Resolving “run-as: Could Not Set Capabilities: Operation Not Permitted” Error on Android

30 November 2024 Stephan Petzl Leave a comment Tech-Help

When working with Android devices, particularly Samsung models, developers may encounter the error message: “run-as: Could not set capabilities: Operation not permitted”. This issue arises when attempting to use the run-as command on Android 6.0.1 and later versions. Below, we provide a comprehensive guide to address this problem effectively.

Understanding the Issue

The run-as command is a valuable tool for developers, allowing them to switch the identity to access app data. However, some manufacturers, like Samsung, have inadvertently disabled this functionality by removing the setuid flag, which is crucial for changing identities. Consequently, the run-as command fails to execute as intended.

Solution Overview

If you are facing this issue on a Samsung device, consider the following alternative approaches to access your app’s data:

• Use ADB Backup: The adb backup command can be a viable alternative to extract the app data. Follow these steps:

  adb backup -f data.ab 
  dd if=data.ab bs=24 skip=1 | openssl zlib -d > data.tar

  Note: Instead of using dd, you may opt for the abe tool, which also facilitates writing .ab files.

• Firmware Update: Ensure your device’s firmware is up-to-date, as manufacturers may release patches to fix such issues.

Alternative Solutions for Specific Scenarios

Depending on your development environment and tools, there are additional solutions to consider:

• MSBuild Adjustments: For Samsung S6 devices using MSBuild, modify the project file to change the EmbedAssembliesIntoApk setting from false to true.
• Debugger Configuration: In Delphi 10.2 environments, use the -autolaunch parameter in the Debugger configuration.
• Visual Studio Settings: Uncheck “Use Fast Deployment” in Visual Studio 2022 to resolve deployment issues.
