Camera lags when OpenPDroid is installed, regardless of settings #3

Open wsot opened 11 years ago

wsot commented 11 years ago

When OpenPdroid is installed, the phone lags a lot when the camera app is open.

This is due to the database being rapidly opened and closed by the PrivacyPersistenceAdapter. It hadn't occurred in the past because a bug in the PrivacyPersistenceAdapter (since the very original PDroid) prevented the 'idle database closing' code triggering. When this bug was fixed, the database started being opened and closed very rapidly - which is what it was designed to do, but kills performance.

An experimental fix is in the jb-mr1-release-openpdroid-devel branches, and cm10.1 and aokp jb-mr1 equivalents. This fix does not prevent the database from opening and closing (which will probably be modified in future) but rather adds a least-recently-used clearing cache to reduce database calls.

I can confirm the lag in CM10.1 (galaxy nexus - maguro), however, on JR12 (Paul O'Brien)'s 4.2.1 it isn't, the camera works great.

This has been fixed in the latest development branch, and will be included in the next release.
