android - Titanium install DB

Question

I have some trouble with installing a database with Ti.Database.install(). Here's what I'm doing:

• Open new default alloy project

• Add some code to controllers/index.js so the file looks like this

  var db = Ti.Database.install('/testimusDB.sqlite', 'testimusDB'); 
  var rs = db.execute('SELECT * FROM testimusTable');
  db.close();
  
  while (rs.isValidRow())
  {
    var name = rs.fieldByName('name');
    var age = rs.fieldByName('age');
    alert(name + ' is ' + age + 'years old');
    rs.next();
  }
  
  rs.close();
  
  $.index.open();
  

• create a DB with FF Plugin SQLite Manager called testimusDB.sqlite and copy it to the REsources Folder of the Project

• Start the App via Titanium Studio on a Samsung S3

What I get is

   Runtime Error: LOCATION: [101,19] ti:/invoker.js
   MESSAGE: Uncaught Error: Resources/testimusDB.sqlite SOURCE: return
   delegate.apply(invoker._thisObj_,args);

People with the same problem solved it by reducing the size of the DB (mine is 64 KB) or by using absolute path (I tried absolute-/relative- path and sqlite-/db-/sql- suffix). Any ideas how to solve this problem?

好的，我明白了：使用合金时不能使用 install()！（如果有人知道此信息的官方来源，请告诉我）。您需要使用模型来同步数据库。这个人和这个指南对我帮助很大。

感谢您的回答。

在操作结束时关闭与 db 的连接：

rs.close();
db.close();

数据库的大小无关紧要。我正在使用更大的一个：> 10MB。
