大佬教程收集整理的这篇文章主要介绍了android – File Observer无法使用intent服务,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
我发现了一个很好的类来扩展抽象的File Observer类……
import android.os.FiLeobserver;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.httpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import android.util.Log;
public class FileSync extends FiLeobserver {
public String absolutePath;
public String uid;
public FileSync(String path,String uidd) {
super(path,FiLeobserver.all_EVENTS);
absolutePath = path;
uid = uidd;
}
@Override
public void onEvent(int event,String path) {
if (path == null) { //path is the name of the file... I think its absolute
return;
}
//a new file or subdirectory was created under the monitored directory
if ((FiLeobserver.CREATE & event)!=0) {
doFileUpload(path,uid);
}
//a file or directory was opened
if ((FiLeobserver.oPEN & event)!=0) {
//TODO Nothing... yet
}
//data was read from a file
if ((FiLeobserver.ACCESS & event)!=0) {
//TODO Nothing... yet
}
//data was written to a file
if ((FiLeobserver.MODIFY & event)!=0) {
doFileUpload(path,uid);
}
//someone has a file or directory open read-only,and closed it
if ((FiLeobserver.CLOSE_NowRITE & event)!=0) {
//TODO Nothing... yet
}
//someone has a file or directory open for wriTing,and closed it
if ((FiLeobserver.CLOSE_WRITE & event)!=0) {
doFileUpload(path,uid);
}
//[todo: consider combine this one with one below]
//a file was deleted from the monitored directory
if ((FiLeobserver.deletE & event)!=0) {
//TODO Remove file from the server
}
//the monitored file or directory was deleted,monitoring effectively stops
if ((FiLeobserver.deletE_SELF & event)!=0) {
//TODO Toast an error,recreate the folder,resync and restart monitoring
}
//a file or subdirectory was moved from the monitored directory
if ((FiLeobserver.MOVED_FROM & event)!=0) {
//TODO delete from the server
}
//a file or subdirectory was moved to the monitored directory
if ((FiLeobserver.MOVED_TO & event)!=0) {
doFileUpload(path,uid);
}
//the monitored file or directory was moved; monitoring conTinues
if ((FiLeobserver.MOVE_SELF & event)!=0) {
//TODO Recreate the folder and show toast
}
//Metadata (permissions,owner,timestamp) was changed explicitly
if ((FiLeobserver.ATTRIB & event)!=0) {
//TODO Nothing... Yet
}
}
我在Intentservice的onCreate中创建了三个这样的观察者,如下所示:
new File("/sdcard/Docs/").mkdir();
FileSync files = new FileSync("/sdcard/Docs/",uid);
FileSync pictures = new FileSync(Environment.DIRECTORY_PICTURES,uid);
FileSync music = new FileSync(Environment.DIRECTORY_MUSIC,uid);
files.startWatching();
pictures.startWatching();
music.startWatching();
不仅观察者不工作,而且mkdir功能不起作用.
有任何想法吗?谢谢!
