In writing an image processing app for my internship using opencv and I noticed that a few of the image transformations take a while. I've optimized things the best I can but it still takes a few minutes to run.
I recently came across information about renderscript but im hearing that it isn't as effective as people would like. Some are even going as far as saying that renderscript can even make your program run slower, even if you're working with data parallel constructs.
What do you guys think?

As my Master's degree work, I have chosen to work on some kind of biometry system (mobile application) that will track biometry characterisitcs of owner (like pressure on display, area of press, gyroscope angle, gestures) during using of phone, and build model of user based on tracked characteristics.
Basicaly said, my app will track your work with phone, and build your model. When model becomes accurate, app will be able to tell if actual user of phone is its owner or not.
My question is - how can I track data from sensors (gyroscope, area of press, dynamics of writing, gestures, touch-related and so on) during whole usage of phone ? Is it possible with/without the root? I thought about layer that will work on principle like Messenger chatheads, but I don't think tracking touch will be possible this way for obvious reasons (it would be easy to track users input to display and keyboard input). My last chance is implementing my own service to track services into Android source code, but that would be overkill.
Thanks for any advices how to accomplish task of tracking sensors/touchscreen on Android.

Currently my app is communicating with the database through PHP, and although i don't have any problem with PHP, is there any other way to handle the communication?
If i have to name a problem with PHP, it might be the fact that i have to run an HTTP server (xampp) and migrate my MySQL db under xampp be annoying sometimes.
Anyone has some experience ASP.Net's Web API as a PHP replacement?

Working on a new app, I'd like to add some hidden options only reserved for specific users. This would be useful to add some debug options, make a free version with unlocked features and no ads for my beta-testers etc... without having them going through the installation of an APK by hand.
My idea was to simply add a big old if statement that checks if the user is in the whitelist I would create, and if it is, add some options/disable ads etc... However the only way I can think of doing that is by grabbing the username/email of the google account. It's easy to do, but I need some special permissions (either android.permission.GET_ACCOUNTS or android.permission.READ_PROFILE depending on the implementation).
The thing is, I don't need those permissions anywhere else on my app, and I'm reluctant to add permissions for everyone just to isolate a few specific users.
So is there anyway to do this without any special permission? Anyway to identify a specific user/smartphone that I could check in my code?
If not, is there any other way to give special versions of my app to specific users, apart from giving them the APK directly?

Java is it's industry standard, but a lot of people don't seem to to favor that language. C# is commonly talked about as a good alternative, along with languages that work in the JVM such as Kotlin. How would you rank them for ease of android development, and for what you would actually recommend? Is Java "by far" the best one for it? Is the second best language for android development a "distant" second. Go was developed by Google engineers. Have they made Android development pretty painless yet?

Hi, I'm thinking of making an app that realistically simulates a flying airplane in a 2D world. I know there are a few good 2D physics engines out there, but I'll also need to model the flight dynamics of the plane. I've looked around on the web and found some pretty good Flight dynamics modelling tools like JSBSim, but they seem way overkill and even then I'll have to project its output data into 2 dimensions.
I'm aware that with a bit of effort, I can make my own -good enough- flight dynamics model. But I'm just checking to see if it's been done before so I don't needlessly reinvent the wheel.
