Starting March 27, 2025, we recommend using android-latest-release instead of aosp-main to build and contribute to AOSP. For more information, see Changes to AOSP.
Package Manager Configuration (deprecated)
Stay organized with collections
Save and categorize content based on your preferences.
The dexopt implementation in the package manager only applies to Android
13 and lower. In Android 14, it is replaced by ART
Service, and it will be removed from the package manager in the next version. For information about
configuring ART Service, see
ART Service Configuration.
Since Android 7.0, there's a generic way to specify the level of
compilation/verification that happened at various stages.
The compilation levels can be configured via system properties
with the defaults being:
pm.dexopt.install=speed-profileThis is the compilation filter used when installing applications through Google Play or other app
stores. We recommend the install filter be set to speed-profile in order to enable
the use of profiles from the dex metadata files (see
blog).
Note that if a profile isn't provided or if it is empty, speed-profile is equivalent
to verify.
pm.dexopt.bg-dexopt=speed-profile
This is the compilation filter used when the device is idle and charging. Try the
speed-profile compiler filter to take advantage of profile-guided compilation and save
on storage.
pm.dexopt.boot-after-ota=verify
The compilation filter used after an over-the-air update. We
strongly recommend the verify compiler filter for this
option to avoid very long boot times.
pm.dexopt.first-boot=verify-
The compilation filter for the first time the device ever boots. The filter
used here only affects the boot time after factory. We recommend the filter
verify for it to avoid long times before a user gets to
use the phone for the very first time. Note that if all applications in
the system image are already compiled with verify, speed-profile, or
speed with the right class loader context, the compilation on the first boot will be
skipped, and pm.dexopt.first-boot will have no effect.
