Resolving Appium's SecurityException: A Guide to Adjusting Device Settings

5 April 2024 Stephan Petzl Leave a comment Tech-Help

When automating mobile applications using Appium, encountering errors is not uncommon. One such error that developers might face is a java.lang.SecurityException, specifically when attempting to inject events into another application. This error typically occurs during the use of the TouchAction class in Appium and can be quite perplexing. However, the resolution is often simpler than one might expect.

Understanding the SecurityException Error

The error message in question is:

java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS permission

This exception is thrown when your automation script attempts to perform a touch action, but the security settings on the mobile device prevent it from doing so. Appium requires certain permissions to interact with the device, and without these permissions, it cannot execute the necessary actions.

Step-by-Step Solution

To resolve this issue, you need to modify the security settings on your mobile device. Follow these steps to adjust the necessary settings:

  1. Navigate to the Settings application on your mobile device.
  2. Scroll down and select Additional settings (this may vary depending on your device).
  3. Find and tap on Developer options. Note: If you do not see Developer options, you may need to enable it by tapping on the Build number in the About phone section several times until you see a message that Developer options have been enabled.
  4. Within Developer options, look for USB Debugging Security settings or a similar option that controls the security settings for USB debugging.
  5. Enable the option that allows security settings for USB debugging.

By enabling this option, you grant the necessary permissions for Appium to inject touch events into your mobile application, thereby resolving the java.lang.SecurityException.


It’s important to remember that this solution pertains to the specific error of requiring INJECT_EVENTS permission when using the TouchAction class in Appium. If you encounter different errors or if the above steps do not resolve your issue, there may be other factors at play. However, adjusting the developer options is a common and often overlooked solution that can save time and frustration during your mobile application testing process.
