How to suppress talkback programmatically?

Question

Is there any way to make talkback to suppress when I open my application and resume when I stop my Application?

Answer 1

While typically you cannot toggle TalkBack from your app, it is possible if the user grants your app the "write secure settings" system permission from adb, since you can directly modify the flags that indicate to the system which accessibility services are enabled.
