CUtils | an android tool library | Android library

I am trying to design an MPC controller in Python but I really don't know where to start. I watched videos on YouTube but I was confused even more. Basically, this is for a simulated autonomous vehicle. I've finished the PID controller for it but I didn't run it on the simulator yet:

I'm writing a discord bot and recently decided to move all of the commands into "Cogs". All of the python files within my cog folder import other modules I've written that have helper functions and whatnot in them (I store them in a named cutils). They seem to import fine, but when I try to run the bot, I am getting the following traceback:

I am getting the following error:

java.lang.IllegalArgumentException: No available camera can be found.

when calling and instance method ProcessCameraProvider.bindToLifecycle(). See this in the context of the code below by searching for "------ Code Crashes Here --------------".

How do I prevent this error and subsequent crashing of the app? More specifically, how do I ensure the CameraSelector can return a camera instance for the Nexus 6?

It appears there is something wrong with the CameraSelector used in this call. If I set a breakpoint on the bindToLifecycle line, and debug up to that point and add a watch for `cameraProvider.hasCamera(cameraSelector) it returns false. Maybe this is not intended to return true until the bindToLifecycle method has been called. If so, how can I verify the cameraSelector object has been created sucessfully (successfully meaning it points to an actual camera object)?

In the creation of the cameraSelector object, I use the requireLensFacing method in the builder, so it appears the Nexus 6 hardware does not tag anything with these LENS_FACING_BACK or LENS_FACING_FRONT and therefore does not return any camera instance? Do I understand this correctly?

I should note that this error did not occur when the exact same code was run on a Nexus 5, which is why I am inclined to think it is a hardware issue.

I also tried the LENS_FACING_FRONT int, but had the same error. If I remove the requireLensFacing build component altogether I get a different error:

java.util.NoSuchElementException

I'm learning about hooking and decided to try hook the Win32 API function LoadLibraryA to see if something is injecting a DLL through CreateRemoteThread and LoadLibrary. I'm hooking from my own console application I want to protect.

I was able to detect that something inside the process space of my application is calling LoadLibrary, but how do I find more information about what was loaded? Could I get the DLL path and name for example?

Defining the prototype of LoadLibrary:

I am currently in the process of writing an application that will capture a lot of RTSP streams(in my case its 12) and display it on the QT widget. The problem arouses when I am going beyond around 6-7 streams, the CPU usage spikes and there is visible stutter.

The reason why I think that it is not QT draw function is because I have done some checking to measure how much time it takes to draw an incoming image from camera and just sample images I had, it is always a lot less than 33 milliseconds(even if there are 12 widgets being updated).

I also just ran opencv capture method without drawing and got pretty much the same CPU consumption as if I was drawing the frames (lost like 10% CPU at most and GPU usage went to zero).

IMPORTANT: I am using RTSP stream which is a h264 stream.

IF IT MATTERS MY SPECS:

Intel Core i7-6700 @ 3.40GHZ(8 CPUS) Memory: 16gb GPU: Intel HD Graphics 530

(Also I ran my code on a computer with dedicated Graphics card, it did eliminate some stutter but CPU usage is still pretty high)

I am currently using OPENCV 4.1.0 with GSTREAMER enabled and built, I also have the OPENCV-WORLD version, there is no difference in performance.

I have created a special class called Camera that holds its frame size constraints and various control functions as well stream function. The stream function is being ran on a separate thread, whenever stream() function is done with current frame it sends ready Mat via onNewFrame event I created which converts to QPixmap and updates widget's lastImage variable. This way I can update image in a more thread safe way.

I have tried to manipulate those VideoCapture.set() values, but it didn't really help.

This is my stream function (Ignore the bool return, it doesn't do anything it is a remnant from couple of minutes ago when I was trying to use std::async):

I need to debug several VBS files that make up a HTA application.

I've searched the web and couldn't find the exact QA. This one about How to run multiple batch files with single External Tool in Visual Studio and How to debug IE9 HTA? which a silver bullet hasn't been found.

This is where I'm stuck, I debug main.vbs and it references a class cutils which is in the file utils.vbs. And when I step over this line to instantiate cutils I get an error:

Microsoft VBScript runtime error: Variable is undefined: 'cutil'

So I tried a few External Tool Arguments like comma separated files:

when i click on register button i get "unfornately project has stopped working" if you tell me to add more code regarding this then add more but plzz help me main activity

I have an issue with lower api I tasted my app on 15, 19 and 22 api the crashes on start the only ones works are 24 and above api I don't know why my app is just Math calculations .I searched a lot to find answer for last 2 days and I tried myriad of thing none of them work for me. Here is my full logcat error and code.Thanks for any help.

I'm working in React Native Application. I'm trying hard in Android to make use of Notification Services & BIND_NOTIFICATION_LISTENER_SERVICE. I'm trying to read the incoming notifications using NotificationListenerService.

I'm using One Plus 5T (Android Oreo) for debugging.

I've seen lots of duplicate questions and I've tried the following solutions which I got from those questions.

1.Restarting the phone (Sounds silly and it doesn't work)

2.Re-install/Re-build the application

1. Renaming the NotificationListenerService class file and run Etc..

Problems I've been facing,

1.Cannot see my application in 'Notification Access' settings.

2.onCreate / onNotificationPosted is not getting called when I receive any Notification

3.Checked whether my application is having Notification permisson or not using the below code and it returned 'false' (Obviously, that's my problem)
