I searched for him and could not find a definition. As usual, the documentation on Android was very "lit."
In short, this is your lockscreen.
PIN, pattern, face, password lock or default lock (slide to unlock), but this is your lock screen.
Keyguard mainly refers to the code that handles unlocking the phone. it looks like a key lock on your Nokia phone a few years ago with a touch-screen utility.
you can find more detailed information that you look in android/app or com\android\internal\policy\impl
android/app
com\android\internal\policy\impl
Good luck
The lock screen works without keyguard, I tested it. The home button stops working, and you cannot get into the task manager while holding the home key. I wish they did not develop a new process when it was built into the ui system or something else. I do not see the need for change and additional process
Yes, I also found it here: http://developer.android.com/tools/testing/activity_testing.html It seems that the key protection mechanism includes a screen lock, but not only includes it. According to this web page, it also defines a key restriction for the Android autotest platform.
I accidentally deleted the keyboard. How can I restore it?
