on mobile operating systems. All you need to know is how Android layout XML works and basic Lua or Kotlin knowledge. After developing it from time to time, I decided to make it open source. The project is in beta stage but most of the functions work. With the help of the open source community, I hope it will expand and grow and become the best of its kind. Also there are WPF and Web proof of concepts at github. http://github.com/topping-dev [link] [comments] | ||

| Posted: 19 Jan 2021 12:46 AM PST I recently added two of my apps to the Playstore. I added an Info-box in the loading screen which includes my email address for support. I also added a button with a Mailto link, so you can simply click on it and the app will open your mail client and add my email address, so you can contact me quickly. In the last few days I notice that I got around 5-7 empty mails to that email-address from Gmail addresses mostly. I though about a mistake of mine while including the mailto link, but I think it will not send an empty mail, it will only open the mail client. Or did in missed something for special android devices / operating systems? Is anyone else experience this empty mail thing? [link] [comments] | ||
| Not enough impressions for mediation Posted: 19 Jan 2021 12:14 AM PST Hi, I have like 800-1200 impressions per day, some days I have over 1200impressions. I have tried to integrate Unity Mediation into AdMob but after 3 days I didn't get enough impressions on the unity network, I got like 3-4-10 impressions, is it because I put an eCPM of like 2$? should I put something smaller like 0.1$?

| Domain of API calls made from a mobile app? Posted: 18 Jan 2021 11:32 PM PST Hi All, I've built a webapp for our company, and have been placed in charge of the mobile apps as well. Unfortunately I have very little experience in mobile dev, but Ionic/Capacitor does make it a bit easier. We want to use Vimeo for video hosting, and want to restrict the videos to certain domains, eg only accessible through www.example.com. Please excuse me if this is a non-sensical question, but I want to view the same videos on mobile, and am unsure if there is a way to set a "domain" for the app to call from? I've checked out the Vimeo API, and there doesn't seem to really be a clear solution or workaround. Many thanks [link] [comments] | ||
| Hakerrank android java recuritment Posted: 18 Jan 2021 10:22 PM PST Hi, i have been applying for jobs for Android. I have heard back from few place. And they seems to send this hakerrank test. I was just wondering if any one have given these test. I just wanted to know if it would be multiple questions or single question. The test have yime limit. Is there any preparation that would help?

| Question: Injection to DFM ViewModel with dagger/hilt Posted: 18 Jan 2021 07:55 PM PST Hi, our project is using the VIPER architecture, with each View having its own BUILDER and PRESENTER. The builder is created with a viewmodel and we inject all our dependencies there. The builder then creates the presenter with those dependency. We initially started off using KOIN as our dependency solution which worked relatively well, but decided to test migrate to dagger/hilt. The migration progress for the APP went relatively smooth as we were able to take advantage of the @ ViewModelInject that Hilt provided. However, I am currently stuck trying to migrate our dynamic feature model to the same structure as the rest of the app. I am able to follow Google's documentation and create a dagger component to be injected into DFM but i am having extreme difficulty getting the dependencies inject into the viewmodel without creating factory boilerplates for each view's Builder. Does anyone have any suggestions how i can dynamically create the viewmodels with the injection constructor without having to manually specify in each view? Here is our base screenview where we initialize our Builder/Presenter:

| What are the benefits if I build apps using native code instead of React Native? Posted: 18 Jan 2021 05:13 PM PST I'm building my apps in React Native and I kinda want to build my apps in their respective OS (IOS for Apply apps and Java(?) for Android). The thing is, I don't know where to start? I have strong experience with React, so RN comes naturally to me. I'm wondering if there are benefits if I make the switch. Like for React, there are states and such and that is what I am very use to when working with UI and dynamic data. How does app states work if I'm am moving to native code? [link] [comments] | ||
| Play multiple AAC Files in Android Posted: 18 Jan 2021 01:50 PM PST Hi there, I want to play multiple (about 3-5) AAC files simultaneously in Android. I need to decode it live so that I can change the volume, etc. I tried it using the MediaCodec and AudioTrack but the performance is miserable. I even tried to decode the files first and then play them but it didn't worked very well. Did anyone have some experience with that kind of audio processing in Android? I know Android and Audio is a difficult topic. [link] [comments] | ||

| Native ads vs Banner ads on Admob Posted: 18 Jan 2021 09:26 AM PST Native ads and banner ads which one pays more? I'm planning on integrating either of them on my article pages on my app. If I go with native, an ad will show at the bottom and top of every article. If I go with banner, it will be at the bottom in a fixed position and can be seen throughout the page. The articles are pretty long so users are going to spend a bunch of minutes on these pages and we already have a bunch of articles to integrated them in. Which route should I take and what advice do you have for me from your experience [link] [comments] |
