Android Sqlitedb Doesn't Finish Adding Values

My SQLiteDatabase is giving me some trouble. When the user closes the app, in onPause() an AsyncTask begins to save the data. I don't know if this is the best way to do it, but the

Solution 1:

I fixed this by creating an IntentService with an AsyncTask inside of it, and calling it within onPause. It works error-free now. Here's the code in onPause:

    Intent saveIntent = newIntent(this, SaveService.class);
    startService(saveIntent); 

And here's my SaveService class:

publicclassSaveServiceextendsIntentService
{
    private ArrayList<Ingredient> ingredientsArray;
    private ArrayList<Unit> unitsArray;
    private DatabaseHelper dbHelper;

    publicSaveService(String name) 
    {
        super(name);
    }

    publicSaveService() 
    {
        super("SaveService");
    }

    @OverrideprotectedvoidonHandleIntent(Intent intent) 
    {
        //save data to database
        dbHelper = newDatabaseHelper(getApplicationContext());
        ingredientsArray = QuickBakeConverterPro.ingredients;
        unitsArray = QuickBakeConverterPro.units;

        newSaveAllTask().execute();
    }

    privateclassSaveAllTaskextendsAsyncTask<Void, Void, Void>
    {
        @Overrideprotected Void doInBackground(Void... args) 
        {
            //open databasetry 
            {
                dbHelper.openDatabase();
            }catch(SQLException sqle)
            {    
                throw sqle;  
            }

            dbHelper.deleteAll();

            //add all ingredients & unitsfor (inti=0; i < ingredientsArray.size(); i++)
                dbHelper.addIngredient(ingredientsArray.get(i));
            for (inti=0; i < unitsArray.size(); i++)
                dbHelper.addUnit(unitsArray.get(i));

            dbHelper.close();

            returnnull;
        }
    }//SaveAllTask
}//class SaveService
