Improve the constraint logic

Oct 13, 2025 by wbrum.org 45 views

Introduction

As a user of the Sony Xperia 1 V, you expect your device to behave in a certain way when it comes to app interactions. However, it seems that the "App in foreground" constraint is not working as expected in the Key Mapper app. This constraint is crucial in disabling actions when a specific app is open, but in this case, it's not working as intended. In this article, we will delve into the issue and explore possible solutions to get the app working as expected.

Describe the Bug

The issue arises when trying to remap the shutter+focus button to control the flashlight and open apps. The user has tried using another app called "Button Mapper" in the past, which allowed for disabling actions whenever a specific app was open. However, with the Key Mapper app, it seems that the opposite is happening. When the app is not in the foreground, the shortcut doesn't work, but when it is in the foreground, it does work, giving the "camera is active" warning in the camera app. This is the opposite of what the user is expecting.

To Reproduce the Behavior

To reproduce the issue, follow these steps:

Add a trigger: Hold down the focus button (shutter button half-way down) for 500 milliseconds to enable the flashlight.
Add constraints: Set the constraint to disable the action if Sony Videography Pro, Photography Pro, Cinema Pro, or Music Pro are in the foreground.
Test the constraints: With the constraints set, the flashlight does not enable, even if the apps are closed. If the constraints are removed, the flashlight enables, even with the apps open.

Expected Behavior

The expected behavior is that if the apps listed above are not opened, the flashlight should enable. If they are opened, the flashlight should not enable, and the shutter button should work as normal.

Device and App Info

Device: Sony Xperia 1 V
Android version: 15
Key Mapper version: 2.8.1

Possible Solutions

Based on the user's description of the issue, it seems that the "App in foreground" constraint is not working as expected. Here are a few possible solutions to get the app working as intended:

Update the Key Mapper app: Make sure that the Key Mapper app is up-to-date, as the latest version may have fixed the issue.
Check the constraints: Double-check that the constraints are set correctly and that the apps listed are not excluded from the constraint.
Try a different trigger: Try using a different trigger, such as a single tap on the focus button, to see if the issue is specific to the long press trigger.
Contact the developer: If none of the above solutions work, it may be worth contacting the developer of the Key Mapper app to report the issue and see if they can provide a fix.

Conclusion

The "App in foreground" constraint seems to be broken in the Key Mapper app, causing the opposite behavior of what is expected. By following the steps to reproduce the issue and trying the possible solutions, we can get the app working as intended. If the issue persists, it may be worth contacting the developer for further assistance.

Future Development

To improve the Key Mapper app, the developer could consider the following:

Improve the constraint logic: The current constraint logic seems to be flawed, causing the opposite behavior of what is expected. Improving the logic to correctly disable actions when a specific app is open would be a great step forward.
Add more trigger options: Providing more trigger options, such as single tap or double tap, would give users more flexibility in customizing their app interactions.
Enhance the app's documentation: Providing clear and concise documentation on how to use the app's features, including the constraints, would help users understand how to get the most out of the app.

Introduction

In our previous article, we explored the issue of the "App in foreground" constraint being broken in the Key Mapper app. This constraint is crucial in disabling actions when a specific app is open, but in this case, it's not working as intended. In this Q&A article, we will answer some of the most frequently asked questions related to this issue.

Q: What is the "App in foreground" constraint?

A: The "App in foreground" constraint is a feature in the Key Mapper app that allows users to disable actions when a specific app is open. This is useful for preventing accidental actions or for customizing app interactions.

Q: Why is the "App in foreground" constraint not working as expected?

A: The exact reason for the issue is not clear, but it's possible that the constraint logic is flawed or that there's a bug in the app. We recommend trying the possible solutions outlined in our previous article to see if they resolve the issue.

Q: How do I update the Key Mapper app?

A: To update the Key Mapper app, follow these steps:

Open the Google Play Store on your device.
Search for "Key Mapper" in the search bar.
Click on the "Key Mapper" app in the search results.
Click on the "Update" button to update the app to the latest version.

Q: What are the possible solutions to resolve the issue?

A: The possible solutions to resolve the issue include:

Update the Key Mapper app: Make sure that the Key Mapper app is up-to-date, as the latest version may have fixed the issue.
Check the constraints: Double-check that the constraints are set correctly and that the apps listed are not excluded from the constraint.
Try a different trigger: Try using a different trigger, such as a single tap on the focus button, to see if the issue is specific to the long press trigger.
Contact the developer: If none of the above solutions work, it may be worth contacting the developer of the Key Mapper app to report the issue and see if they can provide a fix.

Q: How do I contact the developer of the Key Mapper app?

A: To contact the developer of the Key Mapper app, follow these steps:
