How to Programmatically Enable/Disable Accessibility Service in Android

Question

I would like to programmatically enable/disable Accessibility Services listed under Settings->Accessibility option.

I could start Accessibility Intent like below:

Answer 1

In instrumented tests I start my accessibility service like this:

private fun enableAccessibilityService() {
    val packageName = "com.example"
    val className = "$packageName.service.MyService"
    val string = "enabled_accessibility_services"
    val cmd = "settings put secure $string $packageName/$className"
    InstrumentationRegistry.getInstrumentation()
      .getUiAutomation(UiAutomation.FLAG_DONT_SUPPRESS_ACCESSIBILITY_SERVICES)
      .executeShellCommand(cmd)
      .close()
    TimeUnit.SECONDS.sleep(3)
}

I tested on Android 6 and 8. This also works for non-system apps.
