如何知道Android的内部存储器容量？ [英] How to know internal memory size in android?

问题描述

这是我的code，

private String memSize(String path){
    StatFs stat = new StatFs(path);
    long blockSize = stat.getBlockSize();
    long availableBlocks = stat.getAvailableBlocks();
    long freeBlocks = stat.getFreeBlocks();
    long countBlocks = stat.getBlockCount();
    String fileSize = Formatter.formatFileSize(this, availableBlocks * blockSize);
    String maxSize = Formatter.formatFileSize(this, countBlocks * blockSize);

    String info = path.toString()
                    + "\nblockSize : " + Long.toString(blockSize)
                    + "\navailableBlocks : " + Long.toString(availableBlocks)
                    + "\nfreeBlocks : " + Long.toString(freeBlocks)
                    + "\nreservedBlocks : " + Long.toString(freeBlocks - availableBlocks)
                    + "\ncountBlocks : " + Long.toString(countBlocks)
                    + "\nspace : " + fileSize + " / " + maxSize
                    + "\n\n";
    return info;
}

我和路径来测试我的功能 /数据和 / SD卡和它作品 - 但是，当路径为 / （我的理解是根路径），这就是结果。

I test my function with path /data and /sdcard and it works
But when path is / (I understand it is root path), this is result.

• 块大小：4096
• availableBlocks：0
• freeBlocks：0
• reservedBlocks：0
• countBlocks：0
• 空间：0.00B / 0.00B

我觉得根路径是超级用户区。可能需要一定的权限才能访问。
我的手机已经扎根。你能告诉我，我应该做的下一步？

I think root path is SuperUser area. May need some permission to access.
My phone is already rooted. Could you show me what I should do next step ?

感谢你。
