The Strange thing is, when i do it in slow way, all is fine, but when i do it in faster way to editText, database leak and cant open. My Trigger function is to delete when the user set 0/remove anything in editText(editText inside listview, multiple editText in row and more than 1 row) then the record is removed in database. When i add no any problem(using button), but for delete cz some reason i need to update manually each update in row. And there is case, when record not yet to save and user change to 0/remove data inside editText but this already in my exception.

So my question is why when i doing CRUD data in other function is fine, but in function remove editText got stuck. Only when i remove/set to 0(trigger to remove record) with fast, but when i doing it in slow way everything is alright.

just make little clear my problem almost same like : Getting error while executing getwritabledatabase() in android

So how i can init the db ? is something wrong with my db,

    private Context mContext;
    SQLiteDatabase db;        

    public DatabaseHelper(Context context ){
        super(context, DATABASE_NAME, null,DATABASE_VERSION );
        mContext = context;
        db = this.getWritableDatabase();
    }

    public static DatabaseHelper getInstance(Context ctx) {
        if (dInstance == null) {
            dInstance = new DatabaseHelper(ctx.getApplicationContext());
        }
        return dInstance;
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int i, int i1) {
        Log.w(DatabaseHelper.class.getName(),
                "Upgrading database from version " + i + " to "
                        + i1 + ", which will destroy all old data");

        db.execSQL(tableDBVersion.UPGRADE_TABLE_DBVERSION);
        onCreate(db);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL(tableDBVersion.CREATE_TABLE_DBVERSION);
        db.execSQL(tableDBVersion.SEED_TABLE_DBVERSION);
    }

Using Getting "Failed to open database" error when copying a sqlite database from assets In Android 4.2, still got same error. Idk if it correct way to implement to my code :

public DatabaseHelper(Context context ){
    super(context, DATABASE_NAME, null,DATABASE_VERSION );
    mContext = context;
    if(!checkDataBase()){
        db = this.getWritableDatabase();
    }
}

private boolean checkDataBase() {
    File databasePath = mContext.getDatabasePath(DATABASE_NAME);
    return databasePath.exists();
}
