如何在Android中以编程方式隐藏文件夹并访问其中的文件。

Question

I am developing android application which having some external files. I want to hide these files. Can we access hidden file in my app. Example I have many of images which will be use in my app. I want to hide these file but access only using my app.

Answer 1

Just put a . in front of your folder name than it becomes a hidden folder

Answer 2

Android is multi user linux system, so if you create folder starting with dot , it'll be hidden.

So store folder starting with dot

for example

File folder = new File(Environment.getExternalStorageDirectory(), ".hiddenFolder");
folder.mkdir();

and store all images in this folder and access images in your app from same folder.

Answer 3

Create a folder with a . (dot) before its name, and add an empty .nomedia file inside it. (.(dot)nomedia - exactly as I typed it) and add your files ands images there.

Now other Apps like Gallery will ignore these images. That's the only way that I think this can be done.

Eg: folder name: .images

which includes an empty file .nomedia
