But getting error of StackOverFlowError.I have tried on best level last 2 to 3 days but not work perfectly.Can someone help me.How to do this.

hare is my Activity code
public void getActivityObjectId_Count() {
try {
dbhelper = new MyDbHelper(this);
SQLiteDatabase db = dbhelper.getReadableDatabase();


Cursor cursor2 = db.rawQuery("select count(activityObjId) from ActivityObjectList where " + "activityId" + " = ?", new String[]{strDescription});
if (cursor2 != null) {

cursor2.moveToFirst();

String strCount_ActivityObjectId = cursor2.getString(0);
intCount = Integer.parseInt(strCount_ActivityObjectId);

Log.e("intCount", "in getActivityObjectId = " + intCount);


}

cursor2.close();
db.close();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
