- * 3. when the ui is in an interactive state, no controls should ever move
- * 4. controls directly reference a memory location and use that as their

+/**
+ * The native activity interface provided by <android/native_activity.h>
+ * is based on a set of application-provided callbacks that will be called
+ * by the Activity's main thread when certain events occur.
+ *
+ * This means that each one of this callbacks _should_ _not_ block, or they
+ * risk having the system force-close the application. 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 object 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
