在内部存储Android文件未找到 [英] Android File on Internal Storage not found

问题描述

我想写我的应用程序的Andr​​oid内部存储空间的文件。如此多的试验后，我用这个方法<一终于成功href=\"http://stackoverflow.com/questions/9306155/writing-reading-files-to-from-android-phones-internal-memory\">Writing/Reading文件到/从Android手机的内部存储器。然而，当我去到的数据/数据​​/包名/文件，我找不到我的包，甚至无法找到MyFile.txt的。事实上，我不能在内部存储器中的任何地方找到他们。这是为什么？

解决方案

 字符串的root = Environment.getExternalStorageDirectory（）的toString（）;
 文件f =新的文件（根+/ yourDirectoryname）;
 myDir.mkdirs（）;档案文件=新的文件（MYDIRyourfilename.txt）;
FOS的FileOutputStream =新的FileOutputStream（文件）;
ObjectOutputStream的OOS =新的ObjectOutputStream（FOS）;
          oos.writeObject（对象）;
          oos.close（）;
          fos.close（）;
 

添加此code编写

I'm trying to write a file in my app's android internal storage space. After so many trials, I was finally successful using this method Writing/Reading Files to/from Android phone's internal memory . However, when I go to data/data/package_name/files, I cannot find my package, and cannot even find the MyFile.txt. In fact, I can't find them anywhere in internal memory. Why is that?

解决方案

String root = Environment.getExternalStorageDirectory().toString(); 
 File f = new File(root + "/yourDirectoryname");  
 myDir.mkdirs();    

File file = new File (myDir, "yourfilename.txt");
FileOutputStream fos = new FileOutputStream(file);
ObjectOutputStream oos = new ObjectOutputStream(fos);
          oos.writeObject(object);
          oos.close();
          fos.close();
