NullPointerException on make view about androidstaggeredgrid HOT 3 CLOSED

A stacktrace is great when accompanied with an explanation of how that exception was created. Can you help me out here?

from androidstaggeredgrid.

I was AndroidStaggeredGridView using programmatically in fragment.

and..

mSGV = new StaggeredGridView(ctx);
mSGV.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

footerView = inflater.inflate(R.layout.footer_trends_ave_list, null);
mSGV.setFooterView(footerView);

int margin = getResources().getDimensionPixelSize(R.dimen.margin);
mSGV.setItemMargin(margin);
mSGV.setPadding(margin, 0, margin, 0);

mSGV.setOnScrollListener(this);
mSGV.setAdapter(trendsAdapter);
layout.addView(mSGV);

and..
trendsAdapter.notifyDataSetChanged();

However, this error does not appear in any device android 4.4 (Kitkat) occurs in some devices.
