AnkiDroid Card Images Not Adjusting: A New Study Screen Bug
The New Study Screen: A Mixed Bag for Image Display
AnkiDroid is a powerhouse for spaced repetition learning, helping millions worldwide memorize information efficiently. Its flexibility is one of its greatest strengths, allowing users to create custom study decks tailored to their needs. However, with new features come new challenges, and a recent update has introduced a visual glitch that’s causing some frustration. Specifically, images within AnkiDroid cards are not adjusting to the screen size on the new study screen. This means that if you have a card with a large image, it might be cut off or displayed in a way that makes it difficult to view properly, hindering the learning process. This issue is particularly noticeable when comparing the behavior to the older study screen, where images seemingly scaled more gracefully. The problem doesn't appear to be a global Anki issue, as users have confirmed that the latest version of Anki Desktop does not exhibit this bug, pointing towards a specific implementation detail within the AnkiDroid application. The debugging information provided by the user highlights AnkiDroid version 2.23.0 with a backend version of 0.1.62-anki25.09.2 on Android 16 (SDK 36), running on a Samsung device. This level of detail is crucial for developers to pinpoint the exact cause of the problem.
Understanding the Problem: Image Scaling in AnkiDroid
To truly appreciate the impact of this bug, let's delve a bit deeper into how images are supposed to be displayed on flashcards and why this new screen might be causing trouble. In Anki, cards are essentially web pages rendered within the application. This means that HTML and CSS are used to dictate how the content, including images, looks on the screen. When you add an image to a card, Anki generates HTML for it, and this HTML is then styled using CSS. The goal is for the image to be responsive, meaning it should adapt its size to fit the available space without distorting or becoming unusable. On the old study screen, this responsiveness was likely handled effectively, perhaps through a CSS class or style that instructed the image to scale proportionally. The new study screen, however, seems to be interpreting these instructions differently, or perhaps the underlying structure has changed in a way that interferes with the existing styling. This could be due to a change in how the rendering engine handles image elements, a new default CSS rule that's overriding previous styles, or even a bug in the way the new screen's layout is applied. The expected behavior is that any image added to a card should scale down to fit within the card's display area, maintaining its aspect ratio and ensuring that the user can see the entire image clearly. If the image is smaller than the available space, it should display at its natural size. The current behavior, where images are not adjusting, leads to a degraded user experience, especially for visual learners who rely on detailed images for comprehension. Imagine trying to study anatomy with an image of a complex muscle structure that's cropped off – it's incredibly frustrating and defeats the purpose of the flashcard.
Reproducing the Bug: A Step-by-Step Look
Reproducing a bug is a critical step in the software development process, as it allows developers to reliably test fixes and confirm that the issue is resolved. In this case, the steps are quite straightforward and revolve around the core functionality of AnkiDroid: visualizing a card with an image in the new study screen. The user's report clearly outlines the process, and it's something any AnkiDroid user can replicate. First, you need to ensure you are using a recent version of AnkiDroid, specifically version 2.23.0 or a similar iteration that includes the new study screen. Next, you'll need a flashcard that contains an image. This image could be anything – a photograph, a diagram, a piece of art, or even a screenshot. The key is that the image, when displayed, is larger than what would comfortably fit on the screen without scaling. Once you have such a card, you simply navigate to it within the AnkiDroid app, making sure you are using the new study interface. As soon as the card is presented, the problem becomes apparent. Instead of the image shrinking to fit the available screen real estate, it remains at its original size, often resulting in parts of the image being cut off or extending beyond the visible boundaries of the card. This is in stark contrast to the old study screen, where the same card would likely display the image scaled down appropriately, allowing the user to see the entire visual content. The provided screenshots in the bug report vividly illustrate this issue, showing how the image overflows the card boundaries on the new interface. The difference in behavior between the old and new study screens is the smoking gun here, confirming that the bug is tied to the introduction or modification of the new study interface. This specific behavior, where images fail to scale down, is the core of the problem that developers need to address to restore the intended visual experience for AnkiDroid users.
Expected vs. Actual Behavior: What Should Happen?
