Public methods
public void onBackgroundThreadGlContextCreated()Called once a background thread when a new GL context is created on the background thread, before any subsequent calls to render. Note this function is called inside a lambda passed to runBackgroundThreadGlCommands which has synchronized access to the GL context.
If you need to override this method in java, consider using androidx.wear.watchface.ListenableGlesRenderer instead.
public voidonUiThreadGlSurfaceCreated(@Px int width, @Px int height)
Called when a new GL surface is created on the UiThread, before any subsequent calls to render or in response to SurfaceHolder.Callback.surfaceChanged. Note this function is called inside a lambda passed to runUiThreadGlCommands which has synchronized access to the GL context.
If you need to override this method in java, consider using androidx.wear.watchface.ListenableGlesRenderer instead.
@WorkerThread
public final voidrunBackgroundThreadGlCommands(@NonNull Runnable runnable)
Inside of a Mutex this function sets the GL context associated with the WatchFaceService.getBackgroundThreadHandler's looper thread as the current one, executes runnable and finally unsets the GL context.
Access to the GL context this way is necessary because GL contexts are not shared between renderers and there can be multiple watch face instances existing concurrently (e.g. headless and interactive, potentially from different watch faces if an APK contains more than one WatchFaceService).
NB this function is called by the library before running runBackgroundThreadGlCommands so there's no need to use this directly in client code unless you need to make GL calls outside of those methods.

Protected methods
protected @NonNull ListenableFuture<Unit>onBackgroundThreadGlContextCreatedFuture()
Called once a background thread when a new GL context is created on the background thread, before any subsequent calls to render. Note this function is called inside a lambda passed to runBackgroundThreadGlCommands which has synchronized access to the GL context. Note cancellation of the returned future is not supported.

@UiThread
protected @NonNull ListenableFuture<Unit>onUiThreadGlSurfaceCreatedFuture(@Px int width, @Px int height)
Called when a new GL surface is created on the UiThread, before any subsequent calls to render and in response to SurfaceHolder.Callback.surfaceChanged. Note this function is called inside a lambda passed to Renderer.GlesRenderer.runUiThreadGlCommands which has synchronized access to the GL context. Note cancellation of the returned future is not supported.
