[Root] Set Long-Press Home Button Action

आवाज सहायक सेट (लंबी प्रेस होम बटन एक्शन) प्रोग्राम

*** THIS TOOL NEEDS ROOT PERMISSION: IT WON'T WORK WITHOUT PROPERLY SETUP ***

This is a small tool to set voice assistant (long press home button action) programmatically.

You always need to install this tool into /system/priv-app/, otherwise it won't work. This is usually achievable by using root explorer on rooted device or third-party recovery.

Usually you do not need this tool unless your rom blocks you from setting voice assistant or automatically reset the setting.

Simply clicking on the shortcut of this app will set the voice assistant to Google Search. You may also use other voice assistant by executing,

am start --user 0 -d "set-assistant://org.gemini.set-assistant/foo/bar/bar/foo" "org.gemini.set_assistant/.SetAssistantActivity"

Refer to the screenshots or sample at

https://github.com/Hzj-jie/android-init/blob/master/sample/set-assistant.sh

This app sets following three settings,

assistant

voice_interaction_service

voice_recognition_service

into the value provided by intent or the default value as Google Search.

and sets following two settings,

assist_structure_enabled

assist_screenshot_enabled

to 1.

This application is efficient and small: it does what it needs to do and exit. So you may need to use some other tools to start it automatically.

I am using "Event based script runner" at https://play.google.com/store/apps/details?id=org.gemini.init to execute this tool when resuming the device. You may refer to the sample at,

https://github.com/Hzj-jie/android-init/blob/master/sample/screen-on.sh

and
