App decision

A decision block that start an app activity.

The fiber will pause until the activity has finished or the timeout expired. If you don’t want the fiber to pause, use the App start block instead.

Only some app activities are designed to return a meaningful result, those activities often perform a single task, like picking, inserting or deleting content.

An app activity is referred, either explicitly by its package and activity class, e.g. by using the Pick activity button, or implicitly by an action and data URI. Explicit start is seldom needed and should be avoided as it will stop working if the activity class is renamed. To implicitly start the “main” activity like the launcher does, specify only the package.

What data, actions and extras an activity support varies. Search for public documentation, or look at the app manifest for clues. Information about common Intents.

When including a file URI either as data URI or "android.intent.extra.STREAM" extra, ensure to enable the appropriate Grant flags otherwise it may be inaccessible to the app.

Note! If this block cause a ActivityNotFoundException or SecurityException failure is likely because the activity isn’t exported, it’s been temporarily or permanently disabled, or it’s secured by a permission to prevent third-party apps from launching it.
