| Thoughts on whether to use enums or not Posted: 05 Oct 2020 03:24 AM PDT I have been reading up on enums and their application in android development. specifically kotlin android development. I have seen thoughts and counter thoughts. But the issue is that most of the arguments i have seen are as far back as 2- 5 years ago. I would love to hear up to date thoughts on whether to use it. as well as links if possible. Thank you all in advance [link] [comments] | ||

| Signal processing in c++ via JNI Posted: 04 Oct 2020 04:07 PM PDT I'm an ML engineer that works with sensor data and I want to make a demo of my company's software in an android app. We export our models to header files in c/c++, where we run feature-extraction + prediction. I'm envisioning a pretty simple GUI with the sensor data plotted in one frame and its classification in another. Usually I write these apps in matlab for a laptop/tablet and latency is sometimes an issue due to trying to plot a lot of data points (high sample rate) as well as matlab having a lot of overhead -- but the "SensorsLab" android app plots real-time data from 8 physical sensors so I think what I'm attempting is do-able on a phone. My entire experience with android/java is one personal project where I passed each camera frame to a c++ function for image processing in opencv via JNI, so I have a few questions:
Any feedback is much appreciated - thanks! [link] [comments] | ||

| Posted: 05 Oct 2020 01:44 AM PDT Ever thought what prevents us from tricking the system into hiding the soft input keyword which is being used by some other application, or releasing a wake lock acquired by another application. This blog tries to cover some of Android's security internals. https://proandroiddev.com/binders-in-android-part-1-e875daeb762f [link] [comments] | ||

| How to overlap scrolling content over AppBarLayout in CoordinatorLayout AndroidX / Jetpack? Posted: 05 Oct 2020 07:01 AM PDT Hi. In my android app I need to overlap scrolling content over appbarlayout as given in this image https://i.stack.imgur.com/Ba4h8.gif setting layout_overlapTop was an option that worked in older versions of the design library but does not work now. Any ideas? [link] [comments] | ||
| Can someone point me in the right direction? First time dev Posted: 05 Oct 2020 07:01 AM PDT Hello all, I'm looking to make a very simple multiple choice question bank app for Android. The app would consist of questions with 4 answers for each. There would be several categories. Ideally, real time feedback would be displayed if correct/incorrect and a percentage would be given at the end of a category. Hopefully, the app would also be able to remember progress on a certain category and also have a "review category" for incorrectly answered questions. This app is primarily for me and I think it'll make for an interesting passion project. Problem is, I've never made an app before. I don't have any proper experience, I was just hoping to see if someone could point me in the right direction as I have no idea where to start. I like to consider myself as being proficient with tech and problem solving, I have enjoyed coding courses in the past. Would what I require be difficult to do? Can I find coding templetes as something to work from? Thanks for any input, it would be greatly appreciated. [link] [comments] | ||
| Is it OK to put logic in Dagger Components ? Posted: 05 Oct 2020 06:59 AM PDT I recently stumbled on a PR where a dagger module was being provided based on a feature flag check. So in the Module there was logic to check and based on it, the correct service was provided. Is this approach alright or is it preferable to have Dagger modules laid out without dynamic modules.

| How to check if 5G network is supported by the device ? Posted: 05 Oct 2020 06:39 AM PDT Hi so i want to check if the device that my app installed in supports 5G network i don't want to know if it is connected to it but i just want to know if it's supported i looked for an api to do that but since I'm new to coding i couldn't find anything useful for me i have a solution but it's not effective which is get the cpu name since there's only few cpus that support 5G now, but as i said it's not effective any help please [link] [comments] | ||
| Detect s-pen input on samsung tablet in order to make straight lines? Posted: 05 Oct 2020 06:05 AM PDT So I hate the fact that Onenote on android is really limited. I have this Samsung tablet on which I take notes in class with the s-pen. I would like to programm an app that at the end will be a circle over the interface like others apps already do. Simply you press the circle and till is pressed you can draw straight line. I already looked for a solution but I didn't find any. So I was thinking that I need to detect the input of the pen and write some code where I define x and y that is the position of the start, etc.(I didn't think about this yet but it's okay It will be the funny part anyway, right?lol). I have experience in coding and I would like to put this project on the cv.. What do you suggest? It is possible or I am understimate everything? I saw Ionic as a framework that can be a good option but still I don't know how to somehow detect the s-pen input. Thank you [link] [comments] | ||

| Managing Many Android Phones for Development Posted: 04 Oct 2020 09:23 AM PDT Hi there, We are working on an app and so far we have 4 different Android phones for development. I guess the number will grow to 10-20 handsets within the next 6-9 months. My question is how do you or other companies manage all these Android phones from the very beginning once you get a new phone (and you need to sign in with a GMail account), do you do one GMail account per phone or do you use one GMail account for all development phones? I came across Google's cloud identity and Microsoft's Intune for "Endpoint Protection" so you can manage all these devices and you pay per device but I don't know if that's a good option. Here is what I want to do exactly:
I guess the main thing that I'm after would be not creating an account for every phone and having a dashboard to remotely control all the phones. By the way, we are using Office365 Thanks! [link] [comments] | ||
| How can I let my Android device connected to the Internet by USB-Ethernet module? Posted: 05 Oct 2020 01:57 AM PDT I have bought a development board that runs Android 4.4.2. But it have only supports Wi-Fi and no Ethernet .Now I want to use it as Miracast Receiver,use WLAN is a bit slow and unstable. So I bought a USB to Ethernet module.I can use it on my Windows 10 computer and Android 7.0 tablet without any drivers. But when I plug it into the development board,it cannot recognized the module. So how can I let the development board connected to Internet via USB Ethernet module?Do I need some drivers , thank you. [link] [comments] | ||

| Posted: 04 Oct 2020 03:36 PM PDT Hello, Do you usually wait to promote your apps (e.g. ads, promo giveaways) at specific occasions like Black Friday, Xmas, etc? If yes, do you find it worthy? Thanks! [link] [comments] | ||
| Need advice on running WASM on mobile devices Posted: 04 Oct 2020 11:50 PM PDT I have a game that I developed in Go that compiles to WASM and runs nicely my browser. It's fairly simple, and only uses the space bar and directional keys. I would like to be able to run it as a mobile application, but I am not sure how to go about getting input from the device or if it's even realistically possible to do. The thing I am most confused about is getting input from a touch screen to interact with the game instead of the spacebar/arrow keys. My guess is that it might be possible to write a Java or Kotlin wrapper that handles the mobile device's input, and then translates it to a keyboard or arrow key somehow. I don't actually know though. Does anyone have any advice? Thank you EDIT: By mobile devices I mean Android of course :D [link] [comments] | ||

| Is the default actionbar obsolete? Posted: 04 Oct 2020 10:19 AM PDT Are there any advantages of using the default actionbar instead of going with a custom actionbar which offers much more flexibility? [link] [comments] | ||
| Framework to build map related application (about trails, POI and so on...) Posted: 04 Oct 2020 12:10 PM PDT Hi! I want to develop a map app about trails, POI and other map related stuff. It's tempting to use Flutter or React Native, but I'm worried about flexibility of the frameworks. What would you choose? [link] [comments] |
