Enum android_manifest::DocumentLaunchMode

pub enum DocumentLaunchMode {
    IntoExisting,
    Always,
    None,
    Never,
}

Four values which produce the following effects when the user opens a document with the application

Variants

IntoExisting

The system searches for a task whose base intent’s ComponentName and data URI match those of the launching intent. If the system finds such a task, the system clears the task, and restarts with the root activity receiving a call to onNewIntent(android.content.Intent). If the system does not find such a task, the system creates a new task.

Always

The activity creates a new task for the document, even if the document is already opened. This is the same as setting both the FLAG_ACTIVITY_NEW_DOCUMENT and FLAG_ACTIVITY_MULTIPLE_TASK flags.

None

The activity does not create a new task for the activity. This is the default value, which creates a new task only when FLAG_ACTIVITY_NEW_TASK is set. The overview screen treats the activity as it would by default: it displays a single task for the app, which resumes from whatever activity the user last invoked.

Never

This activity is not launched into a new document even if the Intent contains FLAG_ACTIVITY_NEW_DOCUMENT. Setting this overrides the behavior of the FLAG_ACTIVITY_NEW_DOCUMENT and FLAG_ACTIVITY_MULTIPLE_TASK flags, if either of these are set in the activity, and the overview screen displays a single task for the app, which resumes from whatever activity the user last invoked.
