Question

Is there a way to directly access the sqlite database from the assets folder, or is it always necessary to first copy this db to the device data directory, in the app s database folder?

(Example - Environment.getDataDirectory ()+”/data/com.example.myapp/databases/myDb.db)

我问,因为我有一只大的 d(约11MB),必须随照运。在数据库被复制到数据目录之后,数据表将占用两倍的空间。我想避免这种情况。

此外,在安装了套件之后,能否删除该笔资产的内容? 这将有助于节省一些空间。

Answer 1

资产夹是汇编时间夹。您不能不复制。

Answer 2

yes you can delete the files from the database from the assets folder : you can use "android.resource://"+getPackageName() + "/" to access the folder and then use

File f=new File(_pathToAssestFolder,databasename);
        if(f.exists())
        {f.delete();
        }

但这在<代码>onCreate(功能>最后一行;
