HTML Canvas Not Rendering on Older Android Browsers - Unexpected Blank Screen
I'm attempting to set up I recently switched to Does anyone know how to I'm migrating some code and I've spent hours debugging this and Hey everyone, I'm running into an issue that's driving me crazy....... I'm developing a web application that heavily utilizes the HTML5 `<canvas>` element for rendering graphics and animations. However, I've encountered a perplexing scenario: on some older Android devices, particularly those running Android 4.4 and below, the canvas does not render at all, resulting in a blank screen. I've tested this on various devices and the scenario seems consistent across Chrome versions lower than 50. Here's the relevant part of my code: ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Canvas Test</title> </head> <body> <canvas id="myCanvas" width="400" height="400" style="border:1px solid #000000;"></canvas> <script> const canvas = document.getElementById('myCanvas'); const ctx = canvas.getContext('2d'); ctx.fillStyle = 'blue'; ctx.fillRect(10, 10, 150, 100); </script> </body> </html> ``` I’ve confirmed that the canvas is correctly structured in the HTML. When I attempt to debug using Chrome DevTools on these devices, I don't see any JavaScript errors, but the canvas context appears to be `null` when checked. I’ve tried adding a `document.ready` listener to ensure the code runs after the DOM is fully loaded, but this didn't resolve the question. Additionally, I’ve looked into the compatibility of HTML5 features on various browsers but couldn’t find any specific issues related to the `<canvas>` element for these versions of Android. I’m also concerned about performance implications, as the application needs to run smoothly on low-end devices. Are there any known workarounds or specific considerations I should keep in mind for rendering the canvas on older Android browsers? Any advice on how to make it work would be greatly appreciated. For context: I'm using Html on Windows. I'd really appreciate any guidance on this. The project is a service built with Html. Any help would be greatly appreciated! My development environment is CentOS. Any ideas what could be causing this? Any suggestions would be helpful.
