Due to limitations that prevent deep links like Intent URIs, developers encounter difficulties when attempting to open apps from the Instagram webview on Android. Fallback techniques like QR codes, server-side redirects, and improved Universal Links are examples of solutions. Webview constraints can be successfully circumvented by combining creative approaches with extensive testing.

Limitations in Instagram's WebView, which can prevent functionality like autoplay or inline playback, are frequently the cause of videos not displaying in the browser. Optimizing HTML video characteristics, confirming the existence of the file on the backend, and testing in different contexts are necessary to address this. A seamless viewing experience is guaranteed by these adjustments.

Many developers face issues rendering a Leaflet heatmap in an Android WebView, especially when encountering the "getImageData" error. The canvas element's zero height in Chromium-based browsers is the cause of this issue. It's interesting to note that GeckoView handles the same heatmap with ease. Developers can utilize WebView-specific solutions or change the canvas dimensions to fix issue.

When handling'mailto' links within Android applications, integrating WebView frequently results in problems with user experience, including failures when trying to launch email clients directly from the web content.
