DrawView | Android view that allows the user to create drawings | Editor library

I am making a 2d endless runner in which I have implemented some code for gravity and movement of player. When I added gravity and velocity to player via a script attached below and enabled the play mode a scene named "DontDestroyOnLoad" appears in the hierarchy window and it has an object named [Debug Updater] as a child attached to it. The script for player is here:

I'm just trying to add a shadow to the image, which is not just rectangular, I'd like to apply the same mask effect as image has. On stack overflow I've found the same question, but the answer is suggested on objective-c language - iOS SDK - drop shadow on masked image Can you please help me wit swift-code on this question. Thanks in advance.

I am trying to create multiple rectangles based on user inputs i.e. col,row.

My requirements are

1. I need to pass the two input values(num1,num2) from MainActivity.java between onclick to CanvasActivity.java(col,row).

2.In my code I am able to draw rectangles on creating the app but I need to draw rectangles after the button press. ---- this is done

MainActivity.java

I have a class named DrawView which extends View and is on top of a TableLayout. I'm using this class to draw 1 simple line using the drawLine() method. My TableLayout is being overdrawn because my DrawView class is on top of it. How can I prevent this? My line needs to be on top of the TableLayout, said line isn't using the whole canvas, so I thought setting the background to transparent would fix it, which isn't the case.

please someone help me "To save an image file with increment at end of file name" like("image 1.jpg , image 2.jpg , etc..")

here is my code

please some help me to make this,i am new learner to android-studio.

When if we pass in a binding variable (like $saveDialog as true) to alert or sheet, the variable will reset to false after that.

The goal is something like this: I start the app, MainActivity starts a drawing thread. This thread draws until some events inside it happens(in my case value i>155) Then this thread stops drawing (but it should not be deleted, and values should not be lost) and starts another activity (a usual xml - file activity) When I want I should be able to get to my drawing thread and resume communicating with it from the place I stooped

To solve the problem I have decided to use a SurfaceView thread and Canvas inside (It would be good to make it a class, not to write it inside MainActivity, because I'm going to insert there a lot of code). I managed to start a thread and to draw something on my screen, but I can't change the activity. The best attempt was to create a handler inside MainActivity and to send there a message from my thread. The thread works OK, but it just freezes and nothing happens when it is time to change the Activity. In the log tab I can see that the thread sends a message, but the MainActivity can't see and handle it.

What should I do? What is the right eay of solving the problem? Please, help a beginner).

MainActivity code:

I want to create a irregular quadrilateral using 4 draggable points in android as given in image below.

desired quadrilateral I want

so that user can manually drag the points one by one and put create quadrilateral as they want using 4 points what I've tried yet is given below.

I am an intermediate to android developing and I were given a module of an app which includes all the operations of the canvas i.e. free drawing, shapes and text. I have done with the free drawing and its undo/redo operations. But i am not able to figure out how to undo redo shapes drawn on the canvas. When i use the methods : canvas.drawRect(args) it goes fine same in the case of circle, arc etc but i am not able to delete those from the canvas. If i use Path.addRect(args) and draw in onDraw() then the shape is not rendered when i am dragging to draw when i take off finger then shape appears. below is my DrawView class : Thanks in advance!
