E/SQLiteLog(1893): (14) cannot open file at line 30176 of [00bb9c9ce4]

Question

I am using this tutorial to import a database into my App.

It runs fine on API 10,

but on API 17 it throws the following error:

EDIT EDIT EDIT EDIT I have set permission in my manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Thanks for the help!

While it may not be the problem, you should not be hard-coding the path of the application's internal storage, as this is ultimately dependent on implementation details of the Android installation, and so could change between devices/versions. One test you can do (if you are working with a debug rather than release build of your app) is to open an adb shell and type run-as com.example.koday and then use commands such as `pwd` and `ls` to explore your application's storage. — Chris Stratton, May 19 '13 at 17:46
@Chris Stratton I agree with your observation. Please could you suggest how to avoid hard coding the path?? I am sure that would solve the problem. BTW I use Eclipse + Emulator, the "dizionario7.sqlite" is created in the path "/data/data/com.example.koday/databases/", it this means anything... — Lisa Anne, May 19 '13 at 17:52

I think the problem is with the location of the db for different version of SDK. please try this

private static String DB_PATH = "";
public DataBaseHelper(Context context) {
    super(context, DB_NAME, null, 1);// 1? its Database Version
    if(android.os.Build.VERSION.SDK_INT >= 4.2){
        DB_PATH = context.getApplicationInfo().dataDir + "/databases/";         
    } else {
       DB_PATH = "/data/data/" + context.getPackageName() + "/databases/";
    }
    this.mContext = context; 
}

I used the same helper in my new project as another one I did and changed only the package name in the file path. In my first project it worked fine, in my second I got this error. How could my file path be fine for my first application but not my second given an identical testing environment? Further, why doesn't openDatabase() throw an exception if it does have an incorrect path? (Throws: SQLiteException if the database cannot be opened) – John Moffitt Jun 28 '13 at 06:34

@naveenprince - FYI: the code you put yields the same result: /data/data/PACKAGE_NAME/databases/ – Jadeye Sep 23 '13 at 11:12

A very wild guess is that you don't have required permissions in your android manifest. Besides, I am using the same piece of code for one of my projects replace checkDatabase() with:

private boolean checkDataBase() {

    File dbFile = new File(DATABASE_PATH + DATABASE_NAME);
    return dbFile.exists();
}

Also for the path use:

public static String getDBPath() {
    return Environment.getDataDirectory() + "/data/"
            + context.getPackageName() + "/databases/";
}

I have the following in my database I will try your edit and let you know! Thanks! – Lisa Anne May 19 '13 at 17:38
A very *uninformed* guess, as the file attempted to open is on the internal rather than external storage, so such permission is not needed. – Chris Stratton May 19 '13 at 17:42

I had the same error. I found out that I was entering the database while importing and updating the tables in the database. so I conclude that if you are updating your data base tables you can't use them at the same moment.
