本文介绍了一个用于检查外部存储是否足够存放指定大小文件的方法。通过获取当前可用的块数量及每个块的大小，来判断是否有足够的空间。此方法适用于需要预先检查文件存储空间的应用场景。
public static boolean isEnoughSpace(long size){
if(Environment.getExternalStorageDirectory().equals
(Environment.MEDIA_MOUNTED)){
File path = Environment.getExternalStorageDirectory();
StatFs statFs = new StatFs(path.getPath());
long blockSize = statFs.getBlockSize();
long availableBlocks = statFs.getAvailableBlocks();
if(size < availableBlocks * blockSize ){
return true;
}else{
return false;
}
}
return false;
}
if(Environment.getExternalStorageDirectory().equals
(Environment.MEDIA_MOUNTED)){
File path = Environment.getExternalStorageDirectory();
StatFs statFs = new StatFs(path.getPath());
long blockSize = statFs.getBlockSize();
long availableBlocks = statFs.getAvailableBlocks();
if(size < availableBlocks * blockSize ){
return true;
}else{
return false;
}
}
return false;
}
