| Posted: 20 May 2016 03:10 AM PDT did anybody notice that you can actually reverse (decompile) any APK using the new APK Analyzer that is embedded into Android Studio 2.2 P1? literally you could see any app details ( human readable language) XML, java code and anything else that could be reversed.

| Interpreting Google "prompting for rating" rule? Posted: 20 May 2016 08:05 PM PDT So, the official policy states that the following is a common violation:
However, the image displayed is to do with rewarding users for a high rating, not for rating in general. Does anyone know if offering x gold / xp / whatever in return for clicking the "rate app" button is permitted? [link] [comments]  |
| How to listen to the database without constantly querying it? Posted: 20 May 2016 05:26 PM PDT Alright so I have a local chat function built, but it does not work in real time. It seems like a waste to query the database every few seconds, isn't this very expensive and inefficient? I used Sinch sdk for my private message function, and it works well for 1-1 messages, but a message may not be sent to more than 10 people. I used Ractive.js in my website to accomplish tasks like these, does Android Studio have any front-end real time services I could use? Someone mentioned Cloud9 or WebRTC; I am not familiar with them but they seem like Back-end shit. I already have my backend working. [link] [comments]  |
| Firebase and google play services have a lot of duplicated functionality Posted: 20 May 2016 08:18 AM PDT Here are the firebase and play services components. Seems like both have a lot of components in common, should we favor the firebase ones ? [link] [comments]  |

| How bad practice is it to store all data in a JSON Array? Alt title: Alternatives to SQLite? Posted: 20 May 2016 06:47 PM PDT Hey everyone, I'm more or less working on a simple TODO list with some extra fields in my spare time right now. Long story short, I never took the time to learn SQLite. I have a basic app with the database portion half working, and hacked together, and have learned to hate SQLite on Android, more or less because I haven't put in the time to learn how it actually works. Serializing all of my data, pushing it to a JSON Array, and shoving it in shared prefs would take all off 30 minutes for me to do. If the user hits the clear all button, I can nuke the whole thing, and if they add to it, I can write back to the array. But how bad is it to do this? JSON isn't the most compact format. And I would be writing the whole thing each time the user added a single field. I don't think this would be an issue for my tiny app, but I don't know if it would scale well, or if it is even a good idea in the first place. Should I get over myself, and put in the time to learn SQLite, or is there some alternative that won't make me feel like I'm forcing a second programming language into my Java? [link] [comments]  |
| Posted: 20 May 2016 05:04 PM PDT I'm needing a situation where the phone screen shows a cursor even if the finer is not touching but only hovering near the screen surface. I actually need this for a windowsphone, but i thought it would be better to begin where the more advanced developer tools reside... (then i can learn some keywords to look around in the windowsphone area, or change to an android phone) [link] [comments]  |
| Posted: 20 May 2016 05:09 AM PDT There are some nice features in the job scheduler, such as being able to define what conditions are required for your job to be processed. Wait till charge, wait for wifi, and wait till the device is idle... then and only then upload these new photos to the cloud. But the nice thing about cloud sync is that your data is always available everywhere. Google is asking developers to sacrifice instantaneous sync with an option that'll be better for the battery + memory by making us use the job scheduler. Will anyone really use it "correctly" though? Spotty file sync is a big price to pay for battery optimizations. And the apps reputation pays for the battery savings. The big problem is that the user can't "see" an app wasting their battery in the background - they don't actively notice that. But they'll certainly notice spotty cloud sync, where photos and other files don't "instantly" appear across their devices. They'll blame this on the app. All because you, the developer, chose to wait for wifi, charge and phone idle state before upload your users photos to the cloud. The natural reaction to this, then, is to just tell the job scheduler to run your job ASAP. It would be nice if we all decided to make proper use of the job scheduler, (and I'm sure core apps from Google will) but it is just going to be a "race to the bottom" for the rest of us and most developers are going to just force to job scheduler to run their job ASAP. If a competitors app has seamless file sync (because they do it frequently, wasting a little more battery then usual), and yours just feels spotty (because you are performing optimizations invisible to the user and holding off your sync until the 'right time'), then users will just go with the competitor. Also imagine if the user had no access to wifi. Or if they lost their phone at the Google Keynote without plugging in, so now all their cool i/o photos (that would normally be synced to their Dropbox) are lost along with their phone. Yikes. 😁 [link] [comments]  |
| Having a very hard time learning how to setup a web API and server for my Android app. Suggestions? Posted: 20 May 2016 12:58 PM PDT Since I already know Java, I preferably want to use Jersey or JAX-RS. Some RESTful service. I've read tons of tutorials on everything ranging from Django to Flask to JAX-RS and now even books like O'Reilly's Java Web Services and I'm finding it all very difficult to follow. Everything I'm finding either assumes I have a lot of previous knowledge on web api's, or are far too short and barely actually teach anything. Far too often I run into a short 'guide' that at some point tells me I want to create a "view," or whatever else, like I obviously know what that even means. Or one of Spring's guides for their framework that barely teaches you anything or explains anything and leaves you hanging to learn more. I was going through the Android framework so fast just a few days ago and since learning that I need to create a web api, feel I've hit a brick wall in developing my app. And I'm probably making this a lot tougher than it really is, but I can't find anything that walks through setting up a server online, creating a database, handling requests, and user login/authentication. FWIW I know how to work with a MySQL database using the JDBC so I'm not completely unfamiliar with databases and SQL. Honestly rather avoid Parse because I do want to learn how to setup a web api and I know this would be important for the future, but I feel like I'm beating myself up at this point and not making any progress. So how did you guys learn how to create web api's? Any suggested resources online? Thank you. [link] [comments]  |
| Infer annotations in Android Studio Posted: 20 May 2016 07:55 AM PDT So I was watching the "What's new in Android development tools" Google I/O talk, and they mention this feature called "infer annotations". You can see it here: https://youtu.be/csaXml4xtN8?list=PLWz5rJ2EKKc8jQTUYvIfqA9lMvSGQWtte&t=1260 I couldn't find this feature in 2.2, he mentions it's behind a flag, but there's no information about how to activate it, does anyone know how to do it?

