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:

Intent intent = new Intent(android.provider.Settings.ACTION_ACCESSIBILITY_SETTINGS); startActivityForResult(intent, 0); 

But I don't have any idea on how to enable the services listed in the view through my code.

Please, provide me your views.

Answer 1

I found a solution worked for me by calling

Settings.Secure.putString(getContentResolver(),      Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES, "pkgname/classname"); Settings.Secure.putString(getContentResolver(),      Settings.Secure.ACCESSIBILITY_ENABLED, "1"); 

Where the pkgname is your package name and the classname is the class name of your accessibility service.

If you need to enable several services or you don't want to destory the previous settings you might want to use : to seperate other services.

Also you might need to run as a system application and you might need the following permissions

<uses-permission android:name="android.permission.WRITE_SETTINGS" /> <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" /> 

However, according to @Rupert Rawnsley this might not work on some versions of Android, I am working on Android 4.0.4 and hope it works for you.

PS. If it doesn't work, maybe you could find some luck in /data/data/com.android.providers.settings/databases/settings.db/secure, that's where Android stores secure settings.

From Android 6.0 you can use:

adb shell settings put secure enabled_accessibility_services packagname/servicename 

The settings.db from old releases is no longer present on Android 6.0.
