Struct android_activity::AndroidApp

pub struct AndroidApp { /* private fields */ }

Implementations

impl AndroidApp

pub fn native_window<'a>(&self) -> Option<NativeWindow>

Queries the current NativeWindow for the application.

This will only return Some(window) between [AndroidAppMainEvent::InitWindow] and [AndroidAppMainEvent::TerminateWindow] events.

pub fn poll_events<F>(&self, timeout: Option<Duration>, callback: F) where
    F: FnMut(PollEvent<'_>), 

Polls for any events associated with this AndroidApp and processes those events (such as lifecycle events) via the given callback.

It’s important to use this API for polling, and not call [ALooper_pollAll] directly since some events require pre- and post-processing either side of the callback. For correct behavior events should be handled immediately, before returning from the callback and not simply queued for batch processing later. For example the existing NativeWindow is accessible during a MainEvent::TerminateWindow callback and will be set to None once the callback returns, and this is also synchronized with the Java main thread. The MainEvent::SaveState event is also synchronized with the Java main thread.

pub fn create_waker(&self) -> AndroidAppWaker

Creates a means to wake up the main loop while it is blocked waiting for events within [poll_events()].

pub fn config(&self) -> ConfigurationRef

Returns a (cheaply clonable) reference to this application’s [Configuration]

pub fn content_rect(&self) -> Rect

Queries the current content rectangle of the window; this is the area where the window’s content should be placed to be seen by the user.

pub fn asset_manager(&self) -> AssetManager

Queries the Asset Manager instance for the application.

Use this to access binary assets bundled inside your application’s .apk file.

pub fn enable_motion_axis(&self, axis: Axis)

pub fn disable_motion_axis(&self, axis: Axis)

pub fn input_events<'b, F>(&self, callback: F) where
    F: FnMut(&InputEvent), 

pub fn sdk_version() -> i32

The user-visible SDK version of the framework

Also referred to as Build.VERSION_CODES

pub fn internal_data_path(&self) -> Option<PathBuf>

Path to this application’s internal data directory

pub fn external_data_path(&self) -> Option<PathBuf>

Path to this application’s external data directory

pub fn obb_path(&self) -> Option<PathBuf>

Path to the directory containing the application’s OBB files (if any).

Trait Implementations

impl Clone for AndroidApp

fn clone(&self) -> AndroidApp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AndroidApp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for AndroidApp

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<AndroidApp> for AndroidApp

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
