android.os.FileObserver

Here are the examples of the java api class android.os.FileObserver taken from open source projects.

1. PFileIO#observeFolder()

Project: Protocoder
File: PFileIO.java
@ProtoMethod(description = "Observer file changes in a folder", example = "")
@ProtoMethodParam(params = { "path", "function(action, file" })
public void observeFolder(String path, final FileObserverCB callback) {
    fileObserver = new FileObserver(ProjectManager.getInstance().getCurrentProject().getStoragePath() + "/" + path, FileObserver.CREATE | FileObserver.MODIFY | FileObserver.DELETE) {

        @Override
        public void onEvent(int event, String file) {
            if ((FileObserver.CREATE & event) != 0) {
                callback.event("create", file);
            } else if ((FileObserver.DELETE & event) != 0) {
                callback.event("delete", file);
            } else if ((FileObserver.MODIFY & event) != 0) {
                callback.event("modify", file);
            }
        }
    };
    fileObserver.startWatching();
}

2. MainActivity#onCreate()

Project: Protocoder
File: MainActivity.java
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mContext = this;
    //if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    //    Window w = getWindow(); // in Activity's onCreate() for instance
    //    w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
    //    w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    //}
    setContentView(R.layout.activity_main);
    setToolbar();
    mProtocoder = Protocoder.getInstance(this);
    mProtocoder.init();
    // Get and store the application context
    AppRunnerContext.get().init(getApplicationContext());
    /*
        *  Views
        */
    if (savedInstanceState == null) {
        addFragments();
    } else {
        mProtocoder.protoScripts.reinitScriptList();
    }
    // Check when mContext file is changed in the protocoder dir
    fileObserver = new FileObserver(ProjectManager.FOLDER_USER_PROJECTS, FileObserver.CREATE | FileObserver.DELETE) {

        @Override
        public void onEvent(int event, String file) {
            if ((FileObserver.CREATE & event) != 0) {
                MLog.d(TAG, "File created [" + ProjectManager.FOLDER_USER_PROJECTS + "/" + file + "]");
            // check if its mContext "create" and not equal to probe because
            // thats created every time camera is
            // launched
            } else if ((FileObserver.DELETE & event) != 0) {
                MLog.d(TAG, "File deleted [" + ProjectManager.FOLDER_USER_PROJECTS + "/" + file + "]");
            }
        }
    };
    connectivityChangeReceiver = new ConnectivityChangeReceiver();
}
