Weekly "anything goes" thread! Posted: 01 Feb 2019 04:41 AM PST Here's your chance to talk about whatever! Although if you're thinking about getting feedback on an app, you should wait until tomorrow's App Feedback thread. Remember that while you can talk about any topic, being a jerk is still not allowed. submitted by /u/AutoModerator [link] [comments]

Material Components 1.1.0-alpha03 release Posted: 01 Feb 2019 11:13 AM PST submitted by /u/GGDev [link] [comments]

I built a new material theme music player that works all form factors (phones, wear, auto, cast, assistant) and uses latest tools (Kotlin, Architecture components, Room, Databinding) Posted: 01 Feb 2019 01:04 PM PST Hey Reddit, Around 6 months back, I decided to completely rewrite my Timber music player and today I have published the new version, TimberX. https://github.com/naman14/TimberX ​ TimberX is built with latest development tools and design patterns. Written in Kotlin Android Architecture Components (ViewModels, Livedata, Room) Databinding TimberX works across all devices including Phones Android Wear Android Auto Chromecast and other cast devices Google Assistant I know that there are lots of music players out there but I always wanted to rewrite my original music player in Kotlin and properly explore the capabilities of the MediaSession APIs in Android. This new version is built on a single MediaBrowserService that is used by all connecting clients. Looking forward to the feedback on the architecture of the app and contributions are welcome. Thanks! submitted by /u/naman14 [link] [comments]

Why Android does not received material slider component? Posted: 01 Feb 2019 01:34 PM PST Why flutter and even iOS have all newest material components and Android does not? Flutter is a kinda new while Android has been around and still receives no components. Right now I need smooth discrete slider and no library does provide it. I refer to this slider: https://material.io/design/components/sliders.html Should I spend two months trying to create it? :D submitted by /u/wellbranding [link] [comments]

In general, why does android development needs to be so hard? Posted: 01 Feb 2019 01:41 AM PST So, I did did few mobile games for client in hybrid environment with some html framework that works on canvas lately. Before this I have year and a half android dev exp with around 10 apps built. In this hybrid environment I'm able to produce same result as within android, with 3 times less code (minimum) and quite faster. So, why exactly is android development so complicated? Is it cause it has flaws at the very start? Is it cause it has to adapt to 1000 of different type of phones/companies, is it cause of Google? submitted by /u/KisniDan [link] [comments]

Tips to promote my first app? Posted: 01 Feb 2019 02:22 PM PST I've created a fully working, decent app (not going to state the nature of what it is for anonymity, but it's a tool). Similar apps on the Play Store have gotten in the range of thousands to tens of thousands of downloads. My app has ads on it so I wouldn't mind getting a bit of revenue, even if it's much less than a buck a day or something. ​ My app is just as good, if not superior to the similar ones with tens of thousands of downloads. The issue is that there's no way for people to see my app, as it's only recently been published, and doesn't show up among the top search results, or even after scrolling down for a bit. The only way to get my app very mild popularity is for me to promote it somehow. ​ I don't plan on it becoming super popular or anything like that; the app is a tool with obscure use cases, so I'm not going to cash out on fake downloads or anything like that. I'm wondering if there's any online community where people are willing to check out each other's apps and give honest reviews, or if there are sites where you create a post for your app, etc? submitted by /u/AskingUniQuestions [link] [comments]

Upgraded Android Studio to 3.3 and clicking on string resource id's now take my to R file instead of the string? Posted: 01 Feb 2019 10:20 AM PST Is this happening to anyone else? Is there a fix? I've tried rebooting and invalidating caches... It's a giant pain in the ass. submitted by /u/AmIHigh [link] [comments]

Admob Matched Requests getting blocked at around 5000 Posted: 01 Feb 2019 10:29 AM PST We have an app with approximately 50K daily active users. On one screen we are showing an interstitial ad. Everything worked fine until 5000 match requests. After the 5000 matched request was already served, Admob stopped serving ads to any ad units throughout the app. Have any of you had similar issues with admob? I'm attaching a screenshot of the admob report: https://i.redd.it/rladohvq20e21.png submitted by /u/sagarrishabh [link] [comments]

Tutorial: android state v. event Posted: 01 Feb 2019 02:58 AM PST Put another tutorial and sample app on dev-to this week, goes into the difference between state and events when it comes to driving android UIs (or any UI actually) - it's something that comes up a lot no matter which MV* architecture you develop with https://dev.to/erdo/tutorial-android-state-v-event-3n31 in case anyone finds it useful submitted by /u/erdo9000 [link] [comments]

