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

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:

Here is my code:

throw new Error("Error copying database");

}
}

}

@Override
public void onCreate(SQLiteDatabase db) {

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

}

// Add your public helper methods to access and get content from the
// database.
// You could return cursors by doing "return myDataBase.query(....)" so it'd
// be easy
// to you to create adapters for your views.

// Getting single contact
String getkword(String word) {
SQLiteDatabase db = this.getReadableDatabase();

Cursor cursor = db.query("data",
new String[] { "_id", "english", "korean" }, "english" + "=?",
new String[] { word }, null, null, null, null);
if (cursor != null)
cursor.moveToFirst();

String kword = cursor.getString(2);
// return contact
db.close();
return kword;

}

// Getting All Contacts
public Cursor getCursor() {
// Select All Query
String selectQuery = "SELECT * FROM " + "data";

SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);

// looping through all rows and adding to list

return cursor;
}

}


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

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


Thanks for the help!

Answer

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; 
}
