在MarshMallow中获取内部和外部内存大小 [英] Get Internal and External Memory size in MarshMallow

问题描述

我正在尝试在应用程序中显示内部和外部(SD卡)内存的大小.我的代码在kitkat和api以下版本中工作正常，但是我的应用程序在棉花糖或棒棒糖中崩溃了.这是我的代码..

I am trying to show the size of Internal and External(SD card) memory in my application.My code is working fine for kitkat and below api versions but My app is crashing in Marshmallow or lollipop .Here is my code ...

 public static long getAvailableInternalMemorySize() 

{
        File path = Environment.getDataDirectory();
        StatFs stat = new StatFs(path.getPath());
        long blockSize = stat.getBlockSize();
        long availableBlocks = stat.getAvailableBlocks();
        return availableBlocks * blockSize;
    }

    public static long getTotalInternalMemorySize() {
        File path = Environment.getDataDirectory();
        StatFs stat = new StatFs(path.getPath());
        long blockSize = stat.getBlockSize();
        long totalBlocks = stat.getBlockCount();
        return totalBlocks * blockSize;
    }

    public static long getAvailableExternalMemorySize() {


        String secStore = System.getenv("SECONDARY_STORAGE");
        File path = new File(secStore);
        StatFs stat = new StatFs(path.getPath());

        long blockSize = stat.getBlockSize();

        long availableBlocks = stat.getAvailableBlocks();

        long total = availableBlocks * blockSize;

        return total;
    }


    public static long getTotalExternalMemorySize() {

        String secStore = System.getenv("SECONDARY_STORAGE");
        File path = new File(secStore);
        StatFs stat = new StatFs(path.getPath());

        long blockSize = stat.getBlockSize();

        long availableBlocks = stat.getBlockCount();

        long total = availableBlocks * blockSize;


        return total;

    }

您能告诉我解决方案以获取上述api版本中的内存大小吗??

Can you tell me the solution to get the memory sizes in above api versions...?

推荐答案

在lolipop或marshmallo中，您必须使用
Environment.getExternalStorageDirectory().getAbsolutePath();

In lolipop or marshmallo you must use
Environment.getExternalStorageDirectory().getAbsolutePath();

获取外部存储路径，而不是 System.getenv("SECONDARY_STORAGE");

to get external storage path instead of System.getenv("SECONDARY_STORAGE");

请参阅beolw代码以获取> android 5.0中的外部和内部存储

Refer beolw code for get external and internal storage in >android 5.0

public static String getTotalInternalMemorySize() {
            File path = Environment.getDataDirectory();
            StatFs stat = new StatFs(path.getPath());
            long blockSize = stat.getBlockSize();
            long totalBlocks = stat.getBlockCount();
            return formatSize(totalBlocks * blockSize);
        }

        public static String getAvailableExternalMemorySize() {
                File path = Environment.getExternalStorageDirectory();
                StatFs stat = new StatFs(path.getPath());
                long blockSize = stat.getBlockSize();
                long availableBlocks = stat.getAvailableBlocks();
                return formatSize(availableBlocks * blockSize);
            }