Seeking advice for a first time app project Posted: 01 Feb 2019 09:21 AM PST My company is a small consumer products company that sells a variety of physical products. We have a long range strategy to introduce smart technology into a collection of them. As part of that we would like to develop a basic "brand" app that allows users to connect to a range of bluetooth enabled products to control on/off and various settings of the products. As a physical product development company, delving into the mobile app world is quite the daunting task. I have a few questions if you don't mind: ​ 1) What are common pit falls or issues in a typical app development cycle that a first time should be aware of? 2) We've discussed with about 20 India based development companies and narrowed down to 1. What is the best method to vet their ability to successfully develop the project? 3) What complexities arise when introducing a connected hardware element to a mobile app? 4) What is the typical ongoing maintenance cost as a percentage of the initial development cost? 5) Being very cost conscience our initial plan is pointing toward React Native for cross platform capability. Is this a good idea? ​ As a non-technical person, I appreciate any and all advice on the topic! submitted by /u/6765443 [link] [comments]

Best sub for android development help? Posted: 01 Feb 2019 12:24 PM PST I'm working on my first app and I'm brand new at programming. I'm researching hard and going through a lot of youtube on the basics but I'm getting to the point that finding a sub for programming advice would be best for me. submitted by /u/JaysonTatertots [link] [comments]

Get Firebase JobDispatcher job result Posted: 01 Feb 2019 11:50 AM PST I am currently integrating Firebase JobDispatcher to do some synchronization tasks in background. And I didnt find a way to listen to an event when the JobServices that was scheduled finishes its work. Is there any way to do that? I will integrate WorkManager in the future when Google releases stable 1.0.0. But for now I want to try out Firebase JobDispatcher because it has a similar interface and will be easy to migrate from. I know there are another ways to do this kind of things but I want to know if it is possible to achieve what I have asked. submitted by /u/peterstark4 [link] [comments]

How to keep the same FPS when recording? Posted: 01 Feb 2019 11:24 AM PST Hey guys you could say I'm a newbie in all of this. Lately I've been recording vids with my galaxy phone but when exported on my computer they all have different FPS. I noticed some are at 30 and those look good but some are at 15 and 17 frames per second. I'm not necessarily doing anything different , I'm in the same location. The ones with the lower FPS I noticed my audio was a little bit delayed and my lips didn't match completely with what I was saying like the higher FPS. I don't get it. I'm using the SAME exact camera every time, what am I missing? Is there a way to keep the same FPS around 30 or what determines when one recording is lower than the others with the same camera ? Thanks submitted by /u/BObsessed13 [link] [comments]

Pressing a button to switch fragments is slow and has stuttering ripple effect Posted: 01 Feb 2019 11:17 AM PST I've been having this weird issue that I haven't encountered before. I tried several things to try to isolate the problem but I can't figure out the root of the problem. For testing I have made a new fragment which is basically an empty class with only onCreateView. I attached this fragment to a layout with only one element, LinearLayout. Now whenever I press a button to switch to this new, or every other fragment. It has a delay of like a second or more and the ripple effect on it is choppy/laggy. The weird part is that when do this on an emulator it goes perfectly smoothly, but on the two devices I have with me they are acting up. ​ code: https://pastebin.com/D6xZw4H8 submitted by /u/-Lawliet [link] [comments]

fatal error: 'jni.h' file not found Posted: 01 Feb 2019 09:32 AM PST I am trying to build this share library for I can use my methods in Java. I am sorry if this is the wrong forum, but since this is basically a prerequisite for NDK work, this is the best place that I could think of to ask. ​ I am using this command to build the file using gcc... according to this tutorial: http://www.ntu.edu.sg/home/ehchua/programming/java/JavaNativeInterface.html ​ gcc -I/⁨Library⁩/Java⁩/JavaVirtualMachines⁩/jdk-11.0.2.jdk⁩/Contents⁩/Home/include -I/⁨Library⁩/Java⁩/JavaVirtualMachines⁩/jdk-11.0.2.jdk⁩/Contents⁩/Home/include/darwin -dynamiclib -o libhello.dylib HelloJNI.c ​ It tells me that fatal error: 'jni.h' file not found but that is exactly where the jni.h file is located! ​ Can anyone help me with this so I can get going with my NDK project? ​ Thanks, Lester ​ submitted by /u/Lest4r [link] [comments]
