Activate blocking mode programmatically

Question

since Android 4.2 (I guess) there is the new blocking mode feature.

I'd like to toggle (activate/deactivate) this feature from my app. I know that I can change basically everything about sounds via the SDK but I couldn't find a single article about how to toggle blocking mode.

Answer 1

That is not from stock Android. Whatever it is comes from your device manufacturer. You will have to ask them what that is and whether or not there is an API for controlling it that ordinary SDK apps can hold.
