Save a file in the app folder using extension

[Marco_Perrone]

Hi,
I am creating an extension and one task is save a file in the app folder here the code that I use:

In the app folder i don't find the file, the DefaultFileScope is App
if I use
File pngFile = new File("sdcard/TeamLogo.png");
instead of
File pngFile = new File(activity.getFilesDir(), fileName);
the file is createad correctly

Thank You for help
Best Regards

@Marco_Perrone

activity.getFilesDir(),

Pass null as argument.

If you are interested more in working with files, please have a look.

Hi @vknow360,
sorry is not clear, for me, when You say:
activity.getFilesDir()
Pass null as argument
what I should do?
Thank You
Marco

@Marco_Perrone

activity.getFilesDir()
Pass null as argument

Sorry my mistake.
I misinterpreted getFilesDir as getExternalFilesDir.

@Marco_Perrone

File pngFile = new File(activity.getFilesDir(), fileName);

It also creates files but you can't view it normally in File Manager. It is stored in Internal Storage which is viewable only with root.

This is the path where I try to store the file but I can't see the image, so I don't know if the image is correctly saved or what

Here is some example code I have that returns an asset file (as a tempFile - in that same directory), you will see that this is all done "inside" the extension

@SimpleFunction(description = "Returns asset as File. This works only for a compiled app. Your file must have an extension, and there should be no 'dots' " +
          "in the file other than the one that " +
          "separates the name from the extension")
  public String GetAsset(String filename) throws IOException {

    File file = File.createTempFile("temp", ("." + filename.split("\\.")[1].toLowerCase()));
    filePath = file.getAbsolutePath();

    InputStream in = context.getAssets().open(filename);
    int size = in.available();
    byte[] buffer = new byte[size];
    in.read(buffer);
    in.close();

    FileOutputStream out = new FileOutputStream(filePath);
    out.write(buffer);
    out.close();

    return filePath;
  }

Hopefully this doesn't serve to further confuse

Hi @TIMAI2 ,
thank You for your help, in my case
int size = in.available(); is 0
I suppose because my InputStream is = httpConn.getInputStream
and in your case
InputStream in = context.getAssets().open(filename);

Anyway, I found the problem, the file was create correctly in the ASD folder with my extension but to display the image if I use the absolute path:
data/user/0/app//files/fileName.png
the file is not shown in the image component
Instead if I use the full path:
file:///data/user/0/app//files/fileName.png
The file is correctly shown int the image component.

Best Regards
