Answer 1

You can use the Method getFilesDir() or getDatabasePath in an Activity-Class to get this Folder.

Answer 2

I used...

String destPath = getFilesDir().getPath();
destPath = destPath.substring(0, destPath.lastIndexOf("/")) + "/databases";

Answer 3

Used by SQLiteAssetHelper:

 String path = mContext.getDatabasePath(mName).getPath();

At this time, the database doesn't exist. I think the String just takes the internal path and adds the appropriate modifiers. In fact, this seems to work just fine:

context.getDatabasePath("a").getParentFile()

Basically, you don't need to have a real database created, just ask it for one.

Answer 4

Create an empty DB, get the path with getDatabasePath(), then overwrite it with your own.

Answer 5

You can use getDatabasePath method in your Helper class:

public class MyDatabase extends SQLiteAssetHelper {

    private static final String DATABASE_NAME = "wl.db";
    private static final int DATABASE_VERSION = 1;  
    public String databasePath = "";    

    public MyDatabase(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);

        // you can use an alternate constructor to specify a database location
        // (such as a folder on the sd card)
        // you must ensure that this folder is available and you have permission
        // to write to it
        // super(context, DATABASE_NAME, context.getExternalFilesDir(null).getAbsolutePath(), null, DATABASE_VERSION);

        databasePath = context.getDatabasePath("wl.db").getPath();
    }
