监控指定目录下的文件以及子目录及子目录下的文件，支持传参控制监控事件，主要使用linux inotify和epoll实现 4 | 5 | #### 注意事项 6 | demo中未申请存储权限，使用时需要手动打开或者申请存储权限 7 | 8 | #### 使用方式 9 | 10 | 11 | ```java 12 | 主要API： 13 | /** 14 | * Create a new file observer for a certain file or directory And start it. 15 | * @param path The file or directory to monitor 16 | * @param mask The event or events (added together) to watch for 17 | */ 18 | public FileObserverJni(String path, int mask, ILifecycle callback) //推荐使用 19 | 20 | /** 21 | * Equivalent to FileObserver(path, FileObserver.ALL_EVENTS). 22 | */ 23 | public FileObserverJni(String path) 24 | 25 | 26 | 例子： 27 | String path = Environment.getExternalStorageDirectory().getAbsolutePath(); 28 | Log.e(TAG, "onCreate: " + path); 29 | 30 | FileObserverJni fileObserverJni = new FileObserverJni(path, FileObserverJni.ALL_EVENTS, new FileObserverJni.ILifecycle() { 31 | @Override 32 | public void onInit(int errno) { 33 | if (0 == errno) { 34 | Log.e(TAG, "onInit: 初始化成功"); 35 | } else { 36 | Log.e(TAG, "onInit: 初始化失败: " + FileObserverJni.error2String(errno)); 37 | } 38 | } 39 | 40 | @Override 41 | public void onExit(int errno) { 42 | if (0 == errno) { 43 | Log.e(TAG, "onExit: 正常退出"); 44 | } else { 45 | Log.e(TAG, "onExit: 异常退出: " + errno); 46 | } 47 | } 48 | }); 49 | fileObserverJni.setmCallback(new FileObserverJni.Callback() { 50 | @Override 51 | public void FileObserverEvent(String path, int mask) { 52 | // 在这里监听事件 53 | switch (mask) { 54 | case FileObserverJni.CREATE: 55 | Log.e(TAG, "FileObserverEvent: 文件创建：" + path); 56 | break; 57 | case FileObserverJni.DELETE: 58 | Log.e(TAG, "FileObserverEvent: 文件删除：" + path); 59 | break; 60 | case FileObserverJni.MODIFY: 61 | Log.e(TAG, "FileObserverEvent: 文件修改：" + path); 62 | break; 63 | } 64 | } 65 | }); 66 | 67 | ``` 68 | 69 | 70 | 71 | #### 修改记录： 72 | 73 | ##### 2019/5/9 74 | 1.修改默认监听创建删除事件为可传入mask参数 75 | 2.修改使用接口，仿FileObserver 76 | 3.修改回调方法为统一方法回调 77 | 78 | 79 | 80 | ##### 适配发现 81 | 1.锤子坚果pro事件有问题，除了删除，其他都不好用 82 | 83 | 84 | 85 | ##### 2022/08/28 86 | 87 | 1. 修改项目为Androidx 88 | 2. 修改项目Android.mk 为CMakeLists.txt 89 | 3. 修正没有回调Java接口的bug 90 | 91 | ##### 2022/09/18 92 | 93 | 1. 增加初始化及退出回调 94 | 2. 增加错误码转换接口 95 | 3. 禁用Android Q 分区存储 96 | 4. 增加使用示例 97 | -------------------------------------------------------------------------------- /Tools/.gitignore:
