This programming - * model is direct, lightweight, but constraining. - * - * The 'android_native_app_glue' static library is used to provide a different - * execution model where the application can implement its own main event - * loop in a different thread instead. Here's how it works: - * - * 1/ The application must provide a function named "android_main()" that - * will be called when the activity is created, in a new thread that is - * distinct from the activity's main thread. - * - * 2/ android_main() receives a pointer to a valid "android_app" structure - * that contains references to other important objects, e.g. the - * ANativeActivity obejct instance the application is running in. - * - * 3/ the "android_app" object holds an ALooper instance that already - * listens to two important things: - * - * - activity lifecycle events (e.g. "pause", "resume"). See APP_CMD_XXX - * declarations below. - * - * - input events coming from the AInputQueue attached to the activity. - * - * Each of these correspond to an ALooper identifier returned by - * ALooper_pollOnce with values of LOOPER_ID_MAIN and LOOPER_ID_INPUT, - * respectively. - * - * Your application can use the same ALooper to listen to additional - * file-descriptors. They can either be callback based, or with return - * identifiers starting with LOOPER_ID_USER. - * - * 4/ Whenever you receive a LOOPER_ID_MAIN or LOOPER_ID_INPUT event, - * the returned data will point to an android_poll_source structure. You - * can call the process() function on it, and fill in android_app->onAppCmd - * and android_app->onInputEvent to be called for your own processing - * of the event. - * - * Alternatively, you can call the low-level functions to read and process - * the data directly... look at the process_cmd() and process_input() - * implementations in the glue to see how to do this. - * - * See the sample named "native-activity" that comes with the NDK with a - * full usage example.
