Android - how to handle saving file on low device memory(Internal/External memory)

Question

How we can handle the file saving on low device memory(internal/Excternal memrory). I know if sufficient space is not available the OS will throw IOException but is there any way to handle this gracefully.

Answer 1

File path = Environment.getDataDirectory();
StatFs stat = new StatFs(path.getPath());
long blockSize = stat.getBlockSize();
long availableBlocks = stat.getAvailableBlocks();
return Formatter.formatFileSize(this, availableBlocks * blockSize);