The core of any bug report lies in clearly defining the discrepancy between what the user expects and what is actually happening. In the case of AnkiDroid's image scaling issue on the new study screen, the difference is quite pronounced. The expected behavior is simple and intuitive: images should adjust to screen size. This means that regardless of the original dimensions of an image you've added to a flashcard, it should automatically resize itself to fit within the boundaries of the AnkiDroid card display. This scaling should be proportional, meaning the image doesn't get stretched or squashed, maintaining its original aspect ratio. The goal is to ensure that the entire image is visible and legible. This behavior was present in the previous versions of AnkiDroid's study screen, contributing to a seamless learning experience. Users could rely on their images being presented clearly, whether they were small details in a diagram or large panoramic photos. On the other hand, the actual behavior observed with the new study screen is problematic. Instead of adjusting, the images often retain their original size, leading to them being cropped or overflowing the card's display area. This makes it impossible to see the full image, rendering it useless for study purposes in many cases. For instance, if a flashcard requires identifying a specific part of a large diagram, and that diagram is cut off, the user cannot possibly answer the question correctly. This deviation from the expected, functional behavior significantly degrades the user experience and undermines the effectiveness of visual learning within the app. The contrast between the smooth, adaptive image display of the old screen and the obstructive, unyielding display on the new screen highlights a regression in functionality that needs immediate attention from the development team.
Debugging AnkiDroid: Unpacking the Technical Details
Understanding the technical underpinnings of a bug can often accelerate its resolution. The provided debug info for the AnkiDroid issue offers a valuable snapshot of the environment in which the problem is occurring. We see that the user is running AnkiDroid version 2.23.0, identified by the specific commit hash 4f768aa0be34e254d65fd4ebe19781b84e8efc37. This version is linked to the Backend Version 0.1.62-anki25.09.2, with a specific Anki desktop version of 25.09 3890e12c9e48c028c3f12aa58cb64bd9f8895e30. This backend version information is crucial as it indicates the underlying Anki core that AnkiDroid is utilizing, and potential discrepancies between the Anki desktop and AnkiDroid implementations could be a source of issues. The device in question is running Android version 16 (SDK 36), a fairly recent version of the Android operating system, on a Samsung device (SM-S906B, model g0sxeea). The Webview User Agent string further details the browser engine used by AnkiDroid to render cards, which is a version of Chrome (142.0.7444.171). The ACRA UUID is a unique identifier for crash reporting, and while not directly related to this visual bug, it signifies that crash reporting is enabled, which is good practice. Importantly, FSRS (Free Spaced Repetition Scheduler) is enabled and set to version 5.1.0. While FSRS primarily affects scheduling algorithms, it's good to note its presence, though it's unlikely to be the direct cause of an image scaling issue. The absence of any specific errors or exceptions in this particular debug log doesn't mean the issue isn't a bug; rather, it points towards a rendering or styling problem within the user interface rather than a catastrophic crash. Developers will likely need to examine the CSS and HTML rendering process for images specifically within the new study screen's layout to identify why the expected scaling behavior isn't being applied. This detailed information helps rule out broad compatibility issues and focuses the investigation on the AnkiDroid UI's image handling logic.
Why This Matters: The Impact on Learning
While a bug where images don't scale might seem like a minor inconvenience, its impact on the AnkiDroid learning experience can be significant, especially for users who rely heavily on visual aids. Anki is a tool for effective learning, and a degraded visual presentation directly hinders that effectiveness. For many subjects, images are not just decorative; they are integral to understanding the material. Consider learning a new language where flashcards might include pictures of objects, or studying history with maps and portraits, or delving into science with complex diagrams. When these images are cut off or unviewable due to improper scaling, the flashcard loses its educational value. A student trying to memorize the parts of a cell might see only half a mitochondrion, or a geography student might be unable to identify a country on a map that's partially hidden. This forces users to either switch back to the older, less feature-rich study screen (if available and functional) or abandon the use of images altogether, which is a compromise many are unwilling to make. Furthermore, the inconsistency between the old and new study screens creates a jarring user experience. Users expect new features to improve their workflow, not introduce regressions. The fact that this bug does not occur on Anki Desktop suggests it's an issue specifically within the AnkiDroid implementation of the new study screen's rendering engine. This means that developers need to carefully review how image elements are being handled in the mobile interface. Restoring proper image scaling is not just about aesthetics; it's about ensuring that AnkiDroid remains a powerful and versatile tool for all types of learners, including those who benefit most from visual information. A smooth, predictable display of card content is fundamental to maintaining user trust and satisfaction with the application.

The bug report itself is a crucial first step, providing the necessary details for developers to begin their investigation. As seen in the provided debug information, users are equipped to supply valuable data, including app versions, device specifics, and even screenshots, which greatly assists in narrowing down potential causes. The confirmation that this issue does not occur on Anki Desktop is a key piece of information, strongly suggesting that the problem lies within the AnkiDroid's specific implementation of the new study screen's rendering or styling. Developers will likely need to examine the CSS and HTML structure used for displaying images within the new interface, comparing it to the older implementation to identify the specific rule or change causing the scaling failure. Potential solutions could involve adjusting CSS properties like max-width, height: auto, or object-fit to ensure images adapt fluidly to their containers.
