App creates extra folder if name has spaces

[Ruben Matt]

Hi.

In my android app the when the user create a project, it's created a folder in the external storage to later save the photos. If the name has no spaces everything works fine but when i put a name with spaces in the beggining it creates the folder but when i take a photo and save it the app creates an extra folder with for exmple, android%20app, it add the "%20" part i dont know why.

Creating the project:

File projeto = new File(Environment.getExternalStorageDirectory()+"/PROJETOS/"+txNomeProjeto.getText().toString());
				if(!projeto.exists()){
					projeto.mkdir();
					Toast.makeText(getApplicationContext(), "Projeto Criado na pasta principal", Toast.LENGTH_LONG).show();
				

Taking the photo in the project with spaces:

Bundle b = getIntent().getExtras();
		nome = (String)  b.get("nome_projecto"); //SAVES THE PROJECT NAME
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
								File file = new File(Environment.getExternalStorageDirectory()+"/PROJETOS/"+nome+"/"+"proj"+id+"_reg"+id_reg+"_"+valor+".jpg");
								nome_caminho = "proj"+id+"_reg"+id_reg+"_"+valor+".jpg";
								outputFileUri = Uri.fromFile(file);
								intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
								startActivityForResult(intent, TAKE_PICTURE);

The obvious first question would be: why save something with spaces in it? Can you replace those with hyphens or underscores?

Thanks for replying.

I think i can do that, just have to ask.
I actually never thought of that, but i would have to save the project's name in the DB also with the underscore or the hyphen right??

The DB should have no problems with spaces in strings.

Where does this "project name" come from? What I generally do is to keep the name of the directory where I store files on the device as a string in values/strings.xml. That way it's easily accessible in the app.

the project name comes from the listview, is where i show all the projects

If this was my project, I think I'd store the files in predictably-named directories (maybe numbered) within a central app directory. Then the mapping between directory numbers and projects can be stored in the DB, or in shared prefs (if it's not too many), or maybe in a file by itself if you don't want to use the DB.

That's actually what i'm doing, it's not numbered folders but it's all saved in a central app folder. And the mapping between the folders and the projects it's stored in the DB.
