android - How to delete a whole folder and content?

Question

I want the users of my application to be able to delete the DCIM folder (which is located on the SD card and contains subfolders).

Is this possible, if so how?

Answer 1

You can delete files and folders recursively like this:

void deleteRecursive(File fileOrDirectory) {
    if (fileOrDirectory.isDirectory())
        for (File child : fileOrDirectory.listFiles())
            deleteRecursive(child);

    fileOrDirectory.delete();
}
