问题
I want to test the accessibility of my app in emulator (particularly Talkback) but it seems that the option is missing in emulator. Here is the screen shot from the emulator in accessibility settings:
There are two options "ClockBack" and "QueryBack" which I couldn't find on my phone with the same android version. Here is the screenshot of the accessibility setting of my phone:
I searched to learn about "ClockBack" and "QueryBack" to see if they are replacement of Talkback in emulator but I couldn't find anything.
Does any one know what is the functionality of "ClockBack" and "QueryBack"? And more over how to enable Talkback in emulator?
回答1:
It seems that the emulator doesn't contain Talkback by default so after downloading "TalkBack" apk and install it on the emulator, the option has been enabled.
回答2:
Update: It's easier to install the Android Accessibility Suite from the Google Play Store. It will update your Settings->Accessibility menu to include TalkBack as an option.
