It works on Android 5.0+ devices, but does not work on Android 4.4.2

I’m writing an automation script using AndroidDriver. It works on Android 5.0+ devices, but does not work on Android 4.4.2.

The app is installed and running on an Android 4.4.2 device, but WebElement’s click () or sendKeys () do nothing. The AndroidDriver session is being maintained. NoSuchElementException does not occur. What is the cause? I want to know the solution.
