AppRegistry

AppRegistry is the JS entry point to running all React Native apps. App root components should register themselves with AppRegistry.registerComponent, then the native system can load the bundle for the app and then actually run the app when it's ready by invoking AppRegistry.runApplication.

To "stop" an application when a view should be destroyed, call AppRegistry.unmountApplicationComponentAtRootTag with the tag that was passed into runApplication. These should always be used as a pair.

AppRegistry should be required early in the require sequence to make sure the JS execution environment is setup before other modules are required.

registerHeadlessTask()

static registerHeadlessTask(taskKey, task)

Register a headless task. A headless task is a bit of code that runs without a UI. @param taskKey the key associated with this task @param task a promise returning function that takes some data passed from the native side as the only argument; when the promise is resolved or rejected the native side is notified of this event and it may decide to destroy the JS context.

startHeadlessTask()

static startHeadlessTask(taskId, taskKey, data)

Only called from native code. Starts a headless task.

@param taskId the native id for this task instance to keep track of its execution @param taskKey the key for the task to start @param data the data to pass to the task
