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.
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.
