installFlags
Raw Android install flags mask, 0 by default. All Int bit patterns are accepted.
The mask is ORed with platform flags before boolean options. Boolean options take precedence for their corresponding bits, including clearing bits when false. The boolean values remain independent of this mask. Setting the mask replaces the previous supplied mask; unrelated platform flags are preserved.
Setting this value is a delicate API: flags availability and behavior may depend on the Android version and backend permissions. Supplying flags grants no additional privileges.
