Answer 1

I'm using this method:

    public static final String SD_CARD = "sdCard";
    public static final String EXTERNAL_SD_CARD = "externalSdCard";
    private static final String ENV_SECONDARY_STORAGE = "SECONDARY_STORAGE";

    public static Map getAllStorageLocations() {
        Map storageLocations = new HashMap<>(10);
        File sdCard = Environment.getExternalStorageDirectory();
        storageLocations.put(SD_CARD, sdCard);
        final String rawSecondaryStorage = System.getenv(ENV_SECONDARY_STORAGE);
        if (!TextUtils.isEmpty(rawSecondaryStorage)) {
            String[] externalCards = rawSecondaryStorage.split(":");
            for (int i = 0; i < externalCards.length; i++) {
                String path = externalCards[i];
                storageLocations.put(EXTERNAL_SD_CARD + String.format(i == 0 ? "" : "_%d", i), new File(path));
            }
        }
        return storageLocations;
    }