| Posted: 20 May 2016 08:47 AM PDT Common compile-time code optimizations. Like putting constant expressions outside a loop, getting rid of dead code, stuff like that. Right now I have to keep checking to see if I should sacrifice readability for what seems like a performance boost, but what's the point if the JVM automatically does that optimization?

| [Discussion] Play Services / Firebase Task API Posted: 20 May 2016 09:34 AM PDT What do you guys think about it? I wish they'd embraced RxJava instead. It's nice that you can scope a callback to an activity, but apart from that it feels both too rigid and too weak. Especially when you comepare it to Rx. I want to wrap a task in an observable but "unsubscribing" or canceling a task is not trivial. According to this talk at IO, we're about to see a lot more of it. [link] [comments]  |

| Can someone do a little piece on setting up a RAM disk to speed up android development? Posted: 20 May 2016 12:08 AM PDT How to set it up to begin with. Like, all temp directories could be put in RAM, but which ones? And how to set up the process of something like "Click once to setup the RAM disk automatically before starting Android Studio", so we can just setup the RAM disk once per session and just forget about it. And how to make sure we won't lose any data? [link] [comments]  |

| Newbie in Android development looking for help Posted: 20 May 2016 07:05 AM PDT Hello, I'm currently student in Master in computer science in France and I am in Internship for my formation. I found an internship in a society working for new technologies (connected glasses allowing technicians to be in real time communication with expert a bit like teamviewer...). I haven't really got much training from the company who hired me as intern and I don't really have anyone to ask programming questions to. So far I got told that my mission would be to "develop an app that allows people to detect POIs like Layar for mobiles" So me and another intern working on this project guessed that the simpliest way to do something satisfying would be to use the Layar SDK to develop the app (since we guess our superior wants to have virtual reality included to detect nearby POIs via camera) My problem is that my Android experience is very basic (made a game applications with Android for a class so I know a bit of the basic and have used Android studio) and I had never really used any GPS/map using app, so I checked few video tutorials but many of the things that were used in those seems to be decrepated & API 23 permissions makes it really annoying to test app on my AVD. What I am looking for is somewhere (or someone) to ask questions to that could be extremely basic and that could answer a few of them regularly (not always), Stackoverflow etc seems to be more of a site where you'd ask one question on a very particular matter and less questions about "what is the best way to implement a solution for this problem" or less "newbie/stupid" questions, if anyone has an idea what I could do, I'm a bit lost and as I said I don't reallu have someone to ask questions to in my internship.
