Make the internal storage monitor work correctly when internal storage is very large.

    private boolean mLowMemFlag=false;

    private Context mContext;

    private ContentResolver mContentResolver;

    int mBlkSize;

    long mBlkSize;

    long mTotalMemory;

    StatFs mFileStats;

    private static final String DATA_PATH="/data";

        //initialize block size

        mBlkSize = mFileStats.getBlockSize();

        //initialize total storage on device

        mTotalMemory = (mFileStats.getBlockCount()*mBlkSize)/100;

        mTotalMemory = ((long)mFileStats.getBlockCount()*mBlkSize)/100L;

        mStorageLowIntent = new Intent(Intent.ACTION_DEVICE_STORAGE_LOW);

        mStorageOkIntent = new Intent(Intent.ACTION_DEVICE_STORAGE_OK);

        checkMemory(true);
