将文件保存到内部存储（文档文件夹）权限被拒绝

Question

I try to save files on my smartphone. Since I have no SD card installed I must save the data to my internal memory. The user must have easy access to the data later, so I want to store in an easily accessible location. The following variant works without problems but is not easily accessible

File root = new File(getApplicationContext().getFilesDir(),"NAME");
        if(!root.exists()) root.mkdirs();

In this variant, I get the message that the access was denied.

Environment.DIRECTORY_DOCUMENTS

I also tried the following permissions:

READ_EXTERNAL_STORAGE WRITE_EXTERNAL_STORAGE

Does anyone know how to access these folders? The root directory would also be enough.

Thanks!

Besides asking for read and write permission in manifest for Android 6+ you should also add code to let the user confirm those permissions.

Google for runtime permissions.
