Android gets phone Ram and Rom size

Solution:
1. Get Ram size
    //RAM memory size, return 1GB/2GB/3GB/4GB/8G/16G
    public static String getTotalRam(){         String path = "/proc/meminfo";         String ramMemorySize = null;         int totalRam = 0 ;         try{             FileReader fileReader = new FileReader(path);             BufferedReader br = new BufferedReader(fileReader, 4096);             ramMemorySize = br.readLine().split("\\s+")[1];             br.close() ;         }catch (Exception e){             e.printStackTrace();         }         if(ramMemorySize != null){












            totalRam = (int)Math.ceil((new Float(Float.valueOf(ramMemorySize) / (1024 * 1024)).doubleValue())); }
        return
 
        totalRam + "GB";
    }
2. Get Rom size
    //ROM Memory size, return 64G/128G/256G/512G
    private static String getTotalRom() {         File dataDir = Environment.getDataDirectory();         StatFs stat = new StatFs(dataDir.getPath());         long blockSize = stat.getBlockSizeLong();         long totalBlocks = stat.getBlockCountLong();         long size = totalBlocks * blockSize;         long GB = 1024 * 1024 * 1024;         final long[] deviceRomMemoryMap = {2*GB, 4*GB, 8*GB, 16*GB, 32*GB , 64*GB, 128*GB, 256*GB, 512*GB, 1024*GB, 2048*GB};







        String[] displayRomSize = {"2GB","4GB","8GB","16GB","32GB","64GB","128GB","256GB","512GB","1024GB","2048GB"};
        int i;
        for(i = 0 ; i < deviceRomMemoryMap.length; i++) {
            if(size <= deviceRomMemoryMap[i]) {
                break;
            }
            if(i == deviceRomMemoryMap.length) {
                i--;
            }
        }
        return displayRomSize[i];
    }
