我该如何检查，看看有多少MB或GB留在Android设备上？我使用JAVA和Android SDK 2.0.1。

How do I check to see how much MB or GB is left on the android device ? I am using JAVA and android SDK 2.0.1.

有没有什么系统服务，将公开这样的事情？

Is there any system service that would expose something like this ?

推荐答案

尝试，code

StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath());
long bytesAvailable = (long)stat.getBlockSize() *(long)stat.getBlockCount();
long megAvailable = bytesAvailable / 1048576;
System.out.println("Megs :"+megAvailable);

From有

UPD： getBlockCount（）的 - SD卡返回大小; getAvailableBlocks（）的 - 返回块仍在访问正常的节目数量（感谢乔）

UPD: getBlockCount() - return size of SD card; getAvailableBlocks() - return the number of blocks that are still accessible to normal programs (thanks Joe)
