c++ Android Native：如何在没有android_native_app_glue.h的情况下正确处理输入？

我正在尝试创建一个原生Android应用程序，而不使用NDK的粘合代码，以避免创建新线程，而是像普通应用程序一样保持单线程。在docs中描述了这一点，但是，我不知道它的示例。
我已经把一些东西在一起的帮助下胶水代码的工作，但一旦我刷卡和释放，而这样做，它触发了一个ANR。缓慢的滑动和点击工作正常。
在单线程中处理输入的最佳方式是什么？
当前代码：

static int on_input_queue_event(int fd, int events, void* data) {
  LOGI("got events: %d", events);
  App* app = data;
  for (int i=0; i<events; i++) {
    uint64_t stuff;
    size_t count = read(fd, &stuff, 8);
    LOGI("%llu <-%d->", stuff, count);
    AInputEvent* event;
    int result = AInputQueue_getEvent(app->input_queue, &event);
    if (result < 0) {
      LOGE("something went wrong");
      break;
    }
    AInputQueue_finishEvent(app->input_queue, event, 1);
  }
  // 0: unregister callback; 1: keep doing work
  return 1;
}

static void on_input_queue_created(ANativeActivity* activity, AInputQueue* queue) {
  LOGI("on_input_queue_created");
  App* app = activity->instance;
  app->input_queue = queue;
  ALooper* looper = ALooper_prepare(0);
  AInputQueue_attachLooper(queue, looper, 1, on_input_queue_event, app);
}

static void on_input_queue_destroyed(ANativeActivity* activity, AInputQueue* queue) {
  LOGI("on_input_queue_destroyed");
  App* app = activity->instance;
  app->input_queue = NULL;
  AInputQueue_detachLooper(queue);
}

Logcat：

got events: 1
0 <-1->
[...]
got events: 1
0 <-1->
[mouse button up while still swiping]
[new events not popping up any more]

这似乎起作用：

  • 忽略fd
  • 忽略events
  • 只读取输入队列直到它返回<0
static int on_input_queue_event(int fd, int events, void* data) {
  App* app = data;
  AInputEvent* event;
  while (AInputQueue_getEvent(app->input_queue, &event) >= 0) {
    // handle event
    AInputQueue_finishEvent(app->input_queue, event, 1);
  }
  return 1;
}
