android设备获取系统的存储空间和运行内存。

亲测可用！！！！

//运行内存
public  void getTotalRam(){
   //获取运行内存的信息
        ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);  
        MemoryInfo info = new MemoryInfo();  
        manager.getMemoryInfo(info);  
        StringBuilder sb = new StringBuilder();
        LogUtil.d("可用RAM:"+info.availMem/1024/1024 + "MB");
        LogUtil.d("总RAM:"+info.totalMem/1024/1024 + "MB");
}

//系统总存储大小
private void getTotalMemory() {
      //获取ROM内存信息
        //调用该类来获取磁盘信息（而getDataDirectory就是内部存储）
        final StatFs statFs = new StatFs(Environment.getDataDirectory().getPath());
        long totalCounts = statFs.getBlockCountLong();//总共的block数
        long availableCounts = statFs.getAvailableBlocksLong() ; //获取可用的block数
        long size = statFs.getBlockSizeLong(); //每格所占的大小，一般是4KB==
        long availROMSize = availableCounts * size;//可用内部存储大小
        long totalROMSize = totalCounts *size; //内部存储总大小
        LogUtil.d(" 可用ROM:" + availROMSize/1024/1024 + "MB");
        LogUtil.d(" 总ROM:" + totalROMSize/1024/1024 + "MB");
}
