## 枚举类型说明

anonymous enum

枚举值
LOOPER_ID_MAIN | Looper data ID of commands coming from the app's main thread, which is returned as an identifier from ALooper_pollOnce(). The data for this identifier is a pointer to an android_poll_source structure. These can be retrieved and processed with android_app_read_cmd() and android_app_exec_cmd().
LOOPER_ID_INPUT | Looper data ID of events coming from the AInputQueue of the application's window, which is returned as an identifier from ALooper_pollOnce(). The data for this identifier is a pointer to an android_poll_source structure. These can be read via the inputQueue object of android_app.
LOOPER_ID_USER | Start of user-defined ALooper identifiers.

anonymous enum

枚举值
APP_CMD_INPUT_CHANGED | Command from main thread: the AInputQueue has changed. Upon processing this command, android_app->inputQueue will be updated to the new queue (or NULL).
APP_CMD_INIT_WINDOW | Command from main thread: a new ANativeWindow is ready for use. Upon receiving this command, android_app->window will contain the new window surface.
APP_CMD_TERM_WINDOW | Command from main thread: the existing ANativeWindow needs to be terminated. Upon receiving this command, android_app->window still contains the existing window; after calling android_app_exec_cmd it will be set to NULL.
APP_CMD_WINDOW_RESIZED | Command from main thread: the current ANativeWindow has been resized. Please redraw with its new size.
APP_CMD_WINDOW_REDRAW_NEEDED | Command from main thread: the system needs that the current ANativeWindow be redrawn. You should redraw the window before handing this to android_app_exec_cmd() in order to avoid transient drawing glitches.
APP_CMD_CONTENT_RECT_CHANGED | Command from main thread: the content area of the window has changed, such as from the soft input window being shown or hidden. You can find the new content rect in android_app::contentRect.
APP_CMD_GAINED_FOCUS | Command from main thread: the app's activity window has gained input focus.
APP_CMD_LOST_FOCUS | Command from main thread: the app's activity window has lost input focus.
APP_CMD_CONFIG_CHANGED | Command from main thread: the current device configuration has changed.
APP_CMD_LOW_MEMORY | Command from main thread: the system is running low on memory. Try to reduce your memory use.
APP_CMD_START | Command from main thread: the app's activity has been started.
APP_CMD_RESUME | Command from main thread: the app's activity has been resumed.
APP_CMD_SAVE_STATE | Command from main thread: the app should generate a new saved state for itself, to restore from later if needed. If you have saved state, allocate it with malloc and place it in android_app.savedState with the size in android_app.savedStateSize. The will be freed for you later.
APP_CMD_PAUSE | Command from main thread: the app's activity has been paused.
APP_CMD_STOP | Command from main thread: the app's activity has been stopped.
APP_CMD_DESTROY | Command from main thread: the app's activity is being destroyed, and waiting for the app thread to clean up and exit before proceeding.

## 函数说明

void android_app_post_exec_cmd | ( | struct android_app * | android_app,
|  | int8_t | cmd
| ) |  |

Call with the command returned by android_app_read_cmd() to do the final post-processing of the given command. You must have done your own actions for the command before calling this function.

void android_app_pre_exec_cmd | ( | struct android_app * | android_app,
|  | int8_t | cmd
| ) |  |

Call with the command returned by android_app_read_cmd() to do the initial pre-processing of the given command. You can perform your own actions for the command after calling this function.

int8_t android_app_read_cmd | ( | struct android_app * | android_app | ) |

Call when ALooper_pollAll() returns LOOPER_ID_MAIN, reading the next app command message.

void android_main | ( | struct android_app * | app | ) |

This is the function that application code must implement, representing the main entry to the app.

void app_dummy | ( |  | ) |

Dummy function you can call to ensure glue code isn't stripped.
