I'm developing an android app and it works in android 4.x version perfectly but in android 2.2 it stops working and does nothing without any error. From the debug I found that this problem is because of a join sql statement and when it comes to while statement it stops with no error.

selectedHospitalId = 3;        
cursor = G.dbHelper.myDataBase.rawQuery("Select Distinct HospitalDosageForm.DrugID," + "DrugsName.DrugName, HospitalDosageForm.IRC from HospitalDosageForm Join DrugsName On" + " HospitalDosageForm.DrugID = DrugsName.DrugID Where DrugsName.DrugNameType = 'A' "
+ "and HospitalDosageForm.DosageFormID = -1 and HospitalDosageForm.HospitalID = "
+ selectedHospitalId + " order by DrugsName.DrugName", null);
                G.drugs.clear();
                while (cursor.moveToNext()) {
                    drug = new Drug() {};
                    drug.DrugID = cursor.getInt(cursor.getColumnIndex("DrugID"));
                    drug.DrugName = cursor.getString(cursor.getColumnIndex("DrugName"));
                    drug.BrandID = cursor.getInt(cursor.getColumnIndex("IRC"));
                    drug.HospitalID = selectedHospitalId;
                    G.drugs.add(drug);
                }

It should return about 600 rows from my sqlite db.
I tested table view,thread,async and ... but I didn't find any solution.
I do appreciate for any help
