declared in manifest file

<activity android:name="com.mani.staggeredview.demo.mainactivity" android:label="activity library"> </activity>

in class calling

import com.mani.staggeredview.demo.*; . . . . btn_naat.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) { intent myintent = new intent(getbasecontext(),com.mani.staggeredview.demo.mainactivity.class); startactivity(myintent); } });

i presume using volley library networking. seems haven't initialized requestqueue object:

if (mrequestqueue == null) { mrequestqueue = volley.newrequestqueue(getapplicationcontext()); }

add above code wherever have declared requestqueue object. seek this. should work.
