这是您的DCIM文件夹删除文件的问题的完整的解决方案。
This is the complete solution of your problem of deleting the file from dcim folder.
just copy and paste this method. And call it whenever necessary.
private void deleteLatest() {
// TODO Auto-generated method stub
File f = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera" );
//Log.i("Log", "file name in delete folder : "+f.toString());
File [] files = f.listFiles();
//Log.i("Log", "List of files is: " +files.toString());
Arrays.sort( files, new Comparator<Object>()
{
public int compare(Object o1, Object o2) {
if (((File)o1).lastModified() > ((File)o2).lastModified()) {
// Log.i("Log", "Going -1");
return -1;
} else if (((File)o1).lastModified() < ((File)o2).lastModified()) {
// Log.i("Log", "Going +1");
return 1;
} else {
// Log.i("Log", "Going 0");
return 0;
}
}
});
//Log.i("Log", "Count of the FILES AFTER DELETING ::"+files[0].length());
files[0].delete();
}
