Continously check external storage to video stop recording

Question

I am working on a video camera app which will record a video but i want to stop the video recording when the user runs out of memory ,for that I will have to continuously check the size of video and sd card

The scenario is when I am recording the file size will change continuously so how do I stop recording video inside activity and how do i continuously check sdcard size

code to check sd card size is

StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath());        
            long blockSize = statFs.getBlockSize();
            long totalSize = statFs.getBlockCount()*blockSize;
            long availableSize = statFs.getAvailableBlocks()*blockSize;
            long freeSize = statFs.getFreeBlocks()*blockSize;

            long megAvailablenew = availableSize/ (1024 * 1024);
            Log.e("","Available MB : "+megAvailablenew+" avail "+availableSize)

refer this-

public long TotalMemory()//Environment.getExternalStorageDirectory().getAbsolutePath()
    {
        StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());   
        long Total = ( (long) statFs.getBlockCount() *  (long) statFs.getBlockSize()) / 1048576;
        return Total;
    }

public long FreeMemory()
{
    StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());
    long Free  = (statFs.getAvailableBlocks() *  (long) statFs.getBlockSize()) / 1048576;
    return Free;
}

public long BusyMemory()
{
    StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());   
    long Total = ( (long) statFs.getBlockCount() * (long) statFs.getBlockSize()) / 1048576;
    long Free  = (statFs.getAvailableBlocks() *  (long) statFs.getBlockSize()) / 1048576;
    long Busy  = Total - Free;
    return Busy;
}
