Source of Android's lock screen

Posted by: admin April 23, 2020 Leave a comment


I am looking for the source code of the android lock screen. It can be for any version of Android (1.5, 1.6, 2.0, etc).

I tried looking in the repository at: https://android.googlesource.com/, but it doesn’t look like it’s under platform/frameworks/base. Maybe it’s closed source?

How to&Answers:

Do an actual full checkout of the source according to Google’s directions.

As of Android 4.2, the keyguard source is at frameworks/base/policy/src/com/android/internal/policy/impl/keyguard. There’s a mirror on GitHub you can look at online (I pegged this link to the JB MR 1.1 release in case the location changes again in a future release).

When this question was originally answered, Android 2.3 and lower had their lockscreen source at frameworks/policies/base/phone/com/android/internal/policy/impl.
You can also view these sources online in their GitHub mirror; that source is still kicking in the current repo, but hasn’t been updated in several years.


For those who are on kitkat (android 4.4) or above source code, it seems the code has been moved to
