Delete image saved using private mode

Question

I'm saving a Bitmap in order to send the file name to another activity. This is the code I'm using to do this:

@Nullable
public static String saveImage(Context context, Bitmap bitmap, int pos, String TAG)
{
    String fileName = "thumbnail_" + pos + ".png";

    try
    {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
        byte[] byteArray = stream.toByteArray();

        FileOutputStream fileOutStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
        fileOutStream.write(byteArray);

        fileOutStream.close();

    } catch (IOException ioe) {
        ioe.printStackTrace();
        Log.e(TAG, "Error guardando la imagen");

        return null;
    }

    return fileName;
}

What I want to do is when exiting the activity, delete this image. How can I know where this image has been saved and how can I delete it?

Thanks in advance,

Answer 1

fileName is the path to your file in your app internal storage and your Context has a method called deleteFile(String name) where name is your fileName .

So, just call context.deleteFile(fileName) .

You can check the documentation here .
