Set screenlock setting interactively

adb, android, android-4.4-kitkat, cts, dragonboard

Solution

Got it figured out.

1. Update settings.db using adb shell

shell@msm8974:/ $ su
shell@msm8974:/ # sqlite3 /data/data/com.android.providers.settings/databases/settings.db
sqlite3> update secure set value=1 where name='lockscreen.disabled';
sqlite3> .quit

2. Move or delete locksettings files

shell@msm8974:/ # mkdir /data/system/lock
shell@msm8974:/ # mv /data/system/locksettings* lock

`adb reboot` and good to go.

Problem

I want to set the screenlock mode to None in KitKat so I can run CTS. I'm using the DragonBoard APQ8074 for development from Intrinsyc, and they just released their BSP for Android KitKat 4.4.2. Trouble is, it's unstable and the Security menu in Settings crashes. So I can't use `adb shell` to `input keyevents 19, 20, 21, 22, 23` to navigate. `adb shell settings` command seems like it should work for this, but it's not. I tried these commands against 4.2, 4.3 and 4.4, and they seem to assign the values, but they don't visually result in any changes. ``` shell@msm8974:/ $ settings get system lockscreen_disabled null shell@msm8974:/ $ settings put system lockscreen_disabled true shell@msm8974:/ $ settings get system lockscreen_disabled true shell@msm8974:/ $ settings get system screen_brightness 102 shell@msm8974:/ $ settings put system screen_brightness 255 shell@msm8974:/ $ settings get system screen_brightness 255 ``` Now I dunno if lockscreen_disabled is what I want, here, but Settings.java doesn't seem to provide a call to any sort of `unlock_mode`, so I dunno what else to do. I don't want to write an app to do this, I just want to set screen lock mode to `None` so I can run CTS. If I need to modify source, then make & flash a new image, I'm willing to do that, but I don't know what to modify. Thanks for any guidance.
