Android13获取存储空间大小

内部存储

1、总大小

public static long getInternalStorageSize(Context context) {
    File filesDir = context.getFilesDir();
    return filesDir.getTotalSpace();
}

2、可用空间大小

public static long getFreeSpace(Context context) {
    File filesDir = context.getFilesDir();
    return filesDir.getFreeSpace();
}

扩展TF卡

1、总大小

public static long getExternalStorageSize(Context context) {
    StorageManager storageManager = context.getSystemService(StorageManager.class);
    for (StorageVolume volume : storageManager.getStorageVolumes()) {
        if (volume.isRemovable()) {
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.R) {
                File directory = volume.getDirectory();
                LogUtils.i("fileUtils", "directory = " + directory.getAbsolutePath());
                LogUtils.i("fileUtils", "directory = " + directory.getTotalSpace());
                return directory.getTotalSpace();
            }
        } else {
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.R) {
                File directory = volume.getDirectory();
                LogUtils.i("fileUtils", "false directory = " + directory.getAbsolutePath());
                LogUtils.i("fileUtils", "false directory = " + directory.getTotalSpace());
            }
        }
    }
    return 0;
}

2、可用空间大小

public static long getExternalStorageFreeSize(Context context) {
    StorageManager storageManager = context.getSystemService(StorageManager.class);
    for (StorageVolume volume : storageManager.getStorageVolumes()) {
        if (volume.isRemovable()) {
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.R) {
                File directory = volume.getDirectory();
                LogUtils.i("fileUtils", "directory = " + directory.getAbsolutePath());
                LogUtils.i("fileUtils", "free = " + directory.getFreeSpace());
                return directory.getFreeSpace();
            }
        } else {
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.R) {
                File directory = volume.getDirectory();
                LogUtils.i("fileUtils", "false directory = " + directory.getAbsolutePath());
                LogUtils.i("fileUtils", "false directory = " + directory.getTotalSpace());
            }
        }
    }
    return 0;
}

单位转换

public static String storageSizeConversion(long size) {
    DecimalFormat df = new DecimalFormat("#.00");
    String fileSizeString = "";
    if (size < 1024) {
        fileSizeString = df.format((double) size) + "B";
    } else if (size < 1048576) {
        fileSizeString = df.format((double) size / 1024) + "K";
    } else if (size < 1073741824) {
        fileSizeString = df.format((double) size / 1048576) + "M";
    } else {
        fileSizeString = df.format((double) size / 1073741824) + "G";
    }
    return fileSizeString;
}
