i've tried build app on top of opensource project. basic function use gridview show couple of images. following code snippet. comment line original code. in original code, images.imagethumburls string array of urls , size(images.imagethumburls.length) 99. i'd replace original urls own version , did. there error. please see log.
according log, seems limit getview 99(the original code). aside changing getcount, there else need do?
in createview method:
mgridview.getviewtreeobserver().addongloballayoutlistener( new viewtreeobserver.ongloballayoutlistener() { @override public void ongloballayout() { if (madapter.getnumcolumns() == 0) { final int numcolumns = (int) math.floor( mgridview.getwidth() / (mimagethumbsize + mimagethumbspacing)); if (numcolumns > 0) { final int columnwidth = (mgridview.getwidth() / numcolumns) - mimagethumbspacing; madapter.setnumcolumns(numcolumns); madapter.setitemheight(columnwidth); if (buildconfig.debug) { log.d(tag, "oncreateview - numcolumns set " + numcolumns); } } } } }); imageadapter class:

be carefull, when returning value on getcount() greater number of items @ adapter (usually fill cells) need check if current bounds never bypassed, , if return empty view (or 1 background).
your code:
public int getcount() { //return images.imagethumburls.length + mnumcolumns; return datastore.photosinfooftag.total + mnumcolumns; } should return datastore.photosinfooftag.total
also, not use static things this, should use list instead data of adapter.
