| Why is Android careless about NDK even AFTER YEARS? Posted: 31 Aug 2016 09:45 AM PDT Hi, I am wondering why Android's NDK (current ndk-12) has just a fraction of the features compared to its Java pendant? There is no way around C/C++ for real-time virtual reality applications. However, due to the limitations of NDK it is de-facto impossible to make such apps. Example: For now, you cannot have native camera access. This forces you to switch to Java. You will drop some FPS by doing so. In Java the best-case frame rate is 30 FPS (just fetching frames, no actual image processing). In my view this is ridiculous. With an IPhone you can grind left handedly 60 FPS and go all C/C++. Here is a thread someone pointing it out BACK IN 2009! https://groups.google.com/forum/#!searchin/android-ndk/camera%7Csort:relevance/android-ndk/qehnrEEoxa0/FAnRodBr0FYJ [link] [comments]  |

| I want to do Android development, but can't come up with any app ideas Posted: 31 Aug 2016 11:48 AM PDT Android development is something I've wanted to get into for a long time, as early as the 1.x days. I dabbled around the 2.x era and got close to releasing a game I was working on, then got busy with school and never released it. Now I'm picking it back up, but I feel like so many of the potential good app ideas have been done by now. Currently, I'm focusing more on making things for the sake of making things. I spent the past weekend writing a crappy Instant Messaging program using Firebase as a backend to learn about Firebase. I spent Monday evening refactoring it to make use of MVP rather than One-Big-Activity. Yesterday I further refactored it to make use of Dagger and ButterKnife. I plan to continue working on this app as a method of learning new libraries and design patterns. Next on the list I think is to adapt parts of it to make use of RxJava. Once that project is "done" I'll probably keep churning through the classics. Like a To-do list app, everyone seems to need to write one of those :) Practice is all well and good, but I want to eventually get to the point where I'm planning on creating something to actually release. So, I'm curious, where do you draw your inspiration from? [link] [comments]  |
| A Kotlin library allowing writing asynchronous code in synchronous style Posted: 31 Aug 2016 03:53 AM PDT Thanks for coroutines introduced in Kotlin 1.1, we built a tiny Async/Await library allowing writing asynchronous code by very straightforward manner, like You may have many await calls inside async block, have it in loop etc. Disclaimer: Kotlin 1.1 is not released yet, you have to use latest EAP in order to use the library. See detailed instructions on the library's homepage. [link] [comments]  |
| What is the best approach for custom loading & success animations? Posted: 31 Aug 2016 06:17 AM PDT I've been looking into animations for Android there I am unsure about the best way to create them. What I'd like: a spinning circle (with some pieces missing) that becomes an entire circle then a checkmark forms inside of it. What is the best way to handle it? Approaches I've noticed
Any help or resources would be appreciated. [link] [comments]  |

| Posted: 31 Aug 2016 03:29 PM PDT I've looked at Open Weather and it doesn't look like it has chance of rain percentage for the next day. Anyone know of any (preferably free) other ones? [link] [comments]  |

| Microphone PCM to Playable AAC for RTMP Stream Posted: 31 Aug 2016 11:24 AM PDT Hey guys, I'm having some problems with encoding. How can i encode pcm to aac for rtmp stream. Any ideaa ? [link] [comments]  |
| Error Code -2 from Google Play Store Posted: 31 Aug 2016 11:01 AM PDT I have researched in depth into this issue, and could use a bit of insight. For whatever reason users are trying to download our application from the Google Play Store and receive an error code -2. From everything I have read online, it seems as though a republish would fix the issue. Figured it wouldn't hurt to reach out and see if anyone else has similarly faced this issue, and what steps you took to fix. Thanks [link] [comments]  |

| Posted: 31 Aug 2016 01:50 PM PDT To try and learn how to create my first app I'm basically trying to re-create OfferUp an app which is like Craigslist but functions on local posts filtered by location. I understand how to get a users location from androids location updates, and how to create a table with attributes in DyanmoDb with user posts. I don't get how to query the posts based off location. I'm assuming I can store the Sellers location in Latitude/Longitude points as an attribute to their post, but I'm not sure how to filter out search results based on location from that. So basically I understand how to ask for and store a Users location but I don't understand how to query based on that. Hoping someone could point me in the right direction. [link] [comments]  |

| Tendencies on modern Android development Posted: 31 Aug 2016 03:23 AM PDT I worked in Android back in late 2012 - early 2013 and then a little more in 2014. Now I am back fully in Android dev (spent the last three years on big web application development with Spring, Hibernate, etc.) and I feel kind of lost. The API has not changed that much I admit but I've spent some time reading stuff online and I don't know what's the tendency anymore. There is so much information online, and such a big part of that is outdated, it is hard to know how to start an app from scratch with the best, current practices. Back in the day Fragments where the thing and now I've read people absolutely dismissing them for overcomplicating the code. I've seen libraries like Dagger, Mortar & Flow, using retrofit for REST and Picasso for images (it was UIL back then!), people advocating for Reactive, etc. I also know there is no single bullet but I need to know about the stuff before I can decide it is useful for me or not. Any good website where I can check all these things and what they are good for? I know I can search every one of these terms but maybe there are some other good things that I'm missing.
