Is there a way to make sure that the folders that my Android application creates are not visible and accessible in another application. For example, my application created 2 file folders. I go through some file manager and they are not displayed there.

    So do not create directories in directories accessible to all applications (sdcard, etc.); use as a parent directory for your directories the result of a call to Context.getFilesDir () or Context.getCacheDir () (depending on the task).

    • I create folders Encrypt and Decrypt there will be stored encrypted files. - Evilleks
    • Okay, something like this: File encryptDir = new File (context.getFilesDir (), "Encrypt"); - falstaf
    • I'm creating it this way. sdPathEN = new File (sdPathEN.getAbsolutePath () + "/" + cr_dir_encr); if (! sdPathEN.exists ()) {sdPathEN.mkdirs (); } - Evilleks

    Well, the classic way to start likuksa folder name with (points)

    example:

    .i_am_invisible_folder
    • Not funny. - Evilleks
    • and what sobsno option does not like? - Gorets
    • Apparently, with this method, access to these directories by other applications remains possible. - falstaf
    • Why is this? by the same name will be available. - Gorets
    • Well, yes, by name will be available, while the question clearly states "that they are not visible and accessible in another application." - falstaf
