How do you check if the SD card is full or not so that your application can decide if it can continue to do its job i.e. write to external storage or notify the user that storage has run out of space.

推荐答案

使用体statfs ，并通过外部存储目录的路径构造，并且可以调用功能，为 getAvailableBlocks（）和 getBlockSize（）在体statfs 对象。

Use StatFs and pass the path of the external storage directory to the constructor and you can call functions such as getAvailableBlocks() and getBlockSize() on the StatFs object.
