InstallWindowed 2

Installs system updates (without user interaction) during a daily maintenance window. Set the start and end of the daily maintenance window, as minutes of the day, when creating a new TYPE_INSTALL_WINDOWED policy. See createWindowedInstallPolicy().

No connectivity, not enough disk space, or a low battery are typical reasons Android might not install a system update in the daily maintenance window. After 30 days trying to install an update in the maintenance window (regardless of policy changes in this period), the system prompts the device user to install the update.

Postpone 3

Postpones the installation of system updates for 30 days. After the 30-day period has ended, the system prompts the device user to install the update.

The system limits each update to one 30-day postponement. The period begins when the system first postpones the update and setting new TYPE_POSTPONE policies won’t extend the period. If, after 30 days the update isn't installed (through policy changes), the system prompts the user to install the update.

Note: Device manufacturers or carriers might choose to exempt important security updates from a postponement policy. Exempted updates notify the device user when they become available.
