read(bytes);
str = EncodingUtils.getString(bytes,"UTF-8");
fin.close();
}
catch(Exception e){
e.printStackTrace();
}
return str;
}
(4) sdcard目录下的文件存取（/mnt/sdcard/）
使用FileOutputStream写文件：
public void writeFile2Sdcard(String fileName,String message){
try{
FileOutputStream fout = new FileOutputStream(fileName);
byte [] bytes =message.getBytes();
fout.write(bytes);
fout.close();
}
catch(Exception e){
e.printStackTrace();
}
}
使用FileInputStream读文件：
public String readFileFromSdcard(String fileName){
String res="";
try{
FileInputStream fin = newFileInputStream(fileName);
int length =fin.available();
byte [] buffer = newbyte[length];
fin.read(buffer);
res =EncodingUtils.getString(buffer, "UTF-8");
fin.close();
}
catch(Exception e){
e.printStackTrace();
}
return res;
}
