commit 2bf110d691053353d6cb06ad2bbd1b78fef60f19
Author: Tor Lillqvist <tlillqvist at suse.com>

Rework the bootstrap mechanism of a LO program on Android
Do use NativeActivity and android_native_app_glue after all.
I hope this enables us to have a "message pump" (a loop that typically
would call ALooper_pollAll()) inside the LO "program" being run, as
expected by LO code.
(On Android, a "program", even one mostly implemented in native code,
is actually a shared library loaded by the main Java code of an app.)
The android_native_app_glue code and the android_main() it calls
belongs in the bootstrap library, though. Not in SAL_MAIN_IMPL.
The earlier idea, having a "normal" Java Activity subclass, would mean
events come in as method calls to that class. To then turn those into
something the LO code can "get", we would have effectively had to
re-implement what android_native_app_glue does anyway.

+/**
+ * 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 'threaded_native_app' 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.
+ *

-/**
- * 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 'threaded_native_app' 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. Also look at the JavaDoc of NativeActivity.
